# Cross-Chain Swaps

## Cross-Chain swap

Cross-chain swaps are a mechanism that allows the exchange of assets between different blockchain networks without the need for a centralized intermediary. This process enhances interoperability and liquidity across various blockchain ecosystems.

Whereas Decentralized Exchanges (DEXs) can only make swaps on their own blockchain, and bridges can only bridge assets across chains — Mach can create efficient and secure swaps between any two chains, swapping any asset to any other asset. This capability sets Mach apart by offering unmatched flexibility and efficiency in asset exchange.

In practice, this is achieved through the implementation of one single, secure, smart contract per-chain that manages the transfer, ensuring both sides of the transaction are completed simultaneously and securely. By utilizing leveraging each respective chain's underlying security, it guarantees that the swap process is trust-less and efficient.
