framework-kit

framework-kit (@solana/client + @solana/react-hooks) is the Solana Foundation's reactive toolkit, built on @solana/kit. It is the recommended modern Solana stack: butr discovers and manages the wallet, framework-kit is the reactive RPC/data layer, and the wallet's Wallet Standard features supply signing and submission.

framework-kit runs its own Wallet Standard discovery (autoDiscover()). Here butr owns discovery and connection instead, so no walletConnectors are passed to createClient — framework-kit is used purely for reactive reads.

Provider

Create the client without wallet connectors and wrap the app. butr's WalletProvider stays the outer provider:

import { createClient } from "@solana/client";
import { SolanaProvider } from "@solana/react-hooks";

const client = createClient({ cluster: "devnet", commitment: "confirmed" });

<WalletProvider>
  <SolanaProvider client={client}>
    <App />
  </SolanaProvider>
</WalletProvider>;

Reactive balance

useBalance auto-fetches and watches the balance for butr's connected address — no manual refetch wiring:

import { useBalance } from "@solana/react-hooks";

const { error, fetching, lamports } = useBalance(wallet.account.walletAddress);
const balance = lamports !== null ? `${Number(lamports) / 1_000_000_000} SOL` : "…";

Sign and send a transaction

Transaction building rides on @solana/kit (the substrate framework-kit is built on); the wallet — managed by butr — signs and submits through solana:signAndSendTransaction, exactly as in the @solana/kit integration. Message signing uses solana:signMessage the same way.
