Security

DeFI in general is still considered a high risk activity

HappyHippo's team has studied extensively past Ethereum and BSC attacks that have occurred during the past year. Overall 95% of BSC exploits was due to flashloan attacks, Hippo is not vulnerable to these type of attacks as it doesn't use on-chain price data in it's vault logic.

Hippo has also tested about three dozen smart contract security vulnerabilities and economic exploits, including but not limited to

  1. Flash Loan attacks

  2. Reentrancy

  3. Unchecked External cal

  4. Arithmetic Precision

  5. Tx.origin

  6. Overflow/underflow

  7. Type inference

  8. Improper Transfer

  9. In-Loop Transfers

  10. Time dependent logic

  11. ERC20 safeTransfers
