A neighbourhood marketplace for real second-hand things. List the lamp, meet the buyer on the driveway — and when you're ready, turn the listing into a real-world asset on-chain. Mint an Item Passport to prove what the thing is and where it's been, then pair it with a companion token and launch it through the Launchpad.
Unaudited beta. On-chain minting, tokens and escrow are switched off — see exactly what's configured.

How a sale actually goes
Photograph the thing
Honest photos, honest condition. Scratches included — buyers trust the dent more than the adjective.
Set a price and an area
Price in ETH or give it away. Show only your general area; the exact address stays private.
Meet and hand it over
Agree a public spot, inspect in person, hand it over. The item is real; so is the handshake.
Optionally keep the record
An Item Passport records what the item was and when it moved. It never claims what it's worth.
From driveway to on-chain
A listing starts as ordinary photos and a description. When you're ready, the Launchpad turns it into a real-world asset (RWA) on Robinhood Chain: it freezes the finalized details, mints an Item Passport to prove what the item is and who listed it, and optionally pairs a fixed-supply companion token you can launch.
The chain never stores the photos themselves. It stores fingerprints — hashes — that let anyone verify the on-chain record against the frozen file. Here's exactly where each piece lives.
On-chain — Robinhood Chain
Permanent, public, verifiable
- The Item Passport token id and its owner — an ERC-721 proving the passport exists and who holds it.
- The immutable listing id, metadata hash and terms hash — fingerprints so anyone can confirm the on-chain record matches the frozen file.
- A metadata URI pointing to the frozen passport JSON, plus the passport's lifecycle status (Listed, Reserved, Collected, Withdrawn, Disputed).
- For a launched companion token: its name, symbol, fixed total supply, balances, and the address permanently paired to one passport. No extra minting, ever.
In storage — off-chain
Readable files, kept private to you
- The actual photo files — full-resolution images, with a SHA-256 of each stored on-chain so they can't be swapped unnoticed.
- The complete frozen passport metadata JSON: title, description, attributes, all image links, disclaimer and terms version.
- Listing terms, seller details, sale offers, and messages — none of this lives on the chain.
- Transaction receipts, block numbers and wallet records — kept only to reconcile and recover your on-chain state.
Minting and token launches stay switched off until the contracts are deployed and audited. See exactly what's configured before you rely on any of it.
