Cyclops, a Miami-based fintech startup building stablecoin infrastructure for payments companies, closed a $20 million Series A led by Nava Ventures on July 15, according to a PRNewswire announcement and Fortune's exclusive reporting. The round included Castle Island Ventures, Coinbase Ventures, Circle, Lasagna Ventures and Global PayTech Ventures, and Nava's Kevin Chenault is joining Cyclops' board.
The Series A follows an $8 million seed round that closed in March 2026, backed by Castle Island Ventures, F-Prime and Shift4 Payments -- meaning Cyclops has raised $28 million total in roughly four months, a fundraising cadence that reflects how fast investor interest in stablecoin infrastructure has moved through 2026.
“Cyclops sells that as a bundled platform, with Shift4 Payments and Mastercard already listed as clients.”
Cyclops' pitch is straightforward: payments companies want faster settlement and cross-border capability using stablecoins, but don't want to build the compliance, custody and rails tooling themselves. Cyclops sells that as a bundled platform, with Shift4 Payments and Mastercard already listed as clients. Founders Alex Wilson, Pat Duffy and David Johnson describe it as the only stablecoin infrastructure company built exclusively for the payments industry, rather than a general-purpose crypto rails provider serving multiple verticals.
The investor composition is worth noting: Circle, a stablecoin issuer, and Coinbase Ventures sit in the same round as Global PayTech Ventures, run by former Mastercard president Javier Perez, a founding investor in Adyen. That mix of crypto-native and traditional-payments-incumbent capital in one Series A suggests both camps see stablecoin settlement rails as inevitable infrastructure rather than a speculative bet.
The bear case: 'infrastructure for a category everyone agrees is coming' is also the pitch behind a long list of stablecoin infrastructure startups now competing for the same payments-company customers, and a four-month gap between an $8 million seed and a $20 million Series A leaves little time to prove out unit economics before the next round. What to watch next: whether Cyclops discloses transaction volume or revenue figures, and whether it can hold onto exclusivity with Shift4 and Mastercard as larger, better-capitalized rails players enter the category.
