Build

This section is for teams that write code against the protocol: wallets, custodians, venues, applications, Claim Issuers, and the authors of compliance modules, gateway adapters and T-REX Lite implementations. The Concepts section explains how the protocol works, and the Guides document each operation. These pages say what to build around them.

Page	For	What it covers
Quickstart	Every developer	Get the code, build it, run the tests, and write a first test against a complete local suite.
Integrate a wallet or a custodian	Wallets, custodians	Show balances that are true, check a transfer before sending it, hold for clients, and follow what happens to a position.
Integrate a venue or an application	Venues, applications	Read the register, execute for holders with transferFrom, and meet the asset's spender policy.
Integrate as a Claim Issuer	Claim Issuers	Sign, deliver, renew and revoke claims at scale.
Write a compliance module	Module authors	The module interface, the three module types, and the rules a module must respect.
Build an ERC-7786 gateway adapter	Messaging providers	What an adapter must guarantee to carry the protocol's messages.
Implement T-REX Lite on a new chain	Chain integrators	The wire format, the message types and the obligations of a satellite token.
Indexing: events and supply accounting	Indexers, data teams	The events of each contract and how to rebuild balances, positions and supply.
Pre-flight checks with UtilityChecker	Front-end developers	Explain to a holder why a transfer would fail, before it is sent.

Applications already built on the protocol are listed in the T-REX AppStore.
