Wallets
Build modern crypto wallets with comprehensive asset tracking and real-time updates
Modern crypto wallets are no longer just key signers—they’re real-time asset dashboards. Users expect to see their balances, NFTs, and protocol positions across multiple chains, all at once, and all up to date. Anything slower than real time, or less than complete, breaks trust and drives users away.
What Wallet Builders Care About
Building a modern wallet requires more than just querying balances. You need:
Complete asset picture
A complete picture of all wallet assets (tokens, NFTs, LPs, staked positions)
Cross-chain coverage
Cross-chain coverage with consistent formats
Real-time updates
Real-time updates without polling
Smooth experience
Fast and stable UX across mobile and web
Simple integration
Simple integration and low backend maintenance
How ChainStream Helps
ChainStream removes the pain of managing blockchain integrations and building custom data pipelines. You can power a full wallet interface—tokens, NFTs, DeFi—all from a single API call, updated in real time.
Unified asset view
Show full token, NFT, and DeFi holdings for any address, across 25+ chains, with a single query.
Real-time sync
Push-based architecture means your UI updates the moment balances or ownership change.
Event-level granularity
Go beyond “balance” and track how and why it changed—detect transfers, new deposits, protocol interactions, or unusual behavior.
No indexing required
Everything is pre-normalized and query-ready. No need to decode logs, track tokens manually, or parse NFT metadata yourself.
Built for wallets, not explorers
Our asset engine is optimized for consumer wallets—not block explorers. That means better formatting, faster loading, and structured filters that fit into your product’s UI.
APIs to Build With
Use Cases That Matter
Mobile or Browser-Based Wallets
Power multi-chain portfolios in your wallet UI with accurate token/NFT balances and real-time updates.
Hardware or Smart Contract Wallet Interfaces
Show activity history, real-time gasless claim status, or staked position values across protocols.
NFT Wallets & Collectibles Apps
Fetch image, rarity, collection info, and real-time ownership status across Solana, Ethereum, and more.
Token Watchlists & Activity Feeds
Let users track token inflows, suspicious approvals, or NFT floor price changes tied to their wallet.
Wallet Notifications
Trigger notifications for wallet events: “You just received X token,” “Your NFT was sold,” or “This address is under risk.”
What You’ll Get
Faster product launches
Skip writing custom indexers or syncing RPC endpoints per chain.
Unified asset logic
No more maintaining token lists, NFT formatters, or DeFi position decoders—ChainStream handles the complexity.
Better user experience
Your app feels instant and reliable, with no outdated balances or missed NFT events.
Lower cost, higher performance
One API call replaces dozens. Real-time streams reduce polling, saving bandwidth and compute.
