initial theory
maritime shipping moves $100B+ annually across dozens of currencies with 42-day average settlement. stablecoins should compress this to minutes.
hypothesis
a stablecoin-native payment layer could capture float yield, reduce FX costs, and free working capital for mid-size ship management companies.

primary research
research method: 4 insider interviews across ship management, crew payroll operations, maritime fintech, and port agency. each interview tested specific assumptions from desk research against operational reality.
| assumption | desk research said | insiders said | impact |
|---|
| crew payments are slow and painful | 42-day average, multi-currency nightmare | partially true. payroll is painful but ship managers have workarounds; the real pain is compliance, not speed | weakened |
| 42-day settlement is the norm | industry average from trade press | misleading. 42 days is for charter hire disputes, not routine crew pay; crew payroll settles in 7-14 days via existing fintech | debunked |
| FX savings would drive adoption | 3-5% FX spread on emerging-market currencies | real but insufficient. ship managers negotiate bulk FX rates; savings would be 0.5-1% at best, not enough to change behavior | weakened |
| ship managers would welcome stablecoins | crypto-curious industry seeking modernization | false. extreme regulatory caution; compliance officers veto anything with "crypto" in the name; need bank-grade rails or nothing | debunked |
maritime payroll flow (current state)
ship master
→
shore verification
→
corporate treasury
→
SWIFT / fintech
- ship master submits crew payroll request with allotments in 8-12 currencies
- shore verification cross-checks against employment contracts, ITF agreements, and flag-state regulations
- corporate treasury batches payments weekly, executes FX, and routes through SWIFT or a maritime fintech like ShipMoney
why deprioritized
competitive timing
Marcura raised $15M and began building stablecoin settlement in-house. JPM Kinexys went live for large maritime counterparties. the window for a startup to wedge in is narrowing to months, not years.
top of market captured
the largest ship managers (200+ vessels) already have treasury operations sophisticated enough to capture most of the value proposition internally. the mid-market is where opportunity remains, but it's harder to reach and lower margin.
regulatory wall
maritime payments cross 30+ jurisdictions per voyage. compliance officers at ship management companies universally vetoed "crypto-adjacent" solutions. rebranding as "digital dollar settlement" helps but doesn't eliminate the objection.
primary research gap
desk research painted a much rosier picture than reality. the 42-day settlement figure was misleading, FX savings were overstated, and crypto receptiveness was fabricated by the trade press. without primary research, this would have been a costly mistake.
infrastructure gap
building stablecoin rails that satisfy maritime compliance requires banking partnerships, money transmitter licenses in 10+ jurisdictions, and integration with legacy maritime ERP systems. estimated 18-24 months and $2-4M before first revenue.
important framing: deprioritized does not mean the thesis is wrong. stablecoins will eventually dominate maritime cross-border payments. the question is whether a startup can capture that transition, or whether incumbents (Marcura, banks) will absorb it. the research says incumbents win this one.

| player | approach | strength | weakness |
|---|
| Marcura | maritime-native payments platform adding stablecoin settlement | 700+ ship manager clients, deep domain expertise, $15M funding | slow product cycles, legacy tech stack |
| JPM Kinexys | bank-grade blockchain settlement for large maritime counterparties | regulatory compliance built-in, JPMorgan brand trust, live product | enterprise-only, ignores mid-market, no crew payroll focus |
| my startup | stablecoin-native payroll layer for mid-size ship managers | speed, focus, stablecoin-native architecture, niche targeting | no distribution, no maritime credibility, no licenses, no funding |
verdict: deprioritized, not abandoned
the thesis survived initial evaluation but the timing window is too narrow. the 15,000+ words of research are worth more as demonstrated thinking than as a company.
