July 30, 2025 – STON.fi, the leading decentralized finance (DeFi) protocol built on The Open Network (TON) blockchain, today announced the successful close of its $9.5 million Series A funding round. The significant investment was co-led by prominent venture capital firms Ribbit Capital and CoinFund, underscoring strong investor confidence in STON.fi's vision and its pivotal role in the rapidly expanding TON ecosystem.
This substantial capital infusion arrives as STON.fi demonstrates remarkable growth and market dominance within the TON network. The platform has processed over $6 billion in trading volume and executed more than 27 million transactions, capturing over 80% of the TON user share. The Series A funding will be strategically deployed to accelerate product development, expand its ecosystem, and further enhance its offerings to meet the growing demand for decentralized financial services on TON.
"This Series A funding from Ribbit Capital and CoinFund is a powerful validation of our progress and our ambitious vision for DeFi on TON," stated STON.fi Leadership. "We've built a robust and efficient automated market maker (AMM) that is already seeing incredible adoption, becoming the go-to platform for users within the TON ecosystem. With this new capital, we are poised to deliver even more innovative features, expand our cross-chain capabilities, and empower the TON community through decentralized governance, truly cementing our role as the core DeFi layer."
STON.fi operates as a decentralized AMM protocol, enabling users to instantly swap Toncoin for any other coin or token at optimal rates directly within the TON blockchain. Key benefits of the platform include:
- Virtually Zero Trading Fees: Leveraging the TON blockchain's low transaction costs and high speed.
- Low to Zero Slippage: Utilizing sophisticated algorithms and liquidity pools for efficient price discovery.
- Fully Decentralized and Secure: STON.fi does not hold user funds or request personal information, ensuring complete user control. Its v2 smart contracts have undergone a comprehensive security audit by Trail of Bits, a leader in blockchain cybersecurity.
- Easy Interface and Direct TON Wallet Integration: Providing a seamless user experience.
A cornerstone of STON.fi's innovation is Omniston, a decentralized liquidity aggregation protocol. Omniston is designed to supercharge TON DeFi applications by seamlessly connecting them to multiple liquidity sources with a single integration, unlocking deep liquidity and optimal swap rates for TON-based projects.
Looking ahead, STON.fi has outlined an ambitious roadmap to further enhance its platform and expand its reach:
- Advanced Trading Features: Introduction of limit orders and margin trading.
- Enhanced Cross-Chain Capabilities: Development of a cross-chain trustful protocol and an SDK for cross-chain operations, including direct swaps between TON and TRON USDT without bridges or wrapped tokens. Future integrations will extend to Polygon and other EVM chains, as well as additional blockchain networks.
- User Experience Improvements: Implementation of gasless swaps and a user-friendly Telegram bot for cross-chain operations, making DeFi more accessible.
- Decentralized Governance: Launch of a DAO governance protocol to empower the community in shaping the future of STON.fi.
