@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​

yarn add @exodus/fee-data-monitors

Usage​

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

Play with it​

  1. Open the playground https://exodus-hydra.pages.dev/features/fee-data-monitors
  2. Run await exodus.fees.getFeeData({ assetName: 'bitcoin' }) in the Dev Tools Console.
  3. 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>
}
