My coins are in trezor, hard to get the private keys out, is it possible to still provide a claiming service?
I am also wondering if there is some way around the Trezor problem.
Now that my BTC are locked down in Trezor, I am unwilling to move them.
You don't have to move them, just import your mnemonic seed on a wallet such as Electrum where you can export your private keys/sign message with an address.
