Announcements

Hi all, we have released a new version of Bor (`v2.8.0`) and Erigon (`v3.6.0`) for Polygon PoS Mainnet.

This release includes the changes required for the upcoming Chicago hardfork that updates gas pricing for selected EVM opcodes and precompiles. These changes improve gas-cost alignment with execution cost and help maintain network stability.

All validators, RPC providers, node operators, and infrastructure partners should upgrade their Bor nodes before the hardfork activation block.

Activation:

  • Mainnet: block 87218600 at 2026-05-21 14:00 UTC

Steps to upgrade bor

  1. Stop bor service
sudo service bor stop
  1. Install Bor with a version tag, network name (mainnet), and node type (sentry, validator, or archive).
# Replace the node type
curl -L <https://raw.githubusercontent.com/maticnetwork/install/main/bor.sh> | bash -s -- v2.8.0-beta <network> <node_type>
  1. Check bor version
/usr/bin/bor version
# It should print
# Version: 2.8.0-beta
  1. Restart bor service
sudo service bor start
