Is STON.fi Safe?

|DEX
C+

Risk Grade: C+ (37/100)

STON.fi is rated as elevated risk — multiple novel mechanisms and notable interaction risks.

STON.fi is the clear market leader on TON with strong institutional backing, but its fate is inseparable from the Telegram-TON ecosystem. The Omniston cross-chain vision is ambitious, and the Trail of Bits audit provides baseline security confidence. However, the concentrated ecosystem dependency and significant unreleased token supply create material risks.

STON.fi is the leading decentralized exchange on the TON blockchain, deeply integrated with the Telegram ecosystem. Users can swap TON-based tokens, provide liquidity to earn trading fees, and farm STON token rewards. With over $6 billion in all-time trading volume and 28 million transactions, it dominates TON DeFi. The protocol raised $9.5M in Series A funding from Ribbit Capital and CoinFund in July 2025, and is building Omniston, a cross-chain aggregation protocol for bridgeless swaps. Smart contracts are audited by Trail of Bits with active bug bounty programs through Certik and HackenProof.

Key Risks for STON.fi Users

1.

STON.fi is deeply dependent on the Telegram-TON ecosystem — regulatory action against Telegram could disrupt access to the entire platform.

2.

63% of STON tokens are still locked and will vest to early investors, creating future sell pressure risk.

3.

TON blockchain's unique architecture means security tooling and auditing practices are less mature than for EVM chains.

Top Risk Factors

  • STON.fi is deeply tied to the TON blockchain ecosystem, which is uniquely dependent on Telegram's continued integration and support — regulatory action against Telegram could cascade to all TON DeFi.
  • Only 37% of STON tokens are currently circulating from a 100M supply. Future token unlocks for team and investors could create substantial sell pressure on relatively thin TON DEX liquidity.
  • The Omniston cross-chain aggregation protocol promises bridgeless swaps across multiple blockchains, but this novel architecture introduces untested cross-chain settlement risk.
