If you use LP-Swap to swap 100 BUSD for 5 CAKE with 1% slippage:
First, LP-Swap smart contract calls a private smart contract to perform the swap. This smart contract is private because it contains the secret sauce.
Then, LP-Swap smart contract verifies the private smart contract returned you at least 99% of your 5 CAKE, i.e. 4.95 CAKE. If it did, the transaction is accepted. If it didn't, the transaction is reverted.
2. No user fund held
The vast majority of DeFi exploits consists of stealing users funds held in smart contracts. However LP-Swap smart contract holds no user fund, thereby protecting LP-Swap users from most DeFi exploits.
3. Heavy testing
Every time we modify LP-Swap smart contract, we extensively test it via a battery of unit and manual tests.
We got audit offers from multiple audit firms. Audit is in progress.
