Functions

func IsValidChainID

func IsValidChainID(chainID string) bool

IsValidChainID returns false if the given chain identifier is incorrectly formatted.

func IsValidInt256

func IsValidInt256(i *big.Int) bool

IsValidInt256 check the bound of 256 bit number

func ParseChainID

func ParseChainID(chainID string) (*big.Int, error)

ParseChainID parses a string chain identifier's epoch to an Ethereum-compatible chain-id in *big.Int format. The function returns an error if the chain-id has an invalid format

func RegisterInterfaces

func RegisterInterfaces(registry codectypes.InterfaceRegistry)

RegisterInterfaces registers the tendermint concrete client-related implementations and interfaces.

func SafeInt64

func SafeInt64(value uint64) (int64, error)

SafeInt64 checks for overflows while casting a uint64 to int64 value.

func SafeNewIntFromBigInt

func SafeNewIntFromBigInt(i *big.Int) (sdkmath.Int, error)

SafeNewIntFromBigInt constructs Int from big.Int, return error if more than 256bits

Types

type HDPathIterator

type HDPathIterator func() ethaccounts.DerivationPath

func NewHDPathIterator

func NewHDPathIterator(basePath string, ledgerIter bool) (HDPathIterator, error)

HDPathIterator receives a base path as a string and a boolean for the desired iterator type and returns a function that iterates over the base HD path, returning the string.
