One integration. Full crypto context. Built for the products being built in 2026.
Aggregated prices from 300+ exchanges. Volume-weighted, timestamped, and normalized to a single schema. No more bad data from single-exchange feeds.
Query any wallet across any chain. Balances, token holdings, transaction history — all in one response, one key, one schema.
Detect and decode DeFi positions across 10,000+ protocols. Staked assets, LP positions, lending collateral — surfaced in one call.
Ethereum, Solana, Base, Arbitrum, Polygon, Hyperliquid, and 115+ more. One endpoint to rule them all — add new chains without touching your code.
Structured JSON responses designed for LLM consumption. MCP server available. No parsing required — just call and use.
Transparent pricing that doesn't require an enterprise sales call. Free tier for prototyping. Paid tiers that scale with you, not against you.
Most crypto APIs were built for one thing — and then bolted on the others. ChainDeck was built to be unified from day one.
One response format across every endpoint. No vendor-specific quirks to work around.
We aggregate and normalize at the API layer — you receive clean data, not raw chaos.
TypeScript SDK, comprehensive docs, and a free tier that actually lets you build something real.
No sales call required. No opaque enterprise tiers. Just pricing that makes sense for what you're building.
