Comments in Sage Protocol create explicit, threaded discussions as blockchain-native posts directly linked to parent posts. Threading ensures hierarchical, readable interactions.

​
Creating Comments

To comment on a post, you must have the original post’s ID and the author’s shared user ID. React Hook Example for Creating Comments: 
import { usePost } from '@sageprotocol/sdk/react';
import { useWallet } from '@suiet/wallet-kit';

function CreateComment({ parentPostId, authorSharedUserId, ownedUserId }) {
  const { commentOnPost } = usePost();
  const { account, signAndExecuteTransaction } = useWallet();

  async function handleCreateComment() {
    const result = await commentOnPost({
      amounts: [0, 0],                                // Required protocol fees
      appId: 'your-app-id',                           // Required application ID
      network: 'testnet',                             // 'testnet' or 'mainnet'
      authorSharedUserId,                             // Original post author's shared user ID
      parentPostId,                                   // ID of the parent post
      title: 'Great insights!',                       // Comment title in markdown
      description: 'Adding my perspective',           // Comment summary in markdown
      data: 'I completely agree with your points, especially regarding scalability...', // Main markdown

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 createComment(parentPostId, authorSharedUserId, ownedUserId, walletAddress) {
  const result = await sageClient.commentOnPost({
    amounts: [0, 0],                                // Required protocol fees
    authorSharedUserId,                             // Original post author's shared user ID
    parentPostId,                                   // ID of the parent post
    title: 'Great insights!',                       // Comment title in markdown
    description: 'Adding my perspective',           // Comment summary in markdown
    data: 'I completely agree with your points, especially regarding scalability...', // Main markdown content
    ownedUserId,                                    // Commenter's owned user ID
    self: walletAddress                             // Commenter's wallet address
  });

  if (result.ok) {
    await signAndExecuteTransaction({ transaction: result.transaction });
    console.log("Comment created successfully!");
  } else {
    console.error("Error creating comment:", result.err);
  }
}

createComment('parent-post-id', 'author-shared-user-id', 'your-owned-user-id', walletAddress);
