Slavik Baranov, STON.fi CEO

STON.fi Dev, the core development team behind STON.fi, the leading DEX and foundational DeFi protocol suite on TON blockchain, has successfully raised $9.5 million in a Series A funding round led by premier global investment funds — Ribbit Capital and CoinFund. This funding marks a major milestone in STON.fi’s mission to build cross-chain solutions and robust on-chain liquidity infrastructure for users and developers, leveraging deep integrations with Telegram-native wallets and the broader TON ecosystem. This investment underscores the growing recognition of decentralized finance’s potential on TON and reflects deep confidence in STON.fi’s mission and performance.

Since launching in November 2022, STON.fi has emerged as the backbone of DeFi on TON blockchain, facilitating over $6 billion in trading volume through more than 27 million transactions. With unmatched token coverage, deep liquidity, and market dominance in total value locked (TVL) and trading volume, STON.fi has become the protocol of choice for ~ 80% of all TON traders. It currently ranks #1 on TON by unique active wallets, and its infrastructure empowers users, developers, and liquidity providers alike.

This new funding round will fuel STON.fi’s continued innovation and expansion. The capital will be used to develop concentrated liquidity pools for enhanced capital efficiency, launch native limit order functionality, introduce a community governance layer, and implement other major core protocol optimizations. STON.fi is also investing heavily in developing cross-chain capabilities via its liquidity aggregation protocol Omniston, which will enable seamless, bridge-free swaps across blockchains — a critical step toward a unified DeFi experience.

"Our Series A round is more than just funding — it's a strong vote of confidence from some of the most visionary investors in the industry," said Slavik Baranov, CEO of STON.fi Dev. “It affirms STON.fi’s role as the foundational DeFi layer on TON and validates our relentless focus on building products that matter. This investment will accelerate our ability to scale, innovate, and deliver a truly borderless decentralized financial infrastructure.”

"STON.fi has quickly become the gravitational center of DeFi activity on TON, and we believe it’s just getting started,” said Alex Felix, CIO of CoinFund. “We always strive to identify protocols with the potential to redefine user experience and infrastructure at scale, and STON.fi is doing exactly that. From pioneering deep on-chain liquidity to enabling seamless, bridge-free swaps across chains, their roadmap reflects a bold vision for what next-gen DeFi can be. We’re proud to support their journey as they set new infrastructure standards for decentralized finance."

As STON.fi continues to expand its role within the TON DeFi ecosystem, this Series A raise marks a critical milestone — enabling the protocol to accelerate adoption and shape the future of decentralized finance across chains.
