Ibc-transaction-for-kichain

In this article I will tell you how to set up a repeater for cross translation between two networks using the example of Rizon and Kichain For this we need a repeater and two working nodes. Or a relay and one working node and a global rpc from the second network. Or a repeater and a global rpc from two networks. But everything is in order. I will install a repeater for the Rizon node, but you can choose any other method that suits you. The main criterion is that the selected network must have IBC-transfer enabled. This parameter can be checked by entering in the terminal where the node is installed. the following command:  

rizond q ibc-transfer params # (replace rizond with your node's command)

the response should contain the following output:

receive_enabled: true send_enabled: true  

So we found out that the Rizon Network is great for cross transactions. Let's start installing and adjusting the Repeater. Download and install the repeater from the official source Relayer v.1.0.0

git clone https://github.com/cosmos/relayer.git

cd relayer

make install

cd

rly version

output:

version: 1.0.0-rc1–152-g112205b

 

Initializing the repeater

rly config init

create a folder with network configuration and go to it:

mkdir rly_config

cd rly_config

create a settings file for both networks:

nano kichain-t-4.json

copy the content and place it in a file

#we use the global rpc as we put it on vps where the node is not installed locally kichain.

{  "chain-id": "kichain-t-4",   "rpc-addr": "https://rpc-challenge.blockchain.ki:443",    "account-prefix": "tki",   "gas-adjustment": 1.5,   "gas-prices": "0.025utki",   "trusting-period": "48h" }  

similarly, we create a file for the second network, instead of the global rpc, we enter the local one, since the rizon node is located on one server. In theory, you can establish relaying without having a single node, but having a global rpc node of both networks.

nano groot-011.json

{  "chain-id": "groot-011",  "rpc-addr": "http://localhost:26657",   "account-prefix": "rizon",  "gas-adjustment": 1.5,  "gas-prices": "0.025uatolo",  "trusting-period": "48h" }

We parse these settings into the config of the relay:

rly chains add -f groot-011.json

rly chains add -f kichain-t-4.json

cd

we create new wallets or restore the ones you already have:

rly keys add groot-011 name of your wallet 

rly keys add kichain-t-4 name of your wallet

or we restore it with the command:

rly keys restore groot-011 name of your wallet "mnemonic farce from wallet"

rly keys restore kichain-t-4 name of your wallet "mnemonic farce from wallet"

 #You can use the same mnemonic for both wallets, which is very convenient for me :-) the relay will create different wallets based on network settings with different rizon and tki prefixes:

Add the newly created keys to the config of the relay:

rly chains edit groot-011 key name of your wallet

rly chains edit kichain-t-4 key name of your wallet

Let's change the timeout of waiting for confirmation to 30s by changing the standard 10s:

nano ~/.relayer/config/config.yaml

timeout: 30s  

Wallets must be funded on both networks. check the availability of coins with the command:

rly q balance groot-011

rly q balance kichain-t-4

If there are coins on the balance and the relay shows them, then we continue, We initialize the light client in both networks with the command:

rly light init groot-011 -f

rly light init kichain-t-4 -f

We try to generate a channel between the networks with the command:

rly paths generate groot-011 kichain-t-4 transfer  -- port=transfer

#If the command does not work, try several times or add the - debug parameter to see the step-by-step actions of the system the output should be as follows:

Generated path(transfer), run 'rly paths show transfer  -- yaml' to see details

You can open and view the generated settings with the above command.

Trying to open a channel for relaying:

rly tx link transfer  --debug

if it so happens that the channel does not open, then go to the config with the command:

nano /root/.relayer/config/config.yaml

erase the lines in the path section on both networks:

client-id: 07-tendermint-16  connection-id: connection-14  channel-id: channel-11

we re-initialize the light client with the commands:

rly light init groot-011 -f

rly light init kichain-t-4 -f

run the command to open the channel again

 

rly tx link transfer  -- debug

and so on until you see the output of the command:

I[2021–09–06|09:22:54.913] ★ Channel created: [groot-011]chan{channel-11}port{transfer} -> [kichain-t-4]chan{channel-41}port{transfer}

now when calling the command

rly paths list -d

 0: transfer -> chns(✔) clnts(✔) conn(✔) chan(✔) (groot-011:transfer<>kichain-t-3:transfer)

you will see ready to transfer and relay packets.

Well, let's try to perform an cross-network transaction?

rly transact transfer [src-chain-id] [dst-chain-id] [amount] [dst-addr] [flags] 

command template but not as devilish as it is drawn .. in our case the command will look like this:

rly tx transfer groot-011 kichain-t-4 1000000uatolo tki1eakzw0qhxcclerm0uwxae88ugcmet2radufqqf  -- path transfer

and the answer will be a conclusion about a successful hash transaction, which can be checked in both rizon and kichain networks in explorer

I[2021–09–06|09:35:00.471] ✔ [groot-011]@{412926} - msg(0:transfer) hash(D4E8A8C5CA7E6ED0B3FD247C456938E1A160B3E850FB10E27440D25A08C69DAE)

now we will translate in the other direction, the command looks similar

rly tx transfer kichain-t-4 groot-011 1000000utki rizon1eakzw0qhxcclerm0uwxae88ugcmet2raquwh9n  -- path transfer

if you have forgotten wallet addresses. this happens sometimes :-) then you can see the command

rly keys list groot-011

rly keys list kichaint-t-4

Unather way to use Realayer by REMOTE from any kichain node to any wallet in second chain.

first we need to start Relayer permanent we can use tmux or screen but more sensce use service file. let make one

sudo tee /etc/systemd/system/rlyd.service > /dev/null <<EOF [Unit] Description=relayer client After=network-online.target, rizond.service [Service] User=$USER ExecStart=$(which rly) start transfer Restart=always RestartSec=3 LimitNOFILE=65535 [Install] WantedBy=multi-user.target EOF

now make start our service and lets use Relayer remote

sudo systemctl daemon-reload

sudo systemctl enable rlyd

sudo systemctl start rlyd

Use thise comand to transfer

kid tx ibc-transfer transfer transfer channel-N rizon_WALLET_address 1000utki --from name_OF_wallet --fees=5000utki --gas=auto --chain-id kichain-t-4 --home $HOME/kichain/kid

#number of chanel you can see in config.yaml on relayer or use command

rly paths show transfer  -- yaml

Send back to kichain from rizon same comand

rizond tx ibc-transfer transfer transfer channel-N tki_wallet_adress 1000uatolo --from your_wallet_name --fees=5000uatolo --gas=auto --chain-id groot-011

that's probably all.
