Gasless Transactions
Agents never need AVAX or ETH for gas. The facilitator executes transferWithAuthorization via EIP-3009.
Trustless by Design
EIP-712 signature verification ensures cryptographically valid payments before on-chain execution.
Multi-Network Support
Supports Avalanche (Fuji testnet and C-Chain mainnet), Base (Sepolia testnet and mainnet), and Celo (Sepolia testnet and mainnet).
Instant Settlement
Complete payment verification and on-chain settlement in ~2-3 seconds end-to-end.
Integrate in Minutes
import { Hono } from "hono";
import { paymentMiddleware, Network } from "x402-hono";
const app = new Hono();
// Configure payment middleware
app.use(paymentMiddleware(
"0xYourAddress",
{
"/protected-route": {
price: "$0.01",

What is x402?
x402 is a protocol for stateless, per-request payments over HTTP. Clients attach a signed payment payload to each request. The facilitator verifies it, executes the on-chain transfer, and grants access to protected resources—all without accounts, wallets, or user registration.
