Bor v2.7.0-beta2 and Erigon v3.5.0-beta2 for Amoy

[Mayank_Singhal]

Hi everyone,

We have released a new beta version of Bor v2.7.0-beta2 and Erigon v3.5.0-beta2.

This release schedules the Giugliano Hard Fork for Amoy.

The Giugliano Hard Fork on Amoy is scheduled for block number 35573500. Which is expected to hit at Mar-23-2026 2 PM UTC. Make sure to update all your Amoy nodes before this time.

Steps for upgrading Bor node

1. Stop bor service

   sudo service bor stop
   
   

2. Install Bor with a version tag, network name (amoy, 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 -- v2.7.0-beta2 <network> <node_type>
   
   

3. Check bor version

   /usr/bin/bor version
   
   # It should print 
   # v2.7.0-beta2
   
   

4. Restart bor service

   sudo service bor start
