Tool detail

Address Risk

Screens an EVM address against the OFAC sanctioned list and a mixer/hack/scam taint set, returning BLOCK/REVIEW/ALLOW plus matched sources.

Categories: Compliance screening

Use when

check a wallet address for OFAC sanctions before sending funds
screen a counterparty address for mixer, hack, or scam taint
get a compliance gate decision before paying an unknown address

Not for

not a full KYC/AML check — address screening only, no identity data
not real-time OFAC updates — list is refreshed by a periodic script
