@routexcc/chain-base

Base (L2) chain adapter for Routex — the multi-chain settlement cost router for the x402 payment protocol.

Install

npm install @routexcc/core @routexcc/chain-base

Usage

import { createBaseAdapter } from '@routexcc/chain-base';
import { createPublicClient, http } from 'viem';
import { base } from 'viem/chains';

const client = createPublicClient({
  chain: base,
  transport: http('https://base-mainnet.g.alchemy.com/v2/YOUR_KEY'),
});

const adapter = createBaseAdapter(client);
// Testnet: createBaseAdapter(client, { testnet: true })

Details

• Technology: viem (EVM)
• Finality: ~2000ms (L2 block time)
• Chain IDs: 8453 (mainnet), 84532 (Sepolia testnet)
• Signing: EIP-712 typed data with chain-specific domain separator
• RPC methods: eth_call, eth_gasPrice, eth_estimateGas

Exports

• createBaseAdapter(client, options?) — factory function
• EvmAdapter — shared EVM base class (also used by @routexcc/chain-polygon)

Non-Custodial

The adapter calls signer.sign() or signer.signTypedData() to construct payment payloads. It never accesses .privateKey, .secretKey, or .mnemonic.
