Functions

func AddressStoragePrefix

func AddressStoragePrefix(address ethcmn.Address) []byte

AddressStoragePrefix returns a prefix to iterate over a given account storage.

func HeightHashKey

func HeightHashKey(height uint64) []byte

HeightHashKey returns the key for the given chain epoch and height. The key will be composed in the following order:

key = prefix + bytes(height)

This ordering facilitates the iteration by height for the EVM GetHashFn queries.
