Flow Mainnet will be undergoing an upgrade on Wednesday, 22nd October 2025, from 1 pm to 3 pm UTC (6 am to 8 am PT).

Flow Mainnet will be unavailable between 1 pm to 3 pm UTC on that day.

The public endpoint will be available to read chain data but will not accept any transactions (SendTransaction will be disabled).

ACTIONS needed from node operators on October 22nd, 2025:

  1. If you are running an Access node or EVM GW, please shut down the node(s) by 12:45 am UTC on 22nd October.

  2. For all other node types (Consensus, Collection, Verification, Execution), please shut down your node at 1 pm UTC on 22nd October.

  3. At around 3 pm UTC on 22nd October, a message will be posted on the message forum and on Discord requesting you to start your nodes. Please be on the lookout for the message. Ensure that you have subscribed for updates on the forum page or have joined the Discord #flow-validators channel.

  4. Perform Step 1 and then Step 2 when you see the announcement “Mainnet Spork Complete” on the forum or Discord.

Note: Flow Port will be inaccessible during the duration of this network upgrade, and staking features will be disabled until the completion of the network upgrade.

Please plan accordingly for this Flow network upgrade.

Thank you for your continued support.

Thank you,
