Usage

Client

import { AuthCaptureEvmScheme } from "@x402r/evm/auth-capture/client";
import { x402Client } from "@x402/core/client";

const client = new x402Client();
client.register("eip155:84532", new AuthCaptureEvmScheme(signer));

Server

import { AuthCaptureEvmScheme } from "@x402r/evm/auth-capture/server";
import { x402ResourceServer } from "@x402/core/server";

const server = new x402ResourceServer(facilitatorClient);
server.register("eip155:84532", new AuthCaptureEvmScheme());

Facilitator

The auth-capture scheme integrates with x402's facilitator using the same FacilitatorEvmSigner as x402's exact scheme:

import { AuthCaptureEvmScheme } from "@x402r/evm/auth-capture/facilitator";
import { x402Facilitator } from "@x402/core/facilitator";
import { toFacilitatorEvmSigner } from "@x402/evm";

const evmSigner = toFacilitatorEvmSigner({ address, ...clients });

const facilitator = new x402Facilitator();
facilitator.register("eip155:84532", new AuthCaptureEvmScheme(evmSigner));
