According to CoinMeta, Wu said that hyperliquid core contributor xulian posted that the latest hip-4 testnet template has been launched on the chain and can be queried through API. The latest version of each template series will be submitted to validators for review and voting in order to be included in the mainnet templates. The template series are distinguished by incremental integer suffixes; for example, binaryprice4 is the latest version of the binaryprice series. After the feedback collection is completed, validators will initialize the templates for deployers to use through on-chain voting, but the instantiation of all templates still needs to wait for hip-4 to be enabled on the mainnet.
