OasisSwap

Summary

The OasisSwap is an Automated Market Maker (AMM) protocol and a fork of the SushiSwap v2 protocol. The security audit revealed several medium- and low-severity issues related to the updated fee implementation, however, the general security posture of the protocol is robust. The main functional change of the forked project was a new fee structure implementation. Part of the transaction fee is accumulated and withdrawn by the Oasis team, while the remainder is disbursed to liquidity providers, mirroring the distribution method of the original protocol. Secondly, the OasisSwap contracts provide opportunities for select users to receive fee rebates. These fee revisions have been carefully implemented, respecting the key principles of the source protocol. Moreover, the introduced fee structure seamlessly aligns with the established security paradigm of the original protocol, ensuring a consistent and robust foundation for the OasisSwap operation.
