Introduction
Wallet-ready APIs for balances, gas, and cross-chain swap quotes — one integration instead of dozens.
The ChainKit API returns normalized wallet data across many chains through a single interface. It handles token discovery, fresh on-chain balances, pricing, and spam/dust filtering for you. All endpoints are versioned under /v1, return JSON, and represent amounts as strings to preserve precision.
