Before we get started, here are the usual entry points: the Binance Official Site, the Official Binance App, and the iOS installation guide. WalletConnect is an open protocol that connects Web3 wallets to decentralized applications (DApps). Launched in 2018 by Pedro Gomes, it has since become the de facto standard connection protocol across crypto. As of April 2026, WalletConnect is integrated with 600+ wallets and 65,000+ DApps, with more than 150 million cumulative connections (source: WalletConnect official data).

How WalletConnect Works

The core problem WalletConnect solves is this: when a user is on a DApp in a desktop browser, how do they sign safely using a mobile wallet? Early solutions involved importing a private key into a desktop browser extension, which exposed the key to real security risk. WalletConnect instead uses an encrypted communication channel, letting the DApp request a signature while the wallet approves it remotely, keeping the connection secure.

A simplified description of the WalletConnect flow:

  1. The DApp generates a session QR code: it contains a session identifier
  2. The user scans the code: the mobile wallet recognizes the QR code and initiates a connection request
  3. An encrypted channel is established: the DApp and wallet exchange public keys through WalletConnect's relay service
  4. The user confirms the connection in their wallet
  5. The session is established: when the DApp requests a signature, the wallet pops up a prompt for the user to approve
  6. The signature is returned: once the user approves, the wallet sends the signature result back to the DApp

The table below compares WalletConnect v1 (deprecated) with v2:

Dimension WalletConnect v1 WalletConnect v2
Multi-chain support Single-chain sessions only Multiple chains in a single session
Concurrent sessions One connection at a time Multiple DApps connected simultaneously
Offline messaging Not supported Supported
Protocol design JSON-RPC over WebSocket Modular, multi-chain
Current status No longer supported Current version

WalletConnect v2 has been the only supported version since mid-2023, with the v1 protocol formally shut down in June 2023.

How to Connect a DApp Using WalletConnect

Desktop DApp + Mobile Wallet Mode

The most common scenario: a user visits a DApp (like Uniswap or OpenSea) in a desktop browser and signs using a mobile wallet by scanning a QR code.

The steps:

  1. Open the DApp in a desktop browser (for example, https://app.uniswap.org)
  2. Click "Connect Wallet" in the top-right corner
  3. Select "WalletConnect"
  4. A QR code screen pops up
  5. Open your wallet app on your phone (MetaMask, OKX Wallet, Trust Wallet, etc.)
  6. Find the "scan QR code" or "connect to DApp" feature
  7. Scan the QR code shown on the desktop screen
  8. Tap "Connect" in the mobile wallet
  9. The desktop DApp automatically recognizes that the connection succeeded

Afterward, whenever you take an action in the DApp (like swapping a token or buying an NFT), your phone will pop up a signature request, and the transaction only broadcasts on-chain once you approve it in your wallet.

In-App Connections on Mobile

Mobile users also use WalletConnect inside DApp apps (like Aave or the OpenSea app):

  1. The DApp app pops up a wallet selection list
  2. Tap the wallet you want to use
  3. The system switches to that wallet's app
  4. The wallet shows a connection request
  5. Once the user confirms, they're switched back to the DApp with the connection complete

Essentially every major wallet supports WalletConnect v2, making it the foundational connection layer of the Web3 wallet ecosystem.

WalletConnect's Security Design

WalletConnect's security architecture:

Mechanism Purpose
End-to-end encryption Only the DApp and wallet can decrypt the messages between them
Session keys Each connection generates an independent session key that is never reused
Relay server can't see contents WalletConnect's relay server only forwards encrypted packets
User sovereignty The wallet has final say on signing; the DApp cannot force a signature
Domain verification Some wallets show the DApp's domain so users can double-check it
Session expiry Sessions have an expiration and disconnect periodically

Core security principle: the WalletConnect protocol itself is secure — the real risk comes from users' judgment about what they're actually signing. Every signature requires explicit approval in the wallet; a wallet never signs automatically.

Common Risks When Connecting to DApps via WalletConnect, and How to Avoid Them

Risk 1: Phishing DApps

The most common risk: users visit a fake DApp (for example, unisvvap.org impersonating uniswap.org), scan the code to connect, and get tricked into signing a malicious transaction.

How to protect yourself:

Risk 2: Blind Signing Traps

A malicious DApp gets a user to sign "unreadable" binary data that is actually a transfer or approval action.

How to protect yourself:

Risk 3: Unlimited Approvals

ERC-20 token approvals default to an "unlimited" amount, meaning the approved contract can move any quantity of that token out of your account.

How to protect yourself:

Risk 4: Wrong Chain or Wrong Address

Some DApps direct users to sign on the wrong chain or against the wrong contract address.

WalletConnect's Protocol Token: WCT

In 2024, WalletConnect launched its native protocol token, WCT (WalletConnect Token), used to pay network fees, incentivize node operators, and enable governance participation.

Parameter Detail
Token symbol WCT
Total supply 1 billion
Launch date November 2024
Main use Node operator incentives + protocol governance
Network Optimism + Solana

WCT is currently listed on exchanges including OKX, Bybit, and Coinbase, but using the WalletConnect protocol itself remains free for regular users — WCT primarily matters to node operators and large-scale integrators.

WalletConnect FAQ

Q: Is WalletConnect safe? The protocol itself is secure: end-to-end encryption, the user holds final decision-making authority, and the relay server can't see the contents of any message. The real risk comes from a user's judgment about whether a given DApp is legitimate and what a signature request actually does.

Q: Can a DApp move my funds just because I scanned a code to connect? No. WalletConnect only sets up a "communication channel" — any transaction the DApp initiates still requires the user to confirm it in their wallet. Without a user's signature, a DApp can't touch their funds.

Q: Does a DApp keep tracking me forever after I've connected? No. Once a session expires or the user disconnects manually, the DApp loses the ability to request signatures. A DApp may still log a user's wallet address for analytics purposes — on-chain addresses are inherently public, so this doesn't require any active tracking by the DApp.

Q: How do I disconnect from WalletConnect? Find the session under "Connected DApps" in your wallet and tap "Disconnect." You can also just let the session expire naturally (usually within a few hours to a few days).

Q: Does WalletConnect charge fees? It's free for regular users. On-chain transactions still require gas (paid to blockchain miners/validators, unrelated to WalletConnect).

Q: What's the difference between WalletConnect and the MetaMask browser extension? The MetaMask extension is a wallet that lives inside your browser, with the private key stored there; WalletConnect is a protocol that lets an external wallet (mobile or hardware) connect to a DApp. In terms of security, WalletConnect plus a hardware wallet beats the MetaMask extension.

Q: Can a hardware wallet use WalletConnect? Yes. Ledger Live, Trezor, and others all support WalletConnect. This is the most recommended connection method for larger holders — hardware-based signing bridged through WalletConnect.

Q: Will WalletConnect eventually be phased out? Not any time soon. WalletConnect is already the de facto standard, integrated into nearly every major wallet and DApp. It may eventually be partly displaced by newer approaches like ERC-4337 smart contract wallets, but WalletConnect will likely remain in wide use for a long time to come.

Q: Do I need to hold the WCT token? No, not for regular users. WCT mainly serves node operators and high-frequency integrators — using the WalletConnect protocol itself doesn't require holding WCT.

Q: What should I do if I see "unknown DApp source" when connecting my wallet? Cancel the connection immediately. This usually indicates a phishing DApp or a hijacked link. Verify the domain carefully before reconnecting — never try to force a connection past that warning.

Q: Should I be cautious about every signature request? Yes. Anything you approve in your wallet can have real on-chain consequences, including transfers, approvals, and contract calls. Making a habit of reading exactly what you're signing before you sign it is the single most important security habit to build.
