Abstract

See full text

The Address Verification, Seed Splitting and Firmware Extension for Secure Cryptocurrency Key Backup, Restore, and Transaction Signing Platform Apparatuses, Methods and Systems (“SFTSP”) transforms contract deployment request, transaction signing request, key backup request, key recovery request inputs via SFTSP components into contract deployment response, transaction signing response, key backup response, key recovery response outputs. A contract deployment request message datastructure is obtained. Owner key identification parameters are determined. An owner public key is determined using the owner key identification parameters. An owner address is generated using the owner public key. A salt value is generated. A contract address for the smart contract is calculated as a function of the deployment factory address, the salt value, the contract code, and the owner address. An owner private key is determined using the owner key identification parameters and used to sign the contract address. A contract deployment data datastructure is provided.
