What is WalletConnect and how does it work?

Created by Ethos Support, Modified on Fri, 24 May 2024 at 11:33 AM by Ethos Support

WalletConnect is an open-source protocol that facilitates communication and interaction between decentralized applications (DApps) and cryptocurrency wallets. It allows users to securely connect their wallets to DApps running in web browsers or mobile applications, enabling seamless and decentralized access to blockchain-based services, such as decentralized exchanges, lending platforms, and games.


Here's how WalletConnect works:


QR Code Scanning or Deep Linking: To establish a connection between a wallet and a DApp, the user typically scans a QR code displayed by the DApp using their cryptocurrency wallet application. Alternatively, some wallets support deep linking, where users can click on a link to initiate the connection process.

Session Establishment: Once the QR code is scanned or the deep link is clicked, the wallet and the DApp establish a secure communication session using end-to-end encryption. This session is established through a relay server, which helps facilitate the initial connection between the two parties.

Authorization and Confirmation: The user is prompted to authorize the connection between their wallet and the DApp, typically by confirming the connection request on their wallet application. This authorization ensures that the user maintains control over their funds and data throughout the interaction.

Data Transmission: With the connection established, the DApp can request information or perform actions on behalf of the user, such as querying wallet balances, executing transactions, or interacting with smart contracts on the blockchain.

Decentralized and Secure: WalletConnect operates on a decentralized network of relay servers, ensuring that user data and transactions remain private and secure. The protocol uses cryptographic techniques to protect the integrity and confidentiality of communications between wallets and DApps.

WalletConnect offers several benefits:


Convenience: Users can access decentralized services directly from their wallets without the need to manually import private keys or manage separate accounts for each DApp.

Security: WalletConnect leverages end-to-end encryption and user-controlled authorization to ensure that interactions between wallets and DApps are secure and tamper-proof.

Interoperability: WalletConnect is compatible with a wide range of cryptocurrency wallets and DApps, allowing users to access decentralized services across different platforms and ecosystems.

Trustless: WalletConnect operates in a trustless manner, meaning that users retain full control over their private keys and funds throughout the interaction with DApps.

Overall, WalletConnect plays a crucial role in enabling seamless and decentralized access to blockchain-based services, fostering greater adoption and usability of decentralized applications and cryptocurrencies.
