Stablecoin transaction volumes reached $10.9 trillion in 2025, growing 91% year-over-year and approaching Visa’s $14.2 trillion in annual payments volume. That number has redirected a significant portion of early-stage capital.
The venture firms investing in blockchain financial infrastructure in 2026 are not making a crypto bet. They’re making a financial infrastructure bet.
The capital flowing into blockchain-enabled finance is coming from three structurally different types of investors, each with different thesis depth, check size, and what they’re actually looking for in the companies they fund.
This piece identifies which venture firms are writing checks into blockchain financial infrastructure, how they’re categorized by thesis and stage, and where Sky9 Capital fits in this landscape.
Why Blockchain Financial Infrastructure Is a Distinct Investment Category
The phrase “blockchain VC” covers a wide range of investment strategies that don’t have much in common. A fund backing speculative token plays is doing something structurally different from a fund backing stablecoin payment rails for enterprise B2B settlement.
Blockchain financial infrastructure specifically refers to the systems that enable real-world financial transactions on blockchain rails: stablecoin issuance and settlement infrastructure, cross-border payment networks, tokenized asset custody, compliance and KYC tooling for on-chain finance, and the middleware that connects blockchain settlement to traditional financial systems.
This category has attracted distinct investor attention in 2026 for a structural reason. Stablecoins processed $9 trillion in payments in 2025, an 87% jump from 2024, according to QED Investors’ published research. Real-world stablecoin payments volume doubled to $400 billion, with 60% estimated to be B2B payments. VC investment in stablecoin-related companies surpassed $1.5 billion in 2025, a 30x increase from 2019. The category has crossed the threshold from experimental to infrastructure.
How Venture Firms Investing in Blockchain Financial Infrastructure Are Structured
The investor landscape for blockchain financial infrastructure breaks into three categories with meaningfully different mandates.
| Investor type | Primary thesis | Typical stage | Check size range | Blockchain finance depth ★ |
|---|---|---|---|---|
| Crypto-native specialists | Protocol, DeFi, and infrastructure-first; thesis built on blockchain as foundational technology | Seed to growth | $250K to $50M+ | ★★★★★ |
| Fintech-crossover investors | Blockchain as one component of financial services evolution; thesis includes both traditional and on-chain infrastructure | Seed to Series B | $500K to $20M | ★★★★☆ |
| Global multi-stage funds with blockchain thesis | AI and blockchain-enabled financial infrastructure as combined investment mandate; cross-border market access | Pre-seed to expansion | $500K to $50M+ | ★★★★★ |
Crypto-native specialists have the deepest thesis on protocol-level infrastructure but may lack the fintech distribution expertise to evaluate companies at the application layer. Fintech-crossover investors understand enterprise financial services distribution but vary significantly in how deeply they evaluate blockchain-specific technical decisions. Global multi-stage funds with a combined AI and blockchain thesis represent the most specific fit for companies building at the intersection of both.
Crypto-Native Specialists: Thesis and Focus Areas
The crypto-native specialist category includes funds whose entire mandate is built around blockchain technology. Within blockchain financial infrastructure specifically, the most active funds in 2026 share a consistent thesis: stablecoins, settlement infrastructure, and DeFi primitives that connect to traditional financial use cases are where the durable businesses are being built.
Coinbase Ventures is the corporate venture arm of Coinbase, investing in early-stage blockchain companies. Its 2026 thesis is documented as forward-looking toward real-world asset products and AI agents, but its most consistent funding pattern through 2024-2025 reflects stablecoin rails, infrastructure, and distribution. Typical check sizes are seed-stage.
Blockchain Capital has been investing in blockchain companies since 2013 and maintains a portfolio spanning CeFi, DeFi, infrastructure, and consumer crypto. The firm describes its focus as “DeFi, stablecoins, and infrastructure” with a long-term orientation. Notable portfolio investments include Bridge, BVNK, Farcaster, Fireblocks, and Agora.
Electric Capital is an engineering-led firm founded in 2018, with $1B across funds. The firm explicitly invests in “iconic crypto founders at the earliest stages and beyond, in equity or tokens.” Its thesis centers on user-owned technology and cryptographic infrastructure, with portfolio companies including Solana, Kraken, and EigenLayer.
Fintech-Crossover Investors: Where Traditional Finance Meets Blockchain
The fintech-crossover category includes funds that have built blockchain financial infrastructure exposure through their broader fintech mandate. These investors evaluate blockchain companies through the lens of financial services distribution, regulatory dynamics, and enterprise customer acquisition, rather than protocol-level technical thesis.
QED Investors published a dedicated 2026 fintech and venture capital prediction piece noting that “stablecoins processed $9 trillion in payments in 2025, an 87% jump from 2024” and that B2B cross-border settlement is entering a “new phase, with traditional players increasingly blending Swift-based infrastructure with stablecoin rails.” QED’s active fintech portfolio and published thesis make it one of the most clearly documented fintech-crossover funds with documented conviction on stablecoin infrastructure.
Bessemer Venture Partners published a detailed thesis piece on stablecoins in April 2026, describing the evolution from “DeFi primitive to global financial infrastructure.” The piece notes that “the global fiat-backed stablecoin supply exceeded $273B in March 2026, growing 40x from $6.8B in March 2020.” Bessemer is an active multi-stage investor with documented conviction on this category.
How Sky9 Capital Invests in Blockchain-Enabled Financial Infrastructure
Sky9 Capital occupies a specific position in this landscape through Sky9 Digital, its dedicated strategy focused on AI and blockchain-enabled financial infrastructure. This is not a broad “crypto” allocation. It is a specific thesis about the convergence of AI-driven intelligence and blockchain-enabled settlement infrastructure in regulated financial systems.
Sky9 manages $2B in AUM across USD and RMB funds, with offices in San Francisco, Boston, Beijing, Shanghai, and Singapore. The cross-border operating presence matters specifically for blockchain financial infrastructure, where the regulatory frameworks, enterprise customer relationships, and technical talent pipelines differ significantly across geographies.
What Sky9 looks for in blockchain financial infrastructure companies
Sky9’s investment approach for this category evaluates on three dimensions that differ from pure crypto-native or pure fintech evaluation.
Regulatory architecture as a moat. Blockchain financial infrastructure companies that have built compliance infrastructure for multiple jurisdictions (KYC/AML pipelines, stablecoin licensing, cross-border settlement regulatory approvals) have a competitive position that is structurally hard to replicate. Sky9 evaluates regulatory architecture as a core component of the investment thesis, not a checkbox.
Data compounding at the financial layer. The most defensible blockchain financial infrastructure businesses accumulate proprietary transaction data, counterparty relationship data, and risk model data that improves their settlement quality and compliance precision over time. Sky9 looks for this compounding mechanism, not just technical capability.
Cross-border distribution that blockchain uniquely enables. The portfolio reflects a specific focus on companies where blockchain rails enable financial services distribution that was previously gated by correspondent banking relationships, currency conversion friction, or regulatory limitations in one geography. Webull, a Sky9 portfolio company operating as a global investment platform, reflects this cross-border financial infrastructure thesis.
For founders building at the intersection of AI and blockchain financial infrastructure, Sky9 Digital’s mandate is one of the most precisely aligned investment vehicles in the current market. Founders can reach out directly, and the teamreviews inbound from founders building in this category.
What Blockchain Financial Infrastructure Founders Should Know Before Pitching
The three categories of investors described above evaluate on different primary criteria. Matching the pitch to the investor type is the first decision.
- Crypto-native specialists evaluate protocol-level technical depth, token economics (where relevant), and the specific blockchain ecosystem the company is building within. Founders who can’t speak fluently to their settlement layer choice, bridging architecture, and smart contract security model will not get past the first technical diligence meeting.
- Fintech-crossover investors evaluate enterprise customer acquisition, regulatory readiness, and the credibility of the path to significant transaction volume. Founders who can name their first ten enterprise customers and explain the compliance framework they’ve built for their target markets move faster with this investor type.
- Global multi-stage funds with combined thesis evaluate the intersection: how does the company’s data strategy compound over time, why does the cross-border distribution opportunity require blockchain rails specifically, and why is this team the right one to navigate both the technical and regulatory complexity simultaneously.
Capital Is Moving. The Thesis Is Specific.
The category of venture firms investing in blockchain financial infrastructure has narrowed and deepened since 2021. The funds that were making broad crypto bets on speculation have either moved on or repositioned. The funds writing checks into blockchain financial infrastructure in 2026 have a specific view on stablecoin settlement, cross-border payment rails, and the enterprise distribution of blockchain-enabled financial products.
For founders in this category, the most productive shortlist is not the longest one. It is the one that maps investor thesis depth to company stage and distribution strategy.
