RPC Reference

The 1auth provider implements the EIP-1193 interface, making it compatible with viem, wagmi, ethers, and other Ethereum libraries.

Overview

All RPC methods can be called via the standard request interface:

const result = await provider.request({
  method: 'method_name',
  params: [...],
})

})
 
const provider = createOneAuthProvider({
  client,
  chainId: 8453, // Base
})
 
// Request accounts
const accounts = await provider.request({

})

Cross-Chain with tokenRequests

For ERC20 transfers and contract calls that need tokens, include tokenRequests to enable automatic cross-chain funding. The user can pay from any chain - the orchestrator handles bridging and swaps automatically.

import { encodeFunctionData, parseUnits } from 'viem';
 
const amount = parseUnits('100', 6); // 100 USDC
const transferData = encodeFunctionData({
  abi: erc20Abi,
  functionName: 'transfer',
  args: [recipient, amount],
});
 
await provider.request({
  method: 'eth_sendTransaction',
  params: [{
    to: USDC_ADDRESS,
    data: transferData,
    tokenRequests: [{ token: USDC_ADDRESS, amount }],
  }],
});

See Token Requests for detailed documentation.
