How this service works
first-funder goes one hop; this walks the funding chain back up to 8 hops to a recognisable origin (a CEX/bridge on-ramp — lower-risk provenance) OR a SANCTIONED address (dirty money, taint by provenance) OR a dead-end of fresh anon EOAs (the sybil/burner-cluster shape). One verdict compliance can refuse on. Best-effort: internal-transfer funding is invisible and ends the walk, never guessed. A CEX origin is a signal, not identity. Not financial advice.
Output
A verdict classifying the wallet's funding origin: either a recognizable CEX or bridge on-ramp (lower-risk), a sanctioned address (high-risk taint), or a dead-end of fresh anonymous EOAs (sybil/burner-cluster pattern). Includes the hop depth reached and the chain path walked, stopping when an internal transfer makes further tracing impossible.
Example use cases
AML check before onboarding
“Before we onboard this user, trace the funding chain of their wallet 0x7a3f9c1e4d8b2a6f0e5c7d9b3a1f4e2c8d6b0a9e up to 8 hops and tell me if there's any sanctioned address in its history or if it looks like a burner cluster.”
DeFi protocol risk screening
“We're about to let wallet 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b participate in our liquidity pool — can you trace its source of funds up to 5 hops and give me a verdict on whether the money looks clean, exchange-originated, or suspicious?”
Investor provenance due diligence
“An investor wants to wire 500k into our fund from wallet 0xdeadbeef1234567890abcdef1234567890abcdef — trace its funding chain back as far as possible and tell me if it originates from a legitimate CEX, a sanctioned entity, or an anonymous cluster of wallets.”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/fund-trace?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a multi-hop provenance verdict rather than a single-hop funding check — especially for compliance workflows where you need to know whether funds ultimately trace back to a sanctioned entity, a legitimate CEX, or an anonymous cluster. Ideal for AML screening, investor due diligence, and DeFi protocol onboarding where a single-hop check would miss layered obfuscation. Not suitable when you need identity-level KYC (a CEX origin is a signal, not a person), or when real-time sub-second latency is critical.
Side effects
- Internal-transfer funding breaks the chain and returns a dead-end verdict without being able to walk further
- Wallet has no on-chain funding history (fresh wallet with no inbound transactions)
- Chain reaches the 8-hop maximum without resolving to a known origin
- Requested wallet address is invalid or malformed
- Rate limiting or payment failure prevents the call from completing
