Stablecoin-Use Taxonomy

The shared classification language between Kudix and its regulators. Every conversion, alert and report carries one use-case code (U), a provenance layer (P) and any matched risk typologies (R).

Live taxonomy web

How the codes relate: every stablecoin event sits at the centre, crosses the provenance spine (P0→P4), carries one use-case, and may trip risk typologies on the outer ring. The tables below are the same data in full.

Use-case codes (KDX-U)

What the stablecoin was used for

KDX-U1Remittance fundingStablecoin sold to fund a corridor remittance; fiat delivered on domestic rails (e.g. USDT→NGN via NIP).
KDX-U2Fiat on-rampDomestic fiat converted into custodied stablecoin (interface OUT of the domestic system).
KDX-U3Recipient payoutStablecoin→fiat conversion paid to a third-party recipient bank account or wallet.

KDX-U7P2P wallet transferCustodied stablecoin moved between Kudix users; no fiat interface until off-ramp.
KDX-U8Web3 domain purchasePremium .kudix domain bought with stablecoin (KDA revenue).

Provenance layers (P)

Where in the value path an event happened

P0On-chain originSource wallet cluster, chain, hop distance from risk entities; chain-analytics attribution before ingress.
P1Custody ingressAsset enters the MPC custody estate.
P2ConversionDealing desk executes stablecoin↔fiat at the disclosed margin; pre-hedged, no proprietary positions.
P3Domestic settlement interfaceFiat leg touches the domestic financial system via the local rail (NIP, FPS, SEPA, Raast, FAST, SIC, UAEFTS, QATCH, ACH).
P4Cash edgeValue leaves the electronic system as agent cash-out or card spend.

critical
KDX-R2

Mixer / tumbler exposure

Provenance passes through mixing services or privacy pools.

serious
KDX-R3

Cap structuring

Repeated conversions just under sandbox or tier limits (smurfing).

serious
KDX-R4

Mule aggregation

Many senders converging on one recipient account or cash-out agent.

serious
KDX-R5

Rapid on-off ramp

Fiat→stablecoin→fiat round-trip inside 24h with no economic purpose.

warning
KDX-R6

PEP involvement

Party matches a politically-exposed-person list; EDD required.

warning

Darknet exposure

Provenance includes darknet-market-attributed clusters.

Regulator exports use this taxonomy unchanged, so a KDX-U1/R3 alert means the same thing to the FCA, MAS or the CBN: one language across nine regimes, with per-jurisdiction currency figures (₦, £, $, €, د.إ, ₨, S$, Fr, ر.ق) in each national report.
