San Francisco-based wallet infrastructure company Zerion has launched a self-service developer portal for its enterprise-grade wallet data API, making the service available to all developers worldwide as of January 22, 2026. Previously accessible only through custom agreements, the API now allows developers to create API keys and begin building applications within minutes.
The Zerion API provides comprehensive wallet data for both the Ethereum and Solana blockchains, including detailed token portfolios, DeFi positions across various protocols, NFT holdings and collections, and realized/unrealized profit and loss analytics for any address. This infrastructure eliminates the need for development teams to build their own complex indexers or data pipelines from scratch.
"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.
The API already powers wallet experiences for major crypto platforms including Uniswap, Infinex, OpenSea, Privy, Coinbase, Base App, and Kraken, serving millions of users. Key features include unified data models across Ethereum and Solana, production-grade accuracy and reliability, and a single integration point for multi-chain coverage.
The new developer portal offers a generous free tier for prototyping, with paid plans that scale to support millions of monthly requests for production workloads. The API provides instant access to token balances and portfolio breakdowns, DeFi positions across protocols, PnL analytics for any address and token, NFT holdings and collections, along with self-service billing and usage management.
Zerion supports developers building wallet-based applications and users managing assets across Ethereum, Solana, and 50+ EVM-compatible networks. The company is known for its intuitive user experience and reliable data infrastructure that powers its own non-custodial crypto wallet alongside these developer APIs.
