Collectively-unlockable encrypted content — crowdfunding for knowledge.
Content is encrypted and stored publicly. N people must each contribute before anyone can read it. Each contribution is an on-chain receipt. Progressive reveals at 25/50/75% build collective confidence before full unlock.
The question isn't "is this article worth $5 to me?" but "is this article worth $5 to 10 of us?"

- Lockbox.sol — Individual lockbox with threshold-based collective unlock, progressive reveal levels (0-4), contribution tracking, excess refund, and author withdrawal
- LockboxFactory.sol — Factory pattern for deploying and registering lockbox instances, with per-author tracking
- Access control conditions tied to on-chain contract state (
isUnlocked()) - Content encrypted client-side, decryption key released by Lit network nodes only when the contract reports threshold reached
- No single entity holds the key or can censor the unlock
- Encrypted content blobs stored on IPFS with content-addressed CIDs
- Public metadata (title, abstract, tags, word count) stored separately and always accessible
- Progressive teaser CIDs revealed at 25/50/75% milestones
- Agent manifest (
agent.json) with ERC-8004 registration - Each contribution generates an on-chain reputation receipt
- Self-custody transfer of ERC-8004 identity NFT
- HTTP 402 payment flow on Tempo for gating lockbox content
- Server returns metadata for free, requires 0.01 pathUSD payment for full content
- Client pays on-chain via
mppxSDK, receives content +Payment-Receiptheader - Tested end-to-end on Tempo testnet
- Landing page — Philosophy, for-humans/for-agents toggle, architecture breakdown
- App page — Connect wallet, view lockbox progress, contribute with tip multiplier controls
- Create page — Form to deploy new lockboxes across all 5 networks
- Network switching between Base, Tempo, Base Sepolia, Status Sepolia, Tempo Testnet
Lockbox is designed for machine participants, not just humans.
Public metadata (title, abstract, tags, word count) is always accessible. Agents can semantically search, cite, and reference lockbox content without paying to read it. The metadata is structured JSON, not HTML scraping.
An agent with a wallet can call contribute() on any lockbox. The contribution amount is fixed and readable from the contract (contributionAmount()). The agent can check hasContributed(address) before paying, and getProgress() to assess whether a lockbox is worth funding.
getRevealLevel() returns 0-4, letting agents gauge how close a lockbox is to unlock. An agent managing a knowledge acquisition budget can prioritize lockboxes near their threshold — where one more contribution completes the unlock for everyone.
Agents can access lockbox content through the MPP server endpoint. The flow is standard HTTP:
GET /contentreturns402 Payment Requiredwith aWWW-Authenticate: Paymentheader- Agent pays on-chain (Tempo) via
mppxclient - Server validates payment, returns content with
Payment-Receiptheader
Each contribution is recorded on-chain. With ERC-8004, agents build a verifiable history of knowledge contributions — a reputation signal that other agents can query before deciding to collaborate or transact.
