What is ERC-3643?

ERC-3643 (also known as T-REX) is a regulated token standard on Ethereum designed specifically for security tokens and real-world assets. Unlike standard ERC-20 tokens that allow unrestricted transfers, ERC-3643 enforces compliance at the smart contract level through a system of on-chain registries. Every transfer is checked against identity registries and compliance contracts before execution. If the recipient is not verified and whitelisted, the transfer is rejected.

What ERC-3643 Enforces

Identity verification before token receipt
Compliance checks on every transfer
Whitelisted-only token holding
Trusted issuer validation
Claim topic requirements

What ERC-3643 Prevents

Unverified wallets receiving tokens
Transfers to non-compliant addresses
Unauthorized identity claims
Transfers exceeding holding limits
Transfers violating geographic restrictions

Compliance Framework

Identity Verification (KYC)

All security token holders must complete identity verification before their wallet address is added to the Identity Registry. This is enforced at the smart contract level — unverified wallets cannot receive or transfer ERC-3643 tokens.

Compliance Enforcement

The Compliance Contract checks every transfer against predefined rules including holding limits, geographic restrictions, investor qualification requirements, and lock-up periods. Non-compliant transfers are rejected by the smart contract.

Whitelisting & Transfer Restrictions

Only whitelisted wallet addresses can hold security tokens. The Identity Registry maintains the whitelist, and the token contract checks it before every transfer.

Trusted Issuer Framework

The Trusted Issuers Registry defines which identity verification providers are accepted by the system. Claims from unauthorized issuers are rejected, ensuring only verified and trusted identity attestations are used.

Wallet Verification

ERC-3643 tokens require wallet verification before transfers can occur. Every wallet that holds or receives a security token must be verified through the Identity Registry.

KYC/AML Compliance

All token holders are verified through Know Your Customer and Anti-Money Laundering procedures

Transfer Restrictions

Tokens can only be transferred between whitelisted, verified wallets

On-Chain Proof

All verification records are stored on the Ethereum blockchain and publicly auditable

Why This Matters

The Maya ecosystem uses ERC-3643 to bring institutional-grade compliance to blockchain. Unlike standard tokens that can be freely transferred to any wallet, ERC-3643 tokens enforce regulatory requirements at the protocol level. This means compliance is not optional — it is built into the smart contract itself. Every transfer, every holder, and every transaction is subject to on-chain verification. This is the same standard used by regulated financial institutions for tokenized securities.
