@exodus/fee-data-monitors

This Exodus SDK feature provides feeData, which are inputs for fee calculations performed by the client when building a transaction for user approval. The shape of feeData varies per asset, e.g. it might contain feePerKB for bitcoin and baseFeePerGas for ethereum.

The feeData returned by this monitor MAY be assembled from several parts:

Static fee related data defined in asset libraries
Fee related data fetched from remote-config
Fee related data fetched by the asset specific fee data monitor

Install

npm i @exodus/fee-data-monitors

pnpm add @exodus/fee-data-monitors

yarn add @exodus/fee-data-monitors

bun add @exodus/fee-data-monitors

Usage

This feature is designed to be used together with @exodus/headless. See using the sdk.

Play with it

Open the playground https://exodus-hydra.pages.dev/features/fee-data-monitors
Run await exodus.fees.getFeeData({ assetName: 'bitcoin' }) in the Dev Tools Console.
Run selectors.feeData.createData('bitcoin')(store.getState()) in the Dev Tools Console.

API Side

See using the sdk for more details on how features plug into the SDK and the API interface in the type declaration .

const bitcoinFeeData = await exodus.fees.getFeeData({ assetName: 'bitcoin' });

If you’re building a feature that requires the wallet’s addresses, add a dependency on the feeDataAtom atom, which stores data in the shape of { [assetName]: feeData }

UI Side

See using the sdk for more details on basic UI-side setup.

import { useSelector } from 'react-redux';
import selectors from '~/ui/flux/selectors';
 
const MyComponent = () => {
  // TODO: API and selector namespaces should match
  const feeData = useSelector(selectors.feeData.createData('bitcoin'));
  return <Text>{JSON.stringify(feeData)}</Text>;
};
