Feed ids and price objects on Pyth's upgraded Core, the only deployment this SDK targets.
The testnet MarginRegistry was migrated (2026-08-11) off Pyth's beta feed ids and onto
the ids upgraded testnet Core carries, which are the mainnet-style ids — the beta ids
have no upgraded price objects and the upgraded Hermes does not serve them.
DBTC is testnet's wrapped BTC and takes Crypto.XBTC/USD — the same feed mainnet XBTC
uses. The upgraded deployment carries no distinct DBTC feed.
