 With the USDT release on TON, an advanced version of the Jetton contract was developed. This version introduces many new TVM gas assertion techniques, as well as extended functionality. Since USDT is a centralized asset, there are specific requirements and restrictions for its operations. More specifically, there is no _burn_ opcode, which means that formally, the Governance contract is not TEP-compliant, as Jetton burn functionality is part of the standard. Also, the Minter contract includes a _governance_ mechanism that allows users to perform any actions on other Jetton Wallets.
 
-Another noticeable advantage of this implementation is extensive testing. All previous versions didn't test edge cases of config changes that will affect storage / forward fees. This test suite became the foundation for all future Jetton versions.

 Plugins enable developers to implement custom logic that integrates with wallet functionality. When a plugin is installed on a wallet through a signed transaction, it can force wallet to send internal message with predefined opcode (`0xf06c7567`) and any available Toncoin amount to specified addresses. Plugins are separate smart contracts that can implement their own custom logic.

 Plugins are essentially other smart contracts on TON that developers are free to implement as they wish. In relation to the wallet, they are simply addresses of smart contracts stored in a dictionary in the wallet's persistent memory. These plugins are allowed to request funds and remove themselves from the "allowed list" by sending internal messages to the wallet.
