# Tx

Tx module allows you to sign or broadcast transactions

# Available Commands

Name Description
sign Sign transactions generated offline
broadcast Broadcast a signed transaction to the network
multisign Sign the same transaction by multiple accounts
tx Query for a transaction by hash in a committed block
txs Search for transactions that match the exact given events where results are paginated

# iris tx sign

Sign transactions in generated offline file. The file created with the --generate-only flag.

iris tx sign <file> [flags]

# Flags

Name, shorthand Type Required Default Description
--append bool true true Attach a signature to an existing signature.
--from string true Key name for signature
--offline bool true Offline mode.
--signature-only bool true Print only the generated signature, then exit
--multisig string true Address of the multisig account on behalf of which the transaction shall be signed

# Generate an offline tx

TIP

You can generate any type of txs offline by appending the flag --generate-only

We use a transfer tx in the following examples:

iris tx bank send iaa1w9lvhwlvkwqvg08q84n2k4nn896u9pqx93velx iaa15uys54epmd2xzhcn32szps56wvev40tt908h62 10iris --chain-id=irishub --generate-only

The unsigned.json should look like:

{
    "type": "cosmos-sdk/StdTx",
    "value": {
        "msg": [
            {
                "type": "cosmos-sdk/MsgSend",
                "value": {
                    "from_address": "iaa1w9lvhwlvkwqvg08q84n2k4nn896u9pqx93velx",

                            "amount": "10"
                        }
                    ]
                }
            }
        ],
        "fee": {

        },

        "memo": ""
    }
}

# Sign tx offline

iris tx sign unsigned.json --name=<key-name> > signed.tx

The signed.json should look like:

    "type": "auth/StdTx",

                        }

                                }
                            ]
                        }
                    ]

                }
            ],
            "gas": "200000"
        },
        "signatures": [

                "sequence": "3"
            }
        ],
        "memo": "test"
    }
}

Note the signature in the signed.json should no longer be empty after signing.

Now it's ready to broadcast the signed tx to the IRIS Hub.

# iris tx broadcast

This command is used to broadcast an offline signed transaction to the network.

# Broadcast offline signed transaction

iris tx broadcast signed.json --chain-id=irishub

# iris tx multisign

Sign a transaction by multiple accounts. The tx could be broadcasted only when the number of signatures meets the multisig-threshold.

iris tx multisign <file> <key-name> <[signature]...> [flags]

# Generate an offline tx by multisig key

TIP

No multisig key? Create one

iris tx bank send <from> <to> 10iris --fees=0.3iris --chain-id=irishub --from=<multisig-keyname> --generate-only > unsigned.json

# Sign the multisig tx

# Query the multisig address

iris keys show <multisig-keyname>

# Sign the unsigned.json

Assume the multisig-threshold is 2, here we sign the unsigned.json by 2 of the signers

Sign the tx by signer-1:

iris tx sign unsigned.json --from=<signer-keyname-1> --chain-id=irishub --multisig=<multisig-address> --signature-only > signed-1.json

Sign the tx by signer-2:

iris tx sign unsigned.json --from=<signer-keyname-2> --chain-id=irishub --multisig=<multisig-address> --signature-only > signed-2.json

# Merge the signatures

Merge all the signatures into signed.json

iris tx multisign --chain-id=irishub unsigned.json <multisig-keyname> signed-1.json signed-2.json > signed.json

Now you can broadcast the signed tx.

# iris query tx

iris query tx [hash] [flags]

# iris query txs

iris query txs --events 'message.sender=<iaa...>&message.action=xxxx' --page 1 --limit 30
