TronLink is firstly launched at TRON's official website and backed by TRON foundation, TronLink is the TRON wallet with the most users,coming in three versions (Chrome Wallet Extension/iOS/Android), and you're looking at the Chrome Wallet Extension for TRON.
It is developed to deeply integrate with the TRON network, ensuring that users have full access to the blockchain's features, including staking mechanisms. TronLink accommodates various Web3 use cases, functioning as a gateway for users to interact with decentralized applications (DApps) on the TRON blockchain.
As of my last knowledge update in September 2021, TronLink Pro was considered a legitimate cryptocurrency wallet and browser extension designed for the TRON blockchain. It allowed users to manage their TRX (TRON's native cryptocurrency) and interact with decentralized applications (DApps) on the TRON network.
