# Chain support

## 🌐 Supported Chains

SwapNet operates across multiple blockchain ecosystems. The chains listed below are current as of September 2025. For the most up-to-date list, visit our `/chains` endpoint (see [supported chains](/docs/aggregator-api/chains.md)).

### **EVM Chains**

* Ethereum
* Base
* ArbitrumOne
* HyperEVM
* Unichain
* Bsc
* Polygon
* Optimism

* Katana

### **Non-EVM Chains**

## 🚀 Chain Expansion

We continuously expand our chain support based on both users requests, and our own operational needs.

New EVM chain support typically takes one week or less to implement, while non-EVM chains might take longer.

To request support for a new blockchain:

* **Email**: [info@swap-net.xyz](mailto:info@swap-net.xyz?subject=Request%20for%20chain%20support)
* **Telegram**: Reach out through [our official Telegram channel](https://t.me/swapnetxyz)

### ⚡ Low Cost Mode

For chains with limited user activity, we offer **Low Cost Mode** to keep fees minimal:

* Liquidity data is fetched on-demand when a swap request arrives
* Response time is slightly slower (\~1 second)
* Enables cost-effective support for niche chains
