OmniTensor Smart Contract Audit

Summary

This Solidity code defines a smart contract named `OmniTensor`, which implements the ERC20 token standard with additional functionalities, including owner-based controls, token trading via Uniswap, and tax mechanisms. Here is an overview of its components: Key Features: ERC20 Token Basics: The contract implements the standard ERC20 interface (`IERC20`), providing methods such as `balanceOf`, `transfer`, `approve`, and `transferFrom`. The token is named “OmniTensor” (`OMNIT`) with 18 decimals and a total supply of 1 billion tokens. Ownership Control: The `Ownable` contract provides functionality for managing ownership, including transferring ownership or renouncing it. The owner has exclusive rights to modify certain contract behavior. Uniswap Integration: The contract interacts with the Uniswap V2 protocol via `IUniswapV2Factory` and `IUniswapV2Router02` interfaces. It allows adding liquidity in ETH and enables token swaps through the DEX. The `startTrading` function activates trading by creating a Uniswap pair and adding liquidity. Taxation Mechanism: A buy/sell fee (initially set to 5%) is applied to transactions involving Uniswap. The tax amount is deducted from transfers, except for addresses that are marked as excluded. The contract collects the tax in tokens, which can later be swapped for ETH and distributed to various wallets (`OmegaWallet`, `GammaWallet`, `BetaWallet`, `AlphaWallet`). Limits and Controls: The contract enforces limits on transaction size (`maxTxValue`) and wallet holdings (`maxWalletHoldings`). Trading can be paused and started by the owner. Additionally, the contract provides the ability to remove transaction and wallet limits. Emergency Functions: The owner can withdraw accumulated ETH or recover any remaining tokens in the contract. Manual token swaps for ETH can also be triggered by the owner. This contract is designed with a flexible fee structure, controlled trading features, and strong ownership functionality, making it well-suited for projects aiming to integrate liquidity and token swapping through Uniswap.
