SecondFi is the evolution of Yoroi Wallet — a self-custody neofinance platform with the tools to spend, stake, and secure your assets with full control of your assets.
A vulnerability in an earlier version of the wallet generation software affected a subset of Yoroi and SecondFi wallets. The SecondFi Wallet includes a built-in diagnostic tool to check your wallet and a guided migration process to move your assets to safety. Download the app and run the check immediately if you held funds in a Yoroi Wallet or SecondFi Wallet prior to June 2026.
Recovery Process
The SecondFi Wallet was built with the recovery process at its core. Every affected user has a clear, guided path to safety.
Open the SecondFi Wallet and run the built-in diagnostic scan. The tool cross-references your wallet addresses against the known vulnerability parameters without requiring you to expose your recovery phrase. Within seconds, you receive a clear verdict: unaffected, or flagged for migration.
If your wallet is flagged, the app walks you through a step-by-step migration. It generates a new cryptographically sound wallet, verifies its integrity, and then facilitates the transfer of all your ADA, native tokens, and NFTs to the new address — all without leaving the application.
Once your assets are secured, you are fully on SecondFi. Your staking delegation, DRep participation, and governance settings carry over automatically. The Yoroi brand continues as a DRep within the Cardano ecosystem, while SecondFi becomes your primary interface for all financial activity.
Built-In Capabilities
SecondFi is designed for Cardano users who take self-custody seriously. These are not add-ons — they are core to how the app works.
Connect your Ledger or Trezor device directly to SecondFi. Your private keys never touch the internet — all transaction signing happens on the hardware device itself, giving you the security of cold storage with the convenience of a full-featured desktop interface.
Before you sign anything, SecondFi analyzes the transaction against a continuously updated threat database. Malicious smart contracts, suspicious address patterns, and known phishing vectors are flagged before they can do harm — giving you a second line of defense beyond your own judgment.
Ask questions in plain language and get answers grounded in your actual wallet data. Whether you need help understanding a transaction, optimizing your staking delegation, or navigating the recovery process, the AI assistant is available directly within the app — no external tools required.
Yoroi Wallet to SecondFi
Yoroi Wallet was built by EMURGO, one of the three co-founding entities of the Cardano blockchain, and served over one million users as a trusted light wallet for ADA. In April 2026, EMURGO formally announced the evolution of Yoroi into SecondFi — a self-custody neofinance platform designed to go beyond simple storage and staking.
The transition preserves everything that made Yoroi reliable: open-source principles, non-custodial key management, and deep integration with the Cardano protocol. What SecondFi adds is scope — multichain support, card-based spending, expanded DeFi access, and the infrastructure to handle it all securely.
If you are a Yoroi Wallet user, run the diagnostic check now. If you are new to Cardano, this is where you start.
