Preventing AI Image Insurance Fraud

What it does

From the project README:

Know a claim photo is real before you pay it. We don't try to spot fake insurance-claim photos. We prove the real ones, on a shared Solana record no single insurer controls.

Dapp: devnet deploy pending

⏳ Devnet deploy pending — goes live when the devnet wallet is topped up. This fork's own dapp is not deployed yet, so there is no program address or transaction to show. It is queued in dapp-queue.txt; once devnet SOL is available it is deployed, exercised with real devnet transactions, and this section switches to the live dapp at /dapps/fraudbusters/. Until then, the lesson and step-by-step guide below are complete, and you can run it locally with the commands below.

Key code, explained

Excerpts chosen automatically where the code uses the most Solana concepts, pinned to the fork's commit.

EmuCS/FraudBusters · src/solana.js L1–24 @ 600c70b · MIT · original

import fs from 'node:fs';import path from 'node:path';import {  Connection,  Keypair,  PublicKey,  Transaction,  TransactionInstruction,  sendAndConfirmTransaction,} from '@solana/web3.js';import {  getMint,  getAssociatedTokenAddressSync,  createAssociatedTokenAccountIdempotentInstruction,  createTransferCheckedInstruction,} from '@solana/spl-token';import { RPC_URL, CLUSTER, KEYS_DIR } from './config.js'; export const MEMO_PROGRAM_ID = new PublicKey('MemoSq4gqABAXKb96qnH8TysNcWxMyWCqXgDLGmfcHr');export const connection = new Connection(RPC_URL, 'confirmed'); export function keyPath(name) {  return path.join(KEYS_DIR, `${name}.json`);}

Line 9 sendAndConfirmTransaction,: Submits the signed transaction to the cluster.
Line 15 createTransferCheckedInstruction,: A checked token transfer, which also verifies the mint and decimals.

How to run, build and test

These commands come from the repo's own manifests (package.json scripts, Anchor.toml, Cargo, go.mod, Makefile). Check the README for prerequisites and environment variables.
