Stablecoins move globally, but their data remains fragmented by chain.
Zerion gives products one clear view of every balance, transfer, and position.
Product mapping
The endpoints a stablecoin product is built on — and what each one returns.
/fungiblesFungibles
Token metadata, logos, live and historical prices.
/positionsPositions
Idle versus earning stablecoin holdings, normalized.
/transactionsTransactions
Transfers decoded and labeled across every chain.
/portfolioPortfolio
Net worth and allocation by chain and position type, one call.
/chainsChains
40+ chains, EVM and Solana normalized.
/subscriptionsAlerts
Real-time push on new transactions and balance changes.
/pnlPnL
Realized and unrealized gains, cost basis, net invested (FIFO).
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.
“The Zerion team is deeply technical and great to work with. They ship reliable, well-documented infrastructure and move fast when it matters, which is exactly what you want from a partner you're building on top of.”
