⭐Smart Contract

Contract Description

Contract Address:

BNB Chain: 0x0000000000000000000000000000000000001000

Ethereum: 0x0000000000000000000000000000000000001000

Developed with Secure OpenZeppelin Library: The contract is developed using the secure OpenZeppelin library.

User Token Authorization: Users authorize their tokens to the contract. The agent continuously monitors token prices. When the token price drops, the contract swiftly sells the tokens to ensure the safety of users' assets.

Trusted Token Exchange: This smart contract provides a more trustworthy way to exchange tokens. It executes token swap operations and charges fees through digital signature authorization. By incorporating digital signature authorization and fee mechanisms, this contract offers a more reliable method for token exchanges. It reduces the risk of fraudulent withdrawals, encourages legitimate users of the contract, and provides economic support for the contract's sustainability. This helps minimize potential harm to users and investors from fraudulent activities such as Rug Pulls.

Key Components and Concepts

Fee: A portion of tokens from each transaction is collected as a fee.

Signature Verification: User requests to execute token swap operations are verified through digital signatures to ensure the operation is authorized by a specific user.

Event Logging: The contract uses txLog to record detailed information for each transaction, including sender address, user address, fee address, token addresses, exchange quantities, and fee amounts.

Token Exchange Execution Functions:

• Signature Verification:

• Verify user signatures to ensure operations are authorized by users.

• Token Swap:

• Execute token swap operations, converting a specified quantity of one token into another.

• Fee Collection:

• Based on the fee percentage, a portion of tokens is transferred as a fee to the fee address.

• User Profits:

• The remaining tokens are transferred to the user as their exchange profit.

Open Source Code

Permission Control:

In this section of the code, permission validation is implemented using recoverV4.

Transaction Execution:

Currently, the code supports both Uniswap V2 and V3 versions. Different swap operations are performed based on the user's selection.

Withdrawal - Prevention of Mistaken Deposits

To prevent users from accidentally depositing assets into the contract, a withdraw method has been added to the contract. This method allows users to retrieve assets that have been mistakenly deposited into the contract.

Risk Warning

Exercise caution when interacting with smart contracts or blockchain applications. Despite extensive auditing, smart contracts still carry vulnerability risks. Always research the credibility of a dApp or smart contract before interacting with it.

Potential risks include:

Rug Pulls via Private MemPool/Flashbots RPC:

● Attacks occurring through private mempool/Flashbots RPC where attackers steal tokens deposited by users into the protocol.

Protocol-Level Attacks:

● Attacks at the protocol level where attackers exploit vulnerabilities, stealing tokens deposited by users into the protocol.

Use of Untrusted Networks:

● Risks associated with adding untrusted networks to your interactions.

Transactions Queued Behind Rug Pull Transactions:

● Transactions initiated by the program being packed into blocks after Rug Pull transactions, leading to potential vulnerabilities.

Always exercise due diligence and stay updated with the latest security practices when engaging with smart contracts and blockchain applications.
