FAQ
Use **/positions** to fetch a user’s normalized holdings across DeFi protocols and NFTs. You’ll get resolved positions (e.g., lending, staking, LPs) without maintaining your own protocol integrations.
Yes. Combine **/positions** with **/transactions** to show portfolio plus onchain activity. Add token metadata and prices to label assets and compute valuations.
No. Zerion handles node access, indexing, and caching behind read-only endpoints. You focus on product and UI instead of infrastructure.
Yes. The unified object model means your Scroll integration closely mirrors Ethereum and other L2s, reducing multi-chain complexity.
Create a key, pick a known address, call **/positions** to render holdings, then add **/transactions** and token metadata for a complete wallet view.
