NuFi wallet and OneKey: a potent combo for crypto users who want best-in-class hardware wallet security while staking, trading, and using dApps.

Here are five ways the NuFi x OneKey partnership is helping users achieve their crypto goals.
Safety first, safety last
Hardware wallets keep your private keys safe, but OneKey’s devices go further: they make transaction signing safe too. This is thanks to SignGuard, which eliminates the dangers of blind signing.
What is blind signing? Blind signing is when a transaction’s details can’t be displayed properly because a wallet can’t parse the details into human-readable text. The danger is obvious: you could be signing a malicious transaction that drains your wallet.
Enter OneKey’s SignGuard feature, which shows you exactly what you’re signing before you submit the transaction, including key details like the Method, Amount, Recipient/Approver, and Contract name.
NuFi helps here too. Like OneKey, NuFi uses Blockaid’s security stack to alert you if you’re using a suspicious dApp or interacting with a suspicious smart contract. Your OneKey wallet’s transactions and tokens are scanned by NuFi too, to keep you safe from spam tokens and address poisoning. More about NuFi’s wallet security here.

Do more (while your crypto stays secure)
A OneKey device keeps your crypto secure; NuFi wallet puts your crypto to work. Pair a OneKey device with NuFi and you can:
- Stake your OneKey wallet’s Solana and Cardano (to any validator) and earn crypto while you sleep
- Connect your OneKey wallet to DeFi and dApps on hundreds of chains
- Swap and bridge tokens on 185 chains, using three built-in Exchanges
- Manage NFTs (and trade NFTs on marketplaces)
While you’re using NuFi’s functionality, your crypto stays securely in your OneKey wallet at all times. Read more about NuFi’s features for OneKey users here.

NuFi’s integrations go deep
There’s nothing vanilla about NuFi’s multi-chain support. Whatever assets you manage in NuFi’s interface, you’ll have access to the latest features, from an exclusive RPC that boosts Solana transactions, to built-in DEXes that give you access to every Solana and Cardano token, to support for Bitcoin Ordinals and Runes, to Wallet Emulation that connects you to all dApps, to Smart Accounts on Ethereum, BNB and EVM, and much more besides.

Portable protection (that’s stylish too)
The OneKey Pro gives iPhone vibes – it’s lightweight, sturdy, stylish and secure, and features a large touchscreen and fingerprint biometrics (so only you can unlock it).
You can back up a OneKey wallet quickly and easily using the equally-slick OneKey Lite recovery phrase backup card: “Scan. Set PIN. Backed up. It's that easy.”
Support that won’t quit
Crypto’s not easy, and sometimes you need help. NuFi’s support team is always on-hand to advise you on all aspects of your crypto journey (and we guarantee a same-day response). Our support team is rated Excellent on Trustpilot; if you need anything, ask in Discord or open a support ticket here.
