Acknowledgement

• This project was built during the Solana Sandstorm hackathon and is strongly inspired by Clockwork and Dcaf Drip projects.

• Maius Invest is in active development and the code is unaudited. Please use at your own risk.

Architecture Overview

Explain

• User sets the necessary parameters for the DCA (deposit_amount, schedule, pause_event,...) and deposits token into the investment vault.

• Each user will have their own investment vault, and each investment vault will have an investment thread managed by the Clockwork Thread program.

• The investment thread contains a swap instruction to place orders on the Openbook Dex according to an established schedule.

• A dedicated backend integrated with the Helius webhook is used to pause the investment thread if a pause_event occurs on the Solana network.

• At the same time, the Openbook Crank program is run to ensure order matching for the investment vault.
