Quick Start

Connect to RPC, create a signer, and read your first typed Solana data.

This page gives you a fast tour of the three building blocks most apps start with:

  1. a typed RPC client
  2. a signer
  3. an account read

Create an RPC client#

Start with a typed RPC client. It gives you method-specific helpers instead of building raw JSON-RPC requests by hand. 

import 'package:solana_kit/solana_kit.dart';

final rpc = createSolanaRpc(url: 'https://api.devnet.solana.com');

final slot = await rpc.getSlot().send();
final latestBlockhash = await rpc.getLatestBlockhash().send();

print('Current slot: $slot');
print('Latest blockhash: ${latestBlockhash.value.blockhash}');

Use solana_kit_rpc_subscriptions alongside solana_kit_rpc when you also need websocket notifications for accounts, signatures, logs, or slots.

Generate a signer#

Most app flows need a signer for fee payment, message signing, or transaction submission. generateKeyPair() creates a new Ed25519 key pair and returns a KeyPairSigner. 

import 'package:solana_kit/solana_kit.dart';

final signer = await generateKeyPair();

print('Address: ${signer.address}');

Use key-pair signers for local development, testing, and server-side flows. For wallet-driven applications, you can also model fee-payer, partial, and sending signers explicitly with solana_kit_signers.

Fetch an account#

Use fetchEncodedAccount when you want the raw account bytes plus its Solana metadata. Decode it later with the codec or parser that matches your program. 

import 'dart:typed_data';

import 'package:solana_kit/solana_kit.dart';

final rpc = createSolanaRpc(url: 'https://api.devnet.solana.com');
const address = Address('11111111111111111111111111111111');

final maybeAccount = await fetchEncodedAccount(rpc, address);

switch (maybeAccount) {
  case ExistingAccount<Uint8List>(:final account):
    print('Owner: ${account.programAddress}');
    print('Bytes: ${account.data.length}');
  case NonExistingAccount():
    print('No account exists at $address');
}

Use fetchJsonParsedAccount when the RPC can return a structured jsonParsed representation for a well-known program.
