Run multiple chains using GM: https://github.com/informalsystems/ibc-rs/tree/master/scripts/gm

[global] 
add_to_hermes=true
home_dir=""

[global.hermes]
binary="/path/to/.hermes/bin/hermes"

[chain1]
gaiad_binary="/path/to/.gm/binarys/simd-v5"
ports_start_at=27000

[chain2]
gaiad_binary="/path/to/.gm/binarys/simd-v4"
ports_start_at=27010

[chain3]
gaiad_binary="/path/to/.gm/binarys/simd-v2"
ports_start_at=27020

[chain4]
gaiad_binary="/path/to/.gm/binarys/simd-v3"
