algorand-x402-typescript

Algorand x402 TypeScript integration uses a modular toolkit to connect clients, servers, and facilitators with AVM-based payment flows. It provides signer interfaces, scheme registration helpers, and CAIP-2 network handling for both browser and server environments across testnet and mainnet.

The x402 protocol enables HTTP-native payments, allowing TypeScript apps to orchestrate 402 payment flows using Algorand. You need it when building clients, servers, or facilitators that require AVM scheme registration and signer interfaces to bridge wallets or private keys to HTTP payment workflows.

Yes, x402 Algorand payments support Express, Hono, and Next.js on the server side, along with Fetch and Axios HTTP clients. The toolkit provides end-to-end payment flow guidance and example code to accelerate integration across these popular frameworks for both prototyped and production apps.

Signer interfaces bridge wallets or private keys to the x402 protocol in TypeScript. You register an AVM scheme with your chosen signer, then use the modular toolkit packages to handle CAIP-2 network identification and orchestrate 402 payment flows across testnet and mainnet environments.

Yes, the toolkit supports both testnet and mainnet environments for AVM-based payment flows. It includes CAIP-2 network handling for multi-network scenarios, ensuring TypeScript apps can properly manage scheme registration and signer interfaces across different Algorand network configurations.

Building a facilitator uses the modular TypeScript packages provided by the toolkit, combined with AVM scheme registration and signer interfaces. Optional Bazaar discovery extensions are available, and comprehensive reference material with example code helps accelerate facilitator integration for production deployment.
