Upcoming Changes to Ethereum Testnet in Nodit

Dear Users,

Following Ethereum's "Pectra" upgrade, the Foundation introduced the Hoodi testnet (live as of March 18, 2025) and plans to sunset Holesky in September 2025. Nodit will align our network support accordingly―please note that Holesky deprecation is confirmed for the end of May 2025, while Hoodi support is still being finalized. We will announce the exact dates for Hoodi as soon as they're set.


1. What's changing?

Hoodi Testnet

  • Live as of March 18, 2025
  • Ethereum Foundation’s recommended post‑Pectra test network
  • Nodit will support Hoodi in the coming weeks (exact date TBA)

Holesky Testnet

  • Scheduled for sunset by Ethereum Foundation in September 2025
  • Nodit will deprecated Holesky support on May 31, 2025.

2. What you need to do

If you're currently using Holesky:

  • Plan to migrate off Holesky before May 31, 2025.
  • Change the {network} segment in your API URLs to sepolia(available now) or hoodi(coming soon).
    • Node API: https://ethereum-{network}.nodit.io/
    • Web3 Data API: https://web3.nodit.io/v1/ethereum/{network}/…

To prepare for Hoodi support:

  • Keep your configurations ready to switch {network} to hoodi once we confirm and publish the Hoodi endpoints.
