Shiba Link Token - Smart Contract Audit Report
SLINK ($SLINK) is a new community-driven DeFi token on the Ethereum Blockchain Mainnet that pays out static token rewards to holders and sends ETH to the team.
Notes on the Contract:
Audit Findings Summary
- The total supply of the token is initially set to one trillion $SLINK [1,000,000,000,000].
- No minting or burn functions are present; however, holders can send tokens to the 0x...Dead address if desired. If the owner does not exclude the dead address after deploying, it will participate in the reward distribution (as a regular holder) and increase proportionally to the rewards it receives. This is often used as a deflationary mechanism.
- As of the date of this report, 21.57% of the token's supply is within the Dead address.
- 11.39% of the total supply is in Uniswap liquidity.
- 99% of the liquidity has been in a team.finance token locker and will unlock on August 8th, 2022.
- The top ten holders own ~40% of the total $SLINK supply across their wallets.
- There is a 4% 'tax fee' and 8% 'team fee' on all transactions for any "non-excluded" address that participates in a transfer. The owner has the ability to modify these fees to any percentage at any time.
- Users who hold tokens will automatically benefit from the frictionless fee redistribution at the time of each transaction as the tokens collected through taxes are removed from the circulating supply.
- The team fee charged on transactions is stored in the contract and, once a threshold value is met, used to buy Eth from Uniswap.
- The received ETH is then transferred in a 50%-50% split between the Marketing Wallet and the Team Wallet (which happens to be the same address).
- The owner of the contract can exclude and include accounts from transfer fees and reward distribution.
- The owner has the ability to set and update a maximum transaction percent at any time, which will impose a limit to the number of tokens that can be transferred during any given transaction.
- Ownership has been renounced.
- The contract utilizes SafeMath libraries along with following the ERC20 standard.
- No external threats were identified during our analysis of the token contract.
- Please ensure trust in the team prior to investing as they have control of the ETH collected from the 8% fee.
