As the Web3 ecosystem expands globally, wallets are no longer just tools for asset storage—they’re gateways to the entire crypto economy. But for new users, especially in emerging markets, the biggest hurdle remains converting fiat into stablecoins like USDT.
In this case study, we explore how a leading Web3 wallet integrated Transfi’s fiat-to-crypto on-ramp, enabling users in 12 countries to convert local currency into USDT with ease.
The Problem: Users Couldn’t Easily Buy USDT with Local Currency
While the wallet provided excellent multi-chain support and strong security features, its user acquisition and retention were hindered by one critical issue:
- Users had no seamless way to acquire USDT using fiat
- Reliance on external exchanges disrupted the onboarding journey
- Many target markets lacked reliable access to stablecoins
This was especially problematic in regions like Latin America, Southeast Asia, and Africa, where crypto adoption is rising, but access to stablecoins remains fragmented.
The Solution: TransFi’s Fiat-to-USDT On-Ramp API
The product team chose to integrate Transfi’s crypto on-ramp, allowing users to buy USDT using local payment methods directly inside the Web3 wallet.
Why Transfi?
- Global coverage: Support for 12 countries at launch, including India, Brazil, Nigeria, Philippines, and Turkey
- Local fiat support: Integration with region-specific payment methods (e.g., UPI, PIX, GCash, M-Pesa)
- Developer-friendly: Pre-built UI widgets, fast onboarding, and flexible API customization
- Compliance built-in: KYC/AML, fraud protection, and regulatory monitoring handled by Transfi
The Integration Process
Within two days, the wallet’s development team was able to:
- Implement Transfi’s Web3 wallet fiat-to-USDT integration via widget
- Customize the flow to match the wallet’s UX and branding
- Go live with fiat-to-USDT support across 12 regions
- Enable instant stablecoin access within the user dashboard
Results After Launch
1. 30% Increase in New Wallet Activations
Users were far more likely to complete onboarding once they could buy USDT directly with local currency.
2. Broader Global Reach
Markets that previously struggled with stablecoin access—such as Kenya, Vietnam, and Argentina—saw a surge in wallet downloads.
3. Improved Transaction Volume
Thanks to easy fiat entry points, daily USDT transaction volume grew by over 45% within the first month.
4. Higher User Retention
Users who acquired USDT via Transfi stayed active longer, often engaging with dApps, DeFi protocols, and NFT marketplaces through the same wallet.
Why Fiat-to-USDT Access Matters for Web3 Wallets
For the Web3 ecosystem to thrive, stablecoin onboarding must be seamless. Many users—especially in volatile economies—prefer USDT as a hedge against local currency devaluation. But without built-in fiat gateways, even the best wallets can lose potential users to centralized exchanges.
This case illustrates how fiat-to-crypto API solutions like Transfi serve as a growth engine for global Web3 apps.
