๐ How to Use WalletConnect Beginner's Guide
In under a minute you can link your wallet to an app, do what you came to do, and cleanly disconnect.
WalletConnect is the bridge most Web3 apps use to talk to your wallet. It is an open protocol, not a wallet and not a coin, so you never type your private key or seed phrase into a website. You connect by scanning a QR code or tapping a link, and your wallet stays in charge of every signature. Here is the whole flow, step by step.
-
1Open the dApp's official site and check the URL
-
2Click "Connect Wallet" and choose WalletConnect
The Connect Wallet button usually sits in the top right corner. Click it and a list of wallet options opens; pick WalletConnect.
-
3A QR code appears
The site shows a QR code that holds the session data for this one connection. Nothing private is in it; it just tells your wallet which app is asking to connect.
-
4Scan the QR code with your mobile wallet
Open your wallet app, such as Trust Wallet, tap its WalletConnect or scan icon, and point it at the QR code.
If the dApp is already open on the same phone, tap the WalletConnect deep link or paste the copied connection link into your wallet instead of scanning.
-
5Review the connection request
Your wallet now shows a request to read before you agree to anything. Check three things: the dApp name, the chains it wants, and the permissions or methods it is asking for.
-
6Approve only if the details are correct
If the app name matches the site you opened and you trust it, tap Approve. If anything looks off, reject it; nothing happens until you say yes.
-
7You are connected, so read every signing prompt
The app can now see your address, but it cannot move your funds on its own. Every transaction still pops up a separate signing prompt in your wallet, so read each one before you confirm.
-
8Disconnect the dApp when you are finished
Open your wallet's Connected apps or sessions screen and disconnect the dApp. Leaving old sessions open is clutter you do not need.
โ ๏ธ Stay safe
The protocol itself is generally safe; most losses come from connecting to a fake app and then approving a bad transaction. Check Point Research has documented drainer apps that lure people into scanning a malicious QR and signing requests that empty the wallet. A few habits keep you out of that trap.
- ๐ Never type your seed phrase into any site; a real WalletConnect link never asks for it.
- ๐งพ Read each signing prompt; an unlimited token approval can let a contract move your coins later.
- ๐ฃ Treat surprise pop-ups and lookalike URLs as phishing until you have checked them.
- ๐ช Remember connecting is free; only on-chain actions cost a gas fee in the chain's native coin.
- ๐งช New to an app? Try a small amount first so a mistake stays cheap.
โ FAQ
- Is WalletConnect a wallet or a token I need to buy?
- Neither. It is an open protocol that links a wallet you already have to a dApp. You do not buy anything to use it, and connecting itself is free; only the blockchain transactions you later sign cost gas.
- Does WalletConnect ever need my seed phrase?
- No. A real WalletConnect connection never asks for your 12 to 24 word recovery phrase or private key. Anyone asking you to type those words into a site or chat is a scammer, so close the page.
- Is disconnecting the same as making my funds safe?
- Not quite. Disconnecting only stops the site from seeing your address. Any token approvals you already signed stay active, so to fully cut a risky app off you also revoke those approvals with a tool like revoke.cash.
- Can one connection cover several blockchains?
- Yes. WalletConnect v2 supports multi-chain sessions, so one connection can cover networks like Ethereum, Polygon, BNB Smart Chain, and Solana without reconnecting for each chain.
