Data sources
Every figure in a report traces back to one of these. Each report lists which of them answered, when, and with which list version.
When a source is unreachable
A screening never fails outright because one upstream is down. The affected check is recorded as unavailable rather than as a negative result, the report is marked degraded, and the provenance block at the foot of the report shows which source did not answer.
This distinction matters: “no match on a list we could read” and “we could not read the list” are different statements, and only the first one supports a decision to proceed.
Optional upgrades
The service runs entirely on the keyless sources above. Supplying an indexer API key deepens counterparty resolution and lifts the per-address transfer cap; it does not change the sanctions or register sources, which are free to read in every case.
- Etherscan V2 - one key covers Ethereum, BNB Chain, Polygon, Arbitrum and Base.
- A multichain data provider - richer labels and token-level flow.
- A WalletConnect project id - mobile and hardware wallet verification.
