IBC-transaction-for-KiChain

Manual for Ibc-transfer from kichain to Cygnusx-Osmo-1 , but can use with any cosmos chain

Here I will describe the process of creating a relayer between two cosmos networks Kichain and osmosis.

PART I. INSTALLATION OF THE NETWORK CLIENT

1. Download and install the network client

git clone https://github.com/osmosis-labs/osmosis
cd osmosis
git checkout v1.0.1
make install
cd ~

2. Create a wallet

chain-maind keys add WALLET_NAME

3. We look at the address of your wallet

chain-maind keys show WALLET_NAME -a

PART II. RELAYER START

1. Download the relayer and install it

git clone https://github.com/cosmos/relayer.git
cd relayer
make install
cd

2. Initializing the relayer

rly config init

3. Let's create a folder in which we will put folders with data for configuring the relayer

mkdir rly_config
cd rly_config

4. We create configs for the networks used:

Ki-chain

nano kichain-t-4_config.json

{
"chain-id": "kichain-t-4",
"rpc-addr": "http://127.0.0.1:26657",
"account-prefix": "tki",
"gas-adjustment": 1.5,
"gas-prices": "0.025utki",
"trusting-period": "48h"
}

save ctrl+x yes enter

Osmosis

nano cygnusx-osmo-1_config.json

{
"chain-id": "cygnusx-osmo-1",
"rpc-addr": "http://54.166.148.90:26657",
"account-prefix": "osmo",
"gas-adjustment": 1.5,
"gas-prices": "0.025uosmox",
"trusting-period": "48h"
}

save ctrl+x yes enter

5. Add pre-written settings to the config file of the relayer

rly chains add -f kichain-t-4_config.json
rly chains add -f cygnusx-osmo-1_config.json
cd

6. We add wallets in both networks to the relayer (it is recommended to create separate wallets for this). Remember to save your seed phrases and addresses

rly keys add kichain-t-4 kidrly
rly keys add cygnusx-osmo-1 osmorly

7. Add the created wallets to the config of the relayer

rly chains edit kichain-t-4 key kidrly
rly chains edit cygnusx-osmo-1 key osmorly

8. Change the waiting timeout in the relayer settings so that it can accurately process transactions

nano ~/.relayer/config/config.yaml

Looking for a line

timeout: 10s

Replace with

timeout: 3m

9. We replenish the purses of the relayer

kid tx bank send WALLET_NAME_KICHAIN_WALLET_ADDRESS 10000000utki --home PATH_TO_YOUR_NODE_DIRECTORY --chain-id kichain-t-4

osmosisd tx bank send WALLET_NAME_OSMO WALLET_ADDRESS_osmorly 10000000uosmox --node http://54.166.148.90:26657/ --chain-id cygnusx-osmo-1 --fees 5000uosmox

10. We check that the tokens have arrived

rly q balance kichain-t-4
rly q balance cygnusx-osmo-1

11. When the tokens arrive on the wallets of the relay, we initialize clients for both networks

rly light init kichain-t-4 -f
rly light init cygnusx-osmo-1 -f

12. We create a tunnel between the two networks.

rly paths generate kichain-t-4 cygnusx-osmo-1 transfer --port=transfer

13. We check that the tunnel was created successfully.

rly paths list -d

you should see the following output

0: transfer             -> chns(✔) clnts(✔) conn(✔) chan(✔) 
(kichain-t-4:transfer<>cygnusx-osmo-1:transfer)

14. create a service file

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

15. We start the service file

sudo systemctl daemon-reload
sudo systemctl enable rlyd
sudo systemctl start rlyd

To check the logs of the relayer, use:

journalctl -u rlyd -f

16. To carry out an ibc transaction, you can use both the subcommands of the relay and, accordingly, the wallets that are added to it, as well as the subcommands of the clients of the networks and the wallets added to them. Examples:

relayer

rly tx transfer kichain-t-4 cygnusx-osmo-1 1000000utki USER_ADDRESS_On_OSMO_NETWORK --path transfer

Client KICHAIN

kid tx ibc-transfer transfer transfer CHANNEL_ID RECIPIENT_ADDRESS IN_OSMO_NET 1000000utki --from WALLET_NAME_KICHAIN --home PATH_TO_YOUR_NODE_DIRECTORY_chain-id kichain-t-4

To get the CHANNEL ID use the command

rly paths show transfer --yaml

You need the value of the channel-id item of the src section

17. After the transaction, we check the balance of the recipient's wallet to make sure that the tokens have arrived

osmosisd q bank balances RECEIVER_ADDRESS_IN_OSMO_NETWORK --node http://54.166.148.90:26657/
