Correspondent Chains
A single payment can hop across multiple correspondent banks, each holding, screening, and forwarding funds independently. Every hop is a point where state is lost and accountability blurs.

Cross-Border Payments
Foundations for clearer global movement of value — built on defined corridors, predictable flow states, and transparency designed in from the first instruction.
In Development
01 / Problem
Where Cross-Border Breaks
Cross-border payments rarely fail loudly. They degrade quietly through chains of intermediaries, each adding delay, cost, and uncertainty. Understanding the mechanism — not just the frustration — is the first step to designing around it.
Unpredictable Landing Times
Because each intermediary applies its own processing windows and checks, arrival time becomes a probability distribution rather than a commitment. The payer cannot see where value currently sits.
Hidden Cost Stacking
Fees and spreads are applied at each stage, often deducted from principal in transit. The sender's quoted cost and the recipient's actual receipt frequently diverge.
02 / Architecture
Corridor Architecture
A corridor is a defined route between endpoints with a fixed set of states and requirements — not an open-ended path through the correspondent network. Corridors are in development; none are represented as live or available.
- Corridor Definition
- A named, versioned route with explicit endpoints, supported directions, and operating parameters.
- Supported Instruction Types
- The specific instruction categories a corridor is designed to accept, declared per corridor.
- Standardized Flow States
- A shared state model so every corridor exposes the same observable lifecycle to integrators.
- Pre-Flight Validation
- Validation performed before funds move, surfacing errors while they are still cheap to correct.
- Data Requirements Per Corridor
- Explicit data fields a corridor requires, so integrators know upfront what must accompany an instruction.
- Predictable Settlement Path
- A defined route to destination settlement, designed to remove reliance on opaque intermediary chains.
03 / Flow
Payment Flow
Each cross-border payment is designed to move through explicit steps. At each step, Railix intends to expose a transparency signal to the payer, so the payment's position is always observable.
- 01
Quote & Validate
The instruction is priced and checked against corridor requirements. Transparency signal: a quote showing expected cost and receipt before initiation.
- 02
Screen
Parties and instruction are evaluated against screening rules. Transparency signal: a screening state indicating cleared, hold, or rejected.
- 03
Fund
The funding source is confirmed as available. Transparency signal: a funding-confirmed event tied to the instruction.
- 04
Route
The payment enters its defined corridor path. Transparency signal: a routing state naming the corridor and current position.
- 05
Settle At Destination
Value is settled to the destination endpoint. Transparency signal: a destination-settlement event with the final reference.
- 06
Confirm & Reconcile
Settlement is confirmed and matched to internal records. Transparency signal: a reconciled state linking the payment to its ledger entries.
Design intent only. Signals and steps describe the model under construction and are not commitments to specific corridors, costs, or timings.
04 / Transparency
Transparency By Design
Transparency is treated as a first-class product property, not a reporting afterthought. The following are design goals for the cross-border experience.
Full Cost Visibility (Design Goal)
The intent is to show total expected cost and recipient receipt before an instruction is initiated, rather than revealing deductions in transit.
Traceable State At Every Hop
Every stage of the defined path is designed to be observable, so a payment is never in an unknown location.
Structured Failure & Return Reasons
Failures and returns are designed to carry structured, machine-readable reasons rather than opaque rejections.
Audit-Ready Records
Each payment is designed to produce a complete, reconstructable record suitable for audit and dispute handling.
Clearer Global Movement Of Value
Corridors are in development and none are live today. Request early access to follow corridor progress and help define transparency requirements.
