THE ANALYSIS
Introduction: The On-Ramp Infrastructure Decision
Choosing the right fiat-to-crypto on-ramp is a foundational infrastructure decision impacting user acquisition cost, conversion rates, and compliance overhead.
Sardine takes a different approach by prioritizing fraud prevention and instant settlement through its proprietary behavioral biometrics and AI models. This results in a trade-off between maximum global accessibility and superior security for high-risk segments. Sardine's focus is evident in its sub-1% fraud rate (compared to industry averages of 3-5%) and its ability to provide instant ACH settlement, a key advantage for trading platforms and fintech apps where speed and risk management are paramount.
The key trade-off: If your priority is maximizing user familiarity and broad, global accessibility with a turnkey solution, choose MoonPay. If you prioritize minimizing fraud-related losses, enabling instant settlements for ACH, and serving a US or enterprise-focused user base, choose Sardine. The decision hinges on whether your application values reach or risk management as its primary on-ramp KPI.

CHOOSE YOUR PRIORITY
Decision Framework: Choose Based on Your Use Case
MoonPay for Speed
Verdict: Slower, traditional flow. Strengths: Reliable for standard KYC/AML checks but involves multiple redirects and manual steps. Transaction approval times are dependent on bank processing and user action, leading to potential drop-off. Weaknesses: Not optimized for instant, in-app conversion. The user experience is not seamless for high-frequency or time-sensitive actions like arbitrage or minting limited-edition NFTs.
Sardine for Speed
Verdict: Superior for instant on-ramps. Strengths: Built for sub-second fraud decisioning and instant settlement using direct ACH or card rails. Their Behavioral Biometrics and Synthetic Fraud Models enable real-time approval without sacrificing security. This is critical for DeFi yield farming, gaming asset purchases, and catching NFT drops. Key Metric: Sardine boasts <1 second fraud decisioning versus industry averages of 10+ seconds, directly reducing user abandonment.
MOONPAY VS SARDINE
Technical Deep Dive: Fraud Models and Settlement
A technical comparison of MoonPay and Sardine's core infrastructure, focusing on their divergent approaches to fraud prevention, transaction settlement, and compliance. This analysis is critical for CTOs choosing a fiat on-ramp partner based on risk tolerance and user experience.
Sardine has a more sophisticated, real-time fraud detection system. While MoonPay uses standard KYC/AML checks and third-party data, Sardine employs a proprietary behavioral biometrics and device intelligence platform that analyzes thousands of signals in under 200ms. This allows Sardine to approve more legitimate users while blocking sophisticated fraud that bypasses traditional checks. MoonPay's model is robust but more conventional, focusing on broad compliance.
verdict
THE ANALYSIS
Final Verdict and Recommendation
Choosing between MoonPay and Sardine hinges on prioritizing user experience versus fraud prevention and speed.
MoonPay excels at global user onboarding because of its extensive geographic reach and brand recognition. For example, it supports over 160 countries, 50+ fiat currencies, and integrates with major wallets like MetaMask and Phantom, providing a familiar, seamless checkout flow. This makes it a powerful tool for consumer-facing dApps and NFT marketplaces aiming to capture a broad, international audience with minimal friction.
Sardine takes a fundamentally different approach by embedding real-time fraud detection and compliance directly into its payment rails. This results in a trade-off: while its geographic coverage is more focused (primarily US, Canada, and parts of Europe), its proprietary AI and behavioral biometrics enable instant settlement for 95%+ of transactions. This model prioritizes security and capital efficiency for businesses, drastically reducing chargeback risk.
The key trade-off: If your priority is maximizing global user acquisition with a turnkey, branded solution, choose MoonPay. Its vast network and simple integration are ideal for growth-stage consumer apps. If you prioritize mitigating financial risk, enabling instant settlement, and have a concentrated user base in core markets, choose Sardine. Its fraud-first architecture is critical for platforms processing high-value transactions or operating in regulated sectors like DeFi and centralized exchanges.
