By Web3 is no longer a single-chain experience. Users swap tokens, farm yields, and move liquidity across dozens of networks every day. That’s why cross-chain bridges have become one of the most vital elements of decentralized finance (DeFi).
And in 2025, one ecosystem stands out for its explosive growth and unique community — The Open Network (TON), deeply integrated with Telegram and rapidly evolving into a mainstream blockchain hub.
As TON attracts new DeFi protocols, NFTs, and Web3 wallets, cross-chain connectivity becomes critical. Let’s explore how TON bridges work, compare the top five players — including the highly practical Defiway — and see where the future of interoperability is heading.
Why Cross-Chain Bridges Are Essential for TON
TON started with a clear mission: bring blockchain utility to billions of Telegram users. Fast, scalable, and user-friendly, it’s designed for real-world adoption — but that vision only works if users can easily move value between TON and the rest of the crypto world.
Bridges solve that.
They allow assets such as USDT, ETH, BTC, or BNB to move seamlessly into TON.
Without bridges:
- TON dApps would remain isolated from DeFi liquidity
- traders couldn’t swap or farm cross-chain
- and developers would struggle to onboard users who hold assets elsewhere
In short, bridges are TON’s lifelines to global liquidity.
What Defines a Reliable Cross-Chain Bridge?
Not all bridges are equal. Some offer blazing speed but poor security; others are audited and decentralized but clunky to use. To pick the best TON bridge, users and developers should evaluate the following:
| Factor | Why It Matters |
| Security & Audits | Prevents exploits (bridges have been hacked for billions). |
| Decentralization | Reduces reliance on a single custodian or relayer. |
| Liquidity Depth | Ensures large transfers clear without slippage. |
| Fees & Transparency | Predictable, fair pricing builds trust. |
| Speed | Minimizes waiting times for confirmations. |
| Supported Chains | Multi-chain flexibility for real interoperability. |
| User Experience | Simple, intuitive, and clear progress tracking. |
With that framework, let’s dive into the top bridges connecting TON to the multi-chain universe.
Top 5 TON Cross-Chain Bridges (Updated for 2025)
1. Symbiosis Finance
Symbiosis uses a liquidity-pool-based bridging system, rather than the traditional lock-and-mint model. It combines speed and efficiency with decent decentralization.
Highlights
- Supports a wide range of EVM and non-EVM chains
- Swap-style bridging: users don’t need identical token representations
- Smooth and polished UX
Limitations
- Pool liquidity can fluctuate, affecting slippage
- Impermanent loss risks for liquidity providers
- Some routing logic still semi-centralized
Verdict
For frequent cross-chain traders and TON DeFi users, Symbiosis is a high-performance choice that prioritizes cost efficiency and user flow.
2. Defiway Bridge
Defiway Bridge has rapidly become one of the most practical options for users looking to move assets between TON and other major chains like Ethereum, BNB, Polygon, Tron, and Solana.

- Audited by CertiK: adds an extra layer of assurance
- Fast transaction finality: typically within minutes
- User-first design: clean, simple interface for retail and business users
Trade-offs
- Centralized relayer model (not yet fully decentralized)
- “Unlimited volume” claims should be read as marketing, not literal
Verdict
Defiway strikes an excellent balance between convenience, cost control, and reliability. Its combination of speed, fixed fees, and multi-chain flexibility make it arguably the best all-around TON bridge for both beginners and experienced DeFi users.
3. TON Bridge (Official)
Developed under TON Foundation oversight, the TON Bridge enables secure transfers between TON and Ethereum or BNB Chain.
Advantages
- Official, foundation-backed infrastructure
- Ideal for moving native TON and wrapped tokens
- Transparent operation and verified smart contracts
Limitations
- Only supports a few major chains
- Narrow token coverage compared to competitors
- Upgrade cycles are slower (for safety reasons)
Verdict
Best for users who prioritize trust and simplicity over flexibility — particularly when handling TON native assets or integrating directly with official wallets.
4. Rubric Exchange
Rubic isn’t just a bridge — it’s an aggregator of bridges. It automatically finds the most efficient route for your token transfer across dozens of chains and protocols.
Pros
- Aggregates multiple bridges for best rate
- Supports swaps, not just token transfers
- Great time saver for advanced users
Cons
- Extra complexity adds potential latency
- Hidden aggregator fees may apply
- Depends on third-party bridge uptime
Verdict
Rubic shines when you want automation and optimization. Think of it as a “search engine” for cross-chain routes, including TON paths.
5. SimpleSwap
SimpleSwap takes the no-frills approach — one interface for thousands of coins and multiple chains.
Pros
- Beginner-friendly UX
- Huge token selection
- No registration required
Cons
- Less transparency on backend routing
- Not ideal for large-volume swaps
- Limited control over bridge selection
Verdict
A solid choice for newcomers and one-time users who want speed without complexity.
Additional Bridges in the TON Ecosystem
According to TON’s official bridges directory, more advanced interoperability tools are emerging fast:
- Stargate Finance – deep liquidity for stablecoins
- Rhino.fi – L2-compatible bridge covering Arbitrum, Base, TON, and more
- Layerswap – direct exchange ↔ chain swaps, ideal for moving from CEX to TON
- Meson.fi – optimized routing engine with liquidity-first design
- Retro Bridge – simple UI, growing multi-chain coverage
- TON Teleport – experimental Bitcoin ↔ TON connector
Together, they’re building a multi-bridge mesh around TON — redundancy that increases reliability and decentralization.
Security and Risk Perspective
Bridges are the most attacked infrastructure in crypto.
From 2021–2024, over $4.3 billion was stolen through bridge exploits. Most incidents involved faulty message relays, insufficient validation, or compromised multi-sig setups.
Modern research shows growing progress in threat detection:
- ABCTRACER: maps cross-chain money flows with 91 % trace accuracy
- BridgeShield: machine-learning model achieving 92 % F1 score for exploit detection
For TON bridges, these studies reinforce one message — auditing is not enough. Continuous monitoring, fail-safes, and real-time analytics must become standard practice.
Defiway and Symbiosis have taken steps in that direction by providing public audit reports and visible transaction tracking, but the ecosystem still needs open-source validators and circuit breakers to reach institutional-grade safety.
Future-Ready Innovations in Cross-Chain Design
- Zero-Knowledge (ZK) Bridges
Using zk-proofs to verify state changes across chains without trusted intermediaries — potentially the gold standard for secure interoperability.
- Cross-Chain Messaging
Moving beyond token transfers to executing smart-contract calls between chains. This unlocks multi-chain DeFi logic.
- Layer-2 Awareness
As rollups mature, TON bridges must natively connect to Arbitrum, zkSync, Base, and Optimism.
- Aggregator Networks
Unified routing layers that select between Defiway, Symbiosis, and Stargate dynamically based on liquidity, cost, and latency.
- Validator Markets
Decentralized relayers with staking/slashing incentives, reducing single-point-of-failure risk.
- Compliance-Optional Modules
Opt-in KYC for institutional transfers — without compromising core decentralization.
Choosing the Right TON Bridge: Practical Guide
Here’s a simple framework for decision-making:
