First of all, thanks for building these devices that are essential to anyone keeping the custody of their Bitcoins.
Today I have 3 questions for you, all related to "Multisig".
For organizations, relying on a hardware wallet is not practical and also has its security implication (most of them related to access-control). Multisig is a good solution for this problem, offers great flexibility and extra security. Having the ability to use Multisig together with hardware wallets would be perfect.
So the questions are:
  • What is the status of the multisig support for Bitcoin in Trezor?
  • What is the status of the multisig support for other supported currencies?
  • What about cryptocurrencies/networks that don't have native support for Multisig and rely on MPC to achieve the same goal? Will any of these be supported by Trezor?
It is possible to use multisignature transactions with your Trezor device and Electrum and other popular multisig wallets, however it is not yet implemented in Trezor Suite. There are no specific plans for multisig implementation in Trezor Suite.
Here is our co-founder @stick showing demo of the multisig usage with Trezor and Electrum Wallet:

Altough Trezor Suite does not support multisig natively, Bitcoin multisig is the first class citizen in Trezor. You can sign multisig transactions on Trezor with almost any wallet that supports both (multisig and Trezor), such as Bitcoin Core, Electrum, Sparrow, etc.
