Our smart contracts do not rely on price feeds from other smart contracts and thus are highly resistant to price manipulation such as flash loan attacks. Tranchess price oracle uses 30-minute TWAP instead of discrete oracle price. This minimizes the possibility of oracle manipulation attack. Tranchess oracle extends the Open Oracle standard by Compound, accepts signed price data from two separate sources (Coinbase and OKEX) and computes time-weighted average price (TWAP) in every 30-minute epoch.
Other security measures includes: Multiple rounds of code audit by reputable teams (Peckshield & Certik), Bug Bounty (Immunefi) and Multi-signature settings.
