Functions

func BlockGasLimit 

func BlockGasLimit(ctx sdk.Context) uint64

BlockGasLimit returns the max gas (limit) defined in the block gas meter. If the meter is not set, it returns the max gas from the application consensus params. NOTE: see https://github.com/cosmos/cosmos-sdk/issues/9514 for full reference

func GenerateRandomChainID 

func GenerateRandomChainID() string

GenerateRandomChainID returns a random chain-id in the valid format.

func IsEmptyHash 

func IsEmptyHash(hash string) bool

IsEmptyHash returns true if the hash corresponds to an empty ethereum hex hash.

func IsValidChainID 

func IsValidChainID(chainID string) bool

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

func IsZeroAddress 

func IsZeroAddress(address string) bool

IsZeroAddress returns true if the address corresponds to an empty ethereum hex address.

func NewPhotonCoin 

func NewPhotonCoin(amount sdk.Int) sdk.Coin

NewPhotonCoin is a utility function that returns an "aphoton" coin with the given sdk.Int amount. The function will panic if the provided amount is negative.

func NewPhotonCoinInt64 

func NewPhotonCoinInt64(amount int64) sdk.Coin

NewPhotonCoinInt64 is a utility function that returns an "aphoton" coin with the given int64 amount. The function will panic if the provided amount is negative.

func NewPhotonDecCoin 

func NewPhotonDecCoin(amount sdk.Int) sdk.DecCoin

NewPhotonDecCoin is a utility function that returns an "aphoton" decimal coin with the given sdk.Int amount. The function will panic if the provided amount is negative.

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 ProtoAccount 

func ProtoAccount() authtypes.AccountI

ProtoAccount defines the prototype function for BaseAccount used for an AccountKeeper.

func RegisterInterfaces 

func RegisterInterfaces(registry codectypes.InterfaceRegistry)

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

func SetBech32Prefixes 

func SetBech32Prefixes(config *sdk.Config)

SetBech32Prefixes sets the global prefixes to be used when serializing addresses and public keys to Bech32 strings.

func SetBip44CoinType 

func SetBip44CoinType(config *sdk.Config)

SetBip44CoinType sets the global coin type to be used in hierarchical deterministic wallets.

func ValidateAddress 

func ValidateAddress(address string) error

ValidateAddress returns an error if the provided string is either not a hex formatted string address
