Why engineering teams choose Allium
vs. building with rpc providers
RPS providers give you raw blockchain data, you still need to decode it, handle reorgs and build pipelines before its usable
time to production
what you get
reorg handling
total monthly cost
maintenance
vs API providers
API providers offer convenient endpoints but limit you to their data model — you can't vet the underlying data or run custom queries.
Data access
Customization
Data verification
Scale
vs Subgraphs
Subgraphs give you flexible graph queries but create expensive scaling costs and require specialized expertise to transform and analyze data.
Data format

Historical data
Scaling costs
RPCs require months of engineering work. APIs lock you into their endpoints. Subgraphs need specialized expertise. Allium delivers production-ready, verified data that every team can use from day one.
Launch in days, not months
Real-time APIs and streams with decoded data across chains. Build applications without managing nodes or indexers.
Scale without owning infrastructure
Handle millions of requests and events with predictable pricing. We manage the infrastructure and reorgs.
Verify every data point
Full methodology documentation and SQL access to underlying data. Check our work yourself — no black boxes.
Powering the highest performance apps
Phantom uses Allium Developer APIs to power wallet balances and transaction histories for millions of users. During Jupiter's 2024 airdrop, Allium handled 90,000 requests per second with zero downtime.
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 uses Allium APIs to power real-time balance calculations and transaction data across their wallet infrastructure.
Built on Allium's dedicated Hyperliquid node, our realtime Hyperliquid dashboard surfaces trades, validator activity, and protocol metrics as they happen onchain.

Uptime SLA
"After switching to Allium 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 from other providers."
