Abstract: The Secret Key-Based Counterparty Matching Engine Apparatuses, Methods and Systems (“SKCME”) transforms client key message, order placement input inputs via SKCME components into order placement output outputs. A matched key is determined and used to generate a set of cross times and a set of cross venues for a security identifier. Orders associated with the security identifier are obtained from counterparties and are assigned a scheduled cross time from the generated set of cross times and a scheduled cross venue from the generated set of cross venues. The orders are sent for execution at the scheduled cross venue at the scheduled cross time.

Abstract: The Decentralized Exchange with Price Oracle Apparatuses, Processes and Systems (“DEPO”) transforms decentralized exchange liquidity provision request, decentralized exchange crypto asset swap request, decentralized exchange liquidity redemption request datastructure/inputs via DEPO components into decentralized exchange liquidity provision response, decentralized exchange crypto asset swap response, decentralized exchange liquidity redemption response outputs. A decentralized exchange liquidity provision transaction is obtained via a bidirectional decentralized exchange smart contract deployed on a blockchain. A crypto assets exchange quotient for exchanging a first crypto asset type and a second crypto asset type is determined. A quantity of fungible tokens specific to a crypto assets liquidity tranche datastructure to generate is calculated. The calculated quantity of fungible tokens specific to the crypto assets liquidity tranche datastructure is transferred to a provision blockchain address controlled by a sender of the decentralized exchange liquidity provision transaction.

Abstract: The Decentralized Exchange with Price Oracle Apparatuses, Processes and Systems (“DEPO”) transforms decentralized exchange liquidity provision request, decentralized exchange crypto asset swap request, decentralized exchange liquidity redemption request datastructure/inputs via DEPO components into decentralized exchange liquidity provision response, decentralized exchange crypto asset swap response, decentralized exchange liquidity redemption response outputs. A decentralized exchange liquidity provision transaction is obtained via a unidirectional decentralized exchange smart contract deployed on a blockchain. A crypto assets exchange quotient for exchanging a source crypto asset type and a target crypto asset type is determined. An imbalance rule check for a crypto assets liquidity tranche datastructure is executed. A non-fungible token specific to the crypto assets liquidity tranche datastructure is minted. The non-fungible token is associated with a provision blockchain address controlled by a sender of the decentralized exchange liquidity provision transaction.
