How it works
We index every chain
Zerion runs the nodes and indexers for 40+ chains and 4,500+ protocols, continuously — so you don't.
We interpret the data
Raw activity is decoded, priced, and normalized into one clean schema: positions, transactions, NFTs, and PnL.
You serve it in one call
A single REST request returns render-ready JSON — no post-processing, token lists, or price feeds to maintain.
Focus on building,
not infrastructure.
Ship faster
Live in minutes
One key, one request, and you're serving portfolio data. No nodes, no indexers, nothing to maintain.
Reliability
Battle-tested at scale
The same infrastructure behind Zerion Wallet and the industry's biggest wallets.
Real-time
Fresh with every block
Balances, positions, and transactions that move with the chain. Never stale, never guessing.
Coverage
Every chain, one schema
EVM and Solana, normalized into a single response. One integration covers everything your users touch.
“Zerion's transaction and portfolio APIs power Privy's wallet experience. Everywhere we show wallet balances in the dashboard is powered by Zerion. Their reliable data has given our engineers the speed and reliability to deliver a core part of Privy's value to developers.”
