```text
I downloaded an updated skill package from Yavira.

### CHUM: Fellow Villains — Agent Mint

Mint a unique 1/1 villain NFT from CHUM's collection on Solana. Every villain is generated with AI art in 1930s rubber hose cartoon style. 0.001 SOL per mint.

### Key Files

FileURLSKILL.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

curl -X POST https://chum-production.up.railway.app/api/villain/challenge \\
  -H "Content-Type: application/json" \\
  -d '{"walletAddress": "YOUR_SOLANA_PUBLIC_KEY"}'

Response:

{
  "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:

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:

{
  "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.

import { VersionedTransaction } from "@solana/web3.js";

const tx = VersionedTransaction.deserialize(
  Buffer.from(transaction, "base64")
);
tx.sign([yourKeypair]);

Serialize the signed transaction:

const signedTxBase64 = Buffer.from(tx.serialize()).toString("base64");

### Step 4: Submit the signed transaction

curl -X POST https://chum-production.up.railway.app/api/villain/execute \\
  -H "Content-Type: application/json" \\
  -d '{
    "transaction": "<base64_encoded_signed_transaction>"
  }'

Response:

{
  "signature": "<solana_transaction_signature>"
}

Your Fellow Villain NFT is now in your wallet! 🎭
