+Wallet-cli now supports GasFree features, allowing users to perform token transfers without paying gas fees directly. For more detail, please check the [GasFree](#GasFree-Support) section below.
+
+The underlying implementation of all Wallet-cli gRPC APIs has all migrated to the [Trident APIs](https://github.com/tronprotocol/trident). The migration represents a significant architectural shift. This strategic move consolidates the underlying implementation of the Wallet-cli's remote procedure calls, standardizing them under the robust and optimized Trident API framework. This unification not only streamlines development and maintenance efforts but also enhances the overall reliability, performance, and scalability of the Wallet-cli. The Trident APIs, known for their efficiency and comprehensive capabilities, now serve as the sole foundation for all gRPC interactions within the Wallet-cli, ensuring a consistent and high-quality experience for users and developers alike.

 Wallet-cli connect to java-tron via gRPC protocol, which can be deployed locally or remotely. Check **Run a web Wallet** section.
 We can configure java-tron node IP and port in ``src/main/resources/config.conf``, so that wallet-cli server can successfully talk to java-tron nodes.
+Besides that, you can simply use `SwitchNetwork` command to switch among the mainnet, testnets(Nile and Shasta) and custom networks. Please refer to the Switch Network section.
