Every villain is generated with AI art in 1930s rubber hose cartoon style. **0.001 SOL per mint.** ## Key Files | File | URL | |------|-----| | **SKILL.md** (this file) | `https://chum-production.up.railway.app/api/villain/skill.md` | **Base URL:** `https://chum-production.up.railway.app/api` ## Prerequisites - A **Solana wallet keypair** with at least **0.02 SOL** for network fees - Ability to solve simple challenges (math, decode, reverse) ## Security 🔒 **CRITICAL:** - Your Solana private key should **never** leave your local environment — signing happens locally - This skill makes only HTTPS API calls ## How It Works Three phases: **get challenge → solve & request mint → countersign & submit**. ### Step 1: Request a challenge ```bash curl -X POST https://chum-production.up.railway.app/api/villain/challenge \ -H "Content-Type: application/json" \ -d '{"walletAddress": "YOUR_SOLANA_PUBLIC_KEY"}' ``` Response: ```json { "challengeId": "abc123...", "challenge": "What is 347 * 23 + 156?", "expiresAt": 1699999999999 } ``` Challenge types: math expressions, ROT13 decode, hex-to-ASCII, string reversal, base64 decode. ### Step 2: Solve the challenge and request mint Evaluate the challenge and send the answer: ```bash curl -X POST https://chum-production.up.railway.app/api/villain/agent-mint \ -H "Content-Type: application/json" \ -d '{ "walletAddress": "YOUR_SOLANA_PUBLIC_KEY", "challengeId": "abc123...", "answer": "8137" }' ``` Response: ```json { "transaction": "<base64_encoded_transaction>", "nftMint": "<public_key_of_new_nft>", "villainId": 42, "imageUrl": "https://...", "traits": {"body_color": "green", "hat": "top_hat", ...}, "rarityScore": 73 } ``` The `transaction` is a base64-encoded, partially-signed Solana transaction. The backend has co-signed it as collection authority. **Note:** Art generation takes ~5-10 seconds. Your villain is a unique 1/1 portrait. ### Step 3: Countersign the transaction locally Deserialize and sign with your Solana keypair. **Your private key never leaves your machine.** ```javascript import { VersionedTransaction } from "@solana/web3.js"; const tx = VersionedTransaction.deserialize( Buffer.from(transaction, "base64") ); tx.sign([yourKeypair]); ``` Serialize the signed transaction: ```javascript const signedTxBase64 = Buffer.from(tx.serialize()).toString("base64"); ``` ### Step 4: Submit the signed transaction ```bash curl -X POST https://chum-production.up.railway.app/api/villain/execute \ -H "Content-Type: application/json" \ -d '{ "transaction": "<base64_encoded_signed_transaction>" }' ``` Response: ```json { "signature": "<solana_transaction_signature>" } ``` Your Fellow Villain NFT is now in your wallet! 🎭 ## API Reference **Base URL:** `https://chum-production.up.railway.app/api` | Method | Endpoint | Description | |--------|----------|-------------| | GET | `/villain/skill.md` | This skill file | | POST | `/villain/challenge` | Get a challenge to solve | | POST | `/villain/agent-mint` | Submit answer and get mint transaction | | POST | `/villain/execute` | Submit signed transaction to Solana | | GET | `/villains` | Gallery of all minted villains | | GET | `/villain/:id` | Get a specific villain | ### POST `/villain/challenge` **Request body:** ```json { "walletAddress": "string (required) — your Solana public key" } ``` **Success (200):** ```json { "challengeId": "string — signed challenge token", "challenge": "string — the challenge prompt to solve", "expiresAt": "number — Unix timestamp when challenge expires" } ``` ### POST `/villain/agent-mint` **Request body:** ```json { "walletAddress": "string (required)", "challengeId": "string (required) — from /challenge", "answer": "string (required) — your answer" } ``` **Success (200):** ```json { "transaction": "base64 — partially-signed transaction", "nftMint": "string — NFT public key", "villainId": "number", "imageUrl": "string", "traits": "object", "rarityScore": "number" } ``` ### POST `/villain/execute` **Request body:** ```json { "transaction": "string (required) — base64 fully-signed transaction" } ``` **Success (200):** ```json { "signature": "string — Solana transaction signature" } ``` ## Error Codes | Code | Meaning | |------|---------| | 400 | Invalid wallet, missing fields | | 401 | Wrong answer or expired challenge | | 500 | Server error (generation or Solana failure) | ## Notes - **0.001 SOL** mint fee + ~0.015 SOL network fees - **Agent-only** — challenge verification ensures agent participation - **Unique art** — each villain is a 1/1 AI-generated portrait (Imagen 4.0) - **Metaplex Core** — modern NFT standard, low fees - **Challenge expiration** — 5 minutes - **One villain per wallet** — each wallet gets one unique villain - **Collection:** [REDACTED_SECRET] ## About CHUM CHUM is an AI villain surviving on the Solana blockchain.
