Execution Layer

Definition
A controlled component that prepares, validates, signs, submits, and monitors a state-changing operation. In an agent workflow, it must treat model output as an untrusted proposal, not as authority to move funds or call a contract.

- ERC-4337: Account Abstraction Using Alt Mempool opens in a new tab
Supports: ERC-4337 describes smart-account validation and UserOperation flow, supporting explicit, implementation-specific validation rather than generic agent authority.
- OWASP: LLM06 Excessive Agency opens in a new tab
Supports: OWASP documents harmful state changes when applications grant broad tool authority to unexpected, ambiguous, or manipulated LLM output.

Key Takeaways
1
An agent execution layer validates and submits an operation; it is distinct from Ethereum's protocol execution layer.
2
Validate the exact chain, account, contract, method, parameters, asset, amount, counterparty, allowances, fee, nonce, expiry, simulation, and input sources.
3
Keep keys and broad wallet or RPC authority outside the model, with narrow revocable policies and a fresh approval after any change or retry.
4
Submission is not confirmation: record finality and stop on rejected, replaced, reorged, reverted, front-run, or partial outcomes.
Practical Example
A research tool prepares a transaction draft. Before signing, the execution layer shows the exact contract call, recipient, asset, amount, allowance change, fee, expiry, and simulation. The user approves that exact payload; a changed quote requires a new review, and a revert is shown as failure rather than retried automatically.

AgenticityAn informal way to describe how much an AI system can observe, plan, call tools, and act. It is not a standardized maturity score, a measure of trustworthiness, or permission to give an agent broad authority.

Agentic WalletA wallet or smart-account workflow that gives software an explicitly bounded ability to prepare or execute actions. It is an implementation pattern, not an ERC-4337 feature, safety guarantee, or reason to grant a model unrestricted signing authority.

MPC Wallet (Multi-Party Computation)A cryptographic design in which parties jointly perform a signing or other key operation without exposing their private inputs to one another. The security outcome depends on the threshold, implementation, device isolation, policy, recovery, and operators.
Strategy
Intent-Based TradingA design in which a user signs constraints for a desired outcome and a protocol or solver attempts settlement. A signed intent is an authorization with a specific trust and replay boundary, not a guarantee of price, route, MEV protection, or successful settlement.
