The Problem
Cross-border payments between Japan and Korea today involve:- 1-3 business days to settle through correspondent banking chains
- Herstatt risk — one party delivers but the other hasn’t yet
- Multiple intermediaries — 2-4 correspondent banks, each adding fees and latency
- Opaque FX rates — bank’s internal pricing, no competitive bidding
- Fragmented audit trails — SWIFT messages at each hop, no single proof of settlement
The Solution
| Property | What It Means |
|---|---|
| Atomic DvP | Both currency legs settle in a single transaction. All four settlement legs succeed, or all roll back. No counterparty risk, ever. |
| Competitive RFQ | Market makers compete on price via anonymized requests. Best execution is documented and auditable. |
| Privacy by design | Each participant sees only the data they’re authorized to see. Market makers never see sender/receiver identity. |
| Built-in compliance | Every order is a complete audit record — KYC references, jurisdiction codes, timestamps, and a single settlement proof hash. |
Key Numbers
| Metric | Value |
|---|---|
| End-to-end settlement | ~15 seconds |
| Settlement legs per transaction | 4 (atomic) |
| Required signatories per settlement | 4 (operator + sender custodian + market maker + receiver custodian) |
| Counterparty risk | Zero (atomic DvP) |
| Settlement proof | 1 transaction hash covering all legs |

Architecture
Each participant runs their own isolated infrastructure — backend, database, and settlement node. No shared systems, no shared data. Cross-party coordination flows exclusively through the settlement network.Current Status
Musubi is deployed on the Canton Network testnet for POC validation with institutional participants across Japan and Korea.
