💡 What is DareMe?

DareMe turns "I bet you can't..." into a trustless, on-chain smart contract. It's the intersection of SocialFi and Prediction Markets — but instead of betting on external events, you're betting on human action.

Dare your friend to do 50 pushups for 0.1 SOL. Challenge a dev to build a feature in 48 hours. The funds are locked in escrow until the dare is proven — no trust required.

How It Works

CREATE  ──▶  ACCEPT  ──▶  PROVE  ──▶  SETTLE
Stake SOL    Take dare    Film proof   SOL released
in escrow    Clock starts  Upload it    Instantly

1. Create — Challenger creates a dare, describes the task, sets a deadline, and deposits SOL into an on-chain escrow (PDA).
2. Accept — A Daree accepts the challenge. The countdown begins.
3. Prove — The Daree records proof and uploads it. The file hash is stored on-chain.
4. Settle — The Challenger reviews and approves. The smart contract releases escrowed SOL to the Daree.

If the Challenger ghosts, funds are auto-released after the dispute window expires.

Architecture

Layer	Tech	Responsibility
On-Chain	Anchor (Rust)	Escrow, fund locking/release, dare state machine, proof hash storage
Backend	Bun + Express + Prisma	User profiles, dare metadata, media uploads, on-chain indexing, notifications
Frontend	Next.js 16, React 19, Tailwind 4	UI/UX, wallet signing, proof upload, social features

Tech Stack

Component	Technology
Smart Contract	Solana, Anchor (Rust) — 8 instructions, 2 state accounts, PDA escrow
Backend API	Bun, Express, Prisma, PostgreSQL
Frontend	Next.js 16, React 19, Tailwind CSS 4
Authentication	Privy (X/Twitter + embedded wallets)
Media Storage	AWS S3 (presigned uploads)
On-Chain Indexing	Helius Webhooks

Getting Started

Prerequisites

• Rust + Solana CLI
• Anchor >= 0.30
• Bun >= 1.0
• PostgreSQL database

Quick Start

git clone https://github.com/Pratikkale26/dareme.git
cd dareme

# Smart Contract
cd contract && anchor build && anchor test

# Backend API
cd ../api && bun install
cp .env.example .env   # configure DB + S3 + Privy keys
bun run db:migrate && bun run db:generate && bun run dev

# Web Frontend
cd ../web && bun install
cp .env.example .env   # configure API URL + Privy + Program ID
bun run dev

Environment Variables

Backend (api/.env) — DATABASE_URL, AWS_S3_BUCKET, AWS_*, PRIVY_APP_ID, PRIVY_APP_SECRET, SOLANA_RPC_URL, HELIUS_API_KEY

Frontend (web/.env) — NEXT_PUBLIC_API_URL, NEXT_PUBLIC_PRIVY_APP_ID, NEXT_PUBLIC_SOLANA_RPC_URL, NEXT_PUBLIC_PROGRAM_ID

Current Status — MVP ✅

• Anchor smart contract (8 instructions, PDA escrow, 24+ tests)
• Backend API (auth, users, dares, proofs, notifications, webhooks)
• Frontend (dashboard, browse, create, detail, profile, notifications)
• Real Anchor transactions wired (create, accept, approve, reject, cancel, refuse, submit proof)
• Deploy to Devnet (contract deployed, backend/frontend deployment pending)
• Mobile app (post-MVP)

Why Solana?

• ⚡ Sub-second finality — Dares settle instantly
• 💸 Near-zero fees — A $2 dare is viable
• 🌍 Borderless micropayments — Dare anyone, anywhere
• 🔒 Programmable escrow — Trustless by design
