@benjamintshi How did you create such transaction?

[benjamintshi]

this is my code.

[benjamintshi]

i forked trezor-lib, because our network can not download "blake2b": "https://github.com/BitGo/blake2b#6268e6dd678661e0acc4359e9171b97eb1ebf8ac",

We are sunsetting this repository soon in favor of our monorepo. Can you please try the @trezor/utxo-lib package that is waiting in this PR if that code works for you? https://github.com/trezor/trezor-suite/pull/4421

trezor version : "@trezor/utxo-lib": "0.1.2",

The correct version from the monorepo should be 1.0.0, not 0.1.2. It seems you are still using the version from NPM, not from the monorepo.

[benjamintshi]

thanks, i'll try this version .

[benjamintshi]

1.0.0

npm got version 1.0.0-beta.9 1.0.0-beta.10 can not download

[prusnak]

npm got version 1.0.0-beta.9

Yes, 1.0.0-beta.9 is the correct one.

[benjamintshi]

npm got version 1.0.0-beta.9

Yes, 1.0.0-beta.9 is the correct one.

could you please give me some demo , I was confused how to use version 1.0.0 to build and sign a transaction offline , it has been changed.
