Systems and methods for a secure cross-chain atomic swaps are disclosed herein. A user submits to a swap platform a signed limit order to atomically swap an amount of input token for an output token. The swap may involve a Dutch auction approach, in which the order execution price depends on time of inclusion in a block and decreases over the duration of the Dutch auction. The swap platform provides the order details to whitelisted resolvers to evaluate if / when / how to fill the order. Once a resolver makes that determination, it can utilize smart contracts associated with the swap platform to perform the atomic swap on behalf of the user and itself (e.g., without active involvement of the user). Input tokens deposited on an escrow contract are unlocked at the same time that output tokens deposited on another escrow contract are unlocked.

An adaptive orchestration platform routes quantum-computing jobs to optimal backends in real time. A broker service ingests a quantum job description expressed in a provider-agnostic canonical schema, polls status metrics for multiple candidate processors, and derives composite scores using machine-learned, user-weighted factors. The highest-scoring backend is selected, and the job is automatically translated into its native instruction format. Payment is secured by a blockchain escrow smart contract that releases segmented disbursements upon queue confirmation, execution start and verified completion against service-level parameters. Results are hashed to an immutable ledger and failures trigger automated re-routing or refunds.

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.
