Overview ¶

Package evmimpl contains the implementation of the `evm` core contract.

The `evm` core contract is responsible for executing and storing:

The github.com/iotaledger/wasp/packages/vm/core/evm/emulator.EVMEmulator.
The ISC magic contract (see iscmagic.go).

See:

The SetInitialState function, which initializes EVM on a newly created ISC chain.
The evm.FuncSendTransaction entry point, which executes an Ethereum transaction.
The evm.FuncCallContract entry point, which executes a view call.

Functions ¶

func MintBlock ¶ added in v1.0.3

func MintBlock(evmPartition kv.KVStore, chainInfo *isc.ChainInfo, blockTimestamp time.Time)

MintBlock "mints" the Ethereum block after all requests in the ISC block have been processed. IMPORTANT: Must only be called from the ISC VM

func Nonce ¶ added in v1.0.3

func Nonce(evmPartition kv.KVStoreReader, addr common.Address) uint64

func SetInitialState ¶ added in v1.0.3

func SetInitialState(evmPartition kv.KVStore, evmChainID uint16, createBaseTokenMagicWrap bool)

SetInitialState initializes the evm core contract and the Ethereum genesis block on a newly created ISC chain.

Types ¶

type StateAccess ¶ added in v1.0.3

type StateAccess struct {
	// contains filtered or unexported fields
}

func NewStateAccess ¶ added in v1.0.3

func NewStateAccess(store kv.KVStoreReader) *StateAccess

func (*StateAccess) Nonce ¶ added in v1.0.3

func (sa *StateAccess) Nonce(addr common.Address) uint64
