Changelly is an instant cryptocurrency exchange and swap service that allows users to quickly convert one crypto asset to another without creating an account (though it also offers account-based features). Here’s what makes it stand out:

• Wide coin support: You can swap between hundreds of cryptocurrencies — from major ones like Bitcoin and Ethereum to many altcoins.
• No order book: Unlike centralized exchanges, Changelly aggregates multiple trading platforms and liquidity providers to offer a single best exchange rate, executing swaps automatically.
• Fiat integration: You can buy crypto with credit/debit cards through integrated third-party payment providers.
• User-friendly interface: Designed for simplicity — you enter the amount and the destination address, and Changelly handles the rest.
• Regulation & KYC: Basic swaps under certain thresholds often don’t require identity verification, but larger transactions (especially fiat-related) will trigger KYC checks.

Is it secure?

Changelly is widely used and has built a solid reputation for safe, user-friendly crypto swaps. However, as with any non-custodial service, pay attention to:

1. Double-checking wallet addresses – transactions are irreversible.
2. Comparing rates and fees – their convenience may come at a premium.
3. Using official platforms only – phishing sites posing as Changelly have appeared before.
