Title: SOLANA: Address table lookups not added to fortress transaction Message
Introduction
As a Developer Working with the Solana Blockchain, I’m Constantly Seeking Ways to Improve My Understanding and Optimization of the Various Messages Used In The Solana Protocol. Recently, I’ve encountered an issue that has bone frustrating my development process.
The problem: Address table lookups not added to fortress transaction Message
In order to retrieve account addresses for a fortress transaction, I need to look up the address tables (alt) associated with the accounts Involved in the Vesting Process. However, when using ‘fortress transaction’, the Addressstablelookup 'table is not included by default.
The issue:
To troubleshoot this issue, I started by checking the solana documentation and searching for any mentions offortress transactionMessages or Related functions. I Couldn't Find Any Information That Suggests Adding AnAdresstablelookup ‘Table To theFortress Transaction Message is a Required Step.
Solution: Adding Addesstablelookup
After Conducting Further Research, I Found that the Addressstablelookup function can be used to look up addresses in the solana blockchain. To add this function to the Vesting transaction 'Message, we need to use a specific type of transaction called Vesting transaction vestingand then callAddressstablelookup’.
Here’s an Example of how you can modify your code to add the Vestingtransactionvesting transaction:
`Solana
use solana program :: {account_info :: account info, program_error};
use solana_transaction_builder :: Transactionbuilder;
Struct Festation transaction vesting {
Account0: & Account info,
Account1: & Accountinfo,
}
fn main () -> result <(), string> {
Let Mut Builder = Transactionbuilder :: New ();
Let Vesting = Builder
.Create_Account (
& [
Account info :: from_hash (& vesting.account0.key.hash),
Account info :: from_hash (& vesting.account1.key.hash),
"", ","
10_000,
);
builder.apply (builder.finish ()). Unwrap ();
// Create A Fortress Transaction Vesting Transaction
Let Vesting = Fortress transaction vesting {
Account0: Vesting.Account1.clone (),,
Account1: Vesting.account0.clone (),,
};
// Define the function that will be called when the fortress is complete
fn on_vesting_complete (fortress: & fortress transaction vesting) -> Result <(), string> {
Let address_table_lookup = Addressstablelookup :: New ();
// Look up the addresses in The Solana Blockchain
for (index, account_info) in Vesting.account0.keys.iter (). Enumerate () {
if index == 1 {
// Find an address that matches the account info hash
Match Address_table_lookUp.find (& account_info.key.hash) {
Some (Address) => Println! ("Found address {}", Address),
None => Return Err ("Address not found" .to ()),
}
} Else {
println! ("Found another account {}", index);
}
}
OK(())
}
// call the on_vesting_complete function when the fortress is complete
builder.call_function (
& [
"on_vesting_complete",
Account info :: from_hash (& vesting.account0.key.hash),
Account info :: from_hash (& vesting.account1.key.hash),
"", ","
۱۰۰,
)
.unwrap ();
}
Conclusion
In Conclusion, Adding An Adresstablelookup Function to theVesting transaction Message Can Be A Useful Optimization for Retrieveing account Addresses.
