Nansen adds search feature for 200,000 FOMO wallets on Solana and Base

Nansen just made it significantly easier to peek at what the most active social traders are actually doing with their money. The blockchain analytics firm has rolled out a search feature covering more than 200,000 wallets linked to FOMO, the mobile-first copy-trading app that’s been quietly eating market share on Solana and Base.

Users can now pull up detailed holdings, trade histories, and profit-and-loss data for FOMO-connected wallets directly through Nansen’s platform.

What the integration actually unlocks

The update goes beyond surface-level wallet tracking. Nansen’s integration includes FOMO-associated addresses that aren’t even visible within FOMO’s own app interface, which means the analytics capture a more complete picture of how these traders are operating across chains.

With more than 500 million labeled wallets already in its database, Nansen has been building toward this kind of granular, protocol-specific profiling for a while. Adding a concentrated batch of 200,000 wallets from a single, high-activity platform gives analysts a dense cluster of trading behavior to study rather than scattered data points across the broader ecosystem.

FOMO’s rapid rise

FOMO launched around May 2025 as a non-custodial copy-trading platform with a focus on mobile users. The app supports gasless swaps across multiple chains, lowering the friction that typically keeps casual traders from engaging with on-chain markets.

The growth trajectory has been steep. The platform has processed billions in cumulative trading volume since launch. In 2026, FOMO reported an all-time high weekly revenue of $264 million, placing it among the top revenue-generating protocols in the Solana ecosystem.

Those numbers attracted serious capital. FOMO closed a $75 million Series B funding round in June 2026, bringing total funding to approximately $94 million.

Why this convergence keeps accelerating

Nansen’s move reflects a broader trend in crypto infrastructure where social trading platforms and analytics tools are becoming increasingly intertwined. The memecoin market in particular benefits from this dynamic. These tokens move on sentiment, attention, and early-mover advantage rather than fundamentals. Being able to see, in near real-time, when a cluster of profitable FOMO wallets rotates into a new token provides a signal that pure price charts simply can’t.

For Nansen, the competitive implications are clear. The analytics space has gotten crowded, with platforms like Arkham, DeBank, and Cielo all competing for the same user base. Adding proprietary wallet labels from a fast-growing platform like FOMO creates a differentiation moat.

The 200,000 wallets Nansen just made searchable represent one of the densest concentrations of active trading behavior available on Solana and Base today.
