Proof of case

The cases live in a Steam account. The record of them lives onchain.

What the chain can and cannot do

A Steam item is a row in Valve's database. It cannot be wrapped, bridged or held by a contract, so an onchain treasury of cases is not possible and the site does not pretend otherwise.

What the chain can do is timestamp a claim. Every hour the reserve counts its inventory, hashes the result, and writes that hash to Robinhood Chain. Nobody can change what the reserve said it held an hour ago, which is a weaker guarantee than custody and still a useful one.

The hourly snapshot

The snapshot is the full item list, not just a total, so a change in composition shows up even when the count stays the same. Swapping one case for a different item would produce a different hash.

Checking a snapshot yourself

1. Open the public inventory at CS2_RESERVE_01 and read the item count for Counter-Strike 2.
2. Compare it with the reserve total on the vault page. They should match.
3. Take the snapshot file for the hour you care about and hash it with SHA-256.
4. Look up the transaction on Robinhood Chain and compare the stored hash with yours. A mismatch means the published snapshot is not the one that was timestamped.
