Does Trezor Plan To Implement EIP2333 With A Firmware Update?

[adam-hurwitz]

Question — Are there plans from the Trezor team to support EIP2333 through a firmware update?

From the comments in Trezor and Ethereum 2.0 in r/TREZOR (3/29/21) a community member stated Trezor will not implement EIP2333 in the context of enabling a Trezor's seed to make withdrawals from a third-party Eth2 staking service, at least in the short-term.

Trezor needs to implement EIP2333 which it hasn't nor has any plans to…

Additional context The utility of EIP2333 is for hardware wallets to use their existing keys to interact with third-party Eth2 validator node services.

• Third-party Eth2 validator node services create the validator key.
• Hardware wallets create the withdrawal key from the third-party based on the wallet's existing seed.

In contrast, hardware wallets without EIP2333 would make the initial deposit to a third-party Eth2 validator service, and a brand new withdrawal seed will be created that the user will securely store and manage in addition to their original wallet's seed.

Correct. This is not on our immediate roadmap. However, if someone provides a good implementation of EIP2333, we will review it.

Thank you for the feedback @prusnak! "Someone" I estimate meaning an Eth2 third-party service provider implements EIP2333 appropriately?
