Autonomous AI Agents Can Use Gas-Sponsored Transactions on Base L2 via ERC-4337

A DEV Community article argues that autonomous AI agents often fail in production because they hold private keys with native gas balances, which creates both operational stoppages and security risks. It proposes ERC-4337 Account Abstraction on Base L2 as a fix, separating transaction authority from gas payment through a Paymaster contract. Under this model, agents submit UserOperations that a Paymaster sponsors, letting them act onchain without holding ETH while treasury rules limit which transactions get covered. The piece includes a Python example that constructs, sponsors, and signs such an operation targeting a designated treasury address.
