Case Study

DeFi App On-Ramp: 340%
Activation Increase

DeFi Yield Protocol - Europe

DeFi

The Challenge

A DeFi yield protocol in Europe was getting a lot of visitors but only 12% of them made their first deposit. The problem was simple. Before users could do anything on the platform, they had to go to Coinbase or Binance first to buy ETH or USDC. Most of them never came back.

Our Solution

Ment Tech team integrated MoonPay as primary provider and Transak as geographic fallback (for Eastern Europe coverage). We connected the platform's existing Sumsub KYC so verified users did not have to verify again. We added Apple Pay and Google Pay for one-tap purchases and built a clean React on-ramp component that matched the platform's brand. The whole thing was live in 3 weeks.

Crypto On-Ramp Integration Use Cases

Every crypto product needs an on-ramp. Here is what we have built.

DeFi Yield Protocol

DeFi App On-Ramp - 340% Activation Increase

A DeFi yield protocol needed to eliminate the 'get crypto first' barrier for new users. We integrated MoonPay + Transak with KYC pass-through from their existing Sumsub verification — new user activation increased 340% within 30 days.

NFT Marketplace

NFT Marketplace - $2.1M GMV in First Month

An art NFT marketplace was losing 90% of buyers because purchasing ETH was too hard. We added a MoonPay widget with Apple Pay. The marketplace did $2.1M in sales in its first 30 days after launch.

Blockchain Gaming

Web3 Game - 60,000 New Players

A blockchain game needed players to buy in-game tokens without being sent to an outside exchange. We built a Transak integration with a Unity SDK and light KYC for purchases under $150. The game brought in 60,000 new players in the first quarter.

Crypto Wallet

Crypto Wallet - $800M Fiat Processed

A self-custody crypto wallet needed a solid on-ramp for card, ACH, and SEPA payments. We built a multi-provider setup using MoonPay, Stripe, and Ramp with smart routing. The wallet processed $800M in fiat volume over 12 months.

Industry Challenges

Why 70% of Crypto Users Never
Complete a Purchase

On-ramp friction is the number one reason people drop off. The good news is it can be fixed in weeks.

Forcing Users Off Your Platform Kills Conversion

When you send new users to Coinbase or Binance to buy crypto first, you lose 60 to 80% of them in the redirect. Users who leave your platform rarely come back.

Card Declines and Bank Restrictions

Many banks block crypto purchases on debit and credit cards without warning. If you only have one payment option and it gets blocked, your user hits a dead end. Around 23% of crypto card transactions are declined at the bank level.

KYC Compliance Creates Friction

Users do not want to verify their identity again if they have already done it on your platform. Without KYC pass-through, every purchase starts a 20-minute identity check that kills conversion.

Single Provider = Gaps in Geographic Coverage

No single provider covers every country and payment method. Platforms using just one on-ramp lock out 15 to 30% of their global users.

Users abandon on-ramp with redirects

23%

Card transaction decline rate

30%

Users locked out by single provider

The Cost of Inaction

Every week without an embedded on-ramp costs your platform 60 to 80% of potential new user sign-ups.

Our Solution

Embedded, Multi-Provider
On-Ramp Integration

Keep users inside your app with a fully branded, globally covered on-ramp. We build the integration layer so it sits right inside your product with no redirects and full brand control. We connect MoonPay, Transak, Ramp Network, and Stripe Crypto at the same time, with smart routing to get the best result for each user.

Multi-Provider Coverage

We connect all the major providers at once and route each user to the best option based on where they are and how they want to pay.

2–6 Week Delivery

We use pre-built provider adapters and integration templates to go live fast, much faster than building in-house.

KYC Pass-Through

Verified users on your platform skip the KYC step at the provider level. This removes friction and can lift conversion by up to 45%.

Full White-Label Control

Your colors, your logo, your domain. We can also build a fully headless API integration so no third-party branding ever shows up unless you want it to.

What's Included in Every Engagement

FAQ

Custom AI Development FAQs

MoonPay is the most widely used provider and covers 160 or more countries with strong white-label options. Transak is better for local payment methods like UPI in India, PIX in Brazil, and SEPA in Europe. Ramp Network is built for DeFi and Web3 apps with broad L2 and multi-chain support. We often use all three together so your users always have a working payment path no matter where they are.
Most single-provider integrations go live in 2 to 3 weeks. A multi-provider setup with KYC pass-through and custom UI usually takes 4 to 6 weeks. We use pre-built provider adapters that speed things up a lot compared to building from scratch. From the first call to production launch, the process is fast and straightforward.
Yes. We set up custom domains, apply your color theme and logo, and can build a fully headless API integration so no third-party branding appears at all. MoonPay and Transak both support custom domain CNAME and CSS theme injection. Your users will see a seamless experience that looks and feels like your product throughout.
Yes. We integrate both on-ramp and off-ramp so users can buy crypto and cash out within the same platform. Off-ramp lets users convert USDC, ETH, or BTC back to their bank account via MoonPay Sell, Transak Sell, or Ramp Off-Ramp. Settlement typically takes 1 to 3 business days depending on the provider and payment method.
We support credit and debit cards, Apple Pay, Google Pay, bank transfer via ACH, SEPA, and Faster Payments, plus 30 or more local payment methods depending on the region. The exact methods available depend on which providers you integrate and where your users are located. With a multi-provider setup, most users will have at least two or three payment options available to them.
If your platform already verifies users through a tool like Sumsub or Jumio, we connect that verification data to the on-ramp provider so users do not have to verify again. This removes a 20-minute identity check that would otherwise kill conversion for returning users. The pass-through is set up in a way that is fully compliant with GDPR and provider data sharing rules. It can reduce on-ramp drop-off by up to 45%.
Yes. MoonPay, Transak, and Ramp all hold MSB and EMI licenses across 50 or more jurisdictions. We configure your integration to meet the specific rules of the regions you operate in, including PSD2 in Europe, VARA in the UAE, and FinCEN requirements in the US. You do not need to hold your own payment license to use these providers.
Between our four main providers, users can purchase assets across 40 or more blockchains including Ethereum, Arbitrum, Optimism, Base, Polygon, Solana, and more. Supported assets include ETH, BTC, USDC, USDT, and hundreds of other tokens. If you need support for a specific token or chain, we check provider coverage and find the best fit during the planning phase.
Yes. Transak and MoonPay both have React Native SDKs for mobile apps. We also support Apple Pay and Google Pay which are natively built for mobile users. The integration works across web, iOS, and Android so your users get the same smooth experience on any device.
We build fallback logic so if one provider or payment method fails, the system automatically tries the next best option. We also set up monitoring dashboards and webhook processors that track failure reasons in real time. Around 23% of crypto card transactions are declined at the bank level, so having multi-provider fallback is essential. We configure retry flows and clear error messages so users always know what to do next.
Yes. If the asset or chain you need is not supported by standard providers, we can build a custom integration using direct bank rails or a purpose-built payment flow. We assess your requirements during the strategy session and map out the best path forward. Most niche asset or chain requirements can be solved with the right combination of providers and custom routing logic.
Provider fees typically range from 1.5% to 4.5% depending on the payment method, region, and provider. Card payments tend to carry higher fees than bank transfers. We give you a full fee comparison across all providers during the planning phase so you can make the right choice for your users and your margins.
