🔐 What is WalletConnect?
WalletConnect is an open-source protocol that establishes an encrypted connection between your wallet and a dApp (like Uniswap or OpenSea) without sharing your private keys. Unlike browser extensions (e.g., MetaMask), it:
- Does not store keys in your browser (reduces malware risks).
- Requires manual session approval (no auto-connections).
- Works across devices (mobile ↔ desktop).
Why Use WalletConnect with Ledger Live?
- Your keys stay offline in your Ledger device.
- Every transaction must be verified on your hardware wallet.
- No phishing risks from fake browser extensions.
📲 How to Connect Ledger Live to WalletConnect
Step 1: Update Ledger Live & Firmware
- Ensure you have the latest Ledger Live version (Settings > Help > Check for updates).
- Update your Ledger Nano S/X firmware via Ledger Live Manager.
Step 2: Open WalletConnect in Ledger Live
- Go to “Discover” > “WalletConnect”.
- Click “New Connection”.
- A QR code scanner will appear.
Step 3: Connect to a dApp
- On the dApp (e.g., Uniswap, OpenSea), select “WalletConnect” as the wallet option.
- Scan the QR code with Ledger Live’s scanner.
- Choose your Ethereum account (or other supported blockchain).
- Approve the connection on your Ledger device.
Step 4: Verify & Sign Transactions
- When performing actions (swaps, NFT purchases), check details on your Ledger screen before approving.
⚠️ Security Best Practices
✔ Only connect to trusted dApps (bookmark official sites like app.uniswap.org).
