GenesisState

If you are using a custom chain Common, pass the genesis state.

Pattern 1 (with genesis state see GenesisState for format):

{
  '0x0...01': '0x100', // For EoA
}

Pattern 2 (with complex genesis state, containing contract accounts and storage). Note that in AccountState there are two accepted types. This allows to easily insert accounts in the genesis state:

A complex genesis state with Contract and EoA states would have the following format:

{
  '0x0...01': '0x100', // For EoA
  '0x0...02': ['0x1', '0xRUNTIME_BYTECODE', [[storageKey1, storageValue1], [storageKey2, storageValue2]]] // For contracts
}
