Gaia to Gaia Interblockchain Tx using two different coins
===

### Install GoLang

Add `export PATH=$PATH:/usr/local/go/bin` to `~/.profile` (You can access it by typing in `gedit ~/.profile`). Run `source ~/,profile`. You should have GoLang by now. 

### Install GoLang

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

You now should have `gaiad` available on your command line. (NOTE: `gaiacli` is a deprecated command, use `gaiad` for all purposes). 

### Set up relayer

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

### Set up a local, one node testnet

sudo rm -rf ~/.gaia
gaiad init main --chain-id ibc-1
gaiad keys add acc_1 --recover

Use this key: `fluid cereal trash miracle casino menu true method exhaust pen fiber rural grape purchase rather table omit youth gain cage erase puppy sibling expand`

gaiad add-genesis-account acc_1 10000000000000000000stake
gaiad gentx acc_1 100000000stake --chain-id ibc-1

gaiad collect-gentxs

We are going to run relayer on this chain.

### Use a custom denom `xyz`

cd $HOME/.gaia/config

Now open `genesis.json` and replace all of `stake` with `xyz`. I use VS Code for this.

code genesis.json

Once done, just run the chain once.

gaiad start

> If required, reset the chain using `gaiad unsafe-reset-all`

### Set up the second chain

On another node on the network (or a virtual machine), set up another network. 

sudo rm -rf ~/.gaia
gaiad init main --chain-id ibc-0
gaiad keys add acc_0 --recover

phrase: ```wage thunder live sense resemble foil apple course spin horse glass mansion midnight laundry acoustic rhythm loan scale talent push green direct brick please```

gaiad add-genesis-account acc_0 10000000000000000000stake
gaiad gentx acc_0 100000000stake --chain-id ibc-0

gaiad collect-gentxs
gaiad start

You can use other denoms apart from `stake`. I personally use `xyz` on `ibc-1` chain.

### Set up relayer on `ibc-1`

Make a folder and inside of it, create two more folders,  `path` and `relayerChains`. For each chain, create a JSON file inside relayerChains such as this.

#### relayerhains/ibc-0.json

{
"key":"acc_0",
"chain-id":"ibc-0",
"rpc-addr":"http://localhost:26657",
"account-prefix":"cosmos",
"gas-adjustment":1.5,
"gas-prices":"0.025stake",
"trusting-period":"336h"
}

#### relayerChains/ibc-1.json

{
"key":"acc_1",
"chain-id":"ibc-1",
"rpc-addr":"http://[IP ADDRESS OF OTHER NETWORK]:26657",
"account-prefix":"cosmos",
"gas-adjustment":1.5,
"gas-prices":"0.025xyz",
"trusting-period":"336h"
}

Now in `path` folder, create a `path.json`  file.

#### path/path.json

{
"src":{
"chain-id":"ibc-0",
"client-id":"",
"connection-id":"",
"channel-id":"",
"port-id":"transfer",
"order":"unordered",
"version":"ics20-1"
},

"dst":{
"chain-id":"ibc-1",
"client-id":"",
"connection-id":"",
"channel-id":"",
"port-id":"transfer",
"order":"unordered",
"version":"ics20-1"
},

"strategy":{
"type":"naive"
}
}

Now let's configure `relayer`.

1. `rly config init` (If a config file already exists, delete the .relayer file in $HOME)

2. `rly config add-chains path_to_folder/relayerChains `

3. `rly keys restore ibc-0 acc_0 "wage thunder live sense resemble foil apple course spin horse glass mansion midnight laundry acoustic rhythm loan scale talent push green direct brick please`" --coin-type 118

4. `rly keys restore ibc-1 acc_1 "fluid cereal trash miracle casino menu true method exhaust pen fiber rural grape purchase rather table omit youth gain cage erase puppy sibling expand"  --coin-type 118

5. `rly config add-paths path_to_folder/path`

> TIP: You can use `pwd` to find the path of the current folder.

6. `rly light init ibc-0 -f`

7. `rly light init ibc-1 -f`

8. See if the chains are ready to relay over: `rly chains list`

9. See the current status of the path you will relay over: `rly paths list`

10. Connect the two chains: `rly tx link path -d -o 3s`

11. Check balances on two chains:` rly q bal ibc-0` and `rly q bal ibc-1`

12. `rly tx transfer ibc-0 ibc-1 1000000xyz $(rly chains address ibc-1)`

> In the screenshot below, `pCrust-1` is equivalent to `ibc-0`.
