Channel owners can update channel information including descriptions, avatars, banners, and the casing of channel names. Updates require explicitly providing all fields to avoid unintended overwrites; unchanged fields should retain existing values. React Hook Example for Updating Channels: 
import { useChannel } from '@sageprotocol/sdk/react';
import { useWallet } from '@suiet/wallet-kit';

function UpdateChannel({ channel }) {
  const { update } = useChannel();
  const { account, signAndExecuteTransaction } = useWallet();

  async function handleUpdate() {
    const result = await update({
      amounts: [0, 0],                                // Required protocol fees
      avatar: channel.avatar,                         // Existing or updated blob ID
      banner: channel.banner,                         // Existing or updated blob ID
      channelId: channel.id,                          // Channel ID
      channelName: channel.name,                      // Casing updates only (e.g., 'crypto-art' → 'CRYPTO-ART')
      description: '**Updated community guidelines and information**', // Markdown-supported description
      self: account.address                           // Channel owner's wallet address
    });

    if (result.ok) {
      await signAndExecuteTransaction({ transaction: result.transaction });
      console.log("Channel updated successfully!");
    } else {
      console.error("Error updating channel:", result.err);
    }
  }

  return <button onClick={handleUpdate}>Update Channel</button>;
}

export default UpdateChannel;

Important Notes:

  • Complete Replacement: Updates are full replacements; explicitly provide all fields, using existing values for unchanged fieldsdocssage_sdk.
  • Name Casing Restrictions: Channel names can only be modified by changing letter casing, not by introducing new characters or wordssage_sdk.
  • Transaction Signing: All updates require explicit signing and execution via the owner’s walletdocs.
