Many Solana Dapps don't support Trezor directly. NUFI acts as a go-between: pair your Trezor's Solana accounts with NUFI, then connect to Dapps through NUFI while your keys stay on the device. This works with the Trezor Model T, Safe 3, Safe 5 and Safe 7.


When you connect, the Dapp only sees your public address, so it can show your balances and activity. Your private keys and personal information are never shared, and every transaction must be approved on your Trezor.


1. Pair your Trezor with NUFI

If you haven't already, pair your Trezor's Solana accounts with NUFI.


2. Connect to a Dapp

With NUFI browser extension (recommended)

  1. Open the Dapp and click Connect wallet.
  2. Select NUFI. If NUFI isn't listed, use Wallet Emulation.
  3. In the NUFI window, choose your wallet profile, if you have more than one, and your Trezor Solana account.


With NUFI web wallet (using WalletConnect)

  1. Open the Dapp, click Connect wallet, then choose WalletConnect.
  2. Either:
    • Copy the link from the WalletConnect popup, open wallet.nu.fi, click Wallet Connect in the left-hand sidebar, paste the link and click Connect; or
    • click Desktop at the bottom of the WalletConnect popup and search for NUFI.
  3. Choose your wallet profile and Trezor Solana account.


Wallet Emulation: when a Dapp doesn't list NUFI

NUFI's browser extension can connect in place of Phantom:

  1. Open your browser's extension settings (Extensions → Manage extensions) and switch Phantom off. This only disables it; you can turn it back on later.
  2. Reload the Dapp page.
  3. Click Connect wallet, choose Phantom, and NUFI opens instead.


Troubleshooting

  • I chose Phantom but NUFI didn't open: the browser is still trying to load Phantom. Make sure it's disabled, then reload every open page of the Dapp (F5).
  • The Dapp asks me to "sign a message" and it fails: some Dapps ask you to sign a message to prove you own the wallet, and Trezor doesn't support this for Solana. For those Dapps, use a NUFI hot wallet Solana account instead, moving funds between your Trezor and hot wallet accounts in NUFI as needed.
