Checking Bitcoin Wallet Account Type

Checking Bitcoin Wallet Account Type

When working with multiple blockchain types, you may need to check if a wallet account is specifically a Bitcoin wallet account. The isBitcoinWalletAccount type guard function helps you narrow down the type safely.

Usage

import { isBitcoinWalletAccount } from '@dynamic-labs-sdk/bitcoin';
import { getPrimaryWalletAccount } from '@dynamic-labs-sdk/client';

const walletAccount = getPrimaryWalletAccount();

if (walletAccount && isBitcoinWalletAccount(walletAccount)) {
  // walletAccount is now typed as BitcoinWalletAccount
  console.log('Bitcoin address:', walletAccount.address);
}

Parameters

Parameter	Type	Description
walletAccount	WalletAccount	The wallet account to check

Returns

boolean - Returns true if the wallet account is a Bitcoin wallet account, false otherwise. Also acts as a TypeScript type guard, narrowing the type to BitcoinWalletAccount.

React

isBitcoinWalletAccount is a synchronous type guard that works the same in React. Use it to filter wallet accounts reactively:

import { isBitcoinWalletAccount } from '@dynamic-labs-sdk/bitcoin';
import { useGetWalletAccounts } from '@dynamic-labs-sdk/react-hooks';

function BitcoinAddress() {
  const { data: walletAccounts = [] } = useGetWalletAccounts();
  const btcAccount = walletAccounts.find(isBitcoinWalletAccount);

  if (!btcAccount) return <p>No Bitcoin wallet connected</p>;
  return <p>Bitcoin address: {btcAccount.address}</p>;
}
