# Intro

Cross-chain payments enables your customers to buy an NFT with crypto tokens - even if the tokens aren't native to your chain!

For example, a user can buy an ETH NFT with SOL tokens with cross-chain payments!

Why use cross-chain payments?

* Free for sellers/platforms
* No KYC
* Saves buyers from fees (gas fees to transfer to an exchange, exchange fees, etc)
* Increases conversion rates for buyers (easier for NFT buyers!)
