How to setup a multisig & send transactions.

Setup Multisig

First, collect the pubkeys that will be part of the multisig. They can be printed using thorcli:

mayanode keys show person1 --pubkey

Then share the pubkey with the other parties. Each party can add these pubkeys:

mayanode keys add person2 --pubkey {pubkey}

Each party can create the multisig (here a 2/3):

mayanode keys add multisig --multisig person1,person2,person3 --multisig-threshold 2

Create Transaction

Any of the parties can create the raw transaction:

# Sender: maya1ry7jujk4dwjfcrlr2af0e7xeqkgl3esjdqj5v8
# Receiver: maya1y28pn7vlalm5rdq98ssjfq43l6ymnyrp69dd0j
# Amount: 1 CACAO (in 1e10 notation)
mayacli tx bank send maya1ry7jujk4dwjfcrlr2af0e7xeqkgl3esjdqj5v8 maya1y28pn7vlalm5rdq98ssjfq43l6ymnyrp69dd0j 10000000000cacao --chain-id mayachain-mainnet-v1 --node --gas 3000000 --generate-only >> tx_raw.json

This will output a file called tx_raw.json. Edit this file and change the @type field from / to /types.MsgSend.

The tx_raw.json transaction should look like this:


Sign Transaction

The transaction needs to be signed by 2 of the 3 parties (as configured above, when setting up the multisig).

From Person 1

mayanode tx sign --from person1 --multisig multisig tx_raw.json --sign-mode amino-json --chain-id mayachain-mainnet-v1 --node >> tx_signed_1.json

This will output a file called tx_signed_1.json.

From Person 2

mayanode tx sign --from person2 --multisig multisig tx_raw.json --sign-mode amino-json --chain-id mayachain-mainnet-v1 --node >> tx_signed_2.json

This will output a file called tx_signed_2.json.

Build Transaction

Gather Signatures

The party, who wants to broadcast the transaction, needs to gather all json signature files from the other parties.

Multisig Sign

First, get the sequence and account number for the multisig address:


Then combine the signatures into a single one (make sure to update the account number -a and the sequence number -s:

# Account number: 33401 (see curl output)
# Sequence number: 0 (see curl output)
mayanode tx multisign tx_raw.json multisig tx_signed_1.json tx_signed_2.json -a 33401 -s 0 --from multisig --chain-id mayachain-mainnet-v1 --node >> tx.json

This will output a final file called tx.json.

Broadcast Transaction

mayanode tx broadcast tx.json --chain-id mayachain-mainnet-v1 --node --gas auto
