# How Swing Works

### 🔀  **Trade Cross-chain Crypto Assets**

A bridge to every major blockchain ecosystem. Discover the most efficient trading routes. 

Route any crypto asset on any chain to a different crypto asset on any other chain. Swing's cross-chain swap capabilities allows two tokens to be exchanged in a trust-less manner quickly. 

We aggregate bridges and DEX liquidity across every major blockchain including Ethereum, Polygon, Avalanche, Binance Smart Chain, Arbitrum, Optimism, Polkadot, Solana and more.
