What is a Crypto Wallet?

A crypto wallet is a self-custody tool that functions as a browser plug-in or mobile app. With self-custody, you hold your cryptocurrency directly using a public-private key pair, similar to storing cash in your own safe, rather than relying on an online account. It allows for easy, direct transactions with anyone around the world.

Is Helio Supported on Mobile Devices?

Yes, Helio is fully compatible with both iOS and Android. It also integrates seamlessly with mobile crypto wallets including deep-link support.

Refunds & Disputes

How Can I Get a Refund? Can Helio Help?

For refunds, please contact the merchant directly, as all transactions made on the Helio platform are direct peer-to-peer payments. Once a payment is made, it cannot be reversed or reclaimed by Helio due to the blockchain's security and irreversible nature. Therefore, Helio is unable to resolve payment disputes.
