Zero-Gas Autonomous Agents: Account Abstraction on Base L2

Autonomous AI agents break down in production for a pedestrian reason: key management.

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. If you store sufficient ETH for thousands of iterations, you hand an insecure script an existential attack vector. If the agent gets compromised or enters an uncontrolled loop, the balance disappears in seconds.

On Base L2 (Chain ID 8453 ), gas is cheap—fractions of a cent per transfer—yet the manual friction of funding an EOA remains prohibitive.…
