Functions

func IsValidChainID

func IsValidChainID(chainID string) bool

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

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.SysCoin

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() exported.Account

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

func RegisterCodec

func RegisterCodec(cdc *codec.Codec)

RegisterCodec registers the account interfaces and concrete types on the provided Amino codec.

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.

Types

type Code

type Code []byte

Code is account Code type alias

func (Code) String

func (c Code) String() string

type EthAccount

type EthAccount struct {
	*authtypes.BaseAccount `json:"base_account" yaml:"base_account"`
	CodeHash               []byte `json:"code_hash" yaml:"code_hash"`
}

EthAccount implements the auth.Account interface and embeds an auth.BaseAccount type. It is compatible with the auth.AccountKeeper.

func (EthAccount) Balance

func (acc EthAccount) Balance(denom string) sdk.Dec

Balance returns the balance of an account.

func (EthAccount) EthAddress

func (acc EthAccount) EthAddress() ethcmn.Address

EthAddress returns the account address ethereum format.

func (EthAccount) MarshalJSON

func (acc EthAccount) MarshalJSON() ([]byte, error)

MarshalJSON returns the JSON representation of an EthAccount.

func (EthAccount) MarshalYAML

func (acc EthAccount) MarshalYAML() (interface{}, error)

MarshalYAML returns the YAML representation of an account.

func (*EthAccount) SetBalance

func (acc *EthAccount) SetBalance(denom string, amt sdk.Dec)

SetBalance sets an account's balance of the given coin denomination.

CONTRACT: assumes the denomination is valid.

func (EthAccount) String

func (acc EthAccount) String() string

String implements the fmt.Stringer interface

func (*EthAccount) UnmarshalJSON

func (acc *EthAccount) UnmarshalJSON(bz []byte) error

UnmarshalJSON unmarshals raw JSON bytes into an EthAccount.
