Wrapped Ton Coin Smart Contract Audit
Summary
TON is a decentralized and open network, created by the community using a technology designed by Telegram. This Solidity code defines a bridge contract that facilitates the transfer of tokens between the Ethereum and TON (Telegram Open Network) networks. Let’s break down the key components and functionalities of the contract: Here’s a brief overview of the key components and functionalities of the provided code: Interfaces: The TonUtils interface defines structs for TON addresses and transactions, as well as a struct for signature data. The IERC20 interface defines the standard ERC20 token functions. ERC20 Token: The ERC20 contract implements the standard ERC20 token functionality with functions for transferring tokens, managing allowances, and emitting events. Bridge Interface: The BridgeInterface interface extends TonUtils and declares functions for voting on various actions such as minting tokens, updating the set of oracles, and switching burn status. Signature Checker: The SignatureChecker contract provides functions for verifying ECDSA signatures and generating unique IDs for different types of actions. Wrapped TON: The WrappedTON contract extends ERC20 and TonUtils, adding additional functionalities for minting and burning tokens, specifically for interactions with the TON network. Bridge: The Bridge contract inherits from SignatureChecker and WrappedTON, implementing the bridge functionality. It maintains a set of oracles, allows for voting on different actions, and executes the actions based on the received votes. The contract is without any other custom functionality and without any ownership control, which makes it truly decentralized. Overall, the code aims to provide a decentralized bridge between Ethereum and TON networks, allowing for token swaps and governance through a voting mechanism involving a set of oracles.
