CryptoCart Token - Smart Contract Audit Report

Summary

CryptoCart Token Audit Report CryptoCart is a new project on the Ethereum blockchain which intends to build an e-commerce platform.

For this audit we reviewed the project's token contract, deployed at 0x9e547061a345015869d26c7b6ee4ab5b63424441 on the Ethereum mainnet.

Notes of the Token Contract:
  • The total supply of the token is 1 million.
  • No minting functions are present, though any user may burn their own tokens to decrease the total supply.
  • Currently, 33% of the supply is locked and will vest to the team. Tokens unlock in 1 month and 2 months.
  • 8.3% of the supply is held in the liquidity pool.
  • 99% of liquidity is locked for 6 months.
  • The next largest holder has 3.1% of the supply.
  • No ownership-restricted functions are present.
  • The contract utilizes SafeMath to prevent overflow issues.
Audit Findings Summary:
  • No issues from external attackers were identified.
  • Ensure trust in the team as they will be vested a large number of tokens.
  • Date: April 26th, 2021.
