That Quantstamp audit states that Saddle Finance’s accomplishing of StableSwap was ported from a Curve Finance codebase “which was acclimated as a reference.” Quantstamp added that capacity above that were unclear: “due to poor documentation, we were not able to actuate how the developers accept acquired some of the implemented formulas from the StableSwap whitepaper.”
The analysis additionally suggests Saddle is accessible to an attack vector aboriginal apparent in Curve Finance. “Since the Saddle Finance affairs are a Solidity accomplishing of the Curve contracts, they are additionally accessible to the aforementioned attack,” the address says.
