Follow this guide to setup Nexis Validator on Devnet, You can do the same on Mainnet once it is live.

​
Requirements

  • Nexis CLI
  • System should be tuned

If any of the above requirements are not met, follow from the following:

Nexis CLI

Install Command Line Interface

System Tuning

Tune system for running Validators

​
Change Nexis CLI configurations

Run the following command to point to devnet

nexis config set --url http://api.devnet.nexis.network:8899
Once the Mainnet will be live you will have to set the configuration to use mainnet native rpc url instead of this one

​
Generate the keypairs

  1. Validator keypair
   nexis-keygen new -o ~/validator-keypair.json
  1. Vote account keypair
    nexis-keygen new -o ~/vote-keypair.json
  1. Withdraw keypair
    nexis-keygen new -o ~/withdraw-keypair.json

​
Fund Validator address

nexis airdrop 10 ~/validator-keypair.json

​
Create vote account

Set validator keypair as default keypair for Nexis CLI

nexis config set --keypair ~/validator-keypair.json

Create a vote account

nexis create-vote-account --commission 8 ~/vote-keypair.json ~/validator-keypair.json ~/withdraw-keypair.json

​
Start validator

Now run the following command to start the validator

nexis-validator \
        --known-validator 5vXaeXtVESpVsA15L4cnce2ZMXvNEVDwfseY34VVK6EB \
        --known-validator HnTZjQX7xUp3hyVACB8FeAdAE3MDAdUUBcVDxFSJpYbZ \
        --entrypoint http://api.devnet.nexis.network:8000 \
        --expected-shred-version 30005 \
        --expected-genesis-hash 8EXN9mquvw6otwQFBJpCed4nk3aM774SPxQjhosDA44U \
        --snapshot-interval-slots 300 \
        --full-snapshot-interval-slots 3000 \
        --identity ~/validator-keypair.json \
        --vote-account ~/vote-keypair.json \
        --ledger ~/ledger/ \
        --dynamic-port-range 8000-10000 \
        --rpc-port 8899 \
        --log ~/nexis-validator.log \
        --no-poh-speed-test \
        --limit-ledger-size 50000000 \
        --log ~/nexis-validator.log

Voila! Your validator is running now, wait for few minutes and it should be visible in the validators list.

You can check it by running the following command

nexis validators

It should output something like this
