    Core Feature

    Atomic Delivery-versus-Payment

    True atomic DVP ensures that asset transfer and payment occur simultaneously or not at all. No counterparty risk. No settlement failures. No manual reconciliation.

    • Simultaneous Exchange — Asset and payment in single transaction
    • No Counterparty Risk — Escrow-free settlement
    • Automatic Rollback — Failed conditions revert atomically
    • Multi-party Support — 2+ party settlement coordination

    Infrastructure

    Four-Chain Architecture

    Settlement flows across four blockchain networks, each serving a specific function in the transaction lifecycle.

    • Hyperledger Fabric — Permissioned custody and tokenization
    • XRP Ledger — NFT representation and XRP settlement
    • Ethereum — DeFi integration and ERC-721 wrapping
    • Canton Network — Institutional final settlement

    Privacy

    Sub-Transaction Privacy

    Canton Network's DAML runtime provides sub-transaction privacy — parties only see the portions of a transaction they're authorized to view. No global visibility.

    • Need-to-Know Basis — Parties see only their portion
    • No Global Ledger — No public transaction history
    • Regulatory Compliant — Auditors can be granted observer rights
    • Confidential Amounts — Values hidden from non-parties
