In this article, we will take a detailed look at the process of restoring the historical data of the Solana account.

The Ledger Tool: A Tutorial

The Ledger tool is a powerful set of tools for working with blockchain data in Node.js. It offers various functions, including:

• Snapshots: Take a snapshot of your host’s account status. at a certain point in time.

• Transaction history: view the history of transactions up to the specified block number.

• Account Status: Receive account information before or after a specific transaction.

View account data before or after a transaction

To access your account history, you need to do the following:

• Take a snapshot of your host’s state: Use the register command with the -s option to take a snapshot of your host’s account state.

node --silent ledger snapshot --path /dev/solana

• Use Ledger API to retrieve transaction history and account status: After receiving a snapshot, use Ledger API to request transaction history up to a specified block number or after a specific transaction.

To get historical account data:

• Request transactions for the required range: use the log command with the -t option to specify the starting and ending block numbers.

node --silent ledger snapshot --path /dev/solana transaction request --from  --to 

• Filtering of transaction data by account: use the register command with the -a option to specify a specific account address.

For example:

node --silent ledger snapshot --path /dev/solana query transaction --from  --to  --to 

• Access to historical account data: After executing the above command, you will get access to the transaction history and account status for the specified range.

Examples of use cases

Here are some examples of how you can use these commands to retrieve historical account data:

• Retrieving account balances: use the register command with the -a option to request account balance data.

node --silent ledger snapshot --path /dev/solana query transaction --from  --to  --to 

• View Transaction History: Use the log command with the -t option to view transaction data up to the specified block number.

node --silent ledger snapshot --path /dev/solana transaction request --from  --to 

• Retrieving account status: Use the register command with the -a option to access account data after a specific transaction.

node --silent ledger snapshot --path /dev/solana query transaction --from  --to  --to
