Technical & Commercial Questions

EVM Wallet Integration FAQs

Answers to the most common questions CTOs and product leads ask when evaluating a wallet integration partner.

Standard integrations for a single chain (e.g., MetaMask, WalletConnect) are delivered in 2-3 weeks. Multi-chain deployments (e.g., adding support for Polygon, Arbitrum, Base) typically take 3-4 weeks. This includes development, rigorous testing on testnets, and a security review. We provide a detailed sprint plan upfront.
