Mainnet Contract Addresses

All Lightchain AI Mainnet contracts and service accounts. Always verify addresses against this page (or the on-chain registry) before signing transactions.

[!NOTE] The five upgradeable protocol contracts (AIConfig, JobRegistry, WorkerRegistry, SessionManager, FeePool) are owned by the protocol owner EOA (0x8a35E00eff6f3bf125aE5011cc7C603E18B8D616); the Treasury is owned by the Timelock. The five are pending handover to a multisig and ultimately the Timelock-controlled Governor. Verify the current owner on-chain before relying on any privileged action.

Protocol Contracts

Most protocol logic lives behind upgradeable proxies. Always interact with the proxy address; the implementation is exposed for source verification only.

Governance

Contract	Address
TimelockController	`0xc783376c8237E8f1ed17d825CE7CBB4c22e3cAE5`
LightChainGovernor (proxy)	`0xD216A0c0050EdC3a9E0449EcFDf178A1652b4b68`
LightChainGovernor (impl)	`0x68ab5a4F64140b1b6680463Cc92204107B35BBa4`

Treasury & Fees

Contract	Address
Treasury (proxy)	`0x786eDe8C42Ca54E54c9dCECa9b30052CF4743389`
Treasury (impl)	`0xCC56dc931E9DaEfa19540cBdbDE67BF4796BcdC5`
FeePool (genesis predeploy)	`0x0000000000000000000000000000000000001004`
FeePool (impl)	`0x45ef17a79e71f2e07C0D2F60DF214bBAfdF0b60e`

AI Protocol

Contract	Address
AIConfig (proxy)	`0x24D11533C354092ed6E18b964257819cE78Ce77D`
AIConfig (impl)	`0x8D522807dF6000E9995a69cBDC5d8c3A0C484007`
JobRegistry (proxy)	`0xfB15F90298e4CcD7106E76fFB5e520315cC42B0b`
JobRegistry (impl)	`0xe70329aCfAb8156997d174aFeC02a85301FCecF5`
SessionManager	`0xfFFCed75eF4Cdae0Cc33A27Bb46531B957a9f4e7` — resolve with `AIConfig.getSessionManagerAddress()`
WorkerRegistry (genesis predeploy)	`0x0000000000000000000000000000000000001002`
WorkerRegistry (impl)	`0x32AbA9E4d0E796E519719DC3d61fcED52d08c20a`

Native Voting

Contract	Address
NativeVotes (genesis predeploy)	`0x0000000000000000000000000000000000001001`

[!TIP] Genesis predeploy addresses (0x…0001001, 0x…0001002, 0x…0001004) are part of the chain's genesis state and are stable across upgrades.

Service EOAs

The following externally-owned accounts run protocol services on mainnet. They are intentionally separate from the deployer EOA and can be observed on-chain.

Service	Address
Dispatcher (retired 13 Oct 2026)	`0x93953f40A472E65cD0212a2DA38dD1337854256F`
Worker-gateway	`0x46737082Ac84e64f936cDDBa28F5Cd5E71329E62`
Disputer	`0xED60d14E586219D7c984bDf0AA720a6Bd96B5F73`

The dispatcher no longer runs: workers claim sessions on-chain (dispatcher-free mode). AIConfig still holds its address (getDispatcherAddress()), and only the legacy dispatcher path checks its signature: JobRegistry.createSession, and session key updates while sortition is off.

Whitelisted Models

All models below are registered on AIConfig and whitelisted on WorkerRegistry. The modelId is the keccak256 hash of the model name, which is also the Ollama tag a worker runs. Values as of 2026-09-13.
