Overview
WalletConnect is an open-source Web3 communications protocol that links wallets to dApps and other wallets securely, without exposing private keys.
It supports 100+ wallets and thousands of decentralized applications across EVM and non-EVM chains. Instead of copy-pasting seed phrases or manually importing private keys, users connect via QR codes or deep links—making onboarding simpler and safer.
Beyond just “connect wallet,” WalletConnect is evolving into a full messaging, transaction, and cross-app communication layer for Web3.
Picture a universal translator - but for crypto wallets. It speaks the language of every chain, every dApp, every signing request. For users, it feels like magic: scan a QR code, and you’re in. No extra browser extensions, no typing keys, no anxiety.
For developers, it’s like plugging into a global payment and identity socket—one SDK, infinite reach. It’s the invisible bridge that makes Web3 feel like Web2’s convenience, but without Web2’s trust problems.
Multi-Chain Support
Works with Ethereum, Solana, Cosmos, Near, Polkadot, and more, ensuring wide compatibility.
Session-Based Encryption
Uses symmetric encryption for all message payloads, ensuring private key isolation.
Versatile SDK
Offers JavaScript, Swift, Kotlin, and server-side SDKs for easy dApp and wallet integration.
Transaction & Messaging APIs
Enables signing transactions, verifying messages, and initiating dApp-to-wallet communication seamlessly.
Scalable Infra
WalletConnect Cloud handles relay server operations—developers can self-host for Sovereignty
Protocol Versioning
WalletConnect v2 introduced multi-chain sessions, improved relay performance, and better recovery mechanisms.
Developer Adoption
Integrated by major wallets like MetaMask, Trust Wallet, Rainbow, Argent, and exchanges like Coinbase Wallet.
Security Design
Private keys never leave the user’s wallet—session keys are ephemeral and isolated from transaction signing keys.
Ecosystem Growth
Now powers wallet-to-wallet messaging (WalletConnect Chat) and notification services for dApps.
Standards Alignment
Works with CAIP (Chain Agnostic Improvement Proposals) for chain identification and interoperability.
