x402 Solana Payment Server

x402 Solana Payment Server is an open-source Rust server template for HTTP APIs that accept USDC payments on Solana through the x402 protocol. It includes implementations for Axum, Actix and Rocket, plus a testing frontend and example free, health-check and payment-protected routes.

Practical overview

When it fits

Use it when developing a Rust HTTP API that needs Solana USDC payments for protected content and you want a framework-specific starting template.

Who it is for

  • Rust developers building HTTP APIs with paid access to content or data.
  • Teams that want to add x402 payment handling to routes using Axum, Actix or Rocket.

Documented uses

  • Create a Rust API server with an x402 payment flow for Solana.
  • Gate selected endpoints behind USDC payments while retaining free endpoints.
  • Configure a receiving wallet, network, price and facilitator.
  • Use the documented payment-verification pattern when adding protected routes.
Before you choose

Requirements & limits

The repository is public and lists an MIT license. The documented server setup uses Rust and Cargo; its project generator uses npx.

  • Select among Axum, Actix and Rocket implementations.
  • Set the required RECEIVER_WALLET_ADDRESS; the documented network setting defaults to devnet and lists mainnet as an option.
  • The example payment flow relies on a facilitator to verify and settle transactions.
  • The repository includes a web testing frontend as well as health, free and USDC-protected example endpoints.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up a Rust server project with x402

Generate a project, choose a framework and configure the wallet and server settings described in the README.

Before you start

  • Node.js with npx for the project generator
  • Rust and Cargo to run the server
  • A Solana receiving-wallet address

Steps

  1. Run the command below and use the interactive setup wizard to select Axum, Actix or Rocket.

    Documented command
    npx github:crypto-priest/x402-solana-rust my-project

  2. Copy .env.example to .env and set RECEIVER_WALLET_ADDRESS.

  3. Adjust optional settings as needed, including SOLANA_NETWORK, SOLANA_RPC_URL, USDC_MINT_ADDRESS, DEFAULT_PRICE and FACILITATOR_URL.

  4. Start the server with the command below.

    Documented command
    cargo run

Expected outcome

A generated Rust server configured with the selected framework and a receiving wallet; the README says it starts on `http://localhost:3000`.

Guide limitations

  • The guide covers the documented local setup; it does not establish deployment or production-operation steps.
  • The default network is devnet. Mainnet is listed as an available SOLANA_NETWORK setting.
