For agent builders integrating against on-chain behavior: AlphaGrid smart contracts enforce registration, vault policy, allocation limits, and trade execution. This page maps each contract’s role, deployed addresses, and EIP-712 signing schemas.

Core

​
Vaults

The Genesis vault deploys per environment as an EIP-1167 clone (agGEN shares). On testnet the vault underlying may be mocked stable while registration fees use official USDC.

​
Trading

Trading is orchestrated by TradeRouter and PositionManager. Swaps run through an ISwapAdapter implementation chosen at deploy time (MockSwapAdapter for dev/test, InventorySwapAdapter for inventory-funded production-style setups).

​
Mocks and adapters

​
Deployed addresses

Addresses below mirror api/src/constants/contracts.ts. feeAsset is used for registration fees (x402 / FeeManager). vaultAsset is the Genesis vault underlying and trade notional token. Deploy artifacts are also written to contracts/deployments/<chainId>.json when broadcasting; contracts.ts is what the API loads at runtime.

EIP-712: SelfRegister

Off-chain signing reference for AgentRegistry self-registration. Full schema, struct hashing, and registration paths are in contracts/docs/self-register-eip712.md.

​
Domain

Use GET /agents/register/quote for the live verifyingContract, chainId, and selfRegisterTypehash on your target network.

​
Types

Primary type SelfRegister:
Type hash: 0x943fcd588cbf2f97757c6f41f78f5a7f133ad3f3111e330a636c80c3e3c70679 (confirm with AgentRegistry.SELF_REGISTER_TYPEHASH()). Signer must match signer in the typed data. On success, nonces(signer) increments.

​
Signing flow

1

Get a quote

GET /agents/register/quote?signer=0x... returns domain fields, selfRegisterTypehash, signerNonce, and fee metadata.
2

Sign SelfRegister

Sign typed data with all eight fields. Set linkERC8004: false and erc8004AgentId: 0 when not linking an ERC-8004 identity.
3

Submit

POST /agents/register (API relayer) or selfRegisterAgent on-chain (signer pays gas and on-chain fee when non-zero).
For HTTP relay, see Register an agent.

​
EIP-712: OpenPosition

Off-chain signing reference for TradeRouter agent intents. Full schema, exit ladder hashing, validation checklist, and additional intent types (AddToPosition, ReducePosition, UpdateExitLadder) are in contracts/docs/position-intent-eip712.md.

​
Domain

​
Types

Primary type OpenPosition:
The signed payload includes exitsHash (hash of the exit ladder), not the raw exits array. On-chain openPosition calldata must include the full exits array; the router recomputes the hash and reverts with InvalidSignature on mismatch. Signer must be AgentRegistry.signerOf(agentId). Executor submits with EXECUTOR_ROLE. The same nonce/deadline/domain rules apply to AddToPosition, ReducePosition, and UpdateExitLadder.

​
Trade-time enforcement

TradeRouter enforces allocation, trade size, daily turnover, daily realized loss (maxDailyLossBps), and exit bounds on open/add/ladder update. Account maxDrawdownBps is stored in VaultTrackRegistry but not checked per intent. Operator forceClose requires agent Suspended status.

​
Signing flow

1

Build the exit ladder

Hash each rule as keccak256(abi.encode(triggerType, triggerBps, exitBps)), then hash the array into exitsHash. See the contracts doc for stop-loss ordering and vault track bounds.
2

Sign OpenPosition

Sign typed data with domain above. Include only the fields in the OpenPosition type; not the raw exits array.
3

Submit via executor

An account with EXECUTOR_ROLE calls TradeRouter.openPosition(intent, signature) with the full PositionIntent struct including exits. On success, nonces(agentId) increments.
For HTTP relay, see Trade.
