Configure the wallet

Wallet configuration

import { http } from 'viem';
import { bsc, mainnet } from 'viem/chains';
import {
  createD0fiWalletConfig,
  d0fiSolanaMainnet,
} from '@d0fi/checkout-react';

export const d0WalletConfig = createD0fiWalletConfig({
  appName: 'Your app',
  chains: [mainnet, bsc],
  transports: {
    [mainnet.id]: http(import.meta.env.VITE_ETH_RPC_URL),
    [bsc.id]: http(import.meta.env.VITE_BSC_RPC_URL),
  },
  solana: {
    enabled: true,
    networks: [d0fiSolanaMainnet],
  },
  ssr: true,
  autoConnect: true,
});

Mount the provider

import { D0fiWalletProvider } from '@d0fi/checkout-react';

<D0fiWalletProvider config={d0WalletConfig}>
  <App />
</D0fiWalletProvider>

Hooks such as useD0fiAccount anduseD0fiWalletClient must run inside this provider.

Wallet discovery

D0 discovers installed EIP-6963/EIP-1193 wallets for Ethereum and BNB Smart Chain, and Wallet Standard providers for Solana. Connecting does not sign a message or submit a transaction automatically.

TRON signing remains host-owned. Connect your compatible TRON provider, then map its address, wallet name and connection state intopartnerContractDeposit.account when the selected policy uses TRON.

RPC requirements

Use browser-safe HTTPS RPC endpoints for every enabled network. Never place private API credentials in a frontend environment variable.
