How this service works
Bind an ERC-8004 registry identity to supplied, independently marked evidence without claiming ownership
Output
Returns a binding confirmation record associating the ERC-8004 registry identity with the supplied evidence, including attestation metadata, provenance markers, and the binding status — all without asserting ownership of the identity.
Example use cases
Regulatory audit trail for DID
“We need to associate our ERC-8004 registry identity with the compliance evidence documents we've already independently marked — bind them together without claiming we own the identity.”
Third-party evidence attestation
“Link this ERC-8004 identity to the evidence bundle our auditor marked independently — I want an association record that doesn't imply ownership on our part.”
Identity evidence anchoring for KYC
“Attach the KYC evidence markers we collected to ERC-8004 identity 0xDEADBEEF in the registry, binding them as associated evidence only, no ownership claim.”
Technical details
Endpoint
POSThttps://phion.systems/v1/paid/trust/erc8004-identity-evidence?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to formally associate an ERC-8004 registry identity with externally or independently marked evidence without making an ownership claim. It is distinct from identity ownership registration or verification — choose it when the goal is evidence linkage and attestation rather than identity claiming or resolution. Prefer it over generic blockchain attestation services when you specifically work within the ERC-8004 standard.
Side effects
- Invalid or unresolvable ERC-8004 identity returns a resolution error
- Malformed or missing evidence markers cause a validation rejection
- Duplicate binding attempts for the same identity-evidence pair may return a conflict or idempotency error
- Insufficient evidence marking or independent attestation signals cause binding refusal
- Payment failure (x402 protocol) prevents endpoint invocation
