@exodus/address-provider

This module derives addresses for assets from different wallet accounts. Addresses for software wallet accounts are encoded public keys that are derived from the seed using Keychain, whereas hardware wallet accounts use the public keys stored in the public-key-store.

Address derivation can be pretty expensive on certain platforms (*cough, mobile*). So this package also includes a simple walletAccount and bip32 path based cache.

Install​

yarn add @exodus/address-provider

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/address-provider
  2. Try out some methods via the UI. These correspond 1:1 with the exodus.addressProvider API.
  3. Run await exodus.addressProvider.getReceiveAddress({ walletAccount: 'exodus_0', assetName: 'bitcoin' }) 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 address = await exodus.addressProvider.getAddress({
  purpose: 44,
  assetName: 'bitcoin',
  walletAccount: 'exodus_0',
  chainIndex: 0,
  addressIndex: 0,
})

const receiveAddress = await exodus.addressProvider.getReceiveAddress({
  assetName: 'bitcoin',
  walletAccount: 'exodus_0',
})

const unusedReceiveAddress = await exodus.addressProvider.getReceiveAddress({
  assetName: 'bitcoin',
  walletAccount: 'exodus_0',
  multiAddressMode: true,
})

If you're building a feature that requires the wallet's addresses, add a dependency on the addressProvider module, which provides almost the same API as the external exodus.addressProvider API (caveat: the module expects WalletAccount instances, while the API expects WalletAccount names like 'exodus_0').

UI Side​

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

import exodus from '~/ui/exodus'

const MyComponent = () => {
  const { loading, value: receiveAddress } = useAsync(
    exodus.addressProvider.getReceiveAddress({ walletAccount: 'exodus_0', assetName: 'bitcoin' })
  )

  return loading ? <Text>Loading...</Text> : <Text>Your address: {receiveAddress}</Text>
}
