RockawayX is a blockchain-focused venture capital firm based in Prague, Czech Republic, with a global investment footprint and a long-term focus on value creation in the crypto ecosystem. Founded to back the most promising founders, protocols, and applications in web3, RockawayX has emerged as a key institutional investor supporting infrastructure and application layers of blockchain technology. The firm actively contributes to its portfolio projects beyond capital by offering operational support through its in-house engineering, validator infrastructure, and ecosystem services. RockawayX has offices in Prague, London, and Dubai, and operates with a team of over 45 professionals.
RockawayX invests in early-stage crypto startups and protocols with a particular focus on the Solana blockchain. The firm backs companies globally, prioritizing those building in decentralized finance (DeFi), blockchain infrastructure, and web3 middleware.
While its capital is stage-agnostic, RockawayX leans into seed rounds and selectively deploys capital into income-generating opportunities, such as on-chain credit and liquidity provision. Rather than focusing on Layer 1 blockchains, RockawayX concentrates on supporting application-layer ventures, developer tools, and decentralized services designed to drive mainstream adoption of blockchain.
In May 2025, RockawayX announced the close of its second fund, raising $125 million to double down on its Solana-centric thesis. The fund allocates two-thirds of its capital to early-stage equity deals - primarily seed rounds - while the remainder is reserved for income-generating liquid strategies, including an existing $100 million on-chain credit pool offering annualized returns of approximately 12%.
With this new vehicle, RockawayX aims to be the first institutional user for its founders, supporting startups not just with funding but also with services such as validator operations, hardware infrastructure, liquidity provisioning, and technical auditing.
The firm’s investment strategy combines equity stakes in promising web3 ventures with protocol-level support, ensuring deep alignment with founders from inception through scale.
This latest raise follows strong performance from RockawayX’s first fund, which posted a 2.1x DPI and 5.4x MOIC, signaling robust early returns in a volatile market.
Leadership
The firm is led by Managing Partner Viktor Fischer and supported by a team with deep technical and crypto-native expertise. RockawayX distinguishes itself by running its own proprietary infrastructure - such as validators and hardware services - designed to strengthen the networks it backs.
The firm takes an active role in helping projects launch and scale, making daily contributions to protocol codebases, providing engineering support, and acting as a design partner for product-market fit.
Notable Investments
RockawayX was one of the earliest institutional backers of Solana in 2018 and has since built a portfolio of more than 15 companies in the Solana ecosystem. Other notable investments include Helio, a Solana-based payments platform, and Blocktorch, an observability platform for decentralized applications.
The firm also supports its projects through on-chain liquidity and operational infrastructure, uniquely positioning it as both investor and ecosystem contributor.
