Properties

<Optional> activatePrecompiles

● activatePrecompiles: undefined | false | true

Defined in index.ts:52

If true, create entries in the state tree for the precompiled contracts, saving some gas the first time each of them is called.

If this parameter is false, the first call to each of them has to pay an extra 25000 gas for creating the account.

Setting this to true has the effect of precompiled contracts' gas costs matching mainnet's from the very first call, which is intended for testing networks.

<Optional> allowUnlimitedContractSize

● allowUnlimitedContractSize: undefined | false | true

Defined in index.ts:56

Allows unlimited contract sizes while debugging. By setting this to true, the check for contract size limit of 24KB (see EIP-170) is bypassed
