Result Summary
Ethos‘ audit of the Coffee Beans smart contract has concluded with a PASSING result, meaning the contract is largely safe from external threats but users funds are at the mercy of the team’s decision related to the significant referral bonuses collected by the marketing wallet. The initial review identified a number of informational issues, and 2 medium-risk issues, most of which have since been resolved except for the ones reported below. The remaining report includes all issues identified in the initial review, as well as the revised status post resolution by the team if applicable.
- The smart contract is a variant of the ‘miner‘ meta, but not a fork of the typical miner codebase
- It allows users to deposit network native tokens into the contract which are locked on deposit and redistributed to users over time
- The rate of redistributions approximately 8% daily and varies based on the rate of increase of total value locked
- There is a referral bonus distributed to referrers of approximately 12.5%
- The marketing wallet does accumulate all the referrals where one is not explicitly provided, causing risk of centralization of referral bonuses due to an additional 12.5% deposit fee taken for marketing
- There is a 3% dev fee and a 3% marketing fee applied on all deposits and withdrawals, and an additional 12.5% marketing fee only on deposits made without a referral link
- The contract cannot be closed or shut off at any point after deployment
- While there were a couple of medium-risk issues present in the contract, the Coffee Beans team decided to leave them unresolved or be transparent to users
To conclude, this smart contract does what it is designed to. However, since the marketing wallet accumulates a significant amount of referral bonuses, it can potentially drain the contract over time.
