Ethereum Core Developers Create New Testnet Hooli to Demonstrate Pectra Upgrade

Following two problematic tests of Ethereum's upcoming Pectra upgrade, the network's core developers decided to create a new testnet

The Ethereum core developers have decided to create a new testnet to demonstrate the code update a final time before deployment, following two problematic tests of Pectra, the network's upcoming upgrade.

Pectra will be tested on the new testnet, Hooli, which is set to launch on Monday, March 25, according to Tim Beiko, who coordinates the ecosystem's core developers at the Ethereum Foundation.

Pectra will be tested on Hooli on Wednesday, March 26, when the test chain will be upgraded to the new version of Ethereum and evaluated for performance and stability.

If the Hooli test succeeds, Beiko said developers will launch the upgrade after approximately 30 days, subject to further testing. Should everything proceed as planned, Ethereum users can expect Pectra to reach the ecosystem's main network in late April or early May.

Hooli will be created following complications with Pectra tests on Sepolia and Holesky, Ethereum's primary test networks. In both instances, configuration errors prevented proper testing of the Pectra upgrade. In Holesky's case, the network was offline for multiple weeks due to the flawed test issues.

Test networks like Holesky, Sepolia, and Hooli function almost identically to the main Ethereum network but are generally free to use and not intended to support real value. Major upgrades like Pectra are typically implemented on Ethereum's test networks before full deployment on the mainnet, as any disruptions on the actual Ethereum network could be extremely costly.

According to Beiko, Sepolia and Holesky — which are now running Pectra successfully — serve different testing purposes. "If you need to test validator exits, be on the lookout for [Hooli]! Everything else can be tested on Sepolia & Holesky," Beiko stated in his Thursday post on X.

Pectra's technical setbacks come during a challenging period for Ethereum. The network has faced mounting pressure from declining ETH prices, leadership transitions at the Ethereum Foundation, and growing skepticism about its ability to maintain market dominance amid competition from newer blockchains like Solana. Industry figures view the successful implementation of Pectra as crucial for restoring confidence in Ethereum's technical roadmap.
