# Overview

> Manage ENS avatar and header images with SIWE authentication.

`@thenamespace/avatar` uploads, updates, and deletes avatar and header images for ENS subnames through the Namespace Metadata Service. Authentication uses SIWE v4, and the SDK accepts a Viem `WalletClient`, an Ethers `Wallet` or `Signer`, or any object matching the `WalletProvider` interface directly, no adapter required.
