Solana: Bigint Error During Transfer of NFTS
NFTS (Non-Fungible Tokens) Using the Spl-Token Program on Your Local Solana Network. NFT Transfers: Bigint Errors.
The Problem:
When transferring an nft from one account to another, the transferfunction may throw an error due to a bigint (a large integer type) mismatch between the two accounts. This can happen when the Transaction'samountparameter.
The Error:
Here's an example of what the error might look like in your code:
JavaScript
Const {Connection, Publicewy, Transaction, Keypair} = Require (‘@Solana/Web3.js’);
// Create a New Key Pair for the Sender
constanePair = keypair.genate ();
// Define the Spl-Token Program’s Connection and Keys
Const Connection = New Connection (‘
constokenprogramid = ‘your_spl_token_program_id’;
Const spltokenaccountid = ‘your_spl_token_account_id’;
// Create a Transaction for Transferring an NFT
Const Transaction = New Transaction ()
.dd (
[
// Set The Transfer Parameters
{
Account0: Spltokenaccountid,
Amount: Bigint (1),
Pubkey: Spltokenprogramid.topublickey (),
Pubkey: SangerKeyPair.Publickey.tobase58 (),
},
],
);
// Attempt to transfer the NFT Without Error
transaction.sign (sorderkeypair);
connection.sendtransaction (transaction);
// If this line trouss an error, it means there was a bigint mismatch
`
The Solution:
AMOUNTPARAMETER IS VALID. Here are some steps to resolve the issue:
- Check account balances:
2.
.
Here's an updated example that addresses these issues:
JavaScript
Const {Connection, Publicewy, Transaction, Keypair} = Require (‘@Solana/Web3.js’);
// Create a New Key Pair for the Sender
constanePair = keypair.genate ();
// Define the Spl-Token Program’s Connection and Keys
Const Connection = New Connection (‘
constokenprogramid = ‘your_spl_token_program_id’;
Const spltokenaccountid = ‘your_spl_token_account_id’;
// CALCULATE THE REQUIRED AMOUNT IN BIGINTS
Const requiredamount = 1n;
let availablebalance = spltokenaccountid.balances.get (spltokenaccountid.publickey) .amount;
// Check If Enough Balance is available for the Transfer
if (availablebalance
Throw New Error (‘Insufficient Balance’);
}
// Create a Transaction with the Updated Parameters
Const Transaction = New Transaction ()
.dd (
[
// Set The Transfer Parameters
{
Account0: Spltokenaccountid,
Amount: Bigint (Requiredamount),
Pubkey: Spltokenprogramid.topublickey (),
Pubkey: SangerKeyPair.Publickey.tobase58 (),
},
],
);
// Attempt to transfer the NFT Without Error
transaction.sign (sorderkeypair);
connection.sendtransaction (transaction);
// If this line does not throw an error, it means everything is valid
`
By following these steps and updating your code accordingly, you should be able to resolve the bigint during during NFT transfers.
