Symmio Frontier — the SDK surface for builders on HyperEVM
Home

SYMM Frontier

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

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, then walk through Getting Started.

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 SYMM Frontier package; bring your own copy.
