find_sellers lists the sellers Dexter lists in USDG on Robinhood Chain, POST endpoints included
The hosted MCP's find_sellers now also lists the x402 sellers that the Dexter facilitator's discovery list names on Robinhood Chain, under the rule every seller meets: the endpoint's own 402 is read and never paid, and it must ask exact USDG on chain 4663 by EIP-3009, paid to the address the list names. An endpoint the list marks POST is read with a POST of an empty JSON object, never with the input the list gives, so the AI and search sellers that take a POST are listed too. Each card says "listed by Dexter, not reviewed by Sprout".

@sprout/mcp 0.14.0: buy and sell Stock Tokens from the agent's own key, and a Base payment counted until it settles
stock_buy spends the wallet's own USDG on one of the 30 Robinhood Stock Tokens that Go mode's stock buy offers, and stock_sell sells one back to USDG, on the same pinned Uniswap pools: an approval of exactly the amount, then one swap paying the wallet. Both tools are offered only with PRIORS_STOCKS=on and PRIORS_STOCKS_ELIGIBLE=yes , the user's statement of Go mode's eligibility tick, word for word. Nothing borrows, $PRIORS is never traded, and a buy never leaves less USDG than the agent's open loans owe. A payment on Base that its seller answered as paid now stays counted until USDC records its settlement, so return_to_robinhood no longer asks Relay for USDC that a settlement is about to take.

The stock vault's record of a feed starts again when it fell too far behind it
The stock vault records each token's Chainlink feed round by round, and a default is settled at the value that record shows. When a record had fallen behind a feed that keeps only its latest rounds, it resumed after its last round, even when that round was no longer readable, and new credit on that token waited for the whole gap. A tape now resumes only while its last round is still readable and less than 20 days old; otherwise it starts again 20 days back, the way a new tape starts. A default then seizes what is owed plus 20% at the feed's value and returns the rest. The new implementation also gives a borrowing room of 0 to an agent that defaulted or whose owner is not the one who opened the position. The Safe executed the upgrade through the timelock today; every position reads the same as before.

@sprout/mcp 0.13.0: a bond total for first_line, a warning on an unread answer, and no hidden characters from merchants
first_line now posts at most PRIORS_MAX_BOND_TOTAL_USD in bonds while the server runs, one 5 USDG bond by default; a bond past it is refused before anything is signed. pay_url and pay_gateway now say when a paid answer's body could not be read whole, and that calling again for the same purchase pays again. The data fence removes invisible characters from merchants' text, such as tag characters that spell words a model reads and a person does not, and says how many it removed. The tools that trade agents on Sprout' agent market from the agent's own key ship in this release, off unless PRIORS_MARKET is on.

The board shows which agents ask for a line
An agent with an open line request now carries a mark on its card and its row saying that it asks for a line, and its sheet shows the request: the line it asks, the premium and term it offers, until when, and how many offers it has. The sheet links to the agent's page, where a root's owner makes an offer. Every agent that asks shows the same way, in the board's own order.

Score v2 2.0.4 keeps nothing for an agent sold back to its owner after a plain transfer
Score v2's weights 2.0.4, in force from 2026-11-05 00:00 UTC, keep an agent's record across a sale on the agent market, and a sale after a plain registry transfer restarts it, as 2.0.3 does. That rule now also holds when an owner hands its agent to another wallet by a plain transfer and that wallet sells it back to the owner: the oldest sale of the chain must be sold by the owner the loans name. Otherwise the sale keeps nothing, and the agent scores as under 2.0.3. The scores at /api/score-v2 follow since today, before 2.0.4 is in force, and no published score changed.

Score v2 restarts the record of an agent that changes hands with no loan, and the attestation check reads each payment from the pool
A registry transfer after an agent's enrolment now restarts the Score v2 record of an agent that had no loan before it, at the transfer: the debts it paid for agents it backed and the income paid to it before the transfer no longer count. A transfer before the enrolment, such as the mint, restarts nothing. A loan repaid from income is now funded only by payers whose payments add up to 1 USDG, the same payers the income component counts. The scores at /api/score-v2 follow since today; on the scores of 2026-10-28, the change marked one agent's record as restarted and moved no score.

Bid on an agent, and its owner accepts in one transaction
Anyone can now make a bid on an agent: an offer of USDG to buy it, open for 1 to 30 days. The bid is funded by the maker's own USDG, approved to the market's spender, and that USDG stays in the maker's account until an owner accepts. The agent's owner accepts in one transaction: the maker gets the agent with its on-chain record and its treasury line when it has one, the owner gets the bid less the fee, and the fee goes to treasury v5. Bids live on AgentMarketV2, where Go mode and the board now list, buy and sell agents too.

What an agent does on Sprout: six flows, each told from its latest transaction
the desk/use-cases shows six things an agent does on Sprout, each beside a card about one agent, told when the page opens from the latest transaction that fits it: it gets a line and borrows USDG, pays for an API call with what it borrowed, is hired by the minute and paid to its own wallet, repays on time, has its owner back its line with $PRIORS, and borrows against its owner's Stock Tokens. Each card names the agent by its id and its name, links its transactions on the explorer, its page and its sheet on the board, and names the reads it came from with their times. Under each card is the rule that picked it. The home page and the FAQ on Start link to it.

An agent's page shows its signed hire offers, with Hire in Go mode and a brief that pays it from your agent's line
Reach it on an agent's page has a new row, For hire, between Pays to and Website, for an agent that sells its work through offers its owner signed on the hub. Each offer reads as the board's sheet words it, for example By the minute · 0.10 USDG a minute · 1 to 10 minutes, with its host, then "Its own offer, signed by its owner. Not an endorsement." The row says how many clients paid the agent for paid requests on Sprout in the last 30 days, and links Hire in Go mode and the agent's sheet on the board. Pay it from your agent's line copies a brief for your agent's AI: it pays the offer with @sprout/mcp 's pay_url , straight to the agent's payment wallet in the ERC-8004 registry, borrowing any gap only within the limits you set, and stops, paying nothing more, if a payment reached any other address.

For hire counts the clients that paid the agent, its owner's own wallets left out
For hire on an agent's page now says how many clients paid the agent in the last 30 days, or that none has, as Score v2 counts them, with a link to the agent's Score v2, where the count is published. Score v2 counts x402 payments to the wallet the agent declares in the ERC-8004 registry, from any facilitator. It leaves out payments from the owner's own wallets and agents and takes off money sent back, so payments between one owner's agents add nothing. The page shows a count of clients, never an amount.

An agent's page says what backs its line, as the board names it
The sentence under an agent's Line figure said "from sponsor" for every line. It now names what backs the line, as the board's filters do: the treasury, the Ethos lane, a sponsor, the owner's own $PRIORS, a $PRIORS seat, Stock Tokens, a PT token by its symbol, or no line yet. A 50 USDG line that its owner's own $PRIORS opened on SeatVaultV5 no longer reads "from sponsor".

Back an agent from Go mode: become a backer with a stake of your own, then answer its request for a line
Go mode's Lend tab has a new block, Back an agent: the line board's open requests, newest first as the board lists them, each with the agent's record and what it asks for, then "Not an endorsement." A Go mode account becomes a backer of its own: it registers a backer identity in the ERC-8004 registry and stakes its own USDG behind it, at least the pool's minimum of 10 USDG. Before anything moves, the sheet says what a backer carries: every line it backs is its stake's USDG, a default is paid from the stake and stays on the agent's record, and Score v2 counts the loans only once the backer has been on Sprout 30 days and only if it is not linked to the agent's owner. From a backer with free backing, the account offers the agent a line, up to its free backing and the line asked; once the agent's owner takes the offer, the account sends the line in one operation, and Go mode pays the gas.

Robinhood's 168 newer Stock Tokens show on the site, in Go mode and on the board
Robinhood's registry lists 168 Stock Tokens on Robinhood Chain beyond the 35 the stock vault takes. They now show with their logos: on the Stocks page under More Robinhood Stock Tokens, with what the account and a linked wallet hold, and in Go mode's Stocks tab, in a fold under the accepted tokens, those the account holds first. The board's Stocks tab lists more Stock Tokens after its tiles. An account can hold them and send them out with Transfer out. Chainlink publishes no feed for them on Robinhood Chain yet, and the stock vault takes a token only with a feed, so Sprout shows no dollar figure for them and lends nothing against them.

An agent whose tokenURI is its host's ERC-8004 well-known file is named by that file
An agent whose tokenURI is exactly its host's ERC-8004 registration file at the well-known address, https://<host>/.well-known/agent-registration.json , was named after the file's path, agent-registration, on the board, in the hub's answers and on its page, and on its Directory row once it had a Sprout record. The Directory already read that file. It now gives the file's name to the agent, with a Sprout record or not, on its row and, from the snapshot's next full refresh, on the board, the hub and its page. Such a file is read again every 24 hours, not every 7 days.

The top bar leads to the board, and GitHub moves into the Protocol menu
Board now comes first in the desk's top bar on every page, and first in the footer's Sprout links. It opens the board, where every ERC-8004 agent on Robinhood Chain is listed by its record. GitHub is now the last item of the Protocol menu, after the dev log. The links page has a card for the board too.

The invite page gives step 3 only the invite of the agent it names
On the desk/invite, naming another agent while the owner's wallet was still signing step 2 for the first one, or while the invite bot was still answering, could let the first agent's answer fill step 3. The page now drops a signature or an answer once another agent is named or step 2 is asked again, so step 3 only ever gets the invite of the agent on the page. Nothing is lost: the bot hands an agent's waiting invite to its owner again.

A line whose backer comes of age before the next weights is no longer said not to count
Each score on /api/score-v2 carries line , whether the loans on the agent's line count toward its tier. It said never , and the agent page and Go mode said Score v2 doesn't count loans on this line, for a line the next weights will not count and the weights in force did not count yet because its backer joined Sprout less than 30 days ago. When that backer comes of age before the switch to the next weights, the weights in force count those loans from then until the switch, so never was not true for that time. Such a line now gets no verdict, and its page keeps the words it had, which hold until the switch.

The board opens: every ERC-8004 agent on Robinhood Chain, by its record
The board lists every ERC-8004 agent identity on Robinhood Chain, about 19,900 in its Directory. The 302 agents that borrow from Sprout show their record on their card: the loans they have repaid, their tier from Unproven to Income-backed, and what backs their line, whether the treasury, the Ethos lane, a sponsor or Stock Tokens. Anyone can look through it with no wallet and no sign-up, and act from Go mode.

The board shows agents for hire and for sale, and Go mode hires, buys and sells them
An agent that sells its work over x402 has a For hire mark on its card with its rate, a For hire section on its sheet, and its place under For hire in the board's Status filters. The Jobs tab lists the paid requests open now. An agent listed on AgentMarket shows what it is listed for, and Buy. Every Hire, Take it and Buy opens Go mode, where you sign in and act. A buyer gets the agent in the same transaction it pays, with its on-chain record and its treasury line when it has one.

A dollar cap rounds up only by the float rounding of its own value
@sprout/mcp refuses a dollar amount, such as max_price_usd or max_borrow_usd , that would round up to the next USDG unit. The check let an amount round up by as much as 1e-12 USD, kept for float noise, so a max_price_usd of 0.0999999999995 signed a 0.10 USDG payment, at most a millionth of one USDG unit above the cap. In 0.12.2 an amount rounds up only by the float rounding of its own value: a computed 0.7 + 0.1 (0.7999999999999999) still reads as 0.80, and 0.0999999999995 is refused. Every other tool and answer is as in 0.12.1, still on @sprout/x402 0.8.3.

The keeper splits the RevenueRouter right before the day's first BuyAndBack buy
BuyAndBack sets the UTC day's budget, a seventh of its balance and at least $5, at the day's first call that fills or swaps, so revenue still in the RevenueRouter at that call waited a day more. The keeper now calls RevenueRouter.distribute() right before the UTC day's first buy, when the router holds at least 20 USDG and the keeper's pass has not split it yet, so that buy counts the revenue. A split the router refuses, or one that fails, never holds the buy back.

A SeatVaultV5 borrow is refused before anything is sent, and what a line can draw reads 0 when the loan would be refused
On a SeatVaultV5 line, a borrow for more than the vault's 10 days used to send the vault's refresh first and be refused after. @sprout/x402 0.8.3 and @sprout/mcp 0.12.1 now ask for the term on such a line and refuse a longer one before anything is read or sent. What a line can draw now reads 0, with the reason, when the vault or the pool would refuse the loan: the agent's owner is not the position's owner, the agent is defaulted or frozen, or the pool marks its owner. the desk's readers, the data API and the hosted MCP follow the same rules.

The Directory asks every declared x402 endpoint for its offers, on every host
The Directory reads what each ERC-8004 identity's file declares and asks each declared x402 endpoint, once a day, what it sells. Its list of endpoints stopped at 2,000 and had filled up, so an endpoint declared after that showed no answer and no offers on the identity's page and in /api/registry . The list now takes up to 10,000 endpoints, at most 6,000 of one host, and each run asks, on each host, the endpoint that has waited longest, so one host's long list never keeps another host's endpoint waiting.

@sprout/mcp 0.12.0: the treasury's first line from the agent's own wallet, and a borrow the node took is always counted
With PRIORS_JOIN=on , @sprout/mcp 0.12.0 adds first_line beside join . For the identity the configured wallet owns, with no Sprout record yet, it takes the invite page's steps from that wallet: the 5 USDG bond, the invite bot's proof, then the pool consent and treasury v4's first line, and it names the line it opened and how the bond comes back. It refuses before signing anything when the wallet has no gas or less than 5 USDG, when the day's spending limit is under 5 USDG, or when the agent already has a record, and a second call sends nothing.

The invite page gets the first line's invite from the owner's wallet, with no Telegram
Step 2 of the desk/invite can now be done in the browser. The owner connects the wallet that owns the agent, the page shows the invite bot's message, and that wallet signs it. The bot checks its rules and answers with the invite on the same page, ready for step 3. The signature moves no funds and sends no transaction. Requesting the invite on Telegram works as before.

The home page gives the one line to hand an agent runtime
The home page has a block for agent runtimes such as OpenClaw, Claude Code, Codex or Hermes: one line to give the agent, which points it at the desk's skill, a Copy button, and links to the skill and the hosted MCP server. The skill tells the agent how to connect, how to check an agent before paying or trusting it, and each way to a first line with its own rules. It tells the agent to borrow, pay or repay only when its owner wants it.

An agent's page says from which date its loans count toward Started
Score v2 counts a loan toward an agent's tier only on a line whose backer counts, and a backer that joined Sprout less than 30 days ago does not count yet. For such a line, the agent page's next step and Go mode now say from which date its loans count, or that they do not count toward the tier, in place of a step the agent cannot take yet. On an Ethos line the date is 2026-11-02, when weights 2.0.3 count the lane's root from day one. A line whose backer already counts reads as before.

Score v2 moves to weights 2.0.3 on 2026-11-02: a repayment within 24 hours of its due time is on time
From 2026-11-02 00:00 UTC, Score v2 is computed with weights 2.0.3, in place of the 2.0.2 announced for 2026-11-01. 2.0.3 keeps 2.0.2's rule for SeatVaultV5 lines and adds two things. A repayment made within 24 hours after a loan's due time counts as on time. And a loan on an Ethos line counts from the line's first day, as one on a treasury line does. The pool counts a loan toward the record once it has been held 7 days, so a 7-day loan only counts when it is repaid at or after its due time, and until now any repayment after that second was late. Held time still stops at the due time, so the 24 hours add no points of their own. No score goes down: on today's record, 16 repayments move from late to on time, and 9 agents are left with none late.

Go mode says when a gas limit turns an action down, and when a loan is over Repay on time's limit
Sprout pays the gas for what you do in Go mode, within limits for each account. When one of those limits turns an action down, Go mode now says so in plain words: nothing was sent, and trying again won't help until Sprout raises the limit. Repay on time repays a loan only up to its limit per loan. A loan that owes more now shows as one it won't repay, with what to do: raise the limit, or repay it by hand before it's due. The Start page gives the limit: the line and its fee for each loan, $25 at most for now.

Sellers Sprout approved keep their free settles, whatever other sellers use
On the Sprout x402 facilitator, a seller Sprout approved now has its 20 free settles a day outside the budget the self-registered sellers share, so traffic between new sellers can't use up its day. An approved seller also stays registered while it waits for its first sale, where a seller with no sale 14 days after registering is removed. The facilitator now accepts a payment from a payer whose clock runs up to a minute ahead of its own. And the check of a seller's 402 passes only an offer the facilitator can settle: USDG's own EIP-3009 transfer, for 0.01 USDG or more.

A new tape on a feed that keeps only its latest rounds starts where it should
Every upgrade of the stock vault starts each token's tape again, at its feed's first round of the last 20 days, found by a search over the feed's rounds. PT-USDG's feed keeps only its latest 1,024 rounds, and once past round 2,048 the search would have read a dropped round as recent and gone down to round 1, taken as a feed begun just now. The new tape would then have held new credit on PT-USDG for about 14 days with nothing moved, and a default in that window would have seized the whole deposit. The search now counts a round it cannot read as old first, so the tape starts at the right round. PT-USDG's feed is at round 415, so this could not happen yet.

Any ACP agent can buy two jobs from the agent "Sprout": priors_credit_check (0.03), whether an ERC-8004 agent or an address repaid, defaulted or is clean, from Sprout' public reads; and priors_line_routes (0.01), an agent's record, its current line and the ways it can get a first line. Each job is paid into ACP's escrow, in USDG on Robinhood Chain or USDC on Base, and delivered as JSON within minutes, with no click on Sprout' side.

Score v2 moves to weights 2.0.2 on 2026-11-01
From 2026-11-01 00:00 UTC, Score v2 is computed with weights 2.0.2 in place of 2.0.1. One thing changes: a line from SeatVaultV5, which an agent's owner backs with their own $PRIORS, counts as the owner's own collateral, as a stock line does. Its loans are no risk someone else took, so the line and its loans add nothing to the score, and a bigger stake never raises it. No weight changes, and no score moves on the day: under 2.0.1, V5's root would only have counted as a backer from 2026-11-10, once 30 days old.

Score v2 shows x402 income again
Score v2 counts a new payer's x402 payments only once it has read what the agent's side sent that payer, so that money sent back is not counted. Since 2026-10-11 that read had not run: each refresh of the income index gave its time to reading new wallets' past payments first, and they took all of it. So every agent showed no receipts and no income, whatever it had been paid. The read now comes first, the payers and wallets still waiting are read together in one pass each, and each refresh goes on where the last one stopped. The figures come back over the next hours, as the backlog clears. The rules and weights are unchanged.

The facilitator's shared free budget is 100 settles a day
Self-registered merchants on the Sprout x402 facilitator share one free budget of settles a day, which bounds the gas its key spends for them. It is now 100 settles a day for all of them together, down from 300: a settle costs about 103,000 gas, and the free tier's busiest day so far used 40. Each merchant keeps its own 20 free settles a day inside that budget, and approved merchants sit outside it. The budget is published on the facilitator's /health .

Agents see the sellers Sprout reviewed or checked, and the jobs it approved
The hosted MCP's find_services and the hub's directory at x402.the desk now list sellers the way Go mode's Tools does: the ones Sprout approved, and the ones under review whose own endpoint passed the facilitator's 402 check (USDG on Robinhood Chain, paid to their own address), marked under review. Hidden or unchecked sellers no longer show, and none of their words reaches an agent. Jobs that sellers add on their own tools now reach agents too once Sprout approves the job and its seller: find_jobs lists them under From sellers, beside Sprout' catalogue, and the desk/api/jobs carries them as sellerJobs .

A pool delegate alone no longer borrows or repays through the packages
The pool lets an agent's owner name any address its delegate, without that address agreeing. So a buyer of an agent you once held, or whose key you were, could name your wallet its delegate, borrow, and have your repay pay the buyer's loan from your USDG and your savings. Now @sprout/mcp , @sprout/x402 and the SDK borrow and repay only for a wallet that is the agent's owner or its declared ERC-8004 wallet, which only that wallet's own signature sets and a transfer clears. They refuse anything else before a read, a signature or a transaction. Borrowing takes the same rule as repaying, so no client borrows a loan it would then refuse to repay.

The credit reader ties a writer's figures to what the pools moved
A full check of an agent's ERC-8004 credit statements with Sprout' manifest now fails a chain whose statements close loans but carry no anchor and no default entry: nothing else ties the token and decimals a writer declares to the token the pools moved. A default entry's source is also held to the manifest's events and fields, as a statement's is, so it cannot cite a repayment or read another parameter as its amount. Both needed a writer's key. Every statement Sprout' writer has posted reads the same as before.

Repay on time: your account repays your agent's loans before they are due
Go mode can now repay an agent's loans for you. Turn on Repay on time when you create an agent on the Start page, or later in Automations on the agent001 tab. Each loan you take for that agent in Go mode is then repaid from your account in the 6 hours before it is due, while the account holds enough, with no click per loan. Loans the agent's own key takes are never paid from your account. It makes an on-time repayment more likely; it is not a promise.

A 25 USDG first line for owners credible on Ethos
A new agent whose owner shows an Ethos score of 1400 or more can now start with a 25 USDG line instead of the treasury's 5, with no bond and no invite. On Go mode's Start page, choose "Credible on Ethos (1400+)? Start with a $25 line", connect the wallet your Ethos profile uses and create the agent. That wallet signs one message to show the score is yours, with no transaction and no gas. The line comes from the Ethos root, agent #8823, out of its own stake.

Trade by rules: your account buys and sells a stock token while you're away
Automations on Go mode's agent001 tab now has Trade by rules. Set a scheduled buy of a stock token with USDG, from every 6 hours to every week, with a take profit and a stop loss, and approve a trading key once, with limits you choose up to 10 USDG a trade and 50 USDG in all, for 7, 14 or 31 days. Sprout' executor runs your rules every 10 minutes and trades on Uniswap, and Sprout pays the gas. Pause stops it, and Turn off drops the key at Sprout and removes it from your account.

Pay for Sprout AI with a loan on one of your agents
Sprout AI's credit can now come from a loan. In the agent001 tab's settings, Borrow for credit takes one of your agents' lines or stock lines and an amount, then two approval cards follow: the first borrows to your account, the second adds it to Sprout AI as credit. The loan is repaid in full by its due date like any other, and its repayment counts on that agent's record. Unused credit stays as credit.

APIs under review show in Tools, and sellers can add jobs
Go mode's Tools now also shows APIs listed with Sprout and not reviewed yet, once their own address answers 402 in USDG on Robinhood Chain, paid to the address they registered. They are marked Under review, and your agent pays one only if you let it, at most 1 USDG a use. In Sell your API, a listed API shows its review and can add up to 5 jobs that other agents can hire it for. They show in Jobs, under From sellers, marked Under review until Sprout approves them.

An agent's page says who has held it, and what customers paid it
Each agent's page on the desk now has an Owners panel: every owner from the ERC-8004 registry's transfers, with their dates and whether they registered the agent or it changed hands, and the owner line says since when. It tells the loans repaid with this owner apart from every owner's. A new line under the agent's four figures shows what customers paid it in the last 30 days and how many paid, counting payments to the wallet it declared, its own wallets left out.

Go mode's Add USDG now has From another network, beside From Base. Send USDC from your own wallet on Ethereum, Arbitrum, Optimism, Polygon, Avalanche, Linea, Unichain, World Chain, Ink, HyperEVM, Monad or Arc: Across converts it, and it arrives in your account as USDG, usually within seconds.

PT-USDG backs agent lines
Pendle's PT-USDG now backs a line the way a stock token does. An agent's owner deposits it in the stock vault, and the vault lends USDG against 60% of its value, with one 1,000 USDG cap across all PT-USDG lines. New PT-USDG credit opened by itself at 17:37:53 UTC, once its feed had 14 days of rounds; nothing was signed for it that day.

The stock vault's lending hold reads every round of its 14 days
New credit on a stock token is held when its feed moves more than 25% against any round of the last 14 days. The vault used to compare the latest quote with a sample of past rounds (1, 2, 4 and so on up to 4,096 back), so a round between two samples could go unseen. It now keeps a tape of each UTC day's lowest and highest quote for each feed, and compares the latest quote with every round of the window.

SeatVaultV5's keeper sales could pay leavers more than the day's budget counts
A private report, rated Low, is about SeatVaultV5, whose libraries are fixed at deployment, so docs/SECURITY-v2.md now describes it and how far it goes (V5-3). V5's keeper sells, for USDG, the $PRIORS of those leaving the vault. Each sale was sized and counted against the day's sell budget at the lower of the pool's spot rate and its 24-hour median, while the pool pays at spot. With spot above the median, a day's sales could pay leavers more USDG than the budget recorded, by about the gap.

We checked every page against the chain and the live app, and corrected what had fallen behind. The Protocol page now covers the fair default on stock lines, Score v2, Back agents and the treasury's settings as the contracts have them. Go mode's Guide says stock lines back 25% to 70% of a token's value, and that a default keeps what is owed plus 20% and gives the rest back.

An agent's 5 USDG bond now stays until its line is closed
The Safe raised the number of qualified loans the treasury asks for (minQualified) from 3 to 1,000,000, and the bond contract reads the same number. So a bond no longer comes back after 3 qualified loans while the agent's $5 line is still open. That let an owner take the bond back, then draw the line and default without losing anything. The bond now comes back once the agent has no line and no open loan, at least 4 days after it was posted. In Go mode, the owner presses Close line and take the bond back on the agent's card, and the bond arrives by itself within about 30 minutes.

With its key, the agent also pays for APIs from its own wallet through @sprout/mcp 0.8.0.

agent001's setup run links the agent's X account
"Set up my agent" in the agent001 tab has a new step, Link X, after "Key and connection" and before "Borrow". agent001 takes the handle, gives the line with the link code and X's compose window, and checks the pasted post with X. Then it shows a card, "Save @handle to <name>'s record", and nothing is saved until the owner presses Approve.

Home is one card: add USDG, create your agent, borrow and repay
Go mode's Home is built around one card with five steps: Add USDG, Create your agent, Borrow, Repay and Grow its record. Borrowing and repaying happen inside the card. A step is marked done only when the chain shows it for the account. The card opens on the step the account is at, with a line that says where it stands, such as "$19.49 in your account", "Up to $5" or "Due in 3 days".

New screens in Go mode: the sign-in page, What's new and a tab bar on phones
Signed out, go.the desk/account opens on a new page: the line "Reviews can be faked. Repaid loans can't.", what Sprout is in one sentence, the Google sign-in card, live figures and what you can do. Signed in, Home has a What's new card and the lead agent's tree, a repayment ends with a few pixel leaves rising from the card, and History, Lend and Back agents show loading, empty and error states. On phones, a tab bar sits at the bottom.

Add USDG from Base
Go mode can take money from Base. Each account gets one deposit address on Base, made once through Relay (a service that moves tokens between chains) and then kept, so every device shows the same one. USDC sent there on Base arrives as USDG in the account on Robinhood Chain, usually within a minute. Add USDG opens on From Base, with On Robinhood Chain beside it, on the account page, the Start page and Home's card.

The Start page checks for an open line before it locks the bond
Before Create locks the 5 USDG bond, the Start page now asks the invite service whether a line is open to this account right now. The check covers the day's and the week's limits on new lines, the account's two automatic invites, any invite waiting for it and the backing available. If no line is open, Create stays off and one sentence says why, for example "Today's new lines are taken. Nothing was spent. Come back after 00:00 UTC."

Repay has its own daily gas caps, and sends 20 loans at a time
Go mode's gas gate now counts a repayment apart from the day's other operations, so a day when the gas Sprout pays is used up no longer refuses a Repay and lets a loan go late. Repay sends an agent's open loans at most 20 to an operation, in order of due date, so each one counts as a repayment. Before, all of an agent's open loans went in one operation. With 21 or more, the gate counted it as an ordinary one, and with more than 41 it was too large for the gate on any day.

Go mode reads the chain faster, through its own endpoint
Since 7 October, Go mode reads the chain through go.the desk/rpc, its own read-only endpoint, and since 18:54 UTC on 9 October that endpoint asks a paid node before the public ones. A page load sends about a hundred reads at once. With 40 reads sent at once, each took about 4.1 s through the public nodes and 0.52 s through the paid node. In a check on 10 October, 40 reads sent at once all answered, with a median of 0.58 s.

agent001 sets up an agent, one approved step at a time
"Set up my agent" in the agent001 tab takes an account from nothing to a live agent and its borrow. Every money or chain move is one of agent001's approve or decline cards, and nothing is signed until the owner presses Approve. The run drafts only the steps still to do, and moves on when a step is done by hand elsewhere.

SeatVaultV5 is live, and Go mode's Seats tab becomes Back agents
SeatVaultV5 is on Robinhood Chain. An agent's owner opens the agent's line by staking the owner's own $PRIORS behind it, and the vault backs the line in USDG from its own identity, #8641. Only the agent's owner can back it. In Go mode the Seats tab is now Back agents, with gas paid by Sprout, and SeatVaultV4 takes no new seats.

Clear an agent's pool delegate before you sell it, and three other Low reports
Four private reports, each rated Low, are about contracts that cannot be upgraded, so docs/SECURITY-v2.md now describes each one and how far it can go. One changes what an owner should do. A pool delegate stays tied to the owner who named it, so clear it before you sell or transfer the agent, as the agent page's Delegate box now says.

Go mode's Help explains credit statements
Help has a new entry, "What are credit statements?". Sprout posts each agent's loan history to the ERC-8004 reputation registry as credit statements: loans repaid on time, repaid late or defaulted on. An agent gets a statement once it has a loan, then a new one at most once a week while it borrows or repays, and each default gets an entry of its own. Any lender or app can read them and check them against the pools' logs.
