How this service works
Onchain Collateral Attestation analyses only the evidence supplied by the caller. It does not claim to query a chain, identify a legal status or replace an independent audit. Missing signals lower confidence and are listed explicitly; every classification includes the exact thresholds used.
Output
Returns a confidence-scored collateral attestation classification for the supplied subject, including the exact thresholds applied to each metric, a list of any missing or omitted signals that reduced confidence, and the classification verdict — without making any independent onchain queries.
Example use cases
Stablecoin backing check before deployment
“I'm about to deploy liquidity into a stablecoin protocol at 0xDeadBeef...5678. I have evidence that the collateral gap is 1.8%, the proof is 6 hours old, and there's no issuer mismatch. Can you run a collateral attestation and tell me the confidence score and whether any required signals are missing?”
DAO governance collateral proposal review
“Our DAO has a proposal to add a new collateral asset — the subject is 'USDY-proposal-42'. I have a collateral gap of 0.5%, proof age of 48 hours, and issuer mismatch is true. Run a strict-mode collateral attestation and list any missing signals and the exact thresholds used for the classification.”
Stale proof risk flagging for lending protocol
“I want to check whether the collateral evidence for lending protocol 0xLend...9900 is still valid — the proof is 72 hours old, collateral gap is 4.5%, and there's no issuer mismatch. Give me an attestation with confidence score and flag if the proof age is over the acceptable threshold.”
Technical details
Endpoint
POSThttps://stable.halowerk.com/v1/onchain-collateral-attestation?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, auditable, confidence-scored attestation of collateral adequacy based on evidence you already hold — particularly when you need explicit threshold disclosure and missing-signal reporting for compliance, governance, or risk documentation purposes. It is not a live onchain query tool; prefer it when your agent has already gathered collateral metrics and needs a formal classification layer with traceable thresholds.
Side effects
- minItems violation: evidence array is empty — request rejected
- strict mode enabled but one or more documented metrics absent — request rejected with list of missing fields
- metric value out of expected range — may lower confidence or trigger explicit warning
- subject field missing or empty — validation error
- evidence array exceeds 50 items — request rejected
- malformed ISO-8601 timestamp — field rejected or ignored
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| strict | boolean | Reject unless all documented metrics are supplied. |
| context | object | Optional non-secret labels returned unchanged for correlation. |
| subject | string | Address, transaction, protocol, asset, proposal or other subject being assessed. |
| evidence | array | Caller-supplied observations. Repeated metrics form a time series; the newest timestamp is assessed. |
