New self-service API portal provides instant access to Ethereum and Solana wallet data—the same infrastructure powering Uniswap, Base App, Kraken, Infinex
Zerion today launched a self-service developer portal for its wallet data API, opening enterprise-grade infrastructure to builders worldwide. Previously available only through custom agreements, developers can now create API keys and start building in minutes.
The API provides comprehensive Ethereum and Solana wallet data, including token portfolios, DeFi positions, NFTs, and profit/loss analytics, eliminating the need for teams to build their own indexers or data pipelines.
“We’ve spent years building wallet data infrastructure for Zerion Wallet and some of the most demanding teams in crypto. Any developer can now tap into that same infrastructure in a few clicks. This is about lowering the barrier to building incredible crypto products,” said Abishek Dharshan, API Product Lead at Zerion.
Zerion API already powers wallet experiences for Uniswap, Infinex, OpenSea, Privy, Coinbase, and other leading crypto products serving millions of users. The API offers unified data models across Ethereum and Solana, production-grade accuracy and reliability, and single integration for multi-chain coverage.
The developer portal is live today globally. Zerion offers a generous free tier for prototyping, with paid plans scaling to millions of monthly requests for production workloads.
What Developers Get With Zerion API
The new Zerion API developer portal enables developers to create API keys to get instant access to:
- Token balances and portfolio breakdowns
- DeFi positions across protocols
- Realized and unrealized PnL for any address and token
- NFT holdings and collections
