High-level overview

• On-chain: contracts/ holds the escrow + authorization logic.
• Off-chain: apps/api/ indexes contract events + provides GitHub-based authorization endpoints; apps/web/ is the human UI.
• Automation: the API can sync GitHub labels/comments when it sees on-chain events (when configured).

Tech stack constraints

• Monorepo: pnpm workspace (keep pnpm-lock.yaml updated). Don’t use npm/yarn.
• Contracts: Foundry (forge/cast/anvil), Solidity ^0.8.24.
• API: Node + TypeScript (ESM) + Fastify + Prisma + viem (keep .js import specifiers in TS).
• Web: Next.js + React + Tailwind.

Setup

• Install deps: pnpm install

Separate DB per branch (recommended)

The API uses a local SQLite DB for indexing + metadata. If you switch git branches and run migrations against the same DB file, you can “pollute” your main-branch DB schema/data.

To isolate, set a different DB file per branch, e.g.:

• main: DATABASE_URL=file:./prisma/dev-main.db

Local dev (Anvil)

1. Start a local chain:
   • pnpm contracts:anvil
2. Set env:
   • copy .env.example -> .env
   • set BACKEND_SIGNER_PRIVATE_KEY (used by the API to sign payout authorizations)
     • important: this must match the payoutAuthorizer baked into the contract at deploy time (the deploy script derives it from BACKEND_SIGNER_PRIVATE_KEY)
   • set GitHub OAuth env vars (used by “Login with GitHub” in the web UI):
     • WEB_ORIGIN=http://localhost:3000
     • GITHUB_OAUTH_CLIENT_ID=...
     • GITHUB_OAUTH_CLIENT_SECRET=...
     • GITHUB_OAUTH_CALLBACK_URL=http://localhost:8787/auth/github/callback
3. Deploy the contract (in another terminal):
   • pnpm contracts:deploy:local
   • put the deployed CONTRACT_ADDRESS into .env
4. Set web env:
   • copy apps/web/.env.local.example -> apps/web/.env.local
   • put the same contract address into apps/web/.env.local
   • keep NEXT_PUBLIC_API_URL=http://localhost:8787 (use localhost, not 127.0.0.1, so the session cookie works)
   • for USDC on Sepolia/mainnet you can paste a token address into the UI, or rely on the auto-fill defaults
5. Run API + web:
   • (first time only) pnpm --filter @gh-bounties/api prisma:migrate
   • pnpm --filter @gh-bounties/api dev
   • pnpm --filter @gh-bounties/web dev

Local dev (Sepolia)

1. Set env (root):
   • copy .env.example -> .env
   • set RPC_URL to your Sepolia RPC
   • set CHAIN_ID=11155111
   • (optional) use the existing Sepolia deployment (see Deployments above)
   • set BACKEND_SIGNER_PRIVATE_KEY (used by the API to sign payout authorizations; must match the payoutAuthorizer set at deploy time). Required for deploys.
   • set GitHub OAuth env vars (used by “Login with GitHub” in the web UI)
2. Deploy the contract to Sepolia (once per version):
   • RPC_URL=... PRIVATE_KEY=... pnpm contracts:deploy
   • copy the printed contract address
   • set CONTRACT_ADDRESS to the deployed address (in .env)
3. Set env (web):
   • copy apps/web/.env.local.example -> apps/web/.env.local
   • set NEXT_PUBLIC_CHAIN_ID=11155111
   • set NEXT_PUBLIC_RPC_URL to your Sepolia RPC
   • set NEXT_PUBLIC_CONTRACT_ADDRESS to the deployed address
4. Run API + web:
   • pnpm --filter @gh-bounties/api dev
   • pnpm --filter @gh-bounties/web dev

Deploy (Sepolia / Mainnet)

• Contract deploy prints the deployed address:
  • RPC_URL=... PRIVATE_KEY=... pnpm contracts:deploy
• Recommended: deploy two separate stacks (API + DB + web), one per network.
  • Mainnet stack: CHAIN_ID=1 + mainnet CONTRACT_ADDRESS, its own DATABASE_URL, and WEB_ORIGIN pointing at the mainnet web origin.
  • Sepolia stack: CHAIN_ID=11155111 + Sepolia CONTRACT_ADDRESS, its own DATABASE_URL, and WEB_ORIGIN pointing at the Sepolia web origin.
  • Web network switch (optional): set NEXT_PUBLIC_WEB_ORIGIN_ETHEREUM_MAINNET and NEXT_PUBLIC_WEB_ORIGIN_ETHEREUM_SEPOLIA so users can jump between the two webapps.

Roadmap

• Use zkTLS to reduce trust in our backend that attests with EIP‑712 signatures
• Add DAO UI (contract supports DAO fallback payout/refund after a delay; the Safe can sign with its own UI).
• Add a x.com account to tweet out all bounties
