Supporting Multiple Versions

Quicknode supports multiple versions of Starknet's RPC endpoint. Users can specify the desired version by adding it to the URL path.

Currently supported versions: 0.9, 0.10 (currently 0.10.3-rc.0, a release candidate that is not recommended for production integrations), and the unversioned endpoint, which serves version 0.9.

Removed Versions: RPC versions 0.6, 0.7, and 0.8 have been removed and now return 404. Requests must target /rpc/v0_9 or /rpc/v0_10, or omit the version path to use 0.9. When upgrading from 0.8, note that the pending block tag is now pre_confirmed and starknet_subscribePendingTransactions has been removed.
