How to Send Transactions in Your Next.js dApp with Wagmi โ 2026 BNB Chain Guide for Beginners
๐ Fresh off wallet integration? Let's level up: Add simple token transfers to your Next.js app using Wagmi hooks. Perfect for BNB Chain dApps, handle $BNB sends or ERC-20 tokens like a pro, tying into gasless trends for smoother UX.
Assumes you have Wagmi/RainbowKit setup from my last tutorial (check it if not!).
Quick Steps (Next.js 14+):
Install viem (already in deps? Skip):npm install viemCreate a transfer function (e.g., in a component):import { useAccount, useSendTransaction } from 'wagmi'import { parseEther } from 'viem'function SendBNB() { const { address } = useAccount() const { sendTransaction } = useSendTransaction() const handleSend = () => { sendTransaction({ to: '0xRecipientAddress', // Replace with test addr value: parseEther('0.001'), // 0.001 BNB }) } return <button onClick={handleSend} disabled={!address}>Send 0.001 BNB</button>}For ERC-20 (e.g., $BUSD on BNB Chain): Use useWriteContract instead:import { useWriteContract } from 'wagmi'import { parseUnits } from 'viem'import { erc20Abi } from 'viem/abi' // Or import standard ABIfunction SendToken() { const { writeContract } = useWriteContract() const handleSend = () => { writeContract({ address: '0xTokenContractAddr', // e.g., BUSD abi: erc20Abi, functionName: 'transfer', args: ['0xRecipient', parseUnits('1', 18)], // 1 token, 18 decimals }) } return <button onClick={handleSend}>Send Token</button>}
Pro Tip: Add error handling with useWaitForTransaction for confirmations. Test on BNB Testnet, grab faucet BNB via Binance tools!

How to Add Wallet Connect to Your Next.js App in 2026 โ Beginner Step-by-Step Guide
๐ Web3 devs & beginners: Tired of clunky wallet connections in your dApps? Here's a clean, modern way to integrate WalletConnect v2 into a Next.js project using Wagmi + RainbowKit โ perfect for BNB Chain or any EVM chain!
Why this matters in 2026:
Gasless txs & account abstraction are exploding (shoutout to projects like Zama for privacy layers).
Seamless wallet UX = more users actually trading/exploring on Binance Web3 Wallet or BNB Chain dApps.
$BNB ecosystem is heating up โ better integrations mean better adoption!
Quick Setup (React/Next.js 14+ App Router):
Install dependencies:npm install wagmi viem @tanstack/react-query @rainbow-me/rainbowkitCreate config (lib/wagmi.ts):import { createConfig, http } from 'wagmi'import { bnbSmartChain } from 'wagmi/chains'import { injected, walletConnect } from 'wagmi/connectors'export const config = createConfig({ chains: [bnbSmartChain], connectors: [ injected(), walletConnect({ projectId: 'YOUR_WALLETCONNECT_PROJECT_ID' }), // Get free from walletconnect.com ], transports: { [bnbSmartChain.id]: http() },})Wrap your app (app/layout.tsx):import { WagmiProvider } from 'wagmi'import { RainbowKitProvider } from '@rainbow-me/rainbowkit'import { config } from '@/lib/wagmi'import '@rainbow-me/rainbowkit/styles.css'export default function RootLayout({ children }) { return ( <html lang="en"> <body> <WagmiProvider config={config}> <RainbowKitProvider>{children}</RainbowKitProvider> </WagmiProvider> </body> </html> )}Add Connect Button anywhere:import { ConnectButton } from '@rainbow-me/rainbowkit'<ConnectButton />
Boom โ users can connect MetaMask, Trust Wallet, or Binance Web3 Wallet with one click! Test on BNB Testnet first.
Pro Tip: Add chain switching for $BNB trades directly in your dApp UI.
