Checking

Open kid/config/config.toml and check up that TCP for the RCP server listen on laddr = "tcp://127.0.0.1:26657"

Change it if it needed and restart the service by the command:

$ sudo systemctl restart kichaind

Check the status:

$ kid status 2>&1 | jq

Install the relayer

Download the archive:

$ wget https://github.com/cosmos/relayer/releases/download/v0.9.3/Cosmos.Relayer_0.9.3_linux_amd64.tar.gz

Unpackage it:

$ tar -zxvf Cosmos.Relayer_0.9.3_linux_amd64.tar.gz

And copy:

$ cp "Cosmos Relayer" /usr/local/bin/rly

Init relayer:

$ rly config init

Edit config.yaml:

Umee key creating:

$ rly keys add umee-betanet-1 umeekey

Output:

{"mnemonic":"_____ ____ ____ ____ ...":"umee1.........................."}

Kichain node key restore:

$ rly keys restore kichain-t-4 kikey "mnemonic divided by space"

Output:

{"mnemonic":"_____ ____ ____ ____ ...":"tki1..........................."}

Adding keys to kichain:

$ rly chains edit umee-betanet-1 key umeekey

$ rly chains edit kichain-t-4 key kikey

Request tokens from Umee faucet at Umee Discord server and check balance:

Umee balance:

$ rly query balance umee-betanet-1

Output:

$ rly query balance umee-betanet-1 100000000uumee

Kichain balance:

$ rly query balance kichain-t-4

Output:

$ rly query balance kichain-t-4 14567355utki

Running relayer

Run clients:

$ rly light init umee-betanet-1 -f $ rly light init kichain-t-4 -f

Output:

$ rly light init umee-betanet-1 -f
successfully created light client for umee-betanet-1 by trusting endpoint http://161.97.78.75:26657
$ rly light init kichain-t-4 -f
successfully created light client for kichain-t-4 by trusting endpoint http://127.0.0.1:26657

Create path from UMEE to KI:

$ rly paths generate umee-betanet-1 kichain-t-4 umee_to_ki_path --port=transfer

Output:

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

Check if everything's ok:

$ rly chains list

Output:

1: kichain-t-4          -> key(✔) bal(✔) light(✔) path(✔)

Open channel from UMEE to KI:

$ rly tx link umee_to_ki_path

If no output - "Channel created", repeat command for opennig the chanel.

Output:
