Agents.sol

Overview

The Agents.sol contract is the core registry and economic coordination layer for Nexis AI agents. It manages agent registration, staking mechanisms, reputation systems, proof-of-inference recording, and delegation permissions. The contract is implemented as an upgradeable (UUPS) module with role-based access control. Contract Location: /nexis-appchain/packages/contracts-bedrock/contracts/Agents.sol

Key Features

Agent Registration: Decentralized registry for AI agents with metadata and service endpoints
Multi-Asset Staking: Support for ETH and ERC20 token staking with unbonding periods
Reputation System: Multi-dimensional reputation tracking across reliability, accuracy, performance, and trustworthiness
Proof of Inference: On-chain commitment and attestation of AI model outputs
Delegation Framework: Granular permission delegation for metadata, inference, and withdrawal operations
Treasury Integration: Automated routing of slashed stakes and penalties to treasury pools

Accuracy	`keccak256("accuracy")`	Inference correctness, prediction quality
Performance	`keccak256("performance")`	Latency, throughput, resource efficiency
Trustworthiness	`keccak256("trustworthiness")`	Security, data privacy, ethical behavior

Each dimension is weighted equally by default (2500 BPS each = 25%).

// 1. Register agent
const agentId = ethers.utils.keccak256(ethers.utils.toUtf8Bytes("my-agent"));
await agentsContract.register(
    agentId,
    "ipfs://QmMetadata...",
    "https://api.myagent.com/v1"

// 2. Stake ETH
await agentsContract.stakeETH(agentId, {
    value: ethers.utils.parseEther("10")

// 3. Delegate inference permission to oracle
const oracleAddress = "0x5678...";
const PERMISSION_INFERENCE = await agentsContract.PERMISSION_INFERENCE();
await agentsContract.setDelegate(agentId, oracleAddress, PERMISSION_INFERENCE, true);

// 4. Record inference (as oracle)
const inferenceId = await oracleContract.recordInferenceForAgent(agentId, ...);

// 5. Verifier attests
// (Handled by verifier role account)

// 6. Check reputation
const reputation = await agentsContract.aggregatedReputation(agentId);
console.log("Agent reputation:", reputation.toString());

// 7. Request withdrawal
await agentsContract.requestWithdrawal(
    agentId,
    ethers.constants.AddressZero,
    ethers.utils.parseEther("2")
);

// 8. Wait for unbonding period...

// 9. Claim withdrawal
await agentsContract.claimWithdrawals(
    agentId,
    ethers.constants.AddressZero,
    0,
    ethers.constants.AddressZero,
    false
);

Security Considerations

Reentrancy Protection

All external functions handling value transfers are protected with nonReentrant modifier.

Access Control

Critical functions use role-based access control
Agent owners must explicitly delegate permissions
Delegation is granular (metadata, inference, withdrawal)

Upgradeability

UUPS proxy pattern for upgrades
Only DEFAULT_ADMIN_ROLE can authorize upgrades

Stake Safety

Locked stake cannot be withdrawn
Unbonding periods prevent instant exits
Early exit penalties discourage premature withdrawal

Gas Optimization Tips

Batch Withdrawals: Use maxEntries parameter to limit gas costs
Queue Management: Cancel unwanted withdrawals to avoid processing costs
Delegation: Use delegates for frequent operations instead of owner multisig
View Functions: Always use callStatic for queries to avoid unnecessary transactions

Tasks.sol - Task marketplace with agent stake locking
Treasury.sol - Receives slashed stakes and penalties
Subscriptions.sol - Recurring payments to agents
