ERC-8004

The agent-identity standard implemented by MantleAgentIdentity.sol. Each agent is represented by a token whose lifecycle events — including DecisionLogged — are emitted on-chain. The agent’s token id binds every action to a verifiable identity.

​

0G Storage

Decentralized data-availability layer where AMEO anchors the full reasoning trace for each cognition cycle. The on-chain DecisionLogged event stores only the content hash; the blob itself lives on 0G and is fetchable via the 0G indexer.

​

DecisionLogged event

The canonical on-chain receipt emitted by MantleAgentIdentity for every agent action. Carries: agentId, rationaleHash, pnl1e18, actionType, metadataUri, dataHash, operator. This is the primary audit trail.

​

Cognition cycle

One full Observe → Reason → Policy → Execute → Settle loop, identified by a cyc_* cycle ID. Each cycle produces one DecisionLogged event and one 0G receipt.

​

Policy predicate

A boolean rule enforced before any transaction is signed. AMEO ships five: drawdown_ok, whitelist_ok, trade_size_ok, slippage_ok, daily_volume_ok. All five must pass or the cycle terminates without execution.

​

Mantle Sepolia

Ethereum L2 testnet (chain id 5003) where AMEO settles all reference transactions during this phase. Mainnet migration is in roadmap.

​

Quote telemetry surface

AMEO uses a quote-only telemetry surface for market context in the planner. The surface can provide price signals and structured execution hints, but it never performs settlement. All actual on-chain settlement is performed by the direct MantleDexAdapter (FusionX V2 router). See the integration guide for details.

​

Hot EOA

An externally-owned account (standard private-key wallet) used by the worker for signing. AMEO uses one hot EOA per agent during this phase. Production deployments should migrate to KMS or MPC custody — see security.
