: Cardano ecosystem wallet project SecondFi has announced the launch of a wallet migration tool and revealed a recovery plan for assets affected by the June 2026 security incident. As the project will cease operations, users are required to migrate remaining assets still held in SecondFi wallets. The migration tool is expected to go live on August 13, supporting the transfer of eligible ADA, Cardano native tokens, and NFTs to new Cardano wallets created with service providers of the users' choosing. Currently, the tool only supports Cardano network assets; non-Cardano assets must be transferred separately through corresponding network and wallet processes. SecondFi stated that the migration tool has passed an independent security assessment by security firm Bitdefender. For affected assets, SecondFi plans to launch a recovery portal before September 10, where users can verify wallet ownership via zero-knowledge proofs (ZK Proof) and submit asset claims. SecondFi reminds users to only rely on information published through official channels, including @secondfiapp, @secondfi_jp, and the official support website, to guard against phishing sites and impersonating accounts.
Odaily News: The U.S. Internal Revenue Service (IRS) issued a fraud alert on July 30, warning that scammers are mailing counterfeit IRS notices requiring cryptocurrency holders to register through a non-existent "Digital Asset Compliance Portal" before an urgent deadline. Each fraudulent letter contains a QR code that directs recipients to a website impersonating IRS.gov. The fake portal may request personal information, cryptocurrency wallet details, exchange login credentials, recovery phrases, private keys, or other data that could be used for theft. Cryptocurrency exchange Coinbase and cybersecurity firm Darktower traced the related infrastructure to a domain registered through a Hong Kong-based registrar shortly before the letters were distributed. Investigators found that the website is hosted in Romania, on a network previously associated with phishing pages impersonating financial institutions.

According to official information, Mantle announced today that its native cross-chain infrastructure Mantle Super Portal, jointly developed with Bybit, has migrated from LayerZero to Chainlink CCIP. Powered by CCIP, Mantle Super Portal will feature enhanced cross-chain security, decentralized node infrastructure protection, advanced risk management, and institutional-grade security standards, providing a higher level of security for cross-chain transfers of MNT tokens valued at over $2.5 billion. Furthermore, as an increasing number of regulated assets such as tokenized stocks are transferred on-chain, the underlying infrastructure supporting them must also meet traditional finance standards. This migration will further solidify Mantle's position as a "distribution layer connecting traditional finance and on-chain liquidity," and also reflects Mantle and Bybit's continued commitment to developing MNT through further integrations, opportunities, and use cases. According to the details provided, Mantle Super Portal will be temporarily closed during the migration, scheduled from July 9 to 15, 2026 (the actual timeframe may be slightly extended). No action is required from users, and transfers will automatically resume upon completion of the migration.

Polygon has officially launched its native liquid staking token, sPOL, designed to enhance returns for POL token stakers. As Polygon’s native liquid staking token, sPOL unlocks approximately 3.6 billion staked POL tokens and grants stakers priority access to transaction fee revenue sharing. Currently, only about 4%–5% of POL is liquid; sPOL addresses the issue of idle capital being unable to participate in DeFi yield opportunities. Users can migrate existing stakes to sPOL via the Polygon Staking Portal—without waiting periods and with uninterrupted rewards—while new stakes will automatically receive sPOL. The initial sPOL redemption ratio is 1:1, increasing as staking rewards accrue. sPOL supports liquidity provision, collateralization, and yield-boosting DeFi strategies, and can be redeemed at any time for POL plus accumulated rewards. The token was initially launched by Polygon Labs and audited by ChainSecurity and Certora; official liquidity will be seeded through an on-chain liquidity pool. Polygon cautions that sPOL carries smart contract risk, validator misbehavior penalty risk, and market volatility risk.
