In progress
The Testnet upgrade is now underway!

This is the Crescendo network upgrade, which brings EVM Equivalence and Cadence 1.0 to Flow. Once the upgrade is finished, you will be able to build with EVM on Flow and the latest version of Cadence on Testnet.

👉 If you had already staged your Testnet contract(s), they will be upgraded during the Testnet network maintenance time, and ready for you to use and experiment with when the Testnet is back online.

This upgrade marks a huge milestone on the road to bringing Crescendo to Mainnet. You can learn more about what this upgrade unlocks for developers via the article below ⤵️

We will inform you all when it has been completed.

Testnet will not be available until then.

Thank you,

Update
📣 The Testnet Crescendo Upgrade 📣

The Crescendo Network Upgrade is coming to Testnet!

We're excited to announce the finalized date for the next Testnet Crescendo Network Upgrade. Please note for all developers and node Operators that testnet will be down for roughly 6 hours during this upgrade, and all smart contracts must be staged before the upgrade for a seamless migration!

Flow Testnet will be upgrading on Wednesday, August 14, 2024 3:00 PM UTC (8:00 AM PT)

Flow Testnet will be unavailable between 8:00 AM to 2:00 PM on that day.

Please plan accordingly to the date and time of this Network Upgrade.

Note: If you don't upgrade in time for the Cadence 1.0 upgrade, your contracts and assets will be "bricked" and locked. With this upgrade, Cadence comes to a point of maturity, and will be backward compatible in future upgrades.

If you are using the FiatToken smart contract as a dependency, we will have more information on what you need to do soon.

Thank you,
