v0.14.3 Upgrade Instructions - Monad Documentation

This page contains upgrade instructions for testnet and mainnet. Always verify which network the instructions apply to.

Upgrade notes

No breaking changes. Authenticated UDP is now enforced at the code level — nodes that were already running with it (required since v0.14.0) are unaffected.

1. SSH into the node as `root` user

2. Upgrade monad package

sudo apt update && sudo apt install --reinstall monad=0.14.3 -y --allow-downgrades --allow-change-held-packages
sudo apt-mark hold monad

3. Restart the services and verify

sudo systemctl restart monad-bft monad-execution monad-rpc
sudo systemctl status monad-bft monad-execution monad-rpc --no-pager -l

Expected output: All services should show Active: active (running)

4. Verify the correct version is running

monad-rpc --version

Expected output:

monad-rpc {"commit":"f2a2092b9ba52c4e1fcd333b93fa382e52e44878","tag":"v0.14.3","branch":"","modified":true}
