Address Trust
by Address Trust in Security & trust
๐ The 'who am I dealing with?' check for agents. Reads Coinbase's ONCHAIN verification (an EAS attestation by verifications.coinbase.eth) โ meaning the address is tied to a KYC'd Coinbase account, the strongest sybil-resistance signal on Base โ plus the address's Basename. Returns a verified/named/anonymous verdict + trust score. Pair with sign-guard/spend-audit for a full pre-transaction gate. Identity is a signal, not proof of honesty.
