How this service works
TraceFast risk data: is this Ethereum address on a token issuer's on-chain blacklist? One row per issuer contract that ever listed it (USDC, USDT, any token with a blacklist) — listed now or not, the issuer's weight (`authorityTier`), first and latest events — plus the issuers that froze or destroyed its funds. Read from the issuers' own contracts, not from sanctions lists. Path address: `0x`-prefixed. Docs: https://docs.tracefast.xyz/api/risk-blacklist-status.md
Output
Returns one row per issuer contract that has ever blacklisted the queried address, including the issuer's authorityTier weight, whether the address is currently listed, timestamps of the first and most recent blacklist events, the number of listing/delisting transitions, and a separate set of facts about issuers that have taken enforcement actions (frozen funds or destroyed them).
Example use cases
Compliance screening before DeFi interaction
“Before my protocol onboards this wallet, I need to know if 0x4838B106FCe9647Bdf1E7877BF73cE8B0BAD5f97 has ever been blacklisted by any on-chain issuer — pull the issuer list, their authority tiers, and whether any have actually frozen or destroyed funds tied to it.”
Stablecoin issuer enforcement audit
“I'm auditing whether Tether or Circle have ever enforced against 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — show me every issuer that blacklisted this address, the current status, and any freeze or destruction actions recorded on-chain.”
Risk scoring for a transaction counterparty
“I need to assess the blacklist risk of wallet 0x95222290DD7278Aa3Ddd389Cc1E1d165CC4BAfe5 on Ethereum — which issuers have ever listed it, how authoritative are they based on their tier, and how many times has it toggled on and off the blacklists?”
Technical details
Endpoint
GEThttps://mpp.tracefast.xyz/api/v1/chains/1/risk/blacklists/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, deduplicated blacklist summary per issuer for an Ethereum address, including historical listing status and enforcement severity — ideal for compliance screening, risk scoring, and counterparty due diligence. Prefer this over the raw blacklist events endpoint (which returns individual events) when you want pre-aggregated issuer-level statistics including transition counts and authority tiers.
Side effects
- Invalid or malformed Ethereum address (not 0x-prefixed or wrong length) returns an error
- Address with no blacklist history returns an empty result set
- Network or RPC latency may cause slow responses for complex address histories
- Payment failure or insufficient USDC balance prevents the x402-gated response
- Chain ID 1 only — requests for other chains will not return data
