Submitting your GenTx for the Evmos Incentivized Testnet

Thank you for becoming a genesis validator on Evmos! This guide will provide instructions on setting up a node, submitting a gentx, and other tasks needed to participate in the launch of the Evmos Olympus Mons incentivized testnet.

A gentx does three things:

  • Registers the validator account you created as a validator operator account (i.e. the account that controls the validator).
  • Self-delegates the provided amount of staking tokens.
  • Links the operator account with a Tendermint node pubkey that will be used for signing blocks. If no --pubkey flag is provided, it defaults to the local node pubkey created via the evmosd init command.

Setup

Software:

To verify that Go is installed:

go version
# Should return go version go1.17 linux/amd64

Instructions (Until November 19, 2021 12AM PST)

These instructions are written targeting an Ubuntu 20.04 system. Relevant changes to commands should be made depending on the OS/architecture you are running on.

  1. Install evmosd

    git clone https://github.com/tharsis/evmos
cd evmos && git checkout tags/v0.3.x
make install

    Make sure to checkout to some v0.3.x tag.

    Verify that everything is OK. If you get something like the following, you've successfully installed Evmos on your system.

    evmosd version --long

name: evmos
server_name: evmosd
version: '"0.3.0"'
commit: 7ad7715c59ec38fd19c06de54d03a982afebf961
build_tags: netgo,ledger
go: go version go1.17 darwin/amd64

  2. Initialize the evmosd directories and create the local file with the correct chain-id

    evmosd init <moniker> --chain-id=evmos_9000-2

  3. Create a local key pair in the keybase

    evmosd keys add <your key name>

    Make sure to keep mnemonic seed which will be used to receive rewards at the time of mainnet launch.

  4. Add the account to your local genesis file with a given amount and key you just created.

    evmosd add-genesis-account $(evmosd keys show <your key name> -a) 1000000000000aphoton

    Make sure to use aphoton denom, not photon.

  5. Create the gentx

    evmosd gentx <your key name> 1000000000000aphoton \
  --chain-id=evmos_9000-2 \
  --moniker=<moniker> \
  --details="My moniker description" \
  --commission-rate=0.05 \
  --commission-max-rate=0.2 \
  --commission-max-change-rate=0.01 \
  --pubkey $(evmosd tendermint show-validator) \
  --identity="<Keybase.io GPG Public Key>"

  6. Create Pull Request to the repository (tharsis/testnets) with the file olympus_mons/gentxs/<your validator moniker>.json. In order to be a valid submission, you need the .json file extension and no whitespace or special characters in your filename. Your PR should be one addition.
