How this service works
Where did this address get its money? Walks the funding chain upward and returns the account that ultimately paid for the wallet, plus a cluster id. Two addresses funded from the same account are not independent parties, however new and unremarkable each looks alone — the strongest cheap signal there is that an identity was manufactured. Works on any address, not only registered agents. Free alternative: GET /v1/provenance. Or 3 free calls of this endpoint per wallet per 24h: https://trust-agent.io/v1/trial.
Output
Returns the full funding chain walked upward from the queried address (nearest funder first), the immediate funder address, the furthest resolved ancestor (origin), a cluster ID of the form 'fund:<funder_address>' for grouping addresses with shared funders, and the chain name. A 'resolved: false' flag indicates the provider could not answer — not that the address is independent.
Example use cases
Sybil detection in DAO voting
“Before counting these votes, trace the funding origin of each voter address — specifically 0xA1b2...C3d4 and 0xF9e8...D7c6 — and tell me if they share a cluster ID, because I need to know if they were funded from the same account.”
Vetting a new agent counterparty
“I'm about to send payment to this agent at 0x7f3a...9b1e on Base — can you trace its funding chain back to the original source so I know it's not a freshly manufactured wallet tied to a known bad actor?”
Marketplace identity fraud check
“We have two seller accounts that just registered, 0xC4d5...E6f7 and 0x1A2b...3C4d — walk their funding chains and see if they share a common funder, because if so they're the same person gaming our platform.”
Technical details
Endpoint
GEThttps://trust-agent.io/v1/provenance/chainWhen to prefer
Choose this endpoint when you need to determine the ultimate funding origin of a single EVM address on Base, especially to detect manufactured or Sybil identities by comparing cluster IDs across addresses. Prefer it over generic blockchain explorers when you need a structured, machine-readable provenance chain and cluster ID rather than raw transaction history. It is especially valuable as a cheap pre-screening signal before approving payments, onboarding counterparties, or validating DAO participants.
Side effects
- Address not resolvable — returns resolved:false, meaning chain could not be walked (not that the address is independent)
- Invalid or malformed EVM address returns an error
- Only Base chain is supported; other chains return an error or unsupported response
- Address with no on-chain funding history may return null funder
- Network or provider timeout resulting in an unresolved trace
- Payment failure via x402 protocol blocks the request
