Creating a Multisig

The IOV Name Service supports multisig account

Once you have created your addresses, you can create a multisig address from multiple addresses with the flags --multisig and --multisig-threshold

iovnscli keys add ben_multikey --multisig=benkeys,benkeys2,benkeys3 --multisig-threshold=2 

Flag	Description
--multisig	the list of addresses which can sign the multisig
--multisig-threshold	the minimum number of signatures required to validate a multisignature

You can check that the multisig has been created correctly by showing it

iovnscli keys show ben_multikey
{
  "name": "ben_multikey",
  "type": "multi",
  "address": "star124etu3nt55t039ytg7ft72nprum52f9wyhljf7",
