RPC Configuration

The SDK accepts any @solana/kit RPC client. For read-only usage, only rpc is required. Write operations additionally need rpcSubscriptions (WebSocket) for transaction confirmation and a signer.

Basic (read-only)

import { ARIO } from '@ar.io/sdk';
import { createSolanaRpc } from '@solana/kit';

const rpc = createSolanaRpc('https://api.mainnet-beta.solana.com');
const ario = ARIO.init({ rpc });

With writes (signer + WebSocket subscriptions)

import { ARIO } from '@ar.io/sdk';
import {
  createSolanaRpc,
  createSolanaRpcSubscriptions,
  createKeyPairSignerFromBytes,
} from '@solana/kit';

const rpc = createSolanaRpc('https://api.mainnet-beta.solana.com');
const rpcSubscriptions = createSolanaRpcSubscriptions(
  'wss://api.mainnet-beta.solana.com',
);
const signer = await createKeyPairSignerFromBytes(/* ... */);

const ario = ARIO.init({ rpc, rpcSubscriptions, signer });

Note: rpcSubscriptions opens a WebSocket connection and is only needed for writes. If your RPC provider doesn't expose a WebSocket endpoint, omit it and use the SDK in read-only mode.
