# Changelly > Exchange any crypto instantly. Changelly is a non-custodial cryptocurrency exchange platform. It aggregates rates across exchanges to let users swap, buy, and sell crypto, and offers API and on/off-ramp tools for wallets, exchanges, and token projects. Changelly is a cryptocurrency exchange platform that provides instant crypto swaps, fiat to crypto purchases, and decentralized exchange aggregation. It sources rates from multiple centralized and decentralized venues to find competitive pricing. The platform serves individual retail users as well as businesses such as wallets, exchanges, and token projects that integrate its exchange functionality. The service operates on a non-custodial basis, so it does not hold user funds; assets are sent directly to the user's wallet once a swap completes. Users can choose fixed or floating rate exchanges depending on tolerance for price changes during processing. Fiat purchases and sales are handled through partner payment providers, letting users buy or sell crypto with bank cards, transfers, and other common payment methods. Changelly's consumer offerings include its instant exchange, a buy and sell service covering multiple fiat currencies, and a decentralized swap aggregator. For businesses, it provides exchange and fiat on and off ramp APIs, embeddable widgets, and token listing services for integrating exchange functionality into third-party platforms. It is used by individual traders alongside wallets, exchanges, and crypto projects that need exchange infrastructure. - Type: Company - Sector: Finance - Status: Active - Founded: 2015-04-01 - Profile: https://thegrid.id/profiles/changelly ## Products - [Changelly Exchange](https://thegrid.id/profiles/changelly): Changelly Exchange is a centralized exchange that aggregates cryptocurrency rates across partnered trading platforms to facilitate instant cross-chain swaps.
