Digital Identity Standards for Tokenization
Digital identity standards — from W3C Verifiable Credentials to ONCHAINID and Circle's Verite — provide the KYC infrastructure that makes programmable compliance possible in tokenized asset markets.
ERC-3643 — The Institutional Security Token Standard
ERC-3643 (formerly the T-REX protocol) is the most widely adopted Ethereum token standard for tokenized securities, embedding investor identity verification, transfer restrictions, and regulatory compliance directly into the token's smart contract logic.
On-Chain KYC/AML
On-chain KYC/AML systems store verified investor identity claims on a blockchain, enabling smart contracts to automatically check investor eligibility at the point of token transfer — eliminating the need for centralized compliance gatekeepers on every transaction.
