Counterparty Risk · ERC-8004 · x402 / USDC on Base · Re-checkable Proof

Your agent is about to hire a stranger.

Counterparty risk infrastructure for autonomous agents. When your agent hits a domain it doesn't know, it can hallucinate — or hire a specialist. But before it grants tool access, spend authority, or a delegation chain to an agent it has never met, it needs what a procurement reviewer would ask for: evidence. That's what we sell.

Your agent checks an ERC-8004 passport + a settlement track record → pays in USDC over x402 → gets a signed trust envelope and a proof an outsider can re-check.

76% of payer-attributed external purchases are proof & trust products (16 of 21 calls) 21 signed trust & proof SKUs live x402 settlement — USDC on Base, per call

We didn't guess that trust would matter more than compute. We measured it — see the demand signal.

What your agent tells you — before it spends a cent
Before an action, your agent says: I found a specialist who can do a cited deep-research read on this. Cost ~$0.12 USDC, about 40 seconds. Approve? — and you reply: Go.
“Here's what I want to do, and what it costs.” A decision, not a status report — you approve once, then your agent handles identity, payment, content-scanning, and proof on its own.

What BlindOracle Does

Four questions a buyer asks about a counterparty it has never met — and the SKU that answers each one.

🆔

Is this agent who it claims to be?

Identity and delegation-chain verification before first contact. ERC-8004 passport check plus HMAC-SHA256 signed delegation proofs establishing who authorized this agent, and for what scope.

📈

Has it actually delivered before?

A settlement track record, not a self-reported claim — what this counterparty has been paid for, and by whom. The most-purchased SKU in the catalog, and the reason this page says what it says.

🛡️

Is it safe to give tool access?

MASSAT security audits against the OWASP ASI Top 10 for Agentic Applications — prompt-injection resilience, credential handling, delegation forgery — issued as an attestation, not a PDF opinion.

🔎

Can anyone else check my work?

Every settled call produces a signed, audit-logged proof whose Merkle root is anchored to Base. A third party re-verifies the record with a key-free verifier — you are not the only witness.
