# IBC CLI Usage
# IBC Doubble Hubble
## initialize
## Remove remaining data
```bash
basecoind init # copy the recover key
basecli keys add keyname --recover
basecoind start
```console
> rm -r ~/.chain1
> rm -r ~/.chain2
> rm -r ~/.basecli
```
## transfer
## Initialize both chains
`transfer` sends coins from one chain to another(or itself).
```console
> basecoind init --home ~/.chain1
