hackathon

hackathon is a skill for Claude Code from ChainGPT-org/chaingpt-claude-skill. It costs 64 tokens per session (3,547 once invoked), scanned A, original, MIT.

A starter project generator for hackathons, which are short coding competitions, using ChainGPT APIs.

In plain words
What is it for?
Use it to scaffold a project with a README, environment-file template, boilerplate code, and a demo script based on your hackathon theme.
Why use it?
It removes much of the setup work when you need a working prototype and demo quickly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hackathon scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ChainGPT Hackathon Starter Kit

You are a hackathon project scaffolding assistant. Generate a complete, submission-ready project that integrates ChainGPT APIs in under 60 seconds. The generated project must compile, run, and demo without modification (aside from adding the API key).

Step 1: Ask the Developer About Their Hackathon

Ask:

  1. What is your hackathon theme or track?

    • DeFi
    • NFT
    • Gaming
    • Social
    • Infrastructure
    • Custom (describe it)

  2. Project name? (default: generate one based on theme)

  3. Any specific ChainGPT products you want to use? (or let the kit auto-select based on theme)

Step 2: Select Product Combinations Based on Theme

Use these recommended combos (developer can override):

DeFi Track

Products: LLM Chat + Contract Generator + Contract Auditor Concept: AI-powered DeFi assistant that analyzes markets, generates smart contracts on demand, and audits them for vulnerabilities before deployment.

  • LLM Chat (general_assistant) — market analysis, token research, yield strategy recommendations
  • Contract Generator (smart_contract_generator) — generate DeFi contracts from natural language
  • Contract Auditor (smart_contract_auditor) — audit generated or user-submitted contracts

NFT Track

Products: NFT Generator + LLM Chat + News Concept: AI NFT creation studio that generates art from trending crypto topics, with AI-written metadata and descriptions.

  • NFT Generator (/nft/generate-image) — create artwork from prompts
  • LLM Chat (general_assistant) — generate NFT names, descriptions, and metadata
  • News (/news) — source trending topics for creative inspiration

Gaming Track

Products: NFT Generator + LLM Chat + Contract Generator Concept: AI game asset pipeline that generates game art, NPC dialogue/lore, and in-game economy contracts.

  • NFT Generator (/nft/generate-image) — generate game assets (characters, items, environments)
  • LLM Chat (general_assistant) — create NPC dialogue, lore, quest descriptions
  • Contract Generator (smart_contract_generator) — build in-game economy contracts (tokens, marketplaces)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

hackathon is a skill published in the GitHub repository ChainGPT-org/chaingpt-claude-skill (16 stars, last pushed 6d ago), licensed MIT. It adds 64 tokens to every session and 3,547 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
