AutoBounty

Automated GitHub bounty verification using decentralized AI consensus.

GenLayer validators evaluate PRs against issues. Avalanche handles escrow. No human reviewers. Minutes, not weeks.

How it works

GitHub bounty platforms move $100M+/year in developer rewards, but verification is 100% manual. A maintainer has to review every PR, compare it against the issue requirements, and approve the payout. This takes 3-15 days. Small bounties ($50-200) often never get reviewed at all.

AutoBounty replaces the human reviewer with GenLayer's decentralized AI consensus. When a contributor submits a PR, five independent validators — each running a different LLM (GPT, Claude, Gemini, Llama) — scrape the GitHub API, read the issue and the PR, and independently evaluate whether the work meets the requirements.

GenLayer is the only blockchain that can read arbitrary web pages on-chain, reason about code quality in natural language, and achieve multi-model consensus on subjective evaluations. A single LLM is gameable. Five independent models are not.

Architecture

Component	Chain	Description
BountyEscrow.sol	Avalanche Fuji	Solidity contract. Locks mUSDC in escrow, releases payment based on verdict.
MockUSDC.sol	Avalanche Fuji	Freely mintable ERC-20 (6 decimals) for testnet bounties.
BountyJudge.py	GenLayer Bradbury	Intelligent Contract. Fetches GitHub API data, evaluates PR via Optimistic Democracy consensus (Equivalence Principle Pattern 4: prompt_non_comparative).
relayer/index.js	Off-chain	Bridges events between Avalanche and GenLayer. Submits solutions, triggers evaluation, resolves bounties.

Setup

Prerequisites

• Docker 26+
• Node.js 18+
• Foundry (curl -L https://foundry.paradigm.xyz | bash && foundryup)
• API key: OpenAI or Anthropic (for GenLayer Studio validators)

GenLayer

npm install -g genlayer
genlayer init                        # select your LLM provider
genlayer up                          # Studio runs at localhost:8080 (local dev)

Deploy to Testnet Bradbury:

genlayer network testnet-bradbury    # switch to public testnet
genlayer deploy contracts/genlayer/BountyJudge.py

Consensus model: GenLayer uses Optimistic Democracy by default. When BountyJudge calls prompt_non_comparative (Equivalence Principle Pattern 4), the leader node evaluates the PR, then validators independently verify whether the verdict is reasonable. If a validator disagrees, an appeal round kicks in automatically. No extra code needed.

Avalanche (Solidity)

cd contracts/solidity
forge install
forge build
forge test

Deploy to Fuji:

# Deploy MockUSDC first
forge create --rpc-url https://api.avax-test.network/ext/bc/C/rpc \
  --private-key $PK \
  src/MockUSDC.sol:MockUSDC

# Deploy BountyEscrow with relayer address + mUSDC address
forge create --rpc-url https://api.avax-test.network/ext/bc/C/rpc \
  --private-key $PK \
  src/BountyEscrow.sol:BountyEscrow \
  --constructor-args $RELAYER_ADDRESS $MUSDC_ADDRESS

Relayer

cd relayer
npm install
cp .env.example .env   # edit with your contract addresses and keys
node index.js
