The inaugural xStocks Hackathon on the French Riviera compressed the future of tokenized equities into 48 hours, as 60 builders shipped prime brokerage, yield and strategy primitives on top of Kraken’s xStocks framework. Hosted alongside EthCC, the builder-focused “Market Open” hacker house awarded first place to xPrime, second to Stretch by Spreads and third to xStream, with discretionary prizes going to Paragon, Aura and Otomato. Their work lands at a moment when tokenized stock markets have reached roughly a $1.2 billion market cap and xStocks alone has logged more than $25 billion in total transaction volume across centralized and on-chain venues. For Kraken and its partners, these projects are not side experiments but early blueprints for how equities, blockchain and digital assets will converge into parallel capital markets that run 24/7.

xStocks itself is pitched as a “next-generation framework for tokenized equities,” enabling the seamless transfer of real-world stocks and ETFs between centralized and decentralized environments and giving global investors round-the-clock exposure to U.S. names. Backed by fully collateralized, 1:1 tokens that mirror underlying securities like Tesla or Nvidia, the platform has rolled out to eligible European Union users and expanded across Solana, Ethereum and other networks. According to a recent report from crypto.news, xStocks now offers more than 60 tokenized U.S. stocks and ETFs, has processed over $25 billion in cumulative transaction volume in under eight months and is being integrated into venues ranging from Kraken’s main exchange to DeFi protocols. Kraken has also launched xChange, an on-chain trading engine that connects more than 70 tokenized equities across Ethereum and Solana, with $3.5 billion in on-chain volume and 80,000 holders already using the system. This backdrop of liquidity, infrastructure and regulatory structuring is what the hackathon winners plugged into as they tried to answer a simple question: if stocks are programmable, what should we build first?

First-place winner xPrime positions itself as a prime brokerage layer for tokenized equities, aimed at sophisticated traders and funds that want margin, leverage and cross-asset strategies built directly on xStocks. “We built xPrime, a prime brokerage for onchain equities,” the team wrote, adding that they were “grateful to win the @xStocks Hackathon by @krakenfx with @0xdivergence @0xscanty,” underscoring the project’s focus on institutional-grade functionality. By design, a prime brokerage on-chain means unified collateral management, rehypothecation rules enforced in smart contracts and cross-margining across tokenized positions that can settle in seconds, not days. In practice, xPrime’s approach plugs into a market where xStocks has already surpassed $25 billion in transaction volume and $3.5 billion in on-chain flow, suggesting there is sufficient liquidity to support more complex financing and lending arrangements around tokenized stocks.

The team behind xPrime framed their late entry and eventual win as evidence of pent-up demand for richer equity rails. “Amazing organization, glad to be part of it. prime time!” wrote @0xdivergence, one of the builders, while another participant described the event as “goated event production” and praised the quality of projects. That tone was echoed by xStocks itself, which responded “xPrimeeee” and congratulated the team on the “greaaaaaaat build,” signaling that prime brokerage-style infrastructure is core to the ecosystem roadmap and not a novelty. In the broader market, large institutions are moving in the same direction: Morgan Stanley has outlined plans to support tokenized stocks on an internal venue by late 2026, while the New York Stock Exchange has floated a 24/7 blockchain-powered trading venue for tokenized securities. As tokenized stock markets grow toward and beyond the current $1.2 billion capitalization, prime brokerage primitives like xPrime could become key plumbing for leverage, securities lending and structured trades around assets that live simultaneously on traditional and blockchain rails.

Second-place winner Stretch by Spreads came out of the inkonchain and xStocks ecosystem, with the ink team noting that the builders “took a different approach – building Stretch, which focuses entirely on a single tokenized stock: $STRC.” Instead of constructing a broad prime brokerage, Stretch honed in on one name and designed structured exposure around it, effectively turning a tokenized stock into a programmable building block for yield, leverage and risk management. That focus aligns with how xStocks is being used more broadly: according to a recent crypto.news story, the platform’s fully backed tokens mirror U.S. equities like Tesla and Amazon while allowing fractional ownership, 24/5 trading and composability with DeFi protocols for yields that go beyond simple price appreciation. In this framing, a ticker like STRC is no longer just an isolated stock but a collateral type that can back loans, power options-like payoff structures or feed into automated strategies across Ethereum and Solana.

The Stretch team’s decision to narrow in on a single ticker underscores how tokenized stocks shift the design space for equity products. Instead of waiting for a bank’s structured products desk to launch a note, developers can ship programmable payoff curves in a hackathon sprint, with terms enforced by smart contracts and positions settling in stablecoins or on-chain cash equivalents. This trend intersects with a broader wave of tokenization across finance: MetaMask has integrated more than 200 tokenized U.S. stocks and ETFs via Ondo, Trust Wallet has brought xStocks exposure to over 200 million users and multiple venues now treat tokenized equities as standard collateral for borrowing and derivatives. As more of that liquidity migrates on-chain, projects like Stretch hint at a future where every major stock has a cluster of open-source strategy contracts around it, offering configurable risk and reward profiles that mirror, and sometimes surpass, what is available in traditional markets. For traders, that could mean using a single interface to dial in targeted exposure to a name like STRC or NVDAx – with the underlying tokenized equity trading around the clock and settling natively on-chain.
