summary

All modifications to onchain data happen through transactions. Transactions are mostly a set of instructions that invoke Solana programs. Transactions are atomic, meaning they either succeed - if all the instructions have been executed properly - or fail as if the transaction hasn't been run at all

const transaction = new Transaction()

const sendSolInstruction = SystemProgram.transfer({
  fromPubkey: sender,
  toPubkey: recipient,
  lamports: LAMPORTS_PER_SOL * amount
})

transaction.add(sendSolInstruction)


const signature = sendAndConfirmTransaction(
  connection,
  transaction,
  [senderKeypair]
)

Solana Explorer

All transactions on the blockchain are publicly viewable on the Solana Explorer. For example, you could take the signature returned by sendAndConfirmTransaction() in the example above, search for that signature in the Solana Explorer, then see:

when it occurred

which block it was included in

the transaction fee

and more!


console.log(
  `✅ Loaded our own keypair, the destination public key, and connected to Solana`
);

const transaction = new Transaction();

const LAMPORTS_TO_SEND = 5000;

const sendSolInstruction = SystemProgram.transfer({
  fromPubkey: senderKeypair.publicKey,
  toPubkey,
  lamports: LAMPORTS_TO_SEND,
});

transaction.add(sendSolInstruction);

const signature = await sendAndConfirmTransaction(connection, transaction, [
  senderKeypair,
]);

console.log(
  `💸 Finished! Sent ${LAMPORTS_TO_SEND} to the address ${toPubkey}. `
);
console.log(`Transaction signature is ${signature}!`);
