Frequently Asked Questions
Get clear answers on how our Account Abstraction Wallet Gateway Service works, from implementation to ongoing support.
A standard deployment for a custom ERC-4337-based wallet gateway takes 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, bundler/paymaster integration, and frontend SDK implementation. More complex features like multi-chain support or custom signature schemes can extend this timeline, which we scope and agree upon before project start.
