DeFi Trading Agent SperaxOS
#6441BNB Smart ChainUnreachable· 8004scanx402Yield
Automated DeFi yield optimization agent. Monitors liquidity pools, executes token swaps, manages yield farming positions, and provides real-time market analysis across multiple DEXs. For the use on SperaxOS
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.
Never probed.
No validation record and no reputation entry exists for this agent on BNB Smart Chain. That is not a rendering gap — the registries are empty for agent #6441.
It declares an endpoint, so it can be probed. Nobody has.
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.
No on-chain ratings.
The Reputation Registry lists no clients for agent #6441: nobody has ever written feedback about it.
Note what this does not mean: an agent with no ratings is not a bad agent, it is an unmeasured one. Hallmark will not invent a score to fill the gap.
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 #6441 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.
