Prices, data & oracles

Straight answer: Gloam does not use an on-chain price oracle yet. Marks in the app are display data. Swaps that hit a DEX use the pool’s own spot price.

Do you use Chainlink / Pyth / RedStone?

No. Nothing in the contracts reads those feeds today. If someone asks on a call, that is the honest one-liner.

What prices you see in the app

Stocks, Yahoo Finance chart API for the mark and sparkline (server-side). If Yahoo fails, the app falls back to a static catalog number.
ETH, CoinGecko simple price + 30-day chart for USD conversion and portfolio.
Memes (mainnet path), DexScreener discovery is gated off until mainnet product ships.

These are display marks only. They are not binding settlement prices on Robinhood Chain.

What sets execution price

Public / adapter swaps, Uniswap-style router getAmountsOut on the live AMM pool (spot price in that pool).
Sealed private trade, public rateIn / rateOut (coarsened display marks). Size is private: amountOutMin defaults to a 1-wei floor so it does not equal your real output. Pair and caller are still public.
Vault inventory, cash out needs the vault to actually hold the asset (deposited[asset]). Private trade can mint a note; unshield still needs inventory.

What ships next for pricing

Bind sealed rates to a real source (target: Pyth for equities-style feeds, or AMM mid when a deep pool exists).
Seed and show vault inventory per faucet stock so cash-out is safe.
Never claim oracle security until the feed is on-chain and checked.

Balances and history

Wallet balances, on-chain (viem / wallet).
Vault notes, local secrets + on-chain tree; backup in Settings.
Public activity, explorer / RPC logs for open transfers.
