Hi @libotony,

This marks the final milestone for the Vearn protocol. It turned out to be a much bigger effort than I originally expected 😅. In case you do the review, my I ask you to put special enphasis on the three key smart contracts: Trader, Roles, and VexWrapper.

Thanks a lot for your support 🙏. Let me know if you have any questions.

Cheers
