Welcome to Blink!
Blink is a hosted deposit flow for crypto apps. Your app opens a secure modal iframe powered by Blink, and users complete crypto and fiat deposits without ever leaving your site. There is nothing to PCI-scope, no wallet UI to build, and no on-chain logic to manage. Blink handles user authentication, wallet connection, on-chain transfers, and cross-chain bridging. Blink drops into your existing deposit stack as an additional funding option. You do not need to replace anything you already have. Add a single button alongside your current payment methods and Blink handles the rest. Both web and mobile SDKs are available. The web SDK renders the deposit flow in a modal iframe overlay. The mobile SDK opens the same hosted flow in an in-app browser and returns the result via a deep link callback. These docs cover everything from generating your key pair to shipping a production deposit integration. If you need the current support matrix for wallets, source chains, destination chains, tokens, and guest-versus-redeposit fees, see Supported Networks and Wallets. For fiat rollout details, including payment methods and KYC threshold behavior, see Fiat deposits and KYC.Integrate with an AI agent
