OpenSea — Wallet Connection Guide

How to safely connect common Web3 wallets (MetaMask, WalletConnect, etc.) to OpenSea — informational only.

Overview

OpenSea connects to your crypto wallet (MetaMask, WalletConnect, Coinbase Wallet, etc.) to read your address and let you sign transactions (list, buy, sell). Your private keys stay in your wallet; OpenSea requests signatures when needed.

Connecting MetaMask (desktop)

  1. Open your browser with MetaMask installed and unlocked.
  2. On OpenSea, click the profile / connect-wallet option and choose MetaMask.
  3. Approve the connection popup from MetaMask; the site will see your public address only.
  4. When making actions (list, buy), approve signing requests in MetaMask — always read message text before confirming.
Tip: Use a dedicated browser profile for Web3 activity to reduce extension conflicts.

Connecting WalletConnect (mobile)

  1. Choose WalletConnect on OpenSea's connect flow — a QR code appears.
  2. Open a WalletConnect-compatible wallet app on your phone (e.g., Trust Wallet, Rainbow).
  3. Scan the QR code to pair; confirm the connection in your wallet app.
  4. Approve signing requests on your phone when required.
