Functions

func Bytes2Hex

func Bytes2Hex(d []byte) string

Bytes2Hex returns the hexadecimal encoding of d.

func CopyBytes

func CopyBytes(b []byte) (copiedBytes []byte)

CopyBytes returns an exact copy of the provided bytes.

func CreateAddress

func CreateAddress(addr sdk.AccAddress, nonce uint64) sdk.AccAddress

func CreateAddress2
