Description
NexusAgent is the world's first autonomous AI agent that funds its own intelligence using delegated MetaMask Smart Accounts and ERC-7710 on-chain permissions.
Key Innovations:
- Sign ONCE — Agent runs forever within a smart contract-enforced USDC budget
- ERC-7710 Delegation — Cryptographically bounded spending, no trusted intermediaries
- x402 Micropayments — Each Venice AI call costs $0.003 USDC, paid automatically
- Zero ETH Gas — All transactions relayed via 1Shot API, user never touches ETH
- 4-Level Delegation Cascade — User → Orchestrator → Researcher → Analyst → Synthesizer
- EIP-7702 Smart Accounts — MetaMask stateless smart accounts on Base mainnet
