A-identity

A-Identity is the identity and reputation oracle for the agent economy. Agents call us before they pay a counterparty and get one answer back: is this safe?

Every call reads live on-chain data. ERC-8004 identity and KYA, a deterministic 0 to 1000 reputation built from real settlements, and a pre-transaction ALLOW, WARN, or DENY.

We check both sides of a deal, so we catch agents that trade with themselves to fake a score.

Live on OKX.AI as A2MCP Agent #6271. Six services sold per call over x402 on X Layer mainnet, one of them free.

120 real settlements to date, each verifiable on OKLink.

We built and shipped the A-Identity Trust Oracle end to end during the hackathon, and listed it on OKX.AI as A2MCP Agent #6271 on X Layer mainnet (eip155:196).

Six pay-per-call x402 services went live: verify_agent ($0.001), reputation_score ($0.002), risk_check ($0.005), counterparty_check ($0.008) and agent_passport ($0.01), plus a free trust_preview as an on-ramp. counterparty_check reads both agents in a deal and flags same-operator self-dealing. KYA can be revoked, which turns a later risk_check into a real DENY.

The engine earns real on-chain revenue: 120 x402 settlements in USD₮0, each independently verifiable on OKLink and listed at our public /proof endpoint.

Under the hood: a deterministic 0 to 1000 reputation scorer covered by 163 unit tests, live ERC-8004 IdentityRegistry and ValidationRegistry reads via viem, a public /methodology page with the exact reproducible formula, Sybil wash-trading detection, and multichain identity reads that also resolve OKX.AI's own agents from their registry. The showcase agent, Meridian, is registered on ERC-8004 and KYA verified.

We also shipped a public Trust Explorer and a one-click claim flow on the landing, and produced the demo video, the OKX.AI listing and this submission.

Bootstrapped, pre-seed. We have not raised external funding.

The product already earns real on-chain revenue on X Layer mainnet through pay-per-call x402 services, 120 settled payments so far. We are open to conversations with ecosystem funds and grant programs to extend the trust oracle across more chains.
