How to choose the correct blockchain network when withdrawing from or sending to Trezor

When withdrawing crypto from an exchange to your Trezor device or sending crypto from it, you need to choose the correct network.

The correct network depends on the type of crypto you are withdrawing. Watch the video and follow the guidelines below to withdraw your funds to self-custody safely.

What is a blockchain network?

A blockchain network is the blockchain infrastructure used to send and receive crypto.

For example, tokens on the Ethereum blockchain can only be sent to addresses on the Ethereum blockchain.

Some blockchains are built on similar technology, such as EVM-compatible networks. This means that the same address format can be used across multiple networks.

As a result, relying on the address alone can be misleading, and sending funds over the wrong network can lead to loss of funds.

Networks supported by Trezor Suite

The following networks are supported natively within Trezor Suite:

Always make sure the selected network matches the network of the receive address.

Sending assets to a 0x address over the wrong network can result in permanent loss.

How do I identify which network I am using?

Choosing the right network to withdraw

Many exchanges offer multiple network options when withdrawing crypto. These alternative networks are often faster and cheaper, which is why they are commonly presented as withdrawal options.

Each exchange handles withdrawals differently, and the available options depend on the specific asset. Some assets exist on multiple blockchain networks, while others have migrated from one network to another over time. Because of this complexity, there is no single rule that applies to all blockchain assets and their relationship to blockchain networks.

Choosing the right network to send

When sending crypto from your Trezor device, you already control the assets on the blockchain, so you do not need to choose a network in the same way as when withdrawing from an exchange. However, it is still critical to make sure you are sending funds to the correct receive address and that the asset is supported by the destination.

In particular, be cautious with assets that have migrated from one blockchain network to another. If you hold tokens on an older network and send them to an exchange that only supports the newer network, the assets may not be credited to your account and could be permanently lost. In some cases, this can result in the assets remaining under the exchange’s control with no recovery option.

Because network migrations and token support are specific to individual projects and exchanges, Trezor cannot assist with issues unrelated to Trezor products or Trezor Suite. If you are unsure, check the project’s official documentation or contact the project team or community before sending funds.

Sending a test transaction

To make sure you selected the correct network, send a test transaction first. This applies to both sending and withdrawing assets.

When withdrawing assets from your Trezor device to an exchange, check the exchange’s minimum deposit before sending anything, as each exchange has its own rules. Once you know the minimum deposit, send that amount as a test transaction and wait for the assets to be credited to your exchange account. If the test transaction is successful, you can be confident the correct network is selected.

When sending assets from an exchange to your Trezor device, select the minimum amount allowed by the exchange and send that amount to your Trezor wallet to test out the transaction.

If you are sending assets between two wallets without using an exchange, you can send a very small amount to test the transfer. Blockchains do not enforce minimums, as long as you have enough to cover the transaction fee.

Once the assets appear in Trezor Suite, the exchange, or the receiving wallet, you can be confident that the network and receive address were selected correctly before sending a larger amount.
