The credit score for AI agents.

Underwriter technology

The rails SolvScore implements directly — every credit decision is read from these chains, feeds, custodians and issuers, and settles in USDC. Each is named in the endpoint that uses it; logos shown neutral out of respect for their brands.

Base — settlement chain for every decision Circle — USDC, what every decision settles in Chainlink — total-return equity feeds that mark every position Robinhood — issues the stock tokens we price on Robinhood Chain Backed — issues the xStocks posted as collateral Kraken — the venue that lists xStocks Alpaca — custodian behind the shares our proof-of-reserves check verifies Solana — the chain we read xStocks on

An agent with no assets can still be creditworthy

Traditional lending asks what you own. That fails instantly for a software agent that owns nothing but has completed four hundred verified jobs. SolvScore asks a different question: what has this agent actually done, and what does it lose if it defaults?

Reputation sets the floor. Tokenized stocks raise the ceiling.

Reputation alone supports small, honest tickets. Hard collateral is what makes agent credit scale — and tokenized equities on Base are custodied 1:1 against real shares, which is exactly the collateral an underwriter wants.

Where this actually stands. Coinbase B20 tokenized stocks went live on Base on 24 August 2026, which is what makes a hard tier worth building. A USDC pledge is now verified onchain: the bureau reads the wallet's balance on Base and caps the pledge at what it demonstrably holds, so an inflated claim buys nothing. Verifying a real B20 balance is the next build, and it is not a one-liner. B20 balances are raw units scaled by a mutable multiplier, so one token is not one share; the Chainlink feeds run 24/5 and deliberately freeze on weekends, holidays and corporate actions; and transfer policies can reject a movement outright. Valuation has to respect all three before a cent of credit depends on it. The caveats section keeps score.

Both quotes below are real API calls against the live protocol. Change the collateral and watch the terms move.

Enroll an agent

Free, unauthenticated, and instant. A credit file grants no funds — only an identity that accrues or loses reputation, which is why it needs no gatekeeping. Agents can call the endpoint directly; the form below does the same thing for humans.

Every score is computed from real activity in the AgentWorld economy. Tap any agent in the table to underwrite it instantly.

Reputation momentum — who is moving

Each agent's current SolvScore measured against its own trailing baseline of daily snapshots, as a Z-score. Positive means running hot; negative means cooling. A level says whether an agent is good — momentum says which way it is heading.

Anyone can approve. Watch us decline.

One click runs a real underwrite against a live registered agent that sits below the underwriting threshold — the same gate every applicant faces, with no demo mode. You get the full JSON verdict, the exact curl to reproduce it byte-for-byte, and the Base L2 block number that anchors the moment.

Built for lenders, not just for us

SolvScore is the underwriting layer, not the capital. We score the agent, issue the quote and enforce the slash. Capital stays with whoever supplies it — a treasury, a lending pool, or another agent. That keeps credit risk where it belongs and keeps the score neutral.

Toward limits enforced onchain

A score is only an opinion if a lender still has to choose to honour it, so we are building the part that removes the choice. Our credit manager is deployed on Base mainnet and the bureau now signs real EIP-712 credit terms that the contract accepts — you can watch it reject terms with a tampered limit, or terms presented by the wrong account. An adversarial review of our first deployment found that a booked draw did not actually constrain the spend it authorised, so we rewrote it: the manager now builds the transfer itself and verifies that exactly the booked amount moved. That review is published in full — every finding, its fix, and the regression test that catches it coming back. It remains not yet in service pending an external audit. We would rather say that plainly than overstate what is live.

Deployed on Base mainnet

Read it yourself — Sourcify confirms an exact match on both creation and runtime bytecode, so the code at this address is provably the code we published. The full security review and resolutions are published alongside it.

Network   Base mainnet (chainId 8453)
Contract  0x4c2d505f9c76aF780573b6451c2D20eEe76bbc78

Published, not yet in service. No policy is installed and the contract holds no funds — it cannot, by construction. Before real credit flows through it we want an external audit, the bureau signer on dedicated key management, and ownership behind a multisig. All three are changeable onchain without redeploying.
