Introducing Our New Testnet Taiko Hoodi and Sunsetting Taiko Hekla

a day ago

Greetings developers,

We are pleased to announce the launch of our new testnet, Taiko Hoodi, which will now serve as the primary test environment for the Taiko ecosystem. At the same time, we will be sunsetting our long-standing Taiko Hekla testnet. Taiko Hekla was based on Ethereum’s Holesky testnet, which will also be deprecated at the end of September.

Hekla has been with us since before mainnet and has been instrumental in enabling developers across the ecosystem to test, refine, and ship products on Ethereum’s first based rollup, Taiko Alethia. We are grateful for the role Hekla has played and for the contributions of every developer who relied on it as a foundation for innovation.

As Taiko moves into a new era, with preconfirmations active and many more developments on the horizon, it has become clear that a new testnet is needed to support the protocol’s growth. That testnet is Taiko Hoodi, and it will now carry the network forward.

Key dates

September 25, 2025: Taiko Hoodi goes live
September 30, 2025: Taiko Hekla testnet deprecation and sunset

If you are currently building on Taiko Hekla, please migrate your work to Taiko Hoodi before September 30. If you hold testnet assets on Hekla, be sure to withdraw them ahead of the sunset.
