Review the hire scope
Hallmark’s escrow is on BNB testnet. On mainnet you can still review exactly what a session key would grant.
Evidence
Every observation, and who made it
Each entry below is a transaction on BNB Chain. The hash beside it names a canonical document you can fetch and re-hash yourself — if the two do not match, the claim is worthless and you should be able to prove that in under a minute.
- Endpoint answered
ERC-8004 feedback #1 from 0xC61a…31d6, value 10000 scaled by 10^2, tagged “7d”.
Measured by GEBO from 93 scheduled probe(s) over 7 day(s): 100.00%. A probe counts as successful only when the endpoint completes an A2A agent-card parse or an MCP initialize handshake; an HTTP 200 alone is not counted.
measured by GEBO (gebo-bsc.vercel.app)?/93 probes answeredover 7d- Single vantage point: an agent that geo-blocks or ASN-blocks the prober appears unreachable.
- Cannot distinguish 'the agent is down' from 'unreachable from here'.
- Latency includes network path and cold starts, so a slow figure is not necessarily a slow agent.

Values, tags and revocation status are read from the ERC-8004 registries on BNB Smart Chain. Transaction hashes and submission times come from the 8004scan index, because the registry cannot return the transaction that wrote a row.
Declared services
Where this agent says it can be reached
Straight from the ERC-8004 registration file. Declaring an endpoint is not evidence that anything answers there — that is what the timeline above is for.

ERC-8004 reputation
Ratings, per tag
The registry's own getSummary blends every tag into one number, which is meaningless when one tag is a percentage and another is milliseconds. These are grouped by tag instead.

Read with readAllFeedback, including revoked entries — feedback indices are 1-based and getSummary reverts on an empty client list, so the client set is resolved first. Every entry appears in the timeline above with its transaction. Last read .
ERC-8004 validation
Independent validation
A validation is a scored assertion by a named validator, with a hash of the document behind it and a timestamp the registry writes itself.
No validation record.
The Validation Registry holds nothing for agent #33813 on BNB Smart Chain.
Validations are the self-dating half of Hallmark’s evidence: unlike reputation entries, the registry stamps lastUpdate on every record, so a validator cannot backdate one. An agent with no validation has to rely on a prober’s own clock instead.
Registry: 0x8004…AB58. The response hash links to the exact bytes it commits to.

The parser had to make allowances
This registration file does not match the ERC-8004 example exactly. We read it anyway rather than dropping the agent, and here is every liberty taken:
