Fomo

Fomo uses Allium Developer APIs to power cross-chain trading across Hyperliquid and Monad. By replacing their in-house data engineering stack, Allium helped Fomo's team focus on shipping product instead of maintaining their own RPC infrastructure.

MetaMask

MetaMask uses Allium APIs to power real-time balance calculations and transaction data across their wallet infrastructure.

"After migrating to Allium's DB to help find active EVM addresses, we're seeing a 30%-45% drop in P50/P99 latency and no more sharp latency spikes. In addition, we will no longer be subject to outages with other providers."
