When OpenTrade's co-founders left the rarefied world of Circle and Coinbase's USDC consortium, they saw something most observers had missed: a widening gap between the trillions sitting in digital dollars and the vanishingly few ways to earn a return on them.
Three years later, that bet appears to be paying off—perhaps more than the founders expected.
The London-based startup, which builds yield infrastructure for stablecoins, announced a $17 million strategic funding round on May 6, bringing its total capital raised north of $30 million. Mercury Fund and Notion Capital co-led the round, with a16z crypto, AlbionVC, and CMCC Global joining in. Both lead investors had backed OpenTrade's $7 million raise just eleven months earlier, a vote of confidence that suggests momentum rather than mere follow-on obligation.
What's fueling that momentum? Transaction volumes that tell a story of rapid acceleration. OpenTrade processed more than $250 million by the end of 2025, then blew past $300 million by April 2026. The company projects it will cross $1 billion in annual transaction volume before year-end—a forecast that might have seemed ambitious if not for the trajectory already visible in the numbers.
The Infrastructure Play Nobody Asked For (Until They Did)
OpenTrade isn't chasing retail investors directly. Instead, it's built the pipes and plumbing that let fintechs, neobanks, and crypto exchanges offer dollar- and euro-denominated yield products without standing up their own asset management operations. Think of it as the kitchen supplier for platforms that want to serve yield but don't want to become investment managers.
The platform now holds over $200 million in total value locked—a milestone disclosed alongside the funding announcement. Its client roster spans continents and use cases: Argentine fintech Buenbit, which claims 4 million users; Colombian neobank Littio; and crypto exchange WOO X, among others. The geographic spread across Latin America and EMEA reflects deliberate positioning in markets where dollar-denominated yields matter more, where local currencies carry inflation risks that make stable returns in USD or EUR particularly attractive.
CEO Dave Sutter and co-founder Jeff Handler both cut their teeth at Centre, the governance consortium behind USDC, and worked on the Marco Polo enterprise blockchain project. That pedigree shows in the platform's architecture, which forked Circle Research's open-source Perimeter Protocol as its foundation. They're not reinventing stablecoin credit markets so much as productizing them.
Two Lanes, Same Destination
OpenTrade operates what it calls a "dual-layer" approach—industry speak for running both permissioned rails (for custodial platforms that need regulatory cover) and permissionless infrastructure (for protocols and power users comfortable with blockchain-native operations).
Current product offerings range from conservative to decidedly less so. USD money market fund vaults yield roughly 3.85% annually. A flexible-term EURC vault backed by European sovereign bonds sits around 1.73%. Then there's a high-yield corporate bond vault tracking BlackRock's HYCB ETF at approximately 7%, and what the company calls "Rates+ vaults" backed by commercial paper, trade finance, and private credit—with yields stretching from 5% to 14%.
That last category carries obvious risk, even as it draws clients hunting for returns in a world where traditional savings accounts have spent years paying next to nothing.
The permissionless side launched through Sierra Protocol's SIERRA liquid yield token on Avalanche in late 2025, with OpenTrade managing the dynamic reserves. It marked a strategic shift beyond purely white-label infrastructure, testing whether the company could serve both custodial platforms and DeFi protocols without losing focus.
Where the Money Goes
The fresh capital will flow into three areas, according to the company: expanding permissioned infrastructure for custodial clients, growing the permissionless protocol layer, and building out something called Curation+—a vault curation and investment strategy service developed with FCA-regulated partner Five Sigma Finance.
Hiring plans span engineering, asset management, and customer success. Geographic expansion is also on the roadmap, though specifics remain vague.
OpenTrade's pitch leans heavily on compliance infrastructure: bankruptcy-remote special purpose vehicles, regulated asset managers, segregated accounts at financial institutions. It's the scaffolding required to convince traditional financial platforms that they can offer crypto-adjacent yields without stepping into regulatory quicksand.
The company brought on Maxime de Guillebon as COO in 2024—a notable hire given his previous role as CEO of Zodia Custody, a venture backed by Standard Chartered and Northern Trust. That kind of traditional finance credibility matters when your clients include banks and regulated fintechs.
The Bigger Wave They're Riding
OpenTrade's growth trajectory intersects with larger market shifts that have little to do with the company itself. The stablecoin market crossed $300 billion in total supply during 2025. Tokenized Treasury products—digital representations of U.S. government debt—have mushroomed into a multi-billion dollar category, with BlackRock's BUIDL, Franklin Templeton's BENJI, and Ondo's offerings leading the charge.
Meanwhile, fintechs and exchanges face mounting pressure to monetize stablecoin deposits sitting idle on their platforms. Offering yield is an obvious answer, but most lack the infrastructure, licenses, or expertise to do it themselves. Enter platforms like OpenTrade.
The funding round itself wasn't labeled a Series A by most coverage—outlets described it as a strategic raise, with valuation undisclosed. That framing might signal an inside round or suggest the company prefers to avoid the Series A nomenclature given the timing and structure. Either way, the capital provides runway for what comes next.
What Lies Ahead
OpenTrade's roadmap hints at ambitions beyond serving custodial platforms and DeFi protocols. The company talks about treasury management operations and, potentially, partnering with stablecoin issuers themselves. Product plans include managed DeFi vaults and emerging market bond products currently listed as "coming soon"—corporate speak for "we're working on it."
Whether OpenTrade can execute on that vision depends on variables beyond its control: regulatory clarity, continued stablecoin adoption, and whether traditional finance platforms embrace tokenized yields at scale. The $200 million in TVL suggests early traction. The accelerating transaction volumes point to demand that may be real rather than speculative.
But there's a gap—and it's not a small one—between processing hundreds of millions and becoming the default infrastructure layer for stablecoin yields globally. OpenTrade is betting that gap will close as more platforms decide they need yield infrastructure without the headache of building it themselves.
For now, at least, investors seem willing to bet alongside them.
