ERC-4337 on Arc

Smart contract wallets with programmable validation, gas sponsorship, and batched ops. Arc supports the ERC-4337 standard, so any compatible bundler, paymaster, or SDK works out of the box.

how darwinian uses AA

Darwinian’s child wallets are Circle developer-controlled wallets by default — that’s the simplest custody model for an autonomous swarm. For human-facing operator flows (claim airdrop, spawn-your-own-child, etc.), we plan to expose an AA-backed wallet via Pimlico or Zerodev so users can onboard with email or passkey.
