Top Solana React Components for 2026.

Okay, before you even think about components, snag this: write a tiny copyIdl.js script in your Anchor project root. It grabs that mysolanaapp.json from target/idl/ and dumps it straight into your React app's src/idl.json. Run it after every program build. Why? Manually copying sucks, and you'll forget. Boom, state stays fresh across refreshes. In my experience, this saves like 20 minutes of swearing per dev session.

Wallet Adapter - Your Non Negotiable Starting Point

Look, every Solana React app needs wallet connection. @solana/wallet adapter react and its UI buddies are still king in 2026. Don't overthink it - install the full stack:

  • @solana/wallet adapter react
  • @solana/wallet adapter react ui
  • @solana/wallet adapter wallets
  • @solana/wallet adapter base

That's it. Wrap your App like this:

jsx

Define wallets with Phantom first - new PhantomWalletAdapter(). Users click WalletMultiButton, boom connected. Fees? Localhost is free, devnet airdrop 2 SOL via solana airdrop 2 YOUR_ADDRESS. Mainnet? ~0.000005 SOL per tx. Sound familiar? Yeah, it's that cheap.

But here's the thing - if wallet's not connected, just show the button centered. No value? Nudge 'em to create an account first. I usually add a state check: if (!wallet.connected) return <WalletMultiButton />;

Hook It Up with useWallet

  1. Import { useWallet } from '@solana/wallet adapter react';
  2. const wallet = useWallet();
  3. Use wallet.publicKey for signer, wallet.connected for gates.
  4. Sign tx: await wallet.signTransaction(tx);

Potential issue? Network mismatch. Phantom on localhost? Switch in wallet settings. Forgot? App errors with "invalid network." Fix: hardcode endpoint to match, like devnet "https://api.devnet.solana.com".

Anchor Program Integration - The Real Magic Component

So you've got your Rust program with Anchor. Built it? IDL ready? Drop it in src/idl.json. Now build a Program hook component. I call mine SolanaProgram.jsx. Import:

jsx import { Program, Provider } from '@project serum/anchor'; import { Connection, PublicKey } from '@solana/web3.js'; import idl from './idl.json';

Make a getProvider func:

jsx async function getProvider() { const network = "http://127.0.0.1:8899"; const connection = new Connection(network, 'processed'); return new Provider(connection, wallet, 'processed'); }

Then const program = new Program(idl, programID, provider);. programID is new PublicKey(idl.metadata.address). Why does this matter? Anchor auto generates RPC methods like program.rpc.create(). No manual instruction building. Pretty much writes your tx for you.

In my experience, generate a baseAccount Keypair once: const baseAccount = Keypair.generate();. Store its pubkey. Refresh loses it otherwise - users hate re creating counters.

Counter App Component - Copy Paste and Tweak

Here's a full Counter.jsx I ripped from a real project. Super short. Works.

jsx import { useState } from 'react'; import { Keypair } from '@solana/web3.js'; const Counter = ({ baseAccountPubkey }) => { const [value, setValue] = useState(null); const createCounter = async () => { const provider = await getProvider(); const program = new Program(idl, programID, provider); const baseAccount = Keypair.generate(); // Or load existing await program.rpc.create({ accounts: { baseAccount: baseAccount.publicKey, user: provider.wallet.publicKey, systemProgram: SystemProgram.programId, }, signers: [baseAccount] }); const account = await program.account.baseAccount.fetch(baseAccount.publicKey); setValue(account.count.toString()); }; const increment = async () => { // Similar, but rpc.increment({ accounts: { baseAccount: baseAccountPubkey } }); // Fetch and setValue }; return (
{!value && } {value && }
); };

Test it: anchor test first, then npm start. Tx fails? Check logs with solana logs. Common bug: space allocation wrong in Rust #[account(init, payer = user, space = 16 + 16)]. Bump to 8 + 8 + 8 for u64 count.

Now, scale it. This is your base for any stateful dApp. Blog posts? Swap counter for posts array.

Custom Context Provider - Ditch Prop Drilling

Passing program everywhere? Nah. Make a SolanaContext.jsx. Like this:

jsx import React, { createContext, useContext, useEffect, useState } from 'react'; import { Connection, clusterApiUrl } from '@solana/web3.js'; const SolanaContext = createContext(); export const useSolana = () => useContext(SolanaContext); export const SolanaProvider = ({ children }) => { const [connection, setConnection] = useState(null); const [wallet, setWallet] = useState(null); useEffect(() => { const conn = new Connection(clusterApiUrl('devnet')); setConnection(conn); }, []); return ( {children} ); };

Wrap App.js with it. Now any component: const { connection, wallet } = useSolana();. Clean. No globals. In 2026, everyone's using this for multi wallet support too - add Backpack, Brave.

Issue? Context updates lag. Fix: useEffect on wallet change to refetch program state. I usually debounce fetches at 500ms.

Top 5 Components Compared - Pick Your Stack

Component Use Case Install Size Tx Fee Example Gotchas
WalletMultiButton Connect any wallet Tiny 0 SOL (UI only) Styles must import
useSolanaSigner (Account Kit) Smart wallets Medium ~0.000005 SOL Loading states
Program (Anchor) Smart contract calls Small 0.00001 SOL avg IDL copy script
SolanaProvider (Custom) App wide state None N/A Missing deps crash
CounterState Read PDA state Tiny 0 SOL (read) Fetch errors on invalid

Why table? Visual. See WalletMultiButton wins for speed. But Anchor Program for real apps. Mix 'em.

BlogPost Component - CRUD on Solana

Want dynamic? Build a BlogPost.jsx. Needs user init first. Rust side: add initialize_user instruction. Frontend:

  • Fetch posts: program.account.posts.fetchAll() - wait, custom. Map PDAs.
  • Create: program.rpc.createPost({ title: 'Yo', content: 'Solana rocks' })
  • Modal toggle with showModal state.

Posts array empty? Map makes zero articles. Add one, posts.map(post => <Article={post.id}>{post.title}</Article>). Router it: dashboard for list, /post/:id for single. React Router NPM install, done.

Honestly, avatar uploads? Base64 to instruction data. Fees spike to 0.0001 SOL for big ones. Compress first.

Steps to Full Blog DApp

  1. npx create react app solana blog
  2. Install wallet adapter + anchor + web3.js
  3. Anchor init anchor init solana blog
  4. Build program, copy IDL
  5. Add routes: Dashboard, PostForm modal
  6. Context for posts state
  7. Test: anchor test, npm start

Stuck on "no posts"? Check posts provider has data. Console.log everything.

IncrementButton & State Readers - Reusable Bits

Break out buttons. IncrementButton.tsx:

tsx import { useConnection, useWallet } from '@solana/wallet adapter react'; import { program } from './anchor/setup'; // Your program export const IncrementButton = ({ accountPubkey }) => { const { connection, publicKey } = useConnection(), wallet = useWallet(); const increment = async () => { await program.methods.increment().accounts({ baseAccount: accountPubkey }).rpc(); }; return ; };

TypeScript? Yeah, 2026 standard. Add npm i -D @types/node. Readers like CounterState: useEffect fetch on mount, display {count}.

Pro tip: Toast notifications. NPM react hot toast. toast.success('Counter up!'). UX jumps.

Mobile Wallet Adapter - React Native Twist

Thinking Android? MobileWalletAdapter from Solana docs. Expo + React Native. Install @solana mobile/mobile wallet adapter protocol web3js. Similar hooks: useSolanaSigner spits address. Send tx same way. Fees identical.

But desktop first. Native apps lag behind web speed.

Troubleshooting - What I Wish I Knew

Tx rejected? 90% payer lacks SOL. Airdrop.

Program not found? Deploy: anchor deploy, update IDL address.

React crash on refresh? Persist baseAccount pubkey in localStorage. useEffect(() => { if (!localStorage.getItem('baseAccount')) generateNew(); }, []);

Devnet slow? QuickNode endpoint, free tier 25 req/s. Swap clusterApiUrl('devnet') for theirs.

Why bother? Solana tx 100x cheaper than ETH. 50k TPS. Your dApp flies.

Next Level: Voting DApp Components

Scale to voting. Redux for candidates state? Nah, Zustand lighter. Components: CandidateList, VoteButton. Fetch all: loop PDAs or global account. Serialize with Borsh. Vote: check user voted flag, rpc.vote(candidateId).

Deploy devnet: anchor deploy --provider.cluster devnet. 0.1 SOL rent. Register candidates same flow.
