Functions

func BroadcastTx

func BroadcastTx(clientCtx client.Context, 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) (client.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(
	clientCtx gogogrpc.ClientConn, txf Factory, msgs ...sdk.Msg,
) (*tx.SimulateResponse, uint64, error)

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

func ConvertAndEncodeStdTx

func ConvertAndEncodeStdTx(txConfig client.TxConfig, stdTx legacytx.StdTx) ([]byte, error)

ConvertAndEncodeStdTx encodes the stdTx as a transaction in the format specified by txConfig

func ConvertTxToStdTx

func ConvertTxToStdTx(codec *codec.LegacyAmino, tx signing.Tx) (legacytx.StdTx, error)

ConvertTxToStdTx converts a transaction to the legacy StdTx format

func CopyTx

func CopyTx(tx signing.Tx, builder client.TxBuilder, ignoreSignatureError bool) error

CopyTx copies a Tx to a new TxBuilder, allowing conversion between different transaction formats. If ignoreSignatureError is true, copying will continue tx even if the signature cannot be set in the target builder resulting in an unsigned tx.

func GenerateOrBroadcastTxCLI

func GenerateOrBroadcastTxCLI(clientCtx client.Context, flagSet *pflag.FlagSet, msgs ...sdk.Msg) error

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

func GenerateOrBroadcastTxWithFactory

func GenerateOrBroadcastTxWithFactory(clientCtx client.Context, 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(clientCtx client.Context, 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 string, txBuilder client.TxBuilder, overwriteSig bool) error

Sign signs a given tx with a named key. The bytes signed over are canconical. The resulting signature will be added to the transaction builder overwriting the previous ones if overwrite=true (otherwise, the signature will be appended). Signing a transaction with mutltiple signers in the DIRECT mode is not supprted and will return an error. An error is returned upon failure.

func SignWithPrivKey

func SignWithPrivKey(
	signMode signing.SignMode, signerData authsigning.SignerData,
	txBuilder client.TxBuilder, priv cryptotypes.PrivKey, txConfig client.TxConfig,
	accSeq uint64,
) (signing.SignatureV2, error)

SignWithPrivKey signs a given tx with the given private key, and returns the corresponding SignatureV2 if the signing is successful.

func WriteGeneratedTxResponse

func WriteGeneratedTxResponse(
	clientCtx client.Context, 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. Note that this function returns the legacy StdTx Amino JSON format for compatibility with legacy clients. Deprecated: We are removing Amino soon.
