Reserves
Every mirror on Tempo should be backed by a token locked on Robinhood Chain. The check, and where it stands.
The check
For each ticker, two numbers on two chains should agree:
| Robinhood Chain | Tempo |
|---|---|
What the ticker's StockLockbox has outstanding towards Tempo — its outstanding per destination, readable through reserveView() | The mirror's total supply, which only the adapter can change, by minting on arrival and burning on the way out |
By design, supply on Tempo never exceeds what was locked — the invariant tests hold it on both paths, direct and through the testnet hop: the adapter mints only on a verified LayerZero message from the lockbox's side, and a credit it can't mint is deferred rather than minted elsewhere. Tokens in flight, sent but not yet delivered, are the only honest gap, and the check will name them.
The reserves screen
Reserves — Backing in More — reads Robinhood Chain, Base and Tempo in your browser, ticker by ticker, at stated blocks, and gives one verdict:
| Verdict | When |
|---|---|
| Backed | Every check passed: the lockbox holds what it owes, and what it owes equals the mirror's supply, held credits, the hop on Base and what is in flight |
| Short | A check failed; the ticker says which |
| Partial | A check couldn't run — it is never passed by assumption |
On Tempo alone two more checks hold: only the adapter mints — supply equals its net mints, and no one else holds the mirror's issuer role — and supply stays within the cap. Re-check reads every chain again in your browser. Ops' reserve-watch keeps a snapshot every 5 minutes and alerts when a check fails or anyone but the adapter can mint; the screen shows 30 days of it.
Where it stands
The verdict on testnet is Partial: the Robinhood-side lockboxes are not deployed yet (they wait on testnet ETH, an owner action). On 13 October reserve-watch read "5 tickers partial at Tempo #39388481 · Robinhood side not deployed" (evidence/ops-health-2026-10-13.json). The Tempo side checks out: on 12 October, at Moderato block 39,326,334, all five mirrors had a supply of zero, nothing deferred, net mints of zero, and the adapter alone held each issuer role (acceptance/R4-12.md; supplies also in evidence/mirror-supplies-2026-10-12.json).
Separately, the house reserves you can supply — the maker vault, Range, Parlay and Boost — show their own balance sheets on Earn.
