Proof
Everything we claim, with a way to check it. This page reads the real contracts on Robinhood Chain and ignores the simulation.
The trail
- 1
Creator fee, onchain
Every $BSTR trade credits a creator fee to the router in the Pons fee escrow.
Check: The escrow's balanceOf(router).
- 2
Harvest
Anyone calls harvest(). The router claims its fees and splits them 90/10 in code.
Check: Harvested events on the router.
- 3
Reserve withdrawal
ETH leaves the reserve only as a numbered withdrawal with a memo.
Check: withdrawal(id) on the reserve.
- 4
Acquisition
The box is logged on-chain with its set number, cost and the withdrawal that paid for it.
Check: acquisition(n) on the reserve.
- 5
Receipt and photos
A metadata file with the redacted receipt and photos; its keccak256 is fixed on-chain.
Check: This page re-hashes every file.
- 6
Proof of custody
The box moves to Vaulted with a dated photo of it on its shelf, next to its vault card.
Check: CustodyUpdated events.
- 7

Custody log
Empty until acquisition #001. Every box gets a row here: what it cost, the withdrawal that paid for it, where it is, and whether its receipt and photos still hash to what the chain recorded.
Withdrawals
No ETH has left the reserve.
The vault card
Every acquisition photo contains a printed card with the vault number, the date and a QR code. Scan it and you land on that box's entry in the log.
From Bag 2, expensive boxes also get a tamper-evident QR and NFC tag on their storage sleeve, never on the box itself, so the tag maps straight to the set, the withdrawal, the receipt and the photos.
