Playces

Show up. Play. Earn. Playces turns real-world venues into interactive social arenas — geofenced check-ins, embedded wallets, onchain mini-games (like the 67), chain/product airdrops, and collectible onchain rewards on Base.

Attendees check in at a venue, onboard with email (embedded wallet via Privy), play sponsor-skinned mini-games head-to-head, rep their favorite chain, and collect a memorable onchain reward. The reward reveal shows a 3D collectible artifact.

Be there. Play. Earn your moment.

Features

• Gamified venue experience — bold arcade UX, mobile-first, light & dark.
• Email onboarding via Privy — embedded wallets created instantly, no seed phrases. Attendees fund USDC on the settlement chain through Privy's useFundWallet (card / exchange onramp), then stake a match via Blink.
• ENS subname tickets — attendees pick a custom label (e.g. alice) and claim an event-scoped ENSv2 subname (alice-ethglobal-nyc.playce.eth) on Sepolia. The backend registers it on the Permissioned Registry (with Enhanced Access Control roles for renew / resolver / subregistry) and writes addr, tier, event, description, and url on the Permissioned Resolver. Gas is sponsored; there is no Preview mock when minting is disabled.
• Geofenced check-in — location permission → "inside / outside zone" → check in, with clear fallback states.
• Mini-games hub — including the 67: two players stake p2p, the camera opens with a sponsor AR skin (Chainlink / Pyth / Blink), and they throw the 67 — best score wins the pot.
• Rep your chain + airdrops — sponsors drop rewards to attendees at the venue.
• Onchain reward mint — viem/wagmi-shaped states (preparing → signing → submitting → confirming → success).
• 3D reward reveal + shareable collectible page + rewards gallery.

Getting started

# 1. Install dependencies
npm install

# 2. Configure Privy
cp .env.example .env.local
# then set NEXT_PUBLIC_PRIVY_APP_ID=... from https://dashboard.privy.io

# 3. Run the dev server
npm run dev

Open http://localhost:3000.

ENS v2 tickets (Sepolia Continuity)

Claim lives on /event/[slug] (catalog events). Attendees pick a custom label; the server calls Permissioned Registry register then Permissioned Resolver multicall on Sepolia. Requires all of:

ENS_SUBNAME_ENABLED=true
ENS_REGISTRY_ADDRESS=...
ENS_RESOLVER_ADDRESS=...
ENS_CHAIN_ID=11155111
ENS_PARENT_NAME=playce.eth
NEXT_PUBLIC_ENS_ENABLED=true
NEXT_PUBLIC_ENS_PARENT_NAME=playce.eth
MINTER_PRIVATE_KEY=...   # must own playce.eth in the registry
SEPOLIA_RPC_URL=...      # or NEXT_PUBLIC_SEPOLIA_RPC_URL

If minting is not configured, /api/ens/ticket returns 503 (no Preview ticket). Demo registration: btcvibhav-ethglobal-nyc.playce.eth.

Privy USDC funding (financial flow)

Sign in with email/Google → Privy creates an embedded wallet → Fund USDC opens Privy's funding modal (useFundWallet) onto Base USDC → stake a chess or 67 match via Blink. The fund button lives on the profile wallet card, account menu, and both stake screens.

Smart contracts & onchain rewards

Deployed addresses and demo transactions are listed above. The sections below cover each contract's role, source verification, and local/testnet deploys.

Contract overview

PlaycesPass (contracts/src/PlaycesPass.sol)

• ERC-721 (ERC721URIStorage + AccessControl).
• One claim per (eventId, wallet) — enforced onchain.
• Soulbound — non-transferable proof you were there.
• mintClaim(to, eventId, uri) gated by MINTER_ROLE.

Used on Base mainnet for geofenced memory clips and on Arbitrum Sepolia for direct chain-battle win badges.

StakeEscrow (contracts/src/StakeEscrow.sol)

• Holds Blink-deposited USDC on Base mainnet.
• Credits stakes per battle room; settle(roomId, winner) pays the pot to the winner when they claim via /api/reward/claim.

ProofSender / ProofReceiverPass

• Chainlink CCIP cross-chain mint path for Ethereum-repped chain-battle wins.
• Backend holds SENDER_ROLE on ProofSender; receiver mints soulbound badges on Ethereum Sepolia when the CCIP message arrives.

Verify source code

Re-submit or refresh Sourcify verification (syncs to Blockscout):

bash contracts/verify-all.sh

Or verify one contract manually:

cd contracts
forge verify-contract 0xC1eF7A81195538bc529b8Ed42182eC73764450FC \

Deploying locally / testnets

# Deploy PlaycesPass + StakeEscrow to Base Sepolia (dev)
bash contracts/deploy.sh

# Deploy CCIP sender/receiver + badge contracts (testnets)
bash contracts/deploy-ccip.sh
bash contracts/deploy-badge.sh

Wire addresses into .env.local (see .env.example) and restart the dev server.

The 67 game

/play/67 is a full chain-battle mini-game: event-gated lobby, Blink USDC staking, sponsor AR skins (Chainlink / Pyth / Arbitrum / Ethereum), camera-based scoring, solo high-score mode, and onchain win badges + pot settlement via /api/reward/claim.
