Changelly is an instant cryptocurrency exchange service (also called a "swap" or "aggregator") designed for fast and straightforward crypto-to-crypto and crypto-to-fiat transactions. Here's how it works and what makes it useful:

🔄 How Changelly Works

• Aggregates liquidity from multiple crypto exchanges and liquidity providers to offer users competitive exchange rates without order books or matching.
• Infinity of altcoins—supports hundreds of cryptocurrencies, so you can swap assets like Bitcoin, Ethereum, Solana, and many lesser-known tokens.
• No mandatory account creation for small trades—just enter your email and wallet address. But larger transactions or fiat purchases will trigger identity verification (KYC/AML).
• Two main services:
  1. Crypto-to-crypto swaps—instantly exchange one token for another.
  2. Crypto-to-fiat purchases—buy crypto using bank cards via integrated partners.

💰 Fees & Rates

• Changelly typically charges a fixed service fee (around 0.25%) plus a margin built into the exchange rate.
• Fiat purchases add fees on top (including third-party provider and credit card charges).
• No hidden fees—they clearly display the total amount before you confirm the swap.

✅ Advantages

• Speed & convenience—very fast, with no limit order waiting or manual order books.
• Wide asset selection—great if you're looking to swap niche tokens easily.
• Minimal setup—no full sign-up required for most crypto-to-crypto swaps.

⚠️ Considerations

• Slightly higher effective rates than major centralized exchanges due to aggregated pricing and fees.
• Limited features—does not support advanced trading tools like limit orders, margin, charting, or derivatives.
• Third‑party fiat integration—costs and speed depend on external payment processors.
• Non-custodial, but safety matters—you must ensure you're using the official website/app, and always double-check destination addresses since crypto transactions can't be reversed.

Summary

Changelly excels in providing fast, hassle-free crypto swaps and card-based crypto purchases. It's ideal if you need a quick, one-off exchange or want access to lesser-known tokens without jumping through account-verification hoops. But if you're an active trader looking for advanced tools or the best rates, centralized exchanges (like Binance, Coinbase, Kraken) may better suit your needs.
