Project Background

Website Details

• Olas incentivizes and coordinates different parties to launch autonomous agents that form entire AI economies.
• Olas is a network focused on creating and deploying autonomous AI agents across multiple blockchains. 
• It enables participants to co-own and benefit from AI economies. The platform uses the Olas Protocol to coordinate and incentivize various actors, while the Olas Stack allows developers to build robust, transparent agents. 
• These agents operate autonomously, supporting applications in Web3 and beyond.

Code Details

This Solidity code defines an ERC20 token that is mintable and burnable via a bridge contract, specifically designed to work with the Optimism Layer 2 solution. Here’s an overview of the key components and functionalities:

Core Contract:

• Semver: Handles semantic versioning with `MAJOR_VERSION`, `MINOR_VERSION`, and `PATCH_VERSION`.

• ERC20:

• • Implements the standard ERC20 functionality with additional internal functions to handle minting, burning, allowances, and token transfers.
  • Functions include `name`, `symbol`, `decimals`, `totalSupply`, `balanceOf`, `transfer`, `allowance`, `approve`, `transferFrom`, `increaseAllowance`, `decreaseAllowance`, `_transfer`, `_mint`, `_burn`, `_approve`, `_spendAllowance`, `_beforeTokenTransfer`, and `_afterTokenTransfer`.

• OptimismMintableERC20:

• • Extends `ERC20` and `Semver` to create a mintable and burnable token for use with the Optimism bridge.
  • The constructor takes parameters for the bridge address, remote token address, token name, and symbol.
  • The `mint` and `burn` functions can only be called by the bridge contract.
  • Implements `supportsInterface` for interface detection.

This structure ensures that the token adheres to the ERC20 standard while adding the necessary functionalities for integration with the Optimism Layer 2 solution, specifically for minting and burning tokens via a designated bridge contract.

Audit Summary

• We observed 2 Informational issues in the smart contracts. but those are not critical.
• The security state of the reviewed smart contract, based on standard audit procedure scope, is “Secured”.

Executive Audit Summary

• According to the standard audit assessment, the Customer`s solidity smart contracts are “Secured”. This token contract does not have any ownership control, hence it is 100% decentralized.
  
• We used various tools like Slither, Solhint and Remix IDE. At the same time this finding is based on critical analysis of the manual audit.
