How to get the Sun Scale change for a pumping exchange in Solana
From the latest updates from Solana, it is not possible to directly obtain the change of sun (solana) through the Gettransaction 'method. However, I can guide it through the process of getting this.
Understanding the transaction response
When using the Solana API for transactions, such asGettransaction ‘The type of transaction response includes multiple properties, including the current balance of various assets.
Gettransaction (), you are just getting the Bombefun token balance. Data with additional information to calculate the sun,
Pump change transaction structure **
To perform a Solna pumping exchange, you will need to perform multiple transactions for each asset involved in the exchange. Here is an example of how you can structure these transactions:
`TypeScript
// pump change transaction structure
PUMPFUNSWAPTRANSATION TYPE = {
Account0: String,
Account1: String,
Data: Uint8array,
};
// Create and pump exchange transaction
CONST PUMPFUNSWAPTX = {
Accounts: [
{Name: “Pumpfun”, type: “Pudkey”, public: “0x … pumpfun_token_pubkey”},
{Name: “Account1”, Type: “Pubkey”, public: “0x … account1_pubkey”},
{Name: “Data”, type: “Bytes”, data: uint8array.from (…),
// additional accounts and data for exchange
},
],
};
// Create a transaction object with the Pumpfun swap transaction structure
CONST TX = {
Account0: “Pumpfun”,
Account1: “Account1”,
Data: Pumpfinswaptx,
};
`
Calculating the Sol Balance Change
Several transactions for each asset involved in the exchange. Here is an example of how you can do this:
`TypeScript
// Create a transaction object with various pumping exchange transactions
Const Txs: pumpfunswaptransaction [] = [];
for (let’s go i = 0; i <10; i ++) {
CONCT 1 = “Account1” + string.fromcharcode (97 + I); // Generate account names for each asset
CONST Data = uint8array.from ([…], () => (i * 16) .Tostring (16)); // generate and random bytes
CONST PUMPFUNSWAPTX = {
Accounts: [
{Name: “Pumpfun”, type: “public”, public: 0x $ {account1}},
{Name: “Data”, type: “Bytes”, data: uint8array.from (…, …), / additional accounts and data /},
],
};
txs.push (pumpfunswaptx);
}
// Create a transaction object with pump change transactions
CONST TX = {
Account0: “Pumpfun”,
Account1: “Account1” + string.fromcharcode (97, 9),
Data: Pumpfinswaptx,
};
// Send the transaction (sending solo transactions)
SubStertransaction (TX);
`
NOTE:
The above example assumes and the simple scenario of pump change. Asset Swaps and Additional Accounts.
The Gettransaction 'method does not provide direct access to the sun's balance change. However, by performing several transactions for each asset involved in the exchange, you can calculate the desired change of the Sol Balance.
