Cross-Rail Settlement Execution
Route settlement intents across fiat, stablecoin, and crypto rails. The router selects the optimal execution path, matches liquidity, and delivers cryptographic finality - all within a single consensus round.
Five routing primitives in one execution layer
Each primitive handles a distinct piece of the settlement pipeline. Together, they form a unified execution surface across every supported rail.
Multi-Rail Routing
Route settlement intents across fiat (wire, ACH, SEPA), stablecoin (USDC, USDT), and crypto (BTC, ETH via bridges) rails. The router evaluates cost, speed, and availability to select the best path.
Stablecoin-First Execution
Default to stablecoin settlement for speed and deterministic pricing. Fiat and crypto rails activate when stablecoin liquidity is unavailable or the sender specifies a preferred rail.
ISO 20022 Gateway Integration
Ingest and emit ISO 20022 payment messages. Map structured fields (debtor, creditor, amount, purpose code) to on-chain settlement intents for seamless bank-to-chain interop.
AMM v5 Liquidity Matching
Tap the AMM v5 dual-lane liquidity pool for on-chain conversion when cross-asset settlement is needed. Batch auctions ensure fair pricing with MEV protection built in.
Smart Order Routing
Split large settlement intents across multiple rails and liquidity sources when a single path cannot fill the full amount. Minimize slippage, reduce counterparty concentration, and optimize total cost.
How it works
Four steps from intent to finality. Each step produces a verifiable proof anchored to the JIL ledger.
Intent Received
A settlement intent arrives via API, ISO 20022 gateway, or on-chain submission. The router parses amount, currency, destination, and policy constraints.
Rail Selection
The router evaluates available rails based on cost, speed, liquidity depth, compliance zone, and sender preferences. A ranked execution plan is produced.
Liquidity Match
The selected rail is matched against available liquidity. For cross-asset routes, the AMM v5 pool provides conversion at batch-auction pricing.
Execution + Finality
The settlement executes atomically. A finality receipt with cryptographic proof is anchored to the ledger within the same consensus round.
Supported rails
The router connects traditional payment networks, stablecoin liquidity, and cross-chain bridges into a single execution surface.
Fiat Rails
- Wire transfer (domestic and international)
- ACH (US Automated Clearing House)
- SEPA (Single Euro Payments Area)
Stablecoin Rails
- USDC (Circle)
- USDT (Tether)
- Native JIL stablecoin pools
Crypto Rails
- BTC via jBTC bridge (14-of-20 validator custody)
- ETH via jETH bridge (14-of-20 validator custody)
- JIL native L1 settlement
Compliance Boundary
The router selects execution paths. Regulated partners handle the actual fund movement. Fiat rails are operated by licensed payment service providers in each jurisdiction. The JIL protocol provides the intent layer, consensus verification, and finality proofs - it does not hold, transmit, or custody fiat currency.
