Mercuryo, a crypto payments firm, has unveiled a Mastercard debit card for European crypto holders. The virtual card, named Spend, lets users convert crypto to fiat for purchases.

It's available across the EU. Users can buy stuff at over 90 million Mastercard merchants.

Polish fintech Quicko issues the card. Mercuryo aims to make Spend widely accepted.

"Spend's launch is a big deal for us," says Petr Kozyakov, Mercuryo's co-founder and CEO. He's pretty chuffed about it. "It's a step towards making crypto more mainstream."

The card works with a non-custodial wallet. Users keep their crypto keys. It supports 40 cryptocurrencies, including Ethereum and Solana. No word about Bitcoin, though.

Mercuryo claims instant conversion from crypto to fiat. No waiting around like with banks.

For now, it's just for the European Economic Area. But they're planning to roll it out globally soon.

The card has a €40,000 monthly limit. There's a €1.60 issuance fee and a €1 monthly maintenance fee. Users gotta follow anti-money laundering rules.

Mercuryo isn't the first to launch a crypto-to-fiat card. MetaMask did it in August with Mastercard. Bybit's been offering one since last year.

It's a crowded field. But Mercuryo's betting on its competitive fees and security to stand out. Time will tell if they've got what it takes to make a splash in the crypto payments world.
