How fomo Became Crypto's Fastest-Growing Trading App With Crossmint Token Checkout

The Company

fomo is building a trading app for the rest of us—and it's working. In 2026, the app was handling $2.5 billion in trading volume with over 470,000 users, making it the largest cross-chain trading application in crypto.

The app lets users trade across Solana, Base, BNB, and Monad with one balance, discover trending assets, and follow top traders. No new wallets, no bridges, no gas fees.

The Challenge

Crypto's first-mile problem: getting money onchain

fomo had built the best mobile trading experience in crypto. But even the smoothest trading UX doesn't matter if users can't get money into the system.

What fomo wanted to solve onboarding by giving users was the easiest purchase experience ever when buying tokens. Something that had not existed previously. The fiat-to-crypto bottleneck is where most apps lose users. Lengthy KYC flows, wallet setup, bridging between chains, gas fee confusion. Every step bleeds conversion. For trading apps where timing is everything, these friction points are fatal.

fomo needed payment infrastructure that matched the speed of their product:

• Instant access: Users needed to buy trending tokens the moment they discovered them
• Apple Pay support: Give users a familiar checkout experience using familiar payment methods
• Zero friction: No KYC, no wallet setup, no crypto prerequisites
• Global reach: Support for users anywhere, paying with cards they already have
• Cross-chain native: One solution supports every chain fomo needs today and in the future

Traditional payment rails couldn't deliver this. Crypto-native solutions required too much user education. fomo needed infrastructure built specifically for onchain commerce.

The Solution

Fiat-to-crypto infrastructure that converts

When evaluating payment infrastructure partners, fomo wasn't just shopping for a feature—they were looking for a long-term partner. "We wanted to choose a service provider that we knew would provide the stability and long-term partnership that we love the most," says Se Yong Park, CEO at fomo. The ability to work closely with a team that could grow alongside the product mattered as much as the technical capabilities.

fomo integrated Crossmint's payment infrastructure—the same rails that power stablecoin onramps for major trading platforms, fintechs, and enterprises—to create the easiest way to buy tokens with a card.

The impact was immediate.

How it works

A user discovers a trending token on fomo. They tap to buy. Crossmint's payment flow opens—Apple Pay, Google Pay, or card. One swipe. The token lands in their wallet instantly.

No KYC friction. No wallet setup. No seed phrases. No bridging. No gas fees.

Behind the scenes, Crossmint handles everything: payment processing, fraud protection, and token delivery. fomo stays focused on building the best trading experience.

Key capabilities powering the integration:

• Progressive onboarding: Multiple options including no-KYC flows for maximum conversion
• High card authorization: Best-in-class approval rates mean fewer failed transactions
• Chargeback protection: Dedicated anti-fraud team and full dispute coverage
• 197 countries: Global reach from day one
• Instant settlement: Value delivered immediately after payment

The simplicity was the point. "Apple Pay is something that every iOS user uses in their everyday lives. The experience of buying a memecoin is no different from purchasing your morning coffee," says Park. For users with zero crypto experience, that familiarity was everything.

The Results

Weekly active traders jumped 7x within weeks of the integration going live.

The chart tells the story: solving onboarding unlocked a new user segment. fomo's weekly active traders went from 325 to over 2,400 as frictionless fiat-to-crypto payments replaced the old KYC-wallet-bridge gauntlet. In the first week alone, the Crossmint integration drove $570,000+ in trading volume across 9,000+ transactions.

Looking at 2025 to Apr 2026 as a whole, the pattern is clear. Crossmint's payment infrastructure helped unlock a new growth curve—trading volume and user acquisition accelerated dramatically, contributing to fomo crossing $2.5 billion in total volume with 470,000+ users (and adding 3k+ new users a day).

The checkout experience has become one of the strongest parts of the entire fomo app. "Crossmint has been an integral partner in our ability to bring the best social trading experience to new crypto users,” says Park. “They have played a pivotal role in breaking down previous barriers to crypto assets and also in the growth of fomo."

The Bigger Picture

One infrastructure stack, multiple use cases

fomo's integration showcases Crossmint's payment infrastructure optimized for instant token purchases. But the same underlying rails power stablecoin onramps, wallet funding, and payment flows for some of the largest names in fintech and trading.

Crossmint's unified payment infrastructure includes:

• Stablecoin Onramps
  The most seamless way to convert fiat to crypto. Headless APIs or hosted widgets. Full KYC/KYB and AML when required, or streamlined flows for maximum conversion. Used by enterprises and trading platforms moving serious volume.
• Token Checkout
  The same payment rails optimized for purchasing specific tokens—memecoins, NFTs, fungibles. What fomo uses. 10-minute integration.
• Embedded Wallets
  Programmable wallets for users, agents, or backend operations. The same wallet infrastructure powers consumer apps like fomo and enterprise deployments like MoneyGram's stablecoin remittance product.
• Stablecoin Orchestration
  APIs to mint, transfer, and manage stablecoins across 40+ chains. Powers treasury operations, disbursements, and cross-border payments.

The through-line: Crossmint abstracts blockchain complexity so teams can ship faster. Whether you're building a memecoin trading app or a global remittance network, the infrastructure scales with you.
