Create User

Register a new user sub-account under your builder and get their API key.

Usage

import { BuilderClient } from '@opinion-labs/opinion-clob-sdk';

const builder = new BuilderClient({
  host: 'https://openapi.opinion.trade/openapi',
  builderApiKey: 'YOUR_BUILDER_KEY',
  chainId: 56,
});

const result = await builder.createUser('0xUserWalletAddress...');

console.log(result.walletAddress);    // User's login wallet address
console.log(result.multiSigWallet);   // User's Gnosis Safe wallet address
console.log(result.apikey);           // User's API key - SAVE THIS!
console.log(result.builderName);      // Builder name
console.log(result.enableTrading);    // Whether trading is enabled

Parameters

Parameter	Type	Required	Description
walletAddress	string	Yes	User's EOA wallet address (0x-prefixed)

Response

interface UserInfo {
  apikey: string;              // API key (only returned during creation)
  walletAddress: string;       // User's login wallet address
  multiSigWallet: string;     // User's Gnosis Safe wallet address
  builderName: string;        // Builder name
  walletCreationTxHash?: string; // Safe creation transaction hash
  enableTrading: boolean;      // Whether trading approvals are set up
}

Notes

• The API key is returned only once during creation. Store it securely in your database.

• The Gnosis Safe wallet is created asynchronously (1-10 minutes). Poll getUser() until multiSigWallet is non-empty.

• If the user already exists, the API will return an error. Use getUser() to retrieve existing user info.

Polling for Safe Wallet

// Poll until Safe wallet is ready
let safeAddress = result.multiSigWallet;
while (!safeAddress) {
  await new Promise((r) => setTimeout(r, 30_000)); // Wait 30s
  const user = await builder.getUser('0xUserWalletAddress...');
  safeAddress = user.multiSigWallet;
}
console.log('Safe wallet ready:', safeAddress);
