What is Mercuryo? A hybrid solution for connecting fiat and crypto
While non-custodial wallets like MetaMask or Trust Wallet focus on autonomous private key but don't natively support fiat currencies, Mercuryo offers an integrated approach. The platform acts as both a currency conversion service and a temporary storage tool for funds, simplifying digital asset management for all types of users.
What is Mercuryo Key features
Mercuryo 's unique feature lies in its ability to bring together several functions within the same environment:
- Instant conversion: Allows you to quickly convert fiat currencies (euros, dollars, etc.) into cryptocurrencies (Bitcoin, Ethereum, etc.) and vice versa, without multiplying interfaces.
- Custodial portfolio management: Funds are temporarily stored by the platform, eliminating the need for the user to directly manage their private keys.
- API integration and widget: Facilitates the incorporation of the service into dApp or other Web3 , thus offering a turnkey solution for businesses.
- Integrated KYC : Identity verification is performed to ensure compliance with regulatory standards and secure transactions.
- Mastercard debit card: Thanks to their partnership , users can spend their converted assets directly at over 100 million points of sale.
What is Mercuryo The need for integrated conversion within the crypto ecosystem
cryptocurrency landscape , many users hold non-custodial wallets to gain complete control over their assets. However, these tools don't allow for the integration of fiat without relying on an external service. This results in a fragmented user experience, requiring the use of another application (usually a centralized exchange) to buy, sell, or convert assets.
Mercuryo addresses this gap by offering an interface where these conversion operations can be performed in just a few clicks. This results in a significant reduction in transaction friction and improved accessibility.
What is Mercuryo Practical use of the service in a wallet
Let's take the case of Julien, a user who has a Ledger wallet to store his cryptocurrencies . He wants to buy ETH using his bank card , without going through a centralized exchange like Binance or Coinbase , and receive the funds directly to the Ethereum of his Ledger .
Julien opens the Ledger Live , which is the official management interface for the Ledger . In the "Buy/Sell" , he selects the "Buy Crypto" . He begins by:
- Select the cryptocurrency — here, Ethereum (ETH).
- Choose the amount he/she wishes to buy (for example, 150 euros).
- Specify the payment method: bank card, SEPA transfer, other…
At this stage, Ledger Live offers the user a list of payment service providers based on their location, fees, and processing times. Examples of these providers include MoonPay , Banxa , Coinify , and Mercuryo .
Julien selects the option that best suits his needs by comparing conversion rates and fees. He is then redirected to an interface integrated directly into Ledger Live, without leaving the application. He enters his bank card information, verifies his identity via the KYC if it's his first time using the service, and confirms the purchase.
A few minutes later, the ETH were credited directly to his Ledger Ethereum address . No account creation on an exchange, no intermediary transfer from a centralized platform: the purchase was made in a few clicks, with the assurance that the funds arrived safely in his non-custodial wallet .
Mercuryo 's role : to offer a fiat-to-crypto gateway , directly accessible from a personal wallet. Thanks to this approach, users retain control of their assets while enjoying direct access to conversion services , without having to leave their wallet ecosystem.
Fees applied: the price of simplicity
Services like Mercuryo , MoonPay , and Banxa offer a fast and integrated solution for buying cryptocurrencies directly from a non-custodial wallet , without going through a centralized exchange platform. This simplicity comes at a price. The fees charged by these providers are generally higher than those found on traditional exchanges
Let's take an example: for a purchase of 150 euros worth of Ethereum , a service like Mercuryo typically applies:
- Transaction fees range from approximately 0.95% to 3.5% depending on the payment method (card or bank transfer).
- A margin on the conversion rate that can be as high as 1-2% compared to the market price,
- network fees , which vary depending on the blockchain used.
Conversely, a user who buys the same amount of cryptocurrency on a centralized exchange like Bitvavo, Binance , or OKX will pay:
- Very low transaction fees (often between 0.1% and 0.4% depending on the user's level),
- Fees for the on-chain transfer to your external wallet (usually a few cents to a few euros depending on the blockchain, if possible avoid Ethereum ).
Overall, using a CEX and transferring funds to a Ledger wallet is often less expensive , especially for larger amounts. However, it requires more steps, from creating an account to setting up the withdrawal, which can be a drawback for beginners or those seeking an immediate and seamless solution.
In summary, with providers like Mercuryo , the user pays an additional intermediary in exchange for a simplified and direct experience : no need for an exchange , no manual transfers to manage, and no risk of address errors. This makes it a particularly attractive option for quick purchases, for getting started with cryptocurrencies , or for direct integration into a dApp or mobile wallet .
Technical operation and infrastructure
Mercuryo 's robustness relies on a technical infrastructure designed to manage conversion and transaction operations in real time. The following technical points illustrate this performance:
- High-performance API: The programming interface allows partners to easily connect the service to their platforms, ensuring a constant and secure data flow.
- Multi-chain support: The platform is compatible with various standards, including ERC-20, BEP-20 and other blockchain protocols, ensuring the interoperability essential for converting multiple assets. It currently supports just under fifty assets .
- Automated process: The conversion system relies on real-time pricing algorithms.
- Compliance controls: KYC protocols are integrated to ensure regulatory compliance.
Conclusion: What is Mercuryo?
Ultimately, Mercuryo is a solution that connects the fiat world and the cryptocurrency space. It allows users to access conversion and payment services through an integrated interface. This positioning, comparable to that of MoonPay, is distinguished by a simplified user experience, facilitating integration with custodial wallets to offer both the purchase of cryptocurrencies and the practical use of funds via a debit card.
For those already using non-custodial wallets and looking to bridge the gap between digital asset management and traditional currency transactions, Mercuryo is an option worth exploring. By combining fiat-to-crypto conversion, temporary storage, and payment integration on a single platform, it offers a simple and efficient alternative to the more fragmented solutions currently on the market.
