Abstract: Embodiments described herein relate to computer systems and methods for derivative or perpetual transactions. The systems and methods involve a plurality of user devices having an interface for the system, the user devices associated with user accounts, each user account having one or more perpetual positions. The systems and methods involve a processing system that includes one or more processors and one or more memories coupled with the one or more processors, the one or more memories storing instructions for a risk engine capable of managing perpetual futures for the trading accounts, each of the trading accounts having its own perpetual positions. The processing system receives input from the interface and generates output for transmission to and display at the interface.

Abstract: Embodiments relate to systems and methods for on-demand margin borrowing and lending with automated de-leveraging. The method for on-demand margin borrowing and lending with automated de-leveraging executing instructions stored on memory by a hardware processor, can involve: enabling margin on a subaccount for cross-collateralization of assets; setting leverage threshold values for the subaccount; processing a loan request to buy or sell an asset from a borrower interface; processing a loan offer to generate returns from idle assets from a lender interface; determining rate for assets; executing a margin transaction between the borrower interface and a lender interface, the margin transaction being smart contract code for a blockchain infrastructure; and computing different types of margin data, and generating output for transmission, storage, or display at an interface.
