DeWallet is a Chrome extension developed by DeLab that allows users to access TON enabled decentralized applications, or "dApps," directly from their browser. This extension injects the ton web3 API into every website's javascript context, enabling dApps to read data from the blockchain.

One of the key features of DeWallet is the ability for users to create and manage their own identities using private keys stored in a local client wallet. When a dApp requires a transaction to be performed and written to the blockchain, DeWallet provides a secure interface for users to review and approve or reject the transaction.

DeWallet also supports various network features, including Jettons, NFT, TON DNS, and more. However, it's important to note that due to the added functionality it brings to the browser context, DeWallet requires the necessary permissions to read and write to any webpage.
