Users can post directly onto other users’ profiles for interactions like endorsements, community appreciation, or personal engagement. Posts support rich markdown content. Posting to User Profiles Using React Integration: 
import { usePost } from '@sageprotocol/sdk/react';
import { useWallet } from '@suiet/wallet-kit';

function PostToUser({ targetSharedUserId, ownedUserId }) {
  const { postToUser } = usePost();
  const { account, signAndExecuteTransaction } = useWallet();

  async function handlePostToUser() {
    const result = await postToUser({
      amounts: [0, 0],                                  // Required protocol fee amounts
      appId: 'your-app-id',                             // Required application ID
      network: 'testnet',                               // 'testnet' or 'mainnet'
      sharedUserId: targetSharedUserId,                 // Target user's shared user object ID
      ownedUserId,                                      // Poster's owned user object ID
      self: account.address,                            // Wallet address of the poster
      title: '🌟 Professional Recommendation',           // Post headline/title (markdown supported)
      description: 'Endorsement for exceptional work',  // Brief summary (markdown supported)
      data: 'Your contributions to the project were outstanding!' // Main markdown content
    });

    if (result.ok) {
      await signAndExecuteTransaction({ transaction: result.transaction });
      console.log("Posted to user profile successfully!");
    } else {
      console.error("Error posting to user profile:", result.err);
    }
  }

  return <button onClick={handlePostToUser}>Post to User</button>;
}

export default PostToUser;

Important Notes:

  • Protocol Fees: Explicitly set to [0, 0] by default.
  • appId and network: Explicitly required for application context and blockchain network selection.
  • Markdown Content: Supported in title, description, and data fields.
  • Transaction Execution: Transactions must always be signed and executed explicitly via the user’s connected walletdocssage_sdksage_sdk.
