Python bitcoin RPC lib which worked for me from box and took ~30 seconds to read doc and install:

pip3 install python-bitcoinrpc

ipython3

rpc_connection = AuthServiceProxy("http://%s:%s@127.0.0.1:56212"%("user3150903419", "passe8fe2d8aa38c4e6faca129c6f3a6261a605e72a76eff36f2a5897dc7a03c2878b9"))
get_info = rpc_connection.getinfo()
print(get_info)

sudo yum install build-essential pkg-config libc6-dev m4 g++-multilib autoconf libtool ncurses-dev unzip git python python-zmq zlib1g-dev wget libcurl4-gnutls-dev bsdmainutils automake curl
Installed partial packages which have similar name in CentOS reps ^^ (just copypasted from Ubuntu installation manual as step0 so most of the packages above will not be installed)

sudo yum groupinstall 'Development Tools'
Then run ^^ to install most of the deps

sudo yum install git pkgconfig automake autoconf ncurses-devel python wget gtest-devel gcc libtool patch lbzip2 curl-devel
more deps ^^

"""
Node preparation for gateway binding:
1) Starting and syncing KMD
2) Starting gw testing assetchain with valid pubkey
3) Import privkey from assetchain to KMD chain
4) Save pubkey on assetchain, wallet address and IP as output in text file
5) Mine until balance >0, to have some coins for oracle subscribe, then stop mining
5) Register as oracle publisher and subscribe X times, wait until these transactions mined

Wikipedia: Multisignature (often called multisig) is a form of technology used to add additional security for cryptocurrency transactions. Multisignature addresses require another user or users sign a transaction before it can be broadcast onto the block chain.

In this short guide will be demonstrated 2of2 multisignature wallet creation and usage. I'll use 2 nodes and Komodo assetchain. On KMD main chain steps will be same, just not use `-ac_name` param. 

Step 1

At first lets get addresses on two nodes which we will combine the into single mutlisig address. Also we will need pubkey and privkey (wif) for each address:
