@dhedge/trading-widget v3.10.6

dHEDGE Trading Widget API Docs

Get started

Requirements:

Widget library has some vital peerDependencies as a core tool stack. Make sure having all those dependencies installed in app before starting the integration:

"@tanstack/react-query": "^5.28.4",
"react": ">=18.2.0",
"viem": "^2.8.14",
"wagmi": "^2.5.11"

1. Installation:

npm i @dhedge/trading-widget

2. Providers hierarchy

import { WagmiProvider } from 'wagmi'
import { TradingPanelProvider, TradingWidget } from '@dhedge/trading-widget'

• Setup Wagmi Provider on top level or use existing one in your app
• Setup TradingPanelProvider

  Providing a getSwapData callback is mandatory for depositing with off-chain swaps.

• Setup TradingWidget

3. Minimum required config

See bare minimum setup example: packages/trading-widget/src/examples/simple-example.tsx

4. Styling

import '@dhedge/trading-widget/style.css'

Initially widget takes full parent width

See TradingWidget -> theme config to manage customization
