How to use the TAAS token with Ledger

The TaaS token (TAAS) is an Ethereum token (ERC20) supported by Ledger Nano S and Ledger Blue. While it is not yet compatible with the Ledger Wallet application, it can be managed using Ledger Nano S and Ledge Blue when connected with MyEtherWallet (MEW).

MEW is a popular online Ethereum wallet which can be used as an alternative to the Ledger Ethereum Chrome application. It supports the Ledger Nano S natively as well as the Ledger Blue on Chrome and Opera, without the need to install any application or plug-in.

Setting up

1 To manage your Ethereum account, go to the MyEtherWallet website (not the Chrome extension plugin) and select the “Send Ether & Tokens” tab. Connect your Ledger device to your computer, select the Ethereum app and go to “settings” in the app to activate “browser support.”

This will enable your Ledger to directly connect to the browser and MEW will be able to detect your device. (Note that if you wish to use the Ledger Ethereum Chrome application, you’ll have to disable browser support).

2 Select the “Ledger Wallet” option and click on “Connect your Ledger Wallet”.

3 A popup will appear where you’ll be able to select which HD derivation path and which address you want to manage.

4 Done! You can now send or receive transactions. Notice, that Ledger Wallet (Ethereum Chrome application) won’t display any TaaS tokens in your operations and balance.

To manage your tokens, you need to use your Ledger device with MyEtherWallet instead of the Ledger Wallet Ethereum Chrome application which won’t display any tokens.


To transfer TAAS stored anywhere else, just send it to one of the balance addresses you have selected. Notice that Ledger supports a maximum of five different currencies.


All outgoing transactions will require confirmation on the device (as with the Ledger Ethereum Chrome application). Only public data is sent to MEW, and your private keys will never be exposed to the browser.

Once you confirm the transaction on the device, please wait a few seconds for the signature to complete. It will then show the raw data on the web page, and you must click “Send transaction” again to display the final confirmation popup.

General information

Your tokens are not stored on the device itself; they are tracked on the Blockchain. Your Ledger hardware holds and protects the private data used to access and manage them. This data (private keys) is the certificate of the ownership of your tokens; it gives full access to these assets.

The 24-word seed phrase you copied to your Recovery Sheet when you initialize your device is paramount; it constitutes the backup passphrase to import access data to any wallet and give full access to your assets.

Without these 24 words and your PIN code, no one can access your wallet, even if your Ledger device gets stolen. Your secrets are securely stored inside the Secure Element of your device, and your assets are safe.
