Update
The upgrade is almost complete. 447 nodes are running the Crescendo software and blocks are processing normally.
As a final stage, we suggest that developers test and validate that the upgrade was successful for their contracts through their own access nodes. During this app-testing phase, we request that RPC operators disallow connections to avoid disrupting the tests. This means end-users cannot submit transactions until testing is complete.
The next update will be provided in 3 to 4 hours.

In progress
Scheduled maintenance is currently in progress. We will provide updates as necessary.
🛠️ The Flow network will be in maintenance mode during this upgrade, meaning transactions will not process.
For Developers - Please make sure you're prepared for this upgrade by having your code updated & staged for Cadence 1.0. You can find all the details to do so in here: https://cadence-lang.org/docs/cadence-migration-guide.

Update
7 Days Until The Flow Network Upgrade (Crescendo)
Crescendo is the most significant upgrade to the Flow network since genesis. This upgrade includes full EVM equivalence for all developers on Flow, as well as marking the point of maturity for the Flow native programming environment with Cadence 1.0.

Scheduled
Crescendo is the most significant upgrade to the Flow network since genesis. This upgrade includes full EVM Equivalence for all developers on Flow as well as marking the point of maturity for the Flow native programming environment with Cadence 1.0.
Flow Mainnet Maintenance Flow Mainnet will be upgrading on Wednesday, 4 September 2024, 12pm UTC (5am PT), transitioning from Mainnet 24 to Mainnet 25.
Flow Mainnet will be unavailable between 12pm UTC (5am PT) to 6pm UTC (11am PT) on that day. Please plan accordingly for this Flow network upgrade.
All smart contracts must be upgraded to Cadence 1.0 before the upgrade. To ensure a seamless migration to Cadence 1.0, we are implementing a Cadence 1.0 readiness plan to flag and log transactions with potential breaking code. Starting August 7th, flagged transactions will incrementally face failures, reaching 100% by the time of the Crescendo network upgrade on September 4th, helping developers see if they need to update their smart contracts. Contracts that have been successfully prepared for Cadence 1.0 will not be impacted.
