Set up your own TON Wallet on The Open Network.
TON Wallet is an extension for accessing TON (The Open Network) enabled distributed applications, or "Dapps" in your normal Chrome browser!
TON Wallet also lets the user create and manage their own identities, so when a Dapp wants to perform a transaction and write to the blockchain, the user gets a secure interface to review the transaction, before approving or rejecting it.
Because it adds functionality to the normal browser context, TON Wallet requires the permission to read and write to any webpage. You can always view the source code on Github:
