Product Description
The OpenClaw Smart Contracts Skill is an open-source skill module developed by CoinFello in collaboration with MetaMask, enabling personal AI agents (Moltbots) running on OpenClaw to securely execute on-chain smart contract transactions. Built on the MetaMask Smart Accounts Kit, this skill leverages ERC-4337 smart accounts and ERC-7710 delegation mechanisms to achieve fine-grained permission management, allowing users to complete blockchain transactions without exposing their private keys to AI agents.
This skill is the first blockchain integration in the OpenClaw ecosystem to gain widespread attention, introducing hardware-isolated keys and fine-grained delegation mechanisms, paving the way for broader agent ecosystems to harness on-chain capabilities.
Core Features/Characteristics
- Secure Key Management: Signing keys are stored on the user's device, and AI agents execute operations via ERC-7710 delegation without ever accessing private keys.
- Hardware-Isolated Keys: Utilizes hardware-level key isolation for protection.
- Natural Language-Driven: Users trigger blockchain operations through natural language prompts.
- Versatile On-Chain Operations:
- ERC-20 Token Swaps
- Cross-EVM Chain Bridging
- NFT Interactions
- Staking
- Lending
- Portfolio Rebalancing
- Multi-Step Transaction Strategies
- Evaluation Layer Verification: CoinFello converts instructions into delegated transactions and verifies them in the evaluation layer before execution.
- Self-Custody Priority: Designed for self-custody, currently in private Alpha stage.
