If a fiat (EUR) to crypto swap fails, will the EUR be automatically refunded to my bank account?

Yes! Fastspot and OASIS are fully automated systems. The fiat money (EUR) you sent will be automatically refunded to your bank account. Always remember: Since Fastspot is using atomic swaps, the swap either happens as planned or it is reversed after timing out or failing and both swapping parties automatically retrieve their assets. Depending on what issue led to the time-out or failure of the swap, funds will automatically be refunded within 5 business days. For the very unlikely event of an unexpected system outage, please keep the displayed swap ID for reference.
