DTCC— $XRP & $XLM This image is FIG. 17 from DTCC’s patent US20250078162A1 (“Systems, Methods, and Storage Media for Managing Digital Liquidity Tokens in a Distributed Ledger Platform”). It is a schematic illustration of the transaction chain building process for cross-ledger transfers of tokenized assets. What the Diagram Shows (Overall Flow) The figure demonstrates how the system handles a cross-chain transfer of a tokenized asset (called “ABC token”) between two different blockchains: • From User A on the Stellar DLT System (associated with XLM) • To User B on the Ripple DLT System (associated with XRP) It is not a simple direct arrow from XRP to XLM. Instead, it shows a sophisticated, automated middleware process that finds the best route, builds a chain of sub-transactions, and ensures everything executes safely with fees, compliance, and liquidity in mind. The diagram is divided into three main parts: 1. Bottom-left: Step 1 – Analyze possible payment paths • User A (with a wallet icon) wants to send ABC token to User B. • The system builds a Bridge Graph (a network diagram with nodes and connections representing different ledgers and bridges). • It pulls existing paths between systems (Stellar Bridgehole, Ripple Bridgehole, and others shown as circles). • This creates possible routes across heterogeneous networks using bridges. 2. Bottom-right: Step 3 – Validate chains • A decision-tree flowchart checks each potential chain: • “Does each link contain all reference variables?” (YES/NO) • “Does each link have enough balance to make transfer?” (YES/NO) • If valid → “Add chain to options list” • If not → skip or stop transaction chain. • This ensures the transfer is feasible before execution. 3. Top/main section: Step 2 – Build chains (the core visual) • Multiple Transaction Chains (e.g., TransactionChain 1, 2, etc.) are constructed. • Each chain consists of several TransactionLink boxes (1 through 5). • Inside the links you see terms like: • “Bridgehole Stellar Base Trade Wallet” • “Bridgehole Ripple Issue Trade Wallet” • “Bridgehole Fee Wallet” • Transfers between wallets (e.g., User A Stellar Token Transfer → Bridge → User B Ripple Token Transfer) • Arrows show the flow of the ABC token (or equivalent) across bridges. • A “MERGE” point combines viable chains into a final optimized transaction chain. • On the right side, you see the expanded final chain with sub-steps like issuing, trading, fee collection, and delivery to User B’s wallet.
