Transaction System and Method

Abstract

The invention relates to systems and methods for executing a digital-asset transaction using a dual-tier messaging architecture. A central messaging server provides tamper detection and message-integrity verification while routing bilateral messages between transacting devices. A permissioned-blockchain channel manages a smart-contract escrow that holds digital assets in cold storage. A fiat-rail channel integrates a real-time payment protocol to obtain bank or rail confirmation that fiat funds are credited to a seller account. Upon receipt of settlement evidence and a validated session state, the escrow releases the digital asset from a seller cold-storage wallet to a buyer cold-storage wallet. Embodiments may capture a seller opt-in via a banking application, generate a dual-ledger audit trail across permissioned and public blockchains, and emit transaction identifiers for cross-system reconciliation. The approach improves compliance, reduces counterparty risk, and provides verifiable audit artifacts for regulated settlement of digital-asset transfers.
