10x in 12 Months: How MiniPay Scaled Stablecoin Payments with Transak

Transak helped MiniPay achieve 10x transaction growth (GTV) and 2.5x conversion improvement in 12 months.

Partner: MiniPay (by Opera)

Industry: Mobile Payments / Stablecoins

Primary Use Case: Fiat-to-Stablecoin On-Ramp (USDC & USDT on Celo)

Period: March 2025 – February 2026

The Challenge

MiniPay is a mobile-first stablecoin wallet by Opera that promises to let anyone convert local currency into USDC or USDT and use it for payments, savings, transfers, and more.

But scaling that promise came with real friction. 

MiniPay needed a payments infrastructure partner that could handle fiat-to-stablecoin conversion across dozens of countries and payment methods, while keeping the user experience fast, intuitive, and compliant. Early on, gaps in regulatory coverage (particularly across U.S. states) and limited payment method support were creating drop-off and restricting growth in key markets.

The challenge was about building conversion confidence, i.e., ensuring that when a user tapped “Buy Crypto,” they actually completed the purchase.

Why MiniPay Chose Transak

MiniPay’s decision to incorporate Transak as an on-ramp partner boiled down to five factors:

• Regulatory Coverage: We are a regulated infrastructure provider in key markets such as the US, UK, AU, EU, and more.
• Global Payment Method Coverage: We support global payment methods like Apple Pay, Credit/Debit Cards and Bank Transfers.
• Stablecoin Liquidity Infrastructure: We reliably source liquidity for USDC and USDC on Celo Network for users.
• Compliance and Risk Monitoring: We implement partner-specific optimizations to mitigate fraud and risk.
• Ongoing Conversion Optimization: A dedicated account management team shares data, flags issues, and helps improve funnel performance.

The Solution

MiniPay integrated Transak to offer users an option for seamless fiat-to-stablecoin path inside the app. Over time, the integration expanded well beyond a standard API connection.

Our contribution to MiniPay’s on-ramp stack centered on three areas:

1. Broad Regulatory Coverage: We enabled USDC and USDT purchases on the Celo network across a wide range of U.S. states through our money transmitter licenses and external partnerships, as well as coverage across Europe, and parts of Asia-Pacific.
2. Multiple Payment Rails: Users can pay via credit/debit card, Apple Pay, SEPA bank transfer, and other payment methods.
3. Flexible Pricing Architecture: Our infrastructure supports customizable fee structures, allowing MiniPay to tailor the cost experience for its users and reduce friction at checkout.

How We Worked Together

This wasn’t a set-it-and-forget-it integration. We assigned a dedicated account management team that has worked with MiniPay continuously since launch.

• Coverage Expansion: MiniPay discovered that several U.S. states were not being served due to licensing gaps. We were able to bridge that gap throughout 13+ U.S. MTLs and external partners for other states where MTLs were due.
• Data-Driven Optimization: We shared ongoing conversion analytics, helping MiniPay identify and address drop-off points. Our team monitored conversion funnels, flagged anomalies, and recommended optimizations that contributed to a sustained upward trend in completion rates.
• Token and Network Enablement: We enabled both USDC and USDT on the Celo network, giving MiniPay users token flexibility while staying on a low-cost, fast-settlement chain.
• Risk and Compliance Monitoring: We continuously optimized fraud and risk parameters specific to MiniPay’s user base, balancing security with conversion performance.

The Results

Over 12 months of partnership, the impact compounded month after month.

Transaction Volume

Transak-powered transactions grew approximately 10x between May 2025 and February 2026, with eight consecutive months of all-time high GTV from July 2025 onward.

Conversion Rate

The share of users who tapped “Buy Crypto” and completed a purchase rose 2.5x in 12 months driven by expanded coverage, additional payment methods, and ongoing funnel optimization.

User Retention

59% of users who completed a transaction came back to transact again within the 12-month window, indicating strong trust in the on-ramp experience.

Stablecoin Adoption

Virtually 100% of transactions were in stablecoins (USDC and USDT), split nearly evenly between the two tokens, underscoring MiniPay’s positioning as a digital-dollar wallet.

Global Reach

While the U.S. remained the largest market, meaningful volume came from across Europe countries such as Germany, France, Poland, and Spain, which demonstrates the breadth of Transak’s reliable payment coverage.

Payment Method Breakdown

Across Transak-powered orders, credit and debit cards dominated as the primary payment method, followed by Apple Pay and SEPA bank transfers.

What’s Next

Upcoming initiatives include expanding into new regions and further optimizing conversion through data-driven insights.

As stablecoin adoption accelerates globally, the partnership with MiniPay remains a key part of how users access digital dollars across markets and payment methods.
