In addition to Trezor Suite, you can use your Trezor device with an increasing number of independent cryptocurrency wallets and online services.
We believe that Trezor Suite is the best solution to manage your crypto assets, but there are some reasons you might choose to use your Trezor with a third-party wallet.
Some third-party wallet interfaces let you connect your Trezor device and work with it. They do not hold any private keys. Instead, they display account balances and help you to manage transactions.
First, your Trezor contains a seed, 12 or 24 words that generate all the keys and addresses associated with your assets. That seed never leaves your device: when a transaction needs to be signed, the transaction data is sent into your Trezor, signed offline, and then passed back out.
Using a third-party app, the exact same thing happens, but rather than Trezor Suite preparing the message data, the third-party app sends the message to your Trezor device. Since the Trezor can only accept a specific format, you don’t need to worry too much about which apps or extensions you connect to, as long as you use your Trezor to ensure that the transaction recipient address, amounts, and fees, are correct.
This is where Trezor’s Trusted Display comes in — your Trezor screen will only ever show you the data that will be signed, so if a malicious attacker swaps the address for one of their own, or alters the amounts being sent, your Trezor will let you see that the data is not what you set so you can cancel the transaction.
While there are quite a lot of supported cryptocurrencies that are supported in Trezor Suite and by the Trezor firmware, it is important to note that many of these are only supported via third-party applications. Let's take a look an example using our supported coins page.
We can see from the information on our supported coins page that while Polygon is supported via Trezor Firmware, it's mainnet is only supported via a third-party application such as MyCrypto or MyEtherWallet.
