Requiring PSBT for Cold Wallets

BitGo now requires using the Partially Signed Bitcoin (PSBT) transaction format for withdrawals of UTXO assets from cold wallets in production. This requirement applies to custody wallets and self-custody cold wallets. This change already took effect in testnet on September 2, 2025.

Breaking Change

  1. You must update to a newer version of the OVC. You must also update to a newer version of either BitGo Express or the SDK (depending on your integration).

    Ensure you're using the follow versions or higher:

  2. Ensure that when you initiate transactions, the value for the txFormat parameter is psbt or psbt-lite (if you don't pass this parameter, the value defaults to psbt-lite). If txFormat is legacy, BitGo returns an error.

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.
