Saddle Finance

Saddle is an automated market maker (AMM) enabling trading between pegged value crypto assets. Saddle liquidity pools implement the StableSwap mathematical formula to reduce slippage and keep the market liquid. First introduced by Curve Finance, Stableswap is a hybrid algorithm. The Stableswap hybrid combines both Constant Product and Constant Sum models.

Comparison with Curve

Saddle Finance was accused by Curve Finance of copying its algorithm suggesting the Saddle team had ported its Vyper codebase to Solidity without making any changes[3]. Matt Luongo wrote "good artists borrow great artists steal" as he commited the Saddle contracts to Github[4]

April 2022 Exploit

On the 30th of April 2022, Peckshield twitter account reported an ongoing exploit against the protocol.[5] The Saddle team replied about an hour later by disabling withdrawals and confirming they were investigating the exploit[6].

Saddle Finance TVL fell from $320m to less $100m after withdrawals were enabled.[7] The team later announced that the sUSDv2 metapool was affected by the bug which caused the loss[8].
