Proof of Purpose

An on-chain youth impact protocol. Donors fund a transparent USDC treasury. Trusted partner orgs (Catalysts) propose real-world bounties. Youth (Champions) show up and do the work. A Catalyst verifies attendance in person via QR scan — the scan is the on-chain proof. $PURPOSE is minted directly to the Champion's wallet, redeemable 1:1 for USDC at approved local Vendors.

Built on Base. Open-source under AGPL-3.0. Designed to be forked city-by-city.

Why this exists

Most youth-incentive programs are opaque: cash gets handed out, paperwork piles up, and donors never see where their dollar landed. Proof of Purpose puts the entire loop on-chain — donation → bounty → verified attendance → youth reward → local-business spend — so every step is publicly auditable in real time. No prepaid cards, no spreadsheets, no trust-us.

Champions don't need a wallet, a seed phrase, or a crypto background. They sign in by email, Google, Apple, or passkey; a smart wallet is created silently with sponsored gas. From their perspective: tap ENTER, do the work, get paid at a vendor down the street.

Status

• ✅ V1 live on Base mainnet, funding flow active.
• 🛠 V2 contracts (PurposeTokenV2, BountyManagerV2, VendorRedemptionV2) finalized — pending mainnet redeploy. See contracts/DEPLOYMENT.md.
• 🛠 On-chain governance (1 active monthly membership NFT = 1 vote) pending deploy of the thirdweb Vote contract + vPURPOSE shadow token. Current in-app tally is the interim source of truth.
• ⏸ Tax-deductibility for donors paused pending federal clarity for on-chain charitable structures (e.g. the CLARITY Act).

Stack

• Frontend — React 18, Vite, TypeScript, Tailwind, brutalist design system
• Wallets — thirdweb in-app smart wallets (email / Google / Apple / passkey, sponsored gas) for users; EOA (MetaMask / Coinbase / WalletConnect) for admins
• Chain — Base mainnet (chainId 8453), USDC-denominated treasury
• Backend — Lovable Cloud: Postgres + RLS, edge functions, storage, auth
• Settlement — server-side signer holds SETTLEMENT_ROLE; vendors and champions never broadcast their own transactions

Open source

Licensed under AGPL-3.0. Forks must stay open. The brand ("Proof of Purpose", $PURPOSE wordmark, visual identity in src/assets/) is reserved — please rebrand before launching.

If you want to run this protocol in your city, start with FORKING.md — the full deploy takes about a day on testnet and another half-day on mainnet.

Contracts

Live addresses live in src/config/contracts.ts. Full deploy guide in contracts/DEPLOYMENT.md.
