chainpeek (Tanod) address-poisoning check before a token transfer
chainpeek (Tanod) address-poisoning check before a token transfer: is the recipient a lookalike (same first and last 4 hex characters) of an address in the sender's history or contacts? Use when an agent is about to send USDC or a token and must check the recipient is not an address-poisoning lookalike.
