Checking Aptos Wallet Account Type

Checking Aptos Wallet Account Type

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

Usage

import { isAptosWalletAccount } from '@dynamic-labs-sdk/aptos';
import { getPrimaryWalletAccount } from '@dynamic-labs-sdk/client';

const walletAccount = getPrimaryWalletAccount();

if (walletAccount && isAptosWalletAccount(walletAccount)) {
  // walletAccount is now typed as AptosWalletAccount
  console.log('Aptos address:', walletAccount.address);
}

Parameters

Parameter	Type	Description
walletAccount	WalletAccount	The wallet account to check

Returns

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

React

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

import { isAptosWalletAccount } from '@dynamic-labs-sdk/aptos';
import { useGetWalletAccounts } from '@dynamic-labs-sdk/react-hooks';

function AptosWalletDisplay() {
  const { data: walletAccounts = [] } = useGetWalletAccounts();
  const aptosAccount = walletAccounts.find(isAptosWalletAccount);

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