Mercuryo Frequently Asked Questions

What is the On and Off-Ramp?

A must-have tool for businesses that need fast crypto-to-fiat conversion on their websites. On-Ramp lets users buy crypto, while Off-Ramp converts it to fiat and withdraws it to Visa or Mastercard — all within minutes. Built for Web3 apps, wallets, exchanges, and fintech platforms. 

Can you customize the On and Off-Ramp?

There are many options you can choose from to build the tool your business needs. 

For example, in UX, you can enable features like silent login (no email prompt), KYC sharing (no repeat verification on Mercuryo side), passkey, or recurring payments. 

The widget’s appearance can be fully themed to match your product’s look and feel, including colors, fonts, text, and your logo on the login screen. 

Check all the options here.

About Mercuryo's fees, payment methods, and geo-coverage.

Mercuryo fees are dynamic and depend on factors like the selected payment method, user location, and network fees (e.g., blockchain gas). More can be found here. The exact fee is always there in the widget before payment confirmation. 

Available payment methods can be found here, whilst here is the list of countries we do not operate in. 

What fiat and crypto does Mercuryo support?

We support all major fiat currencies and leading Layer 1 and Layer 2 blockchain assets, which you can view here and here. 

What are Mercuryo's transaction limits?

You can view our transaction limits here. 

How does the verification process work in Mercuryo?

Even if users have already been verified on your platform, they’ll still need to complete Know Your Customer verification. Mercuryo does this independently, as a licensed merchant of record legally required to conduct its own checks. 

Standard KYC is required if the total amount exceeds €700 or if any anti-fraud or AML flags are triggered. In this case, the user will need to prepare an ID, complete a selfie check, and submit proof of address (e.g., utility bill or bank statement). 

Light KYC applies if the total amount is under €700 and no suspicious behavior is detected. However, even under Light KYC, the system may request full verification at any point based on risk-based logic. 

KYC Sharing (KYC-share-token) is possible if your platform has already verified the user via Sumsub. In that case, we can accept the shared token and skip the full KYC process. 

Finally, returning users who have already completed KYC with Mercuryo won’t need to verify again. 

Who will provide support to users in case of transaction issues?

It’s on us. Users can access 24/7 chat support and get a response within a few minutes. We encourage all users to contact us through our live chat in our product for the best experience, but we also offer email support too.

Are Mercuryo partners protected from chargebacks?

We take full responsibility for all chargebacks, fraud, and disputes as the merchant of record — no worries. 

How to integrate Mercuryo for the On and Off-Ramp?

You need to follow these steps, but not alone — your integration manager will support you along the way: 

1. Sign up and request access
2. Get sandbox keys to start testing immediately
3. Pay rollover deposit for the service based on the pricing you chose, and get a link to pass the KYB process
4. Complete KYB (typically takes ~1 week)
5. Receive production keys and go live 

Is there any technical documentation for integration?

Here are the guides for Redirect and for the Iframe.

Does Mercuryo sell something other than crypto?

Mercuryo’s On-ramp is designed only for purchasing cryptocurrencies and doesn't support direct sales of physical goods or services. If you’re interested in enabling NFT sales, please reach out to our sales team to join the waitlist for our upcoming dedicated NFT checkout solution. 

Can Mercuryo partners earn any affiliate commission?

Absolutely! You’ll see your earnings in real time on your dashboard. Payouts are made in crypto, become available once you reach 1,000 USDC, and you can manage them through the dashboard. 

What is Mercuryo's KYB Procedure?

To complete the Know Your Business (KYB) process, your company needs to submit a short questionnaire and a set of verification documents via the KYB link provided by your Sales Manager. 

Here’s what it takes: 

• A brief form to provide key business information
• An official document listing current directors, shareholders, and UBOs (Ultimate Beneficial Owners) *
• A screenshot from your domain registrar or admin panel confirming ownership (person or company name) Please see an example here.
• Sumsub verification for Directors, Shareholders, and UBOs. Each person will need to share name, nationality, address, a valid government-issued ID, and recent proof of address (e.g., utility bill, bank statement, or tax return) 

All documents must be issued within the last 3 months. 

Does Mercuryo provide support for partners?

Yes! During onboarding, our sales manager and technical team will guide you via live chat, email, or video calls. And after the launch, you’ll be assigned a dedicated success manager and a marketing lead to support you on the way. 

Can Mercuryo partners list their personal tokens?

It is possible. We can enable seamless purchases of your token directly from your platform and make it available across a network of 200+ partners, including MetaMask, Trust Wallet, and Ledger (subject to partner approval). 

We can also make your token accessible to users in 135+ countries via 10+ payment methods, including Apple Pay, Google Pay, Revolut Pay, and other local options. 

There are some listing criteria: 

• Listed on a Tier-1 exchange (like Kraken or Binance)
• Market cap of at least $300M or in the Top 100
• Clear whitepaper, working product, and open technical documentation
• Strong legal, compliance, and KYC standards * Demand from end users and no ongoing regulatory investigations 

Listing process: 

1. Submit your request to your sales manager
2. Our team will conduct a technical, legal, and compliance review
3. If approved, we will initiate integration planning and timelines 

Can partners resell Mercuryo’s solution to other businesses?

You may offer Mercuryo’s solution to third-party businesses only after they’ve been approved by us. Each merchant will go through a standard KYB process. You can find the KYB requirements in this FAQ.
