Ethereum Hoodi Testnet

In support of the Ethereum Pectra upgrade, BitGo migrates from using the Ethereum Holesky testnet to the Hoodi testnet. The testnet ticker symbol on the BitGo platform continues to be hteth.

Breaking Changes

BitGo disables support for the Ethereum Holesky testnet. All your existing Ethereum wallets on the Holesky testnet no longer function. BitGo did the following:

• Disabled use of Holesky wallets on the BitGo platform.
• Reset the nonce of the fee address. Fee addresses now have 0 transactions.
• Cleared the send queue for 'hteth'.
• Rejected all the unresolved pending approvals.

To migrate to Hoodi and resume your testnet activities:

1. Create Hoodi wallets (see Wallets Overview).
2. Obtain new hteth from an Ethereum Hoodi Faucet. Your Holesky hteth isn't transferable to Hoodi wallets.
3. Update all instances of Holesky wallets in your integration to use newly created Hoodi wallets.
