Here you can find sample scripts and notes of how to setup multple EVMOS networks and connect them via an IBC relayer (using Hermes) to transfer tokens & coin cross chain
I wrote hundred lines of comments which explains every steps in each script file and each readme file, hope that helps you guys in exploring Evmos & Cosmos Ecosystem
- Go 1.17.5+
- jq
- yq + tomlq (build on top of jq)
- Rust 1.60+ (for Hermes - IBC relayer)
- docker & docker compose
- Node JS (for Big Dipper 2.0 Cosmos)
I created all of the following samples on an Ubuntu 22.04 LTS machine with 4 CPU 16 GB RAM. It can run
- 2 EVMOS networks
- 1 Hermes as IBC relayer to connect them
- 2 bdjuno & hasura as block explorer's backend & graphql service
- 2 Big Dipper 2.0 as block explorer's backend
without any performance issue (CPU ~20-80% per core, ram ~50% via htop).
- Script to build EVMOS networks and run with docker compose
- Script to build & setup Hermes as an IBC relayer
- Script to setup Big Dipper (backend bdjuno with hasura as graphql service & frontend Big Dipper 2.0 for Cosmos based chains)
You can change their version by updating file env.sh
- This sample is using keyring
test, you may need to change tofilefor secure your test env if needed - You can create
override-env.shfile and override values there
