Struct polkadot_sdk_frame::prelude::frame_system::pallet::config_preludes::SolochainDefaultConfig

pub struct SolochainDefaultConfig;
Expand description

Default configurations of this pallet in a solochain environment.

§Considerations:

By default, this type makes the following choices:

  • Use a normal 32 byte account id, with a DefaultConfig::Lookup that implies no ‘account-indexing’ pallet is being used.
  • Given that we don’t know anything about the existence of a currency system in scope, an DefaultConfig::AccountData is chosen that has no addition data. Overwrite this if you use pallet-balances or similar.
  • Make sure to overwrite DefaultConfig::Version.
  • 2s block time, and a default 5mb block size is used.
