Six Pathways
A Plexo comparison lens for how a named cross-border payment route can fund, convert, control, settle and recover.
By Anton Titov, Founder · Plexo Institute
Plexo uses six labels to compare cross border settlement arrangements. They are not market segments, a legal classification or a forecast of which rail will win.
Plexo uses six labels to compare a named payment route. The labels help structure diligence; they do not predict which architecture will win or prove that it is available in a particular corridor.
Reading Guide
The same questions should be asked of every route: responsibility, assets, liquidity, controls, completion and recovery.
Cross-border payment arrangements can combine different funding, conversion, messaging, settlement and recovery patterns. Plexo groups those patterns into six labels so an operator can compare a real route without treating “stablecoin settlement” as one homogeneous thing. The labels are analytical tools. They are not mutually exclusive, exhaustive or a substitute for a legal or commercial assessment.
| Plexo label | What it asks the reader to inspect |
|---|---|
| Which banks hold the accounts, pass instructions and allocate responsibility? |
| Where are local balances held, and how are cross-entity obligations reconciled? |
| Which group entity funds the route and bears liquidity and control obligations? |
| Who converts, controls the token, pays out and handles exceptions? |
| Which governance, membership, netting and recovery rules bind participants? |
| Which institution issues or settles the asset, and what is live versus experimental? |
The questions behind every label
Identify who owes whom at every leg, which agreement governs the instruction and which jurisdictional perimeter applies. A route label cannot establish a licence, legal enforceability or regulatory permission.
Identify what asset moves on each leg, who owns or controls it, how conversion is arranged and what liquidity is committed. Existing settlement systems and experiments can show design patterns; they do not prove that another network has the same economics or permissions.
Identify the policies, data, screening, completion rule and recovery path that govern the route. Technical confirmation, legal finality and recipient payout may be distinct events.
What the public evidence can and cannot show
BIS work on correspondent banking, multilateral platforms and payment-system interlinking shows that cross-border payment systems use different institutional designs. CLS describes a named, governed settlement system; Project Nexus and Project Agorá describe specific interoperability and tokenized-infrastructure initiatives. These are useful evidence of distinct design patterns. They do not establish that a stablecoin route shares their market reach, risk controls, economics, legal status or production readiness.
Applying the framework to a route
Start with a single proposed corridor. Map its counterparties and customer obligations; list its assets, conversion points and liquidity commitments; specify the relevant data and controls; then define the evidence of settlement and the failure path. A route may deserve more than one label, and its classification can change as the facts change.
The framework deliberately does not recommend a universal maturity path from bilateral settlement to clearing or tokenized institutional infrastructure. A design may be appropriate, unavailable or unsuitable depending on the named route, participants, rulebook and risk appetite.
Counter-Arguments & Limits
Six labels cannot replace corridor-specific facts. They may overlap, a route may not fit neatly into one label, and a current pilot or source-owned metric may not describe a comparable arrangement. The taxonomy is useful only when it makes those limits visible rather than turning them into a forecast or a ranking.

About This Framework
The six-pathway taxonomy is Plexo analysis. The primary sources above establish that different settlement and interoperability designs exist, but not Plexo’s categories, their market shares or an inevitable future order. This framework is not legal, regulatory, financial, investment, tax or compliance advice.
