Minter Wallet in your Browser
Minter Link is an extension for accessing Minter enabled distributed applications, or "Dapps" in your browser!
Minter Link also lets the user create and manage multiple Minter wallets, 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, Minter Link requires the permission to read and write to any webpage. You can always "view the source" of Minter Link the way you do any Chrome extension, or view the source code on Github:
