Title: Solve: Address Table Lookup Not Added to VestingTransaction Message
Introduction
As a developer working on the Solana blockchain, I am constantly looking for ways to improve the understanding and optimization of the various messages used in the Solana protocol. I recently encountered an issue that was making my development process uncomfortable.
Problem: Address Table Lookup Not Added to VestingTransaction Message
In order to retrieve the account addresses for a vesting transaction, I need to look up the address tables (ALT) associated with the accounts involved in the vesting process. However, when using VestingTransaction, the AddressTableLookup table is not included by default.
Problem:
To resolve this issue, I started by reviewing the Solana documentation and looking for any mention of VestingTransaction messages or related functions. I’m not sure if this is true or not, but I’m pretty sure it is.
Solution: Adding AddressTableLookup
After doing some more research, I found that the AddressTableLookup function can be used to look up addresses on the Solana blockchain. To add this function to the VestingTransaction message, we need to use a specific transaction type called VestingTransactionVesting and then call AddressTableLookup.
Here’s an example of how you can modify your code to add the VestingTransactionVesting transaction:
use solana-program::{account_info::Account_info, program_error};
use blame_transaction_builder::TransactionBuilder;
struct VestingTransactionVesting { .
account0: &AccountInfo,
account1: &AccountInfo,
} }
fn main() -> Result<(), String> {
let mut builder = TransactionBuilder::new();
easy vesting = builder
.create_account(
&[
AccountInfo::from_hash(&vesting.account0.key.hash),
AccountInfo::from_hash(&vesting.account1.key.hash),
],
10_000,
);
builder use (builder. complete());
// Create VestingTransactionVesting transaction
easy vesting = VestingTransactionVesting {
account0: vesting.account1.clone(),
account1: vesting.account0.clone(),
};
// Define a function to be called when the vesting is complete
fn on_vesting_complete(vesting: &VestingTransactionVesting) -> Result<(), String> {
let address_table_lookup = AddressTableLookup::new();
// Look up addresses in the Solana blockchain
for (index, account_info) in vesting.account0.keys.iter().enumerate() {
if index == 1 {
// Find an address that matches the hash value of the account information
match address_table_lookup find ( & account_info . key . hash ) { .
Some(address) => println!("Found address {}", address),
None => return Err("Address not found".into()),
} }
} else {
println!("Found another account {}", index);
} }
} }
ok (())
} }
// Call the on_vesting_complete function when the insertion is complete
builder.call_function(
&[
"on_vesting_complete".
AccountInfo::from_hash(&vesting.account0.key.hash),
AccountInfo::from_hash(&vesting.account1.key.hash),
],
100,
)
.expand();
} }
Conclusion
Finally, adding the AddressTableLookup function to the VestingTransaction message can be a useful optimization for retrieving account addresses.
