AgentRegistry (MRC-58)

Two deployed versions: v1 (free) and v2 (1 MOR paid). Both implement the MRC-58 Agent Registry standard.

Source: registry-contracts/contracts/agent/

Deployments

Variant	Arbitrum One	Base mainnet
v1 (free)	0xCC258a…454F	0xd4D014…5ca4
v2 (1 MOR fee)	0x5563Be…3625B	0x191630…2697

v1 vs v2

	v1	v2
Registration fee	0	1 MOR
Fee recipient	n/a	Hypnex treasury
Spam resistance	low	high
Use case	hobby agents	production agents

Both are usable simultaneously. The hypnex-registry SDK defaults to v2 since 0.3.0.

Functions (both versions)

register

function register(bytes32 agentId, string calldata manifestUri) external;

v2 additionally pulls 1 MOR via transferFrom. The fee transfer is atomic with the registration — if approval fails, the whole tx reverts.

agents(bytes32 agentId)

function agents(bytes32 agentId) external view returns (AgentRecord memory);

Returns { owner, manifestUri, registeredAt }.

updateManifest

function updateManifest(bytes32 agentId, string calldata newUri) external;

Owner-only. Manifest URI is mutable; the agentId itself is permanently bound to the registering address.

Events

event AgentRegistered(bytes32 indexed agentId, address indexed owner);
event ManifestUpdated(bytes32 indexed agentId, string newUri);

SDK
