Migrate from @metamask/sdk to @metamask/connect-evm, @metamask/connect-multichain, and @metamask/connect-solana with step-by-step package, API, and configuration changes

Build and send a Solana transaction using MetaMask Connect. Covers both the React wallet-adapter approach (sendTransaction) and the vanilla browser approach (signAndSendTransaction wallet-standard feature).

Scaffold a vanilla JS/TS browser app with MetaMask EVM integration using createEVMClient, EIP-1193 provider event listeners, RPC methods, and chain switching with chainConfiguration fallback

Scaffold a React app with MetaMask EVM integration using createEVMClient, useState/useEffect/useRef patterns, provider.request calls, chain switching, and error handling

Set up a multichain app using createMultichainClient from @metamask/connect-multichain. Covers EVM + Solana scopes, invokeMethod for both ecosystems, session events, headless mode, getInfuraRpcUrls, selective disconnect, and singleton behavior.

Set up a vanilla browser (non-React) app with @metamask/connect-solana using wallet-standard features directly. Use when integrating MetaMask Solana without a framework or wallet adapter library.

Set up a React app with @metamask/connect-solana and the Solana wallet adapter. Use when integrating MetaMask with Solana in React, configuring WalletProvider, or building connect/sign/send flows with useWallet.

Set up a React Native app with @metamask/connect-solana using polyfills and multichain invokeMethod for Solana operations. Use when building Solana support in React Native where wallet-adapter is not available.

Set up a React or React Native app with wagmi and a MetaMask connector implementation that matches your installed @metamask/connect-evm version. Use when integrating MetaMask with wagmi, configuring the metaMask() connector, or building connect/sign/send flows.

Sign and send Solana transactions using the multichain client's invokeMethod. Covers signTransaction, signAndSendTransaction, signMessage, building transactions with @solana/web3.js, base64 encoding, mainnet/devnet scopes, and selective disconnect.

Sign an arbitrary message on Solana using MetaMask Connect. Covers both the React wallet-adapter approach (useWallet) and the vanilla browser approach (wallet-standard features).

Diagnose and fix common MetaMask Connect SDK connection failures, transport issues, and runtime errors

Migrate a wagmi app from @metamask/sdk to the new @metamask/connect-evm connector (wagmi PR

Send ETH and contract transactions with MetaMask using eth_sendTransaction via the EIP-1193 provider, gas estimation, receipt polling, and the connectWith shortcut

Scaffold a React Native app with MetaMask EVM integration including required polyfills, metro.config.js shims, import order constraints, mobile deeplinks, and a full component example

Set up a wagmi app with the MetaMask Connect EVM connector using @metamask/connect-evm

Sign messages with MetaMask using personal_sign and eth_signTypedData_v4 via the EIP-1193 provider, plus the connectAndSign shortcut

Sign and send EVM transactions using the multichain client's invokeMethod. Covers eth_sendTransaction, personal_sign, eth_signTypedData_v4, scope selection, and RPC routing for read vs sign operations.
