Frequently Asked Questions
Get clear answers on how our User Operation screening service integrates, scales, and protects your smart accounts.
Our service integrates as a RPC middleware layer that sits between your bundler (like Stackup, Alchemy, or Pimlico) and the blockchain. You simply point your bundler's RPC to our endpoint. We support all major ERC-4337 bundlers and are compatible with popular SDKs (like ZeroDev, Biconomy, and Etherspot). Integration typically takes under 2 hours with our documented API.
