Midnight Network Locker DApp

A locker dApp holds unshielded NIGHT in a Compact contract until unlockTime (Unix seconds, Uint<64>). No one — including the deployer — can withdraw early. After the deadline, only the beneficiary (proven via witness) can call release and send tokens to a recipient address.

Runnable template: Copy templates/locker-dapp/ for a complete Next.js project (contract + UI). Run npm install && npm run compact && npm run dev after installing the 1AM wallet.

What this skill produces:

• contract/ — Compact locker vault + TypeScript witnesses + compile scripts
• app/locker/ — Next.js client UI (connect, deploy, lock, release, status)
• lib/midnight.ts — wallet session + patched indexer provider (copy from references/midnight-session.md or templates/locker-dapp/lib/midnight.ts)
• lib/locker.ts — deploy, lockTokens, release, ledger decode
• public/zk/locker/ — ZK proving assets synced from contract build

Shared references (canonical provider + troubleshooting — do not duplicate in prompts):

• references/midnight-session.md — createConnectedSession, indexer patch, deploy/call helpers
• references/gotchas.md — preprod deploy hangs, GraphQL offset: null, ZK asset paths
• references/versions.json — pinned @midnight-ntwrk/* versions
