Solana WalletSendTransactionError: Unexpected error when sending transaction

=================================================================

The WalletSendTransactionError exception occurs when a wallet send transaction fails in Solana. This can happen for various reasons such as insufficient funds, invalid address, or network congestion.

In this article, we will explore the possible causes of the WalletSendTransactionError and provide solutions to resolve the issue.

Possible Causes

• Insufficient Funds

• Invalid Address

• Network Congestion

1. Insufficient Funds

If you’re trying to send a transaction that requires more funds than your wallet has, you’ll get an error like WalletSendTransactionError: Unexpected error when sending transaction. This is because Solana transactions require the same amount of funds regardless of the sender’s account balance.

To resolve this issue:

• Ensure your wallet account has sufficient funds for the transaction.

• You can check your wallet’s funds by calling the get_balance method before sending the transaction.

Example (in JavaScript):

const accountBalance = await account.get_balance();

if (accountBalance < 1000000) {

    throw new WalletSendTransactionError('Insufficient funds');

}

2. Invalid Address

If your address is invalid or not a valid Solana account, you’ll get an error like WalletSendTransactionError: Unexpected error when sending transaction. This can happen if the address has been compromised or is not properly formatted.

To resolve this issue:

• Ensure that your address is valid and follows the standard format of [owner:public_key].

• If the address is invalid, you might need to regenerate it or use a different address.

Example (in JavaScript):

const isValidAddress = account.is_valid();

if (!isValidAddress) {

    throw new WalletSendTransactionError('Invalid address');

}

3. Network Congestion

If there’s network congestion affecting Solana, you might receive an error like WalletSendTransactionError: Unexpected error when sending transaction. This can happen due to various reasons such as high network activity or outages.

To resolve this issue:

• Try refreshing the page or re-initiating the wallet send operation.

• Check the Solana network status on their website to see if there are any issues affecting the network.

Example (in JavaScript):

const refreshWalletSend = async () => {

    try {

        // Refresh the wallet send operation

        await account.refresh_send();

    } catch (error) {

        throw new WalletSendTransactionError('Network congestion');

    }

};

Conclusion

To resolve the WalletSendTransactionError issue, it’s essential to ensure that your wallet has sufficient funds and is properly formatted. If you’re experiencing network issues, try refreshing the page or re-initiating the wallet send operation.

By understanding the possible causes of this error and implementing solutions, you should be able to overcome any challenges you face when sending transactions in Solana.

“`javascript

import { account } from ‘./account’;

import { WalletSendTransactionError } from ‘./error’;

const stakeAccount = async () => {

try {

// Get the public key of the stake account

const stakePublicKey = await account.get_public_key();

// Create a new transaction object

const tx = await account.
