Package: eulith-trezor
eulith-trezorlibPython library and command-line client for communicating with Trezor
Hardware Wallet, modified to work more closely with Eulith clients & applications.Seehttps://trezor.ioandhttps://eulith.comfor more information.!! This is a derivative package of Trezor !!For the original package, please seehttps://github.com/trezor/trezor-firmwareThis package has been modified primarily to sort out dependency issues that come up when
trying to use the original trezor package with Ethereum tooling likeweb3py.InstallPython Trezor tools require Python 3.6 or higher, and libusb 1.0. The easiest
way to install it is withpip. The rest of this guide assumes you have
a workingpip; if not, you can refer tothis
guide.On a typical system, you already have all you need. Installtrezorwith:pip3installeulith-trezorOn Windows, you also need to either installTrezor Bridge, orlibusband the appropriatedrivers.Firmware version requirementsCurrent trezorlib version supports Trezor One version 1.8.0 and up, and Trezor T version
2.1.0 and up.For firmware versions below 1.8.0 and 2.1.0 respectively, the only supported operation
is "upgrade firmware".Trezor One with firmwareolder than 1.7.0and bootloaderolder than 1.6.0(including pre-2021 fresh-out-of-the-box units) will not be recognized, unless
you install HIDAPI support (see below).ChangelogAll notable changes to this project will be documented in this file.The format is based onKeep a Changelog,
