Frequently Asked Questions
Get clear answers on deploying secure, gasless corporate wallets for your business operations.
A standard deployment for a multi-signature, gasless ERC-4337 wallet with 2-5 signers and basic policy rules takes 2-3 weeks from kickoff to mainnet launch. Complex deployments with custom paymasters, advanced spending limits, or integration with existing ERP systems typically take 4-6 weeks. We provide a detailed project timeline during the initial technical scoping call.
