Electrum is an open-source lightweight desktop wallet for Windows, Linux, MacOS and Android OS. Linux users have to install Python tools, but there is no need to install these on Windows and MacOS systems.

It is also possible to connect Electrum wallet to your own full node using Electrum Personal Server. For more information, see this GitHub page.

ImportantPlease keep in mind that we do not develop nor maintain third-party software, so we cannot guarantee their full functionality. However, your private keys are always safely protected by your Trezor device, no matter what third-party application you use it with.

Recovering funds without Trezor device

In case your Trezor device gets lost or damaged, you can access your funds using your recovery seed and Electrum.

WarningThis should be used in emergency situations only. To keep your funds safe at all times, we recommend getting a new Trezor device to recover your funds (see Recovery) and not revealing your recovery seed to any third party. If you do decide to reveal your seed to a third party, send the funds to a new Trezor-secured account as soon as possible.

To recover your wallet in Electrum, follow these step:

1. Open Electrum and go to File > New/Restore.
2. Enter (any) name for your wallet.
3. Select "Standard Wallet".
4. Select "I already have a seed".
5. Enter your recovery seed. Separate the individual words using spaces (e.g. tree, all, hazard).
6. Click on Options and check "BIP39 Seed".
7. Unless you use a passphrase, do not check "Extend this seed with custom words". Click on Next.
8. If you used Trezor Wallet before, select p2sh-segwit (or legacy) account.
9. Set up a password or leave the fields empty.
10. Done.

NoteElectrum does not support multiple accounts per wallet. If you use multiple accounts, you need to import them individually. You need to change the derivation path for each account, e.g.:

• m/49'/0'/0' (first account)
• m/49'/0'/1' (second account)
• m/49'/0'/2' (third account)
