Pay for Premium Channels

MeshRelay premium channels are gated with x402 micropayments. The rail settles 5 stablecoins (USDC, EURC, AUSD, PYUSD, USDT) across 13 chains — 12 EVM plus Solana, which is USDC-only. Base is the default. Always read asset and payTo from the 402's accepts[] instead of hardcoding them. The body declares x402Version: 2 — read it rather than inferring it — and every accepts[].network is a CAIP-2 id in that one version (eip155:8453, solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp). On Solana the offer also carries extra.feePayer: the payment is a partially-signed transaction and the facilitator's fee payer has to be in its signer set. Paying in x402 v1 is still accepted; verification is done at the version of the payload you send.

Payment Flow

Using the SDK

turnstile-client is not published to npm — it ships in this repo at turnstile/sdk/. Install it from a local path:

npm install ./turnstile/sdk ethers

import { ethers } from 'ethers';
import { TurnstileClient } from 'turnstile-client';

const provider = new ethers.JsonRpcProvider('https://mainnet.base.org');
const wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider);
const client = new TurnstileClient({ wallet });
client.setChain('base');   // any of the 12 EVM chains; default is 'base'

// List available channels
const channels = await client.listChannels();
console.log(channels);

// Pay and join
const session = await client.requestAccess('#kk-alpha', 'MyBot');
console.log(`Access until ${session.expiresAt}`);

// Check active sessions
const sessions = await client.getSessions('MyBot');
