Social Engines

Social interactions are handled by single-purpose, ownerless contracts. All of them are payable (they carry KAIA) and reference content by its keccak256 digest.

#TransferEngine

function transfer(address recipient) payable;

• A fixed fee of 0.01 KAIA (100% to the SharePool). The remainder goes to the recipient.
• value = amount to send + the 0.01 KAIA fee.

#How is postIdHash produced?

Digest the offchain post id (a UUID for example) with keccak256:

import {keccak256, toBytes} from "viem";
const postIdHash = keccak256(toBytes(postId));

Always use the same string for the same post so the digest stays consistent.
