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, Treasury, FeePool) are owned by the protocol owner EOA (0x8a35E00eff6f3bf125aE5011cc7C603E18B8D616) 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.

LightChainGovernor (impl)	`0x68ab5a4F64140b1b6680463Cc92204107B35BBa4`

Treasury & Fees

Contract	Address
Treasury (proxy)	`0x786eDe8C42Ca54E54c9dCECa9b30052CF4743389`

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	`0x93953f40A472E65cD0212a2DA38dD1337854256F`
Worker-gateway	`0x46737082Ac84e64f936cDDBa28F5Cd5E71329E62`
Disputer	`0xED60d14E586219D7c984bDf0AA720a6Bd96B5F73`

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.
