Trezor Wallet for Ethereum & Altcoins

Trezor hardware wallets — including the Trezor Model One and Model T — are trusted tools for safely managing not only Bitcoin but also Ethereum and hundreds of altcoins. If you're an investor or user in the Ethereum ecosystem or exploring alternative cryptocurrencies, Trezor offers robust support with offline security and compatibility with decentralized applications.

1. Ethereum Support on Trezor

Trezor allows users to store, send, and receive ETH and all ERC-20 tokens. Ethereum support includes:

  • Hardware-based signing of Ethereum transactions
  • Display of transaction details (recipient address, amount, and gas fees) directly on the device screen
  • Secure token management via the Trezor Suite or third-party wallets

You can view and manage ETH and tokens using Trezor Suite, or pair your Trezor with external platforms like MetaMask, MyEtherWallet, or MyCrypto.

2. ERC-20 Token Compatibility

ERC-20 tokens like USDT, UNI, LINK, DAI, and SHIB are fully supported by Trezor. These tokens are held in your Ethereum address and can be managed through:

  • Trezor Suite (basic token support)
  • MetaMask or MyEtherWallet (for advanced features like staking or DApp use)

The private keys controlling these tokens remain secured by the Trezor device, meaning they never touch your computer or browser.

3. Altcoin Support

Trezor supports over 1,000 altcoins, including major coins like:

  • Litecoin (LTC)
  • Cardano (ADA)
  • Polygon (MATIC)
  • Binance Coin (BNB – BSC)
  • Solana (limited support via third-party tools)
  • Monero (Model T via third-party GUI)

Altcoin support varies by coin and wallet interface. Some assets are fully integrated into Trezor Suite, while others require compatible external wallets.

4. Connecting to MetaMask for Ethereum & Web3

To interact with DeFi, NFTs, or smart contracts, you can connect your Trezor to MetaMask:

  1. Install MetaMask and create a wallet
  2. Choose “Connect Hardware Wallet”
  3. Select “Trezor” and authorize the connection
  4. Confirm all transaction details on your Trezor before signing

This gives you full Ethereum/Web3 functionality with Trezor’s offline security.

5. Smart Contract & Gas Fee Safety

When sending ETH or interacting with a smart contract (e.g., Uniswap or OpenSea), Trezor:

  • Displays a contract warning if it detects complex or unknown calls
  • Allows you to review gas fees and destination addresses
  • Requires physical confirmation on the device before any transaction is sent

This feature prevents you from blindly signing malicious contracts or fake addresses.

6. Altcoin Tools and Interfaces

While Trezor Suite supports many coins, others may require third-party wallets, such as:

  • Exodus – for a clean interface with Trezor support
  • Electrum – for advanced Bitcoin and forked coin users
  • AdaLite – for Cardano (ADA)
  • Monero GUI – for Monero (XMR) with Trezor Model T

Always verify third-party apps are legitimate and compatible with your Trezor model.

7. Updates and New Coin Integration

Trezor frequently releases firmware and Trezor Suite updates to:

  • Add new tokens and altcoin support
  • Improve performance and user experience
  • Enhance security and compatibility with emerging Web3 technologies

Keeping your device updated ensures maximum compatibility and protection.

Final Thoughts

Trezor hardware wallets offer a powerful, secure way to manage Ethereum and altcoins. Whether you're trading ETH, holding DeFi tokens, or exploring altchains, your private keys stay safe inside your Trezor device — even while interacting with smart contracts or using Web3 apps.

With support for a wide range of coins and platforms, Trezor is a trusted choice for both beginners and advanced users in the altcoin ecosystem.
