Security is never an afterthought at STON.fi — it’s the foundation we build on. That’s why we’re excited to share an important milestone: the initial audit of Omniston’s escrow contracts has been completed, with no critical issues found. Every line of code went through careful review by the TonTech team, giving our community confidence that the infrastructure behind Omniston is secure, reliable, and ready to support the future of DeFi on TON.
Looking ahead, Omniston is more than just an upgrade to how swaps work today — it’s the bridge to tomorrow. Development is already in motion, and the future is closer than it might seem: our engineers are shaping the infrastructure that will connect TON with other blockchains, amplify liquidity, and attract new users. We believe that STON.fi and Omniston will scale TON DeFi and position it as a central hub in the broader world of decentralized finance.
What is Omniston, and Why Escrow Matters
For those new to STON.fi, Omniston is our liquidity aggregation protocol — designed to connect decentralized apps and wallets on TON with the best possible liquidity sources. Instead of developers needing to integrate with multiple liquidity sources, Omniston acts as a single access point, scanning and routing trades across pools to deliver the most favorable rates with minimal slippage.
An escrow in DeFi is a “safety vault” — a smart contract that holds and releases assets only when predefined conditions are met. This ensures that swaps are executed exactly as intended: funds are never moved prematurely, and no participant needs to trust another. In Omniston, escrow logic is what makes token swaps safer, fairer, and fully automated.
The Audit — What Was Checked, and Why It Matters
The audit was performed by TonTech, a team of TON experts supported by TON Foundation, and covered every line of Omniston’s escrow contracts. Specialists performed both automated and manual checks, stress-testing how the contracts behave under different scenarios. The results of this escrow audit are not public, still we may share key takeaways.
The result:
- No critical issues found.
- All logic confirmed to match the intended design.
- Contracts validated as secure, efficient, and ready for production use.
What this means in practice:
- For users: stronger guarantees that swaps will always execute fairly and securely, with minimal risk.
- For liquidity providers: increased confidence in the system, leading to safer yield opportunities and stronger ecosystem adoption.
- For developers: a battle-tested foundation to build on, without reinventing the wheel of liquidity management.
This is a big step in ensuring Omniston remains not only a powerful aggregator, but also a trusted protocol for the TON ecosystem.
Why Audits Are Essential
Smart contracts are lines of code — and code is unforgiving. Even a small error can result in significant losses for participants. Automatic analyzers can catch basic vulnerabilities, but when it comes to high-level logic — ensuring that rules are followed exactly as intended — a professional audit is the only reliable safeguard.
Auditors combine automated analysis with manual review and even mathematical modeling to test contracts against potential exploits. They also check related layers: the dApp interface, resistance to DDoS attacks, and compliance with token standards. In some cases, if developers ignore identified risks, auditors themselves alert the community to prevent losses.
This is why audits are a cornerstone of DeFi security. They detect vulnerabilities, improve efficiency, and ultimately protect users, liquidity providers, and the entire ecosystem.
We’ve made audits a habit at STON.fi. Earlier this year, our STON.fi v2 smart contracts underwent a comprehensive review by Trail of Bits, one of the most respected names in blockchain security. Trail of Bits has audited projects like Ethereum 2.0, Uniswap, Chainlink, MakerDAO, Algorand, and now, STON.fi. Their review covered swap flows, LP math, referral systems, vault logic, and Jetton Standard compliance — confirming that our contracts were hardened before release.
The successful audit of Omniston escrow contracts marks another step forward for STON.fi and the TON DeFi ecosystem. By combining cutting-edge protocol design with independent, rigorous audits, we’re ensuring that innovation goes hand in hand with security.
