ViaBTC founder and CEO Yang Haibo stated: CoinEx is shutting down, but its hot wallet system is still relatively advanced and worth referencing in the industry. He introduced that CoinEx has implemented an MPC-based dual-signature scheme for its hot wallet to eliminate single points of failure.Yang Haibo mentioned that the relevant infrastructure is split into business systems and wallet systems, operated by completely independent teams, each holding one private key. Every withdrawal or transfer must be reviewed in real-time through substantial risk control by both parties, and even if one system is compromised, assets cannot be stolen.He added that the wallet signing process needs to be independently implemented and cannot rely on the native mechanisms of each node, which requires extensive reconstruction. The team spent over a year transforming the vast majority of nearly 300 chains supported by CoinEx one by one.

Coinbase Chief Cryptographer Yehuda Lindell stated on the MARA Foundation TV program that the exchange is designing a custody system capable of adapting to any post-quantum signature scheme that Bitcoin may adopt in the future. It is currently unclear which post-quantum signature scheme Bitcoin will use in practical applications. Lindell believes it is unlikely that a single signature scheme will be universally adopted, so preparations must be made for different outcomes across various blockchains.Coinbase is custodian for approximately $250 billion in assets for institutions such as BlackRock. Traditional Multi-Party Computation (MPC) relies on key sharding, but many post-quantum signature schemes may be "not friendly to MPC"; for example, hash-based signatures lack the arithmetic structure required for traditional cryptographic key splitting. Although cryptographers like Dan Boneh are researching relevant solutions, this research is still in a highly experimental phase, and it remains uncertain whether a viable MPC-like solution for hash signatures can be developed.To this end, Coinbase is exploring a backup architecture centered around programmable Hardware Security Modules (HSM), where private keys will be encrypted with post-quantum cryptography and assembled only within physically secure HSMs. Lindell stated that while the completion timeline is uncertain, once finished, "I will be able to say, I can support any scheme," without worrying about a blockchain adopting a signature scheme that it cannot support.

realtrumpcoins issued a statement claiming that the news regarding the launch, promotion, or authorization of Trump Coins to issue digital tokens is "completely false," and the related information is a malicious act by a third party.The statement emphasized that Trump Coins has never authorized any digital tokens and will not launch, promote, or authorize any digital tokens in the future. Currently, it is cooperating with relevant law enforcement agencies to investigate this matter and seek accountability from those involved.Earlier reports indicated that the meme coin GOLD was created on Solana yesterday at 7:38, with the related address controlling over 82% of the tokens through token distribution and purchases after the launch. Around 9 o'clock, the merchandise collaboration account @realtrumpcoins1 tweeted containing the GOLD contract address, causing the token's market value to briefly surge to $66 million.Around 11:48, the tweet was deleted, and the related address immediately began to sell off its holdings. The market value of GOLD plummeted from $55 million to $1 million in about 30 seconds, after which the scam operators continued to sell off their tokens, ultimately selling all their holdings and accumulating a profit of approximately 9784.6 SOL (about $1.01 million).

Binance co-founder He Yi stated that Binance Wallet currently accounts for about 75% of the overall wallet transaction volume, processing over $13 billion in transactions daily. The wallet uses a Multi-Party Computation (MPC) architecture to enhance asset security and account recovery capabilities, and integrates features such as error address protection, potential malicious contract warnings, and high-risk token/network alerts.He Yi mentioned that the future direction of self-custody development is not only to improve security strength but also to make security usage more intuitive at the product design level.

Sui posted on platform X, stating that institutions will not choose to settle on infrastructure where competitors can see pricing and trading volume. The public amounts on most blockchains have been a barrier to actual commercial settlements.Mysten launched a new prototype that addresses the issue of amount privacy. This prototype is built on Seal MPC and confidential transfers.

According to GoPlus monitoring, the hacker group TeamPCP claims to have obtained the source code from about 4,000 private repositories within GitHub and is selling it for $50,000 on underground forums, offering sample verification. If no one buys it, this batch of data may be publicly released for free later.Previously, GitHub officials confirmed that they are investigating the issue of "unauthorized access to internal repositories," suspecting that malicious VS Code/AI Coding plugins were installed on GitHub employee devices.

Cactus Custody announced that its self-custody MPC (Multi-Party Computation) solution is officially launched. As a custody brand under Matrixport, Cactus holds a Hong Kong Trust TCSP license and has served numerous industry-renowned clients such as RedotPay, Fosun Wealth Holdings, and TDTC.As the Web3 industry matures, institutional clients are increasingly inclined to gain autonomy in custody while demanding the robust security infrastructure provided by third-party custodians. Cactus Custody's MPC solution cleverly bridges this gap by combining cutting-edge Intel SGX TEE (Trusted Execution Environment) with an institution-centric risk management engine.The core security cornerstone of the platform is the advanced MPC-TSS (Threshold Signature Scheme). Through this technology, private key shards are independently generated by multiple parties and jointly managed by devices controlled by Cactus and the clients. This architecture effectively eliminates the risk of "single points of failure," ensuring that no party can unilaterally transfer funds, thereby providing clients with absolute asset sovereignty and peace of mind.Cactus Custody CEO Daniel Lee commented, "Our new MPC solution is designed for institutions that prefer to manage assets directly while requiring secure and compliant infrastructure. By providing a compliant, flexible, and secure platform, we empower clients to flexibly and fully autonomously scale their digital asset businesses."
