SYMMIO Trading-SDK

The SDK and reference apps for SYMMIO. Build trading UIs against SYMMIO without re-implementing contract calls, chain plumbing, or wallet UX from scratch.

These docs cover every detail of the SDK. If you want to build a product on top of it, first read the Build a Perps DEX guide to get the basic context of the whole flow, then dive into the individual APIs below.

What’s in this docs site

Pick a library from the top nav:

  • Core — @symmio/trading-core: framework-agnostic SDK. Contract calls, ABI fragments, the per-chain address registry, typed errors.
  • React — @symmio/trading-react: React adapter. Hooks, providers, and react-query-shaped wrappers on top of core.
  • Utils — @symmio/utils: framework-agnostic helpers — amount formatting, Decimal.js math, display formatters, address helpers.

If this is your first time here, start with Introduction to pick a layer, then walk through that library’s Getting Started — Core, React, Utils, or Session Key.

Install

# everything you need to ship a React UI
pnpm add @symmio/trading-react @symmio/utils viem wagmi @tanstack/react-query
 
# or just the framework-agnostic SDK (for Node scripts, Vue, Solid)
pnpm add @symmio/trading-core viem

viem is a peer dependency of every SYMMIO Trading-SDK package; bring your own copy.
