Functions

func GetDerivativePrice

func GetDerivativePrice(value, tickSize cosmtypes.Dec) cosmtypes.Dec

func GetDerivativeQuantity

func GetDerivativeQuantity(value decimal.Decimal, minTickSize cosmtypes.Dec) (qty cosmtypes.Dec)

func GetSpotPrice

func GetSpotPrice(price decimal.Decimal, baseDecimals int, quoteDecimals int, minPriceTickSize cosmtypes.Dec) cosmtypes.Dec

func GetSpotQuantity

func GetSpotQuantity(value decimal.Decimal, minTickSize cosmtypes.Dec, baseDecimals int) (qty cosmtypes.Dec)

func InitCosmosKeyring

func InitCosmosKeyring(
	cosmosKeyringDir string,
	cosmosKeyringAppName string,
	cosmosKeyringBackend string,
	cosmosKeyFrom string,
	cosmosKeyPassphrase string,
	cosmosPrivKey string,
	cosmosUseLedger bool,
) (cosmtypes.AccAddress, keyring.Keyring, error)

func KeyringForPrivKey

func KeyringForPrivKey(name string, privKey cryptotypes.PrivKey) (keyring.Keyring, error)

KeyringForPrivKey creates a temporary in-mem keyring for a PrivKey. Allows to init Context when the key has been provided in plaintext and parsed.

func NewClientContext

func NewClientContext(
	chainId, fromSpec string, kb keyring.Keyring,
) (client.Context, error)

NewClientContext creates a new Cosmos Client context, where chainID corresponds to Cosmos chain ID, fromSpec is either name of the key, or bech32-address of the Cosmos account. Keyring is required to contain the specified key.

func NewTxConfig

func NewTxConfig(signModes []signingtypes.SignMode) client.TxConfig

NewTxConfig initializes new Cosmos TxConfig with certain signModes enabled.

func NewTxFactory

func NewTxFactory(clientCtx client.Context) tx.Factory
