I was hesitant to use ChangeHero initially, but I’m glad I did! The platform is incredibly intuitive, and the process was so quick. I didn’t even need to register, which saved me time and effort.

This was my first experience of ordering currency on line. give a very good exchange rate so I ordered from them. The whole process was easy and quick. I got relevant up-dates as the order was processed and sent out. From order to receiving the currency it was a week but could have been quicker if I had requested a different delivery date. I would definitely use them again.

Swapping crypto on ChangeHero is simple and takes just a few minutes.
ChangeHero supports 300+ crypto assets for swaps and 150+ for fiat purchases. The simplest way to check availability is to use the search function in the exchange widget on our homepage. You can also browse the full list of supported assets on the Currencies page.
ChangeHero's swap service is available in most countries, except for Prohibited Jurisdictions listed in the Terms of Use. Fiat purchases and sales are processed by our licensed providers — Mercuryo and FinchPay. For country-specific availability, please see https://help.mercuryo.io/ for Mercuryo or https://finchpay.io/faq for FinchPay.
You do not need to create an account or log in to exchange cryptocurrencies on ChangeHero. For fiat purchases, you can optionally create an account with the provider for verification purposes.
The conversion fees depend on the market conditions and available liquidity, but you can expect no more than a 0.5% fee with Best Rate and up to 0.7% in Fixed Rate.
ChangeHero offers two exchange rate options. With Float Rate, the final amount is calculated at the moment your transaction is processed, based on the best market rate available — this means you may benefit from favorable price movements. With Fixed Rate, the rate is locked for 15 minutes from the moment you create the transaction, protecting you from market volatility. Both options are designed to give you the most competitive rate for your crypto swap.
ChangeHero is a non-custodial service and does not hold user funds on their behalf. You retain full control over your private keys at all stages of the exchange process.
For crypto-to-crypto swaps, a small minimum amount may be required to cover blockchain network fees — you'll see a notification in the widget if your amount is too low. There is no hard limit on the maximum swap amount. For fiat purchases, the minimum amount is €25.
ChangeHero works with virtually any cryptocurrency wallet — hardware, software, mobile, or desktop. As long as you have a valid wallet address for the cryptocurrency you want to receive, you can use it with ChangeHero. We also offer built-in integrations with popular wallets such as Exodus, Trezor, Tangem, CoolWallet, and others for an even more seamless experience.
The completion time depends on the networks, with Bitcoin being slower and Solana or BNB Chain faster. For reference, on average, transactions finish within 5 minutes.

Our specialists will review your case individually and assist you with recovery. You can reach support via the live chat on our website, by email at support@changehero.io, or through our official Telegram group.
