Types

type CheatCodeConfig

type CheatCodeConfig struct {
	// CheatCodesEnabled indicates whether cheat code pre-compiles should be enabled in the chain.
	CheatCodesEnabled bool `json:"cheatCodesEnabled"`

	// EnableFFI describes whether the FFI cheat code should be enabled. Enablement allows for arbitrary code execution
	// on the tester's machine
	EnableFFI bool `json:"enableFFI"`
}

CheatCodeConfig describes any configuration options related to the use of vm extensions (a.k.a. cheat codes)

type TestChainConfig

type TestChainConfig struct {
	// CodeSizeCheckDisabled indicates whether code size checks should be disabled in the EVM. This allows for code
	// size to be disabled without disabling the entire EIP it was introduced.
	CodeSizeCheckDisabled bool `json:"codeSizeCheckDisabled"`

	// CheatCodeConfig indicates the configuration for EVM cheat codes to use.
	CheatCodeConfig CheatCodeConfig `json:"cheatCodes"`

	// SkipAccountChecks skips account pre-checks like nonce validation and disallowing non-EOA tx senders (this is done in eth_call, for instance).
	SkipAccountChecks bool `json:"skipAccountChecks"`

	// ContractAddressOverrides describes contracts that are going to be deployed at deterministic addresses
	ContractAddressOverrides map[common.Hash]common.Address `json:"contractAddressOverrides,omitempty"`
}

TestChainConfig represents the chain configuration.

func DefaultTestChainConfig

func DefaultTestChainConfig() (*TestChainConfig, error)

DefaultTestChainConfig obtains a default configuration for a chain.TestChain. Returns a TestChainConfig populated with default values.

func (*TestChainConfig) GetVMConfigExtensions

func (t *TestChainConfig) GetVMConfigExtensions() *vm.ConfigExtensions

GetVMConfigExtensions derives a vm.ConfigExtensions from the provided TestChainConfig.
