I sent some ERC20 token to an ethereum address in my trezor and I can successfully see it using MEW. I wish to use this as an air-gapped wallet but with frequent use (i.e, not cold wallet).
Suppose I create a raw transaction, how do I call trezorconnect to sign it?
[Edit: The method might be to call signtx in trezor and have crypto elements v,r,s returned and then somehow convert to format ready for broadcast. If correct, code please?]
