Glossary

The terms these docs use, each with one definition. Names in code font are names of the code.

Term	Definition
Access manager	The contract that decides who can call each restricted function. Each suite has one, a TREXAccessManager, and the network has one for its shared contracts
Agent	An account that holds an agent role on an asset. A Token Agent acts on positions: mint, burn, freeze, forced transfer, recovery, pause. A Registry Agent maintains registrations
Asset	A financial instrument recorded on the register by a token suite
Available balance	For a satellite wallet: its bridged position less what open validations reserve. Token.availableOf
Beacon	The contract a proxy reads its implementation from. Moving a beacon upgrades every proxy that points at it
Bridged position	The part of a holder's position that is active on a satellite. The register records it per satellite wallet
Burn proof	The message a satellite sends when it burned tokens for a recall
Chain key	The bytes32 identifier of a chain: the hash of its ERC-7930 address with an empty account
Claim	A statement about an identity, signed by a Claim Issuer and stored on the identity
Claim Issuer	A party that verifies participants off-chain and attests the result as claims. It has an ONCHAINID of type CLAIM_ISSUER
Claim topic	A number that names the fact a claim attests. An asset lists the topics it requires
Compliance	The second gate of a movement: whether this movement is allowed now, under the rules of the asset. Answered by ModularCompliance
Compliance module	A contract that implements one rule of an asset. Its type is RULE, SPENDER or TRACKER
Compliance Owner	The holder of the OWNER role on an asset: it binds modules and sets their parameters
Delegation-out	The movement that makes part of a position active on a satellite
Domain	A number that scopes the roles of one asset inside an access manager
Eligibility	The first gate of a movement: whether an identity may hold the asset. Answered by TREXRegistry.isVerified
Forced transfer	A transfer ordered by a Token Agent without the holder's signature
Free balance	The balance of an address less its frozen tokens: what it can send. Token.freeBalanceOf
Frozen	An address that can neither send nor receive, or an amount that cannot be sent
Gateway	A contract that carries messages between chains behind the ERC-7786 interface
Golden copy	The authoritative record of an asset and of every identity, held on the reference chain
Guardian	A signer that an Identity Owner names to recover its identity
Identity	An ONCHAINID
Identity Owner	The party that controls an ONCHAINID through its MANAGEMENT keys
Identity type	The category of an ONCHAINID, recorded once by the factory: ASSET, INDIVIDUAL, CORPORATE, IOT, CLAIM_ISSUER, SMART_CONTRACT, PUBLIC_AUTHORITY, AI_AGENT
In transit	An amount burned on one satellite whose mint on another satellite is not reported
Interoperable address	An address with its chain, in the ERC-7930 format. The protocol uses the canonical binary form
Investor	A holder or prospective holder of an asset
Issuer	The legal entity that brings an asset onto the register and governs its token suite
Key	A signer registered on an ONCHAINID, with one or more purposes: MANAGEMENT, ACTION, CLAIM_SIGNER, ENCRYPTION, CLAIM_ADDER, PROPOSER
Late reconciliation	A settlement that arrives after its validation was discarded. It is applied and flagged
Network governance	The body that holds the platform roles: versions, trusted gateways, identity types, reputation
ONCHAINID	The identity of a participant or of an asset: a smart account that holds keys and claims, can hold tokens, and has wallets linked to it
Peer	The contract that represents an asset on another chain: T-REX Lite on a satellite, the token on the reference chain
Platform	The service that prepares, checks and relays operations for an Issuer, an Investor or another actor
Position	What an identity owns of an asset, over all its addresses and all chains. ModularCompliance.positionOf
Recall	The movement that brings a position back from a satellite to the reference chain
Reconciliation window	The time after the expiry of a validation during which its settlement is still expected
Reference chain	The chain that holds the golden copy and runs the full protocol. Also called the T-REX Ledger
Register	The record of who owns an asset, by identity. The token and its compliance on the reference chain
Registration	The binding of an address to an identity for one asset, written by a Registry Agent
Reputation	A score per Claim Issuer, set by Network governance, that gates adding claims without a key grant
Reservation	The amount of a satellite wallet promised to an open validation
Route	The gateway an asset uses for one satellite
Satellite chain	Any chain other than the reference chain on which an asset is made available
Settlement notification	The message a satellite sends after it executed a validation
Spender policy	The rules of an asset about which third parties may execute transferFrom for holders
Standing	A Claim Issuer has standing when its identity is of type CLAIM_ISSUER and its reputation reaches the claim-add threshold
T-REX AppStore	The directory of the applications built on the protocol
T-REX Ledger	The reference chain
T-REX Lite	The token that represents an asset on a satellite. It executes only what the reference chain authorized
T-REX Network	The protocol, its reference chain, the satellites connected to it and the AppStore
Token suite	The contracts of one asset: token, registry, identity storage, compliance and access manager
Trusted issuer	A Claim Issuer that an asset accepts for given claim topics
Validation	The authorization, issued on the reference chain, of one transfer on a satellite: parties, range of amounts, expiry
Validation Keeper	The role that discards expired validations and resolves stuck ones, run by the T-REX Network
Validity window	The time a validation can be executed on a satellite
Venue or application	A contract through which an asset is traded or used. It takes part under its own ONCHAINID
Wallet	An address linked to an ONCHAINID: an externally owned account, a smart-contract wallet, or an address on another chain
