tx

func BroadcastTx ¶

func BroadcastTx(ctx context.CLIContext, txf Factory, msgs ...sdk.Msg) error

BroadcastTx attempts to generate, sign and broadcast a transaction with the given set of messages. It will also simulate gas requirements if necessary. It will return an error upon failure.

func BuildSimTx ¶

func BuildSimTx(txf Factory, msgs ...sdk.Msg) ([]byte, error)

BuildSimTx creates an unsigned tx with an empty single signature and returns the encoded transaction or an error if the unsigned transaction cannot be built.

func BuildUnsignedTx ¶

func BuildUnsignedTx(txf Factory, msgs ...sdk.Msg) (context.TxBuilder, error)

BuildUnsignedTx builds a transaction to be signed given a set of messages. The transaction is initially created via the provided factory's generator. Once created, the fee, memo, and messages are set.

func CalculateGas ¶

func CalculateGas(
	queryFunc func(string, []byte) ([]byte, int64, error), txf Factory, msgs ...sdk.Msg,
) (sdk.SimulationResponse, uint64, error)

CalculateGas simulates the execution of a transaction and returns the simulation response obtained by the query and the adjusted gas amount.

func GenerateOrBroadcastTx ¶

func GenerateOrBroadcastTx(ctx context.CLIContext, msgs ...sdk.Msg) error

GenerateOrBroadcastTx will either generate and print and unsigned transaction or sign it and broadcast it returning an error upon failure.

func GenerateOrBroadcastTxWithFactory ¶

func GenerateOrBroadcastTxWithFactory(ctx context.CLIContext, txf Factory, msgs ...sdk.Msg) error

GenerateOrBroadcastTxWithFactory will either generate and print and unsigned transaction or sign it and broadcast it returning an error upon failure.

func GenerateTx ¶

func GenerateTx(ctx context.CLIContext, txf Factory, msgs ...sdk.Msg) error

GenerateTx will generate an unsigned transaction and print it to the writer specified by ctx.Output. If simulation was requested, the gas will be simulated and also printed to the same writer before the transaction is printed.

func Sign ¶

func Sign(txf Factory, name, passphrase string, tx context.TxBuilder) ([]byte, error)

Sign signs a given tx with the provided name and passphrase. If the Factory's Keybase is not set, a new one will be created based on the client's backend. The bytes signed over are canconical. The resulting signature will be set on the transaction. Finally, the marshaled transaction is returned. An error is returned upon failure.

Note, It is assumed the Factory has the necessary fields set that are required by the CanonicalSignBytes call.

func WriteGeneratedTxResponse ¶

func WriteGeneratedTxResponse(
	ctx context.CLIContext, w http.ResponseWriter, br rest.BaseReq, msgs ...sdk.Msg,
)

WriteGeneratedTxResponse writes a generated unsigned transaction to the provided http.ResponseWriter. It will simulate gas costs if requested by the BaseReq. Upon any error, the error will be written to the http.ResponseWriter.
