# useExchangeAccounts

The `useExchangeAccounts` hook provides functionality for managing exchange accounts and performing exchange-related operations. It allows users to retrieve their exchange accounts, view transaction history, and execute transfers between exchange accounts.

This hook integrates with the Dynamic SDK to handle exchange operations across different blockchain networks and exchange platforms.

<Note>
  This hook supports the [Fund from Exchange](/money-and-funding/fund-from-exchange) feature, allowing users to transfer funds directly from their exchange accounts to their wallets.
</Note>

### Available Methods

* **[exchangeTransfer](#exchangetransfer)** - Execute transfers between exchange accounts
* **[getExchangeTransactions](#getexchangetransactions)** - Retrieve transaction history for exchange accounts
* **[getExchangeUserAccounts](#getexchangeuseraccounts)** - Get all user accounts for a specific exchange

    useExchangeAccounts();

  const handleTransfer = async () => {
    try {
      const result = await exchangeTransfer({
        exchange: ExchangeKeyEnum.Coinbase,
        transferRequest: {
          to: '0xRecipient',
          amount: 1,
          currency: 'USDC',
          network: 'ethereum',

      });
      console.log('Transfer successful:', result);
    } catch (error) {
      console.error('Transfer failed:', error);
    }
  };

  const loadAccounts = async () => {
    const accounts = await getExchangeUserAccounts({
      exchange: ExchangeKeyEnum.Coinbase,
    });
    console.log('User accounts:', accounts);
  };

  const loadTransactions = async () => {
    const transactions = await getExchangeTransactions({
      exchange: ExchangeKeyEnum.Coinbase,
    });
    console.log('Transactions:', transactions);
  };

  return (
    <div>
      <button onClick={handleTransfer}>Transfer</button>
      <button onClick={loadAccounts}>Load Accounts</button>
      <button onClick={loadTransactions}>Load Transactions</button>
    </div>
  );
}
```

## Error Handling

The hook throws `DynamicError` with specific error codes when operations fail:

* `UnprocessableEntityErrorCode.InvalidTransferCurrency`: Thrown when no account is found for the specified currency during transfer operations.

## Dependencies

This hook depends on:

* `useInternalDynamicContext` for accessing wallet and network information
* Dynamic SDK data layer for API calls
* Environment configuration for API endpoints
