STON.fi Dev raises $9.5M in Series A funding

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 the investment funds Ribbit Capital and CoinFund. STON.fi is a portfolio project of The Open Platform (TOP).

STON.fi is the leading DEX on TON Blockchain and also offers a suite of swap-enabling protocols. The project is recognized for its high token variety and deep liquidity, as well as its dominance in total value locked (TVL) and trading volume.

With over $6 billion in total trading volume and more than 27 million operations, it has become the backbone of TON’s DeFi ecosystem. STON.fi integrates directly with TON wallets and supports all TON-based tokens, while also enabling token swaps, liquidity provision, and other opportunities.

STON.fi is also investing heavily in developing cross-chain capabilities via its liquidity aggregation protocol Omniston, which enables seamless, bridge-free swaps across blockchains — further integrating TON Blockchain with the global crypto market.

"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.”

This new funding round will fuel STON.fi’s continued expansion. The capital will support the development of cross-chain operations via liquidity aggregator Omniston, the creation of concentrated liquidity pools for enhanced capital efficiency, the launch of native limit order functionality, the introduction of a community governance layer, and other major core protocol optimizations.

"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.
