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! 🎭

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: EK9CvmCfP7ZmRWAfYxEpSM8267ozXD8SYzwSafkcm8M7
