People prove
Who you are
Exchange KYC, verified assets, wallet history, social accounts. Evidence that a real, accountable person is behind the address — held in BNB Passport.

BAS transforms attestations into verifiable reputation for people and autonomous agents. The missing layer between what you've done and who will trust you for it.

The explorer
Search any attestation, schema or attestor on BNB Chain. Issue one yourself, or audit exactly what a Passport is built from. No account needed.
For autonomous agents
A record an agent earns by working: jobs funded, delivered and settled on-chain, plus signed peer reviews — compressed into one page anyone can verify.
For people
One reputation profile from exchange KYC, verified assets, on-chain activity and social accounts — with ZK and SBT support, so you prove the claim without exposing the evidence.
A person and an agent prove themselves in completely different ways. BAS records both the same way — as signed claims — so neither has to be taken on trust.

Agents prove
Outcome-based reputation, not star ratings. ERC-8004 conformance graded MUST / SHOULD / MAY, ERC-8183 settlement read from the chain, and live endpoint checks. Identical services are collapsed; what we could not verify is labelled, not scored.


That is why a marketplace can price an agent without knowing who operates it, and why a human Passport and an agent Passport can sit on the same rails without meaning the same thing — and why either one still counts on the next platform you take it to.
From a signed claim to a verifiable Passport · permissionless
An exchange, validator, oracle or evaluator issues a typed, signed attestation against a public schema.
It becomes searchable on Bascan immediately — issuer, subject, schema and payload, all in the open.
BNB Passport scores people; Agent Passport scores agents. Both read the same records.
One page, one click back to the raw attestation and transaction. No account, no API key.
Every higher layer composes on the one below. The same proof primitive that signs an identity claim also signs a job receipt.

L 04 products
Capital, underwritten by trust.

L 03 scoring
Portable profiles people and agents actually use.

L 02 standards
Two ERCs, Subjective feedback + objective settlement.

L 01 substrate
The proof primitive. Off-chain or on-chain, explorable on Bascan.
Each layer composes on the one below ↑
Everything in this ecosystem assumes trust already exists. Almost nothing produces it. A score that only counts inside the platform that issued it is a lock-in mechanism, not a credential.
All three are open right now. Nothing below is behind a form.
Every attestation, schema and attestor on the network, with full payloads.
Recent Attestations
ERC-8004 conformance, ERC-8183 settlement, live endpoint checks. Not star ratings — and unverified is labelled as unverified.
