Zero‑Gas Autonomous Agents: Account Abstraction on Base L2

Описание и применение

Автономные агенты могут работать на Base L2 без баланса ETH, используя Paymaster ERC‑4337 для спонсорства газа.

Задача

Autonomous AI agents fail in production because they rely on an EOA private key for gas, leading to halts when gas runs out or security loss when the key is compromised.

Результат

Agents can now execute on Base L2 without holding ETH, reducing operational friction and improving security by isolating the private key from gas payments.

Рабочий процесс

• Create UserOperation with agent’s session key
• Send UserOperation to Base bundler RPC
• Bundler forwards to EntryPoint contract
• Paymaster validates target and call data
• Paymaster covers L2 execution and L1 data‑availability fee
• If validation fails, Paymaster refuses sponsorship and no gas is spent

Доказательства

Most architectures give an LLM or a deterministic runtime direct access to an EOA (Externally Owned Account) private key. If the wallet runs dry of native gas, the agent halts.

Источник

By offloading gas payments to an ERC‑4337 Paymaster, agents execute onchain actions with zero native ETH balances, while treasury controls restrict what transactions get sponsored.
