Overview

This section focuses on connecting to OneKey using the injected EIP‑1193 provider. No extra SDK is required for the web — detect and call the provider directly.

Recommended

• Web (Injected Provider):

  • Prefer window.$onekey.ethereum; fall back to window.ethereum as needed

  • Multi‑chain; see per‑chain sections for signing/transactions/events (ETH, BTC, Solana, NEAR, Nostr, WebLN)

Note: This section centers on the native provider flow based on EIP‑1193. If your app already uses Wallet Kits or needs compatibility guidance, see Support Wallet Kits and Compatible with MetaMask.

Minimal example (EVM)

const provider = window?.$onekey?.ethereum
  || window?.ethereum?.providers?.find(p => p?.isOneKey || p?.onekey)
  || window?.ethereum;
if (!provider) throw new Error('OneKey not detected');
const [account] = await provider.request({ method: 'eth_requestAccounts' });
console.log('Account:', account);

See Web (Injected Provider) for details.
