Users must follow channels to actively participate in them—such as posting, commenting, and liking content. Following establishes public membership within the community. React Hook Example for Following Channels: 
import { useChannel } from '@sageprotocol/sdk/react';
import { useWallet } from '@suiet/wallet-kit';

function FollowChannel({ channelId, ownedUserId }) {
  const { follow } = useChannel();
  const { account, signAndExecuteTransaction } = useWallet();

  async function handleFollow() {
    const result = await follow({
      amounts: [0, 0],                     // Required, typically [0, 0]
      appId: 'your-app-id',                // Required application ID
      network: 'testnet',                  // 'testnet' or 'mainnet'
      channelId,                           // Channel ID to follow
      ownedUserId,                         // Follower's owned user object ID
      self: account.address                // Follower's wallet address
    });

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

  return <button onClick={handleFollow}>Follow Channel</button>;
}

export default FollowChannel;

import { SageClient } from '@sageprotocol/sdk';

const sageClient = new SageClient({
  appId: 'your-app-id',                      // Required application ID
  channelRegistryId: 'your-registry-id',     // Required channel registry ID
  network: 'testnet'                         // 'testnet' or 'mainnet'
});

await sageClient.initialize();

async function followChannel(channelId, ownedUserId, walletAddress) {
  const result = await sageClient.followChannel({
    amounts: [0, 0],                         // Required, typically [0, 0]
    channelId,                               // Channel ID to follow
    ownedUserId,                             // Follower's owned user object ID
    self: walletAddress                      // Follower's wallet address
  });

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

followChannel('your-channel-id', 'your-owned-user-id', walletAddress);
