Initialization

const solana = new SolanaHelper("https://api.mainnet-beta.solana.com");

Connect to the Solana Blockchain network and Switch between different network endpoints dynamically.

Account Management

We have integrated handful features just like creating new accounts, restore accounts from secret keys Fetching account details including balance and account info, requesting SOL sirdrops to accounts and fetching account details for multiple accounts.

1. Creating a new Account

const newAccount = solana.createAccount();

2. Restoring an account from a secret key.

const restoredAccount = solana.createAccountFromSecretKey(secretKey);

3. Fetching account balance

solana.getAccountBalance(account.publicKey).then(balance => console.log(balance));

4. Requesting airdrop to an account

solana.requestAirdrop(account.publicKey, 1000000).then(signature => console.log(signature));

5. Fetching account details for multiple accounts

solana.getMultipleAccountInfo([account1.publicKey, account2.publicKey]).then(accountInfos => console.log(accountInfos));

Transaction Handling

Transaction handling in "solana-helper" includes sending transactions between accounts, getting transaction details, simulating transactions without sending them, and retrieving recent account transactions. These features facilitate efficient management and monitoring of transactions on the Solana blockchain.

1. Sending a transaction between accounts

solana.sendTransaction(senderAccount, receiverAccount, 1000000).then(signature => console.log(signature));

2. Getting transaction details

solana.getTransactionDetails(transactionSignature).then(details => console.log(details));

3. Simulating a transaction without sending it.

solana.simulateTransaction(senderAccount, receiverAccount, 1000000).then(result => console.log(result));

4. Retrieving recent transaction for an account

solana.getRecentTransactions(account.publicKey).then(transactions => console.log(transactions));

Smart Contract Interactions

This package simplifies smart contract interactions by facilitating the deployment of programs with multiple instructions, calling methods on contracts with parameters, and retrieving program account information. This streamlines the development process and enhances efficiency when interacting with Solana smart contracts.

1. Deploying a program with multiple instructions

solana.deployProgramWithInstructions(programInstructions, senderAccount).then(signature => console.log(signature));

2. Calling a method on a smart contract with parameters.

solana.invokeContractMethod(contractProgramId, methodName, methodArguments, senderAccount).then(signature => console.log(signature));
