The decentralized finance (DeFi) landscape continues to evolve, and with the rise of high-performance blockchains like The Open Network (TON), innovative protocols are emerging to unlock new possibilities. Among them, STON.fi stands out as a next-generation Automated Market Maker (AMM) protocol built specifically for the TON blockchain. Designed with speed, efficiency, and user experience in mind, STON.fi enables seamless token swaps, deep liquidity access, and advanced DeFi features—all with virtually zero fees and minimal slippage.
Whether you're a casual trader, a liquidity provider, or a developer building on TON, STON.fi offers a powerful suite of tools to enhance your DeFi journey.
👉 Discover how STON.fi is shaping the future of decentralized trading on TON.
What Is STON.fi?
STON.fi is a decentralized AMM protocol native to the TON blockchain. It leverages automated liquidity pools and algorithmic pricing models to facilitate instant token swaps without relying on traditional order books. Unlike centralized exchanges, STON.fi operates without custody over user funds—your assets remain under your control at all times.
Built with simplicity and performance in mind, the platform offers:
- Near-zero transaction fees thanks to TON’s ultra-efficient consensus mechanism
- Low slippage through optimized routing and deep liquidity pools
- Direct integration with popular TON wallets for frictionless access
- Non-custodial architecture, ensuring users retain full ownership of their assets
This makes STON.fi an ideal gateway for both newcomers and experienced users exploring DeFi on TON.
Unlocking Advanced DeFi Features with Omniston
Behind STON.fi’s growing capabilities lies Omniston, a decentralized liquidity aggregation protocol that powers deeper functionality across TON-based applications. By integrating Omniston, developers can supercharge their DeFi apps with access to multi-source liquidity, cross-chain interoperability, and enhanced swap efficiency—all through a single integration point.
Key Features of Omniston
- Cross-chain trustful protocol: Enables secure asset transfers across integrated blockchains without relying on wrapped tokens or third-party bridges.
- SDK for cross-chain operations: Allows any project to embed cross-chain functionality directly into their dApps using STON.fi’s developer toolkit.
- Gasless swaps: Users can pay transaction fees using any supported token—eliminating the need to hold native TON for gas.
- Stableswap routing: Optimizes trades involving stablecoins and synthetic assets using specialized invariant curves, reducing price impact even on large-volume swaps.
- Limit order book: Introduces traditional trading mechanics like limit orders, allowing users to set buy/sell conditions at specific prices.
- Margin trading: Offers leveraged trading capabilities where users can borrow funds against their collateral within the AMM ecosystem.
- DAO governance: A decentralized autonomous organization will govern future protocol upgrades, ensuring community-driven development.
- Telegram bot integration: Brings cross-chain swap functionality directly into Telegram, making DeFi accessible to millions of non-technical users.
These features position STON.fi not just as a swap platform, but as a comprehensive DeFi hub for the TON ecosystem.

Cross-Chain Expansion: Bridging TON with Major Blockchains
One of STON.fi’s most ambitious goals is seamless cross-chain interoperability. The protocol is actively expanding beyond TON to connect with other major networks, starting with TRON and EVM-compatible chains like Polygon.
TON ↔ TRON Integration
Direct swaps between TON and TRON will be possible without intermediaries or wrapped tokens. This trustless bridge eliminates counterparty risk and reduces complexity for users moving assets between these high-throughput networks.
EVM Chain Support
Future updates will integrate support for Polygon and other Ethereum Virtual Machine (EVM)-based blockchains. This opens up access to vast liquidity pools from the broader DeFi ecosystem while maintaining fast settlement times and low costs inherent to TON.
Why Cross-Chain Matters
As DeFi matures, siloed ecosystems become less sustainable. Cross-chain functionality allows users to:
- Access better prices by tapping into aggregated liquidity
- Diversify holdings across multiple chains without relying on centralized exchanges
- Reduce dependency on single-network risks
With STON.fi’s roadmap targeting full cross-chain protocol implementation, users can expect broader asset support and more efficient capital utilization.
Security You Can Trust
In DeFi, security is non-negotiable. STON.fi prioritizes user safety by undergoing rigorous audits from industry-leading firms. The STON.fi v2 smart contracts have been comprehensively audited by Trail of Bits, a globally recognized leader in blockchain cybersecurity. This audit ensures that critical components—including liquidity pool logic, swap mechanisms, and cross-chain messaging—are free from vulnerabilities that could compromise funds.
Additionally, the protocol follows best practices in code transparency and upgradeability, balancing flexibility with security through time-locked governance proposals and multi-signature controls.
