Woof Finance - Smart Contract Audit Report
Summary
Woof Finance is a token where fees charged on transfers are shared among token holders instantly.
We reviewed Woof's token contract at 0x6c2e5dfa3392debe43d8b2cb49b085cd1fdb3fcc on the Ethereum mainnet.
Notes on the contract:
- Woof Finance is a fork of Reflect Finance (RFI). The key change implemented is the increased total supply, doubling of the transaction fee for redistribution, and addition of a developer's fee.
- The total supply of the token is 1 trillion.
- 24% of the supply is in a locking contract, but the team can withdraw these tokens at any time.
- An additional 48% of the supply is in the same locking contract, which willy fully unlock in 11 days.
- An additional 7% of the supply will be released from another contract to the team in 2 days.
- 1.8% of the token's supply is in the Uniswap liquidity pool. 40% of liquidity is held by the team, the remaining 60% unlocks in 2 years.
- The next largest holder has 1.6%.
- No mint functions exist. After deployment, the total supply is 1 million tokens which are all sent to the deployer's address. No burn function exists.
- There is a 2% fee on token transfers which is redistributed to existing token holders instantly and automatically at the time of each transaction.
- There is an additional 1% fee on transactions which will be sent to the team.
- The owner can exclude any address from the fee mechanism.
- Proper utilization of SafeMath to prevent overflows.
Audit Findings Summary
- No security issues were identified.
- The team controls a very large majority of the supply and can empty the liquidity pool at any time. Ensure trust in the project team.
