Contracts Tab

The Contract tab allows users to inspect the smart contract source code, read functions, and interact with the token’s smart contract. It is particularly useful for developers, security analysts, and users who want to verify whether the contract is safe, transparent, and follows standard practices.

• Contract Information This section provides important details about the smart contract, including its compiler version, EVM version, and optimization settings.

  • Contract Name: The contract is named "MyToken", which is the official name of the token’s smart contract on the blockchain.

  • EVM Version: The contract runs on the "London EVM" version. EVM versions affect how smart contracts execute transactions and handle gas fees.

  • Optimization Runs: The contract was optimized with "200" runs before deployment.

  • Compiler Version: The contract was compiled using "Solidity v0.8.26+commit.8a97fa7a". Different Solidity versions have specific security fixes and improvements.

  • Optimization Enabled: False (Optimization is Disabled). This means that the contract was deployed without gas optimizations, making it potentially more expensive to interact with.

  • Contract Source Code Type: The contract source code is stored in "solidity-standard-json-input" format. This format is used for structured contract compilation and debugging. It allows developers to easily analyze the code and verify its functions.

• Contract Source Code Below, we see a partial view of the contract’s source code, which is written in Solidity (the most widely used smart contract programming language).

• The displayed code includes a function named toInt248(int256 value), which is responsible for downcasting an integer from 256 bits to 248 bits.

• What does this function do?

  • It ensures that the input number fits within 248 bits before storing or using it.

  • If the input is too large or doesn’t match the expected downcast value, the function triggers a revert error, preventing the contract from continuing execution.

  • This type of function is used to reduce storage costs and improve efficiency.

• Why does this matter?

  • If a contract has incorrect type conversions, it can lead to overflow/underflow bugs, potentially breaking the token's functionality.

  • Ensuring safe type conversions helps prevent security vulnerabilities and loss of funds.

The full source code can be inspected further to check for other important functions like minting, burning, transfers, and access control.

Is the Contract a Proxy?

On the right side, there is a blue button labeled "Is Proxy?".

• What is a Proxy Contract?

  • Some tokens use a proxy contract architecture, which allows the contract logic to be upgraded in the future without changing the contract address.

  • This means the token owner can modify its behavior even after deployment.

• Why is this important?

  • Non-proxy contracts are more secure because their logic cannot be changed after deployment.

  • Proxy contracts can be risky if the owner can upgrade them to add malicious functions, such as stealing user funds or minting unlimited tokens.

  • If this contract is a proxy, users should carefully check who controls it and whether ownership is renounced.

If users want full transparency and security, they should avoid interacting with proxy contracts unless they trust the project team.
