Hello Developers of Laborx. My name is Axis and I'm the owner of an upcoming auto-staking token service on the Avalanche Network called HighPoint. Our goal is to create a fork of Titano.finance but have select things changed to improve security, become more sustainable than other projects, and give our investors a stable and safe stream of passive income. What I need from you is the ability to understand, fork, edit, and create code. More information will be provided if you reach out, I hope to be working with you soon.
Thanks,
Axis.
