Components

Davatar

The <Davatar /> component takes an Ethereum address, the desired avatar size, and an optional Web3 provider and displays the avatar attached to the ENS reverse record assigned to the address, if it exists. Otherwise, it displays the Jazzicon for the address.

// ...
  return (
    <Davatar
      size={24}
      address='0x00000000000000000000000'
      provider={provider} // optional
      graphApiKey={apiKey} // optional
      generatedAvatarType='jazzicon' // optional, 'jazzicon' or 'blockies'
    />
  );
// ...

Image

If you know the avatar URI (available URI types), you can use the <Image /> component which takes an image URI, avatar size, and an optional Ethereum address, and displays the image from the URI. If the URI is undefined or null, and the address is specified, it displays a Jazzicon. It supports the following URI types:

• HTTP(S)
• IPFS/IPNS
• Arweave (ar://), with support for Origin "mutability" tags
• Data URLs

// ...
  return (
    <Image
      size={24}
      address='0x00000000000000000000000'
      uri='ar://0dbf9uwer8gw7efrg9bwe08r9v90ew8'
      graphApiKey={apiKey} // optional
      generatedAvatarType='jazzicon' // optional, 'jazzicon' or 'blockies'
    />
  );
// ...

Caching

In order to prevent unnecessary and frequent re-querying of the blockchain for avatar metadata, the library caches fetched avatar URIs for 24 hours. This cache is maintained in local storage and looks like this:

key: davatar/cache
value: [address]{ avatar url, expiredAt: expiry datetime }
