Abstract

This document specifies the x/auth/tx package of the Cosmos SDK.

This package represents the Cosmos SDK implementation of the client.TxConfig, client.TxBuilder, client.TxEncoder and client.TxDecoder interfaces.

Contents

Transactions

TxConfig

client.TxConfig defines an interface a client can utilize to generate an application-defined concrete transaction type. The interface defines a set of methods for creating a client.TxBuilder.

https://github.com/cosmos/cosmos-sdk/blob/v0.47.0-alpha1/client/tx_config.go#L25-L31

The default implementation of client.TxConfig is instantiated by NewTxConfig in x/auth/tx module.

https://github.com/cosmos/cosmos-sdk/blob/v0.47.0-alpha1/x/auth/tx/config.go#L24-L30

TxBuilder

https://github.com/cosmos/cosmos-sdk/blob/v0.47.0-alpha1/client/tx_config.go#L33-L50

The client.TxBuilder interface is as well implemented by x/auth/tx. A client.TxBuilder can be accessed with TxConfig.NewTxBuilder().

TxEncoder/ TxDecoder

More information about TxEncoder and TxDecoder can be found here.

Client

CLI

Query

The x/auth/tx module provides a CLI command to query any transaction, given its hash, transaction sequence or signature.

Without any argument, the command will query the transaction using the transaction hash.

simd query tx DFE87B78A630C0EFDF76C80CD24C997E252792E0317502AE1A02B9809F0D8685

When querying a transaction from an account given its sequence, use the --type=acc_seq flag:

simd query tx --type=acc_seq cosmos1u69uyr6v9qwe6zaaeaqly2h6wnedac0xpxq325/1

When querying a transaction given its signature, use the --type=signature flag:

simd query tx --type=signature Ofjvgrqi8twZfqVDmYIhqwRLQjZZ40XbxEamk/veH3gQpRF0hL2PH4ejRaDzAX+2WChnaWNQJQ41ekToIi5Wqw==
Transactions

The x/auth/tx module provides a convinient CLI command for decoding and encoding transactions.

encode

The encode command encodes a transaction created with the --generate-only flag or signed with the sign command. The transaction is seralized it to Protobuf and returned as base64.

$ simd tx encode tx.json
Co8BCowBChwvY29zbW9zLmJhbmsudjFiZXRhMS5Nc2dTZW5kEmwKLWNvc21vczFsNnZzcWhoN3Jud3N5cjJreXozampnM3FkdWF6OGd3Z3lsODI3NRItY29zbW9zMTU4c2FsZHlnOHBteHU3Znd2dDBkNng3amVzd3A0Z3d5a2xrNnkzGgwKBXN0YWtlEgMxMDASBhIEEMCaDA==
$ simd tx encode tx.signed.json

More information about the encode command can be found running simd tx encode --help.

decode

The decode commands decodes a transaction encoded with the encode command.

simd tx decode Co8BCowBChwvY29zbW9zLmJhbmsudjFiZXRhMS5Nc2dTZW5kEmwKLWNvc21vczFsNnZzcWhoN3Jud3N5cjJreXozampnM3FkdWF6OGd3Z3lsODI3NRItY29zbW9zMTU4c2FsZHlnOHBteHU3Znd2dDBkNng3amVzd3A0Z3d5a2xrNnkzGgwKBXN0YWtlEgMxMDASBhIEEMCaDA==

More information about the decode command can be found running simd tx decode --help.

gRPC

A user can query the x/auth/tx module using gRPC endpoints.
