Overview
NUFI is a non-custodial multi-chain web wallet and browser extension that unifies balances, staking, NFTs, and DApp access across Cardano, Bitcoin, Solana, Ethereum, and a wide range of EVM and SVM networks behind a single interface1. Built by NUFI AG out of Baar, Switzerland, the wallet is developed by the team that previously created AdaLite, Cardano's first browser wallet, giving it unusually deep roots in the Cardano ecosystem2. It targets users who want one tool to manage assets across many chains without giving up self-custody.
Key Features
- Multi-chain coverage in one interface. Manages Bitcoin, Cardano, Solana, Flow, Tron, and the full EVM suite (Polygon, Arbitrum, Optimism, Base, Avalanche, BNB Smart Chain, and more) with integrated cross-chain swaps1.
- Broad hardware wallet support. Pairs with Ledger over USB and Bluetooth, Trezor, Keystone, OneKey, GridPlus, and BitBox, an unusually wide list for a web wallet3.
- Non-custodial social login. Wallets can be created with Google, Facebook, Discord, or X without a seed phrase using a key-splitting scheme that keeps private keys under user control1.
- Native Cardano staking. In-wallet ADA delegation with validator selection sits alongside native Solana and Flow staking, all routed through the same interface1.
- Cardano and Solana DEX integration. Direct in-wallet token swaps on both chains, plus DApp connectivity to major venues across the EVM and SVM ecosystems.
- MetaMask Cardano Wallet Snap. A dedicated Snap lets MetaMask users manage ADA and Cardano native assets through NUFI's integration2.
- Transaction screening via Blockaid. Each transaction is scanned for malicious addresses and phishing patterns before signing, in partnership with security provider Blockaid3.
What to Expect
The product is delivered as both a browser extension and a hosted web app, so onboarding can happen in a few clicks without installing desktop software. Users new to self-custody can start with the social login flow and graduate to hardware wallet pairing later, while existing Cardano users can import an AdaLite or seed-phrase wallet directly. The Cardano experience covers the basics most users need: ADA delegation, native asset and CNFT display, DEX swaps, and CIP-30 DApp connections. The interface emphasizes a unified portfolio view across chains rather than chain-specific dashboards, which suits users juggling assets across Cardano and EVM networks but means single-chain users may see UI elements they do not need. Documentation is hosted on a public GitBook for developers, and the codebase is available on the nufi-official GitHub organization for review4.
