Hello Everyone,

We have released heimdall v0.10.0 for Polygon mainnet. This release includes mainly improvements and fixes.
It also defines the Ithaca HF, with activation heights:

  • Amoy at block 40,776,000 (2026-07-20 ~14:00 UTC) :white_check_mark: completed
  • Mainnet at block 50,185,000 (2026-07-29 ~14:00 UTC)

Action required: All node operators must upgrade as soon as possible to ensure compatibility and network safety.

Steps to upgrade

  1. Stop heimdall service
    sudo service heimdalld stop
  2. Install heimdall with a version tag, network name (mainnet), and node type (sentry, validator).
    3.Replace the node type
    curl -L https://raw.githubusercontent.com/maticnetwork/install/heimdall-v2/heimdall-v2.sh | bash -s – v0.10.0 mainnet sentry
    (swap sentry → validator if this is a validator node)
  3. Check heimdall version
    sudo /usr/bin/heimdalld version
    It should print 0.10.0
  4. Restart heimdall service
    sudo service heimdalld start
