Emilie Choi, President and Chief Operating Officer of Coinbase, stated that Coinbase is one of the first supporters of the "Trump Account" plan. Faryar Shirzad, Chief Policy Officer of Coinbase, mentioned that the company has submitted opinions to the Internal Revenue Service regarding the implementation and expansion of the account, suggesting that beneficiaries be allowed to invest in a wide range of traded digital assets or gain exposure to digital assets through funds, aligning the scope of qualified investments with the asset classes that traditional IRAs can invest in. Coinbase believes that broader and product-neutral rules will help expand choices, promote competition, and provide more opportunities for young people in the United States to engage in diversified investments and wealth accumulation. The qualified investments proposed by the Internal Revenue Service in the growth phase are currently mainly limited to tracking a broad stock index of U.S. companies, unleveraged mutual funds or ETFs with an annual fee rate not exceeding 0.1%.

Coinbase launches Bitcoin-collateralized fixed-rate, fixed-term USDC loans through Morpho Midnight, allowing borrowers to obtain USDC without selling their Bitcoin. The interest rate and repayment date for the product are determined at the start of the loan; if borrowers do not repay the USDC and interest before the due date, the collateralized Bitcoin may be reclaimed.The existing active or outstanding loan volume of Bitcoin-collateralized loans with floating rates supported by Morpho at Coinbase has exceeded 1.4 billion dollars, with collateral valued at approximately 3 billion dollars.

Aave V4 launched Equities Hub on Base, allowing eligible non-U.S. users to use seven U.S. stock tokens issued by Coinbase as collateral to borrow USDC, covering Apple, Amazon, Alphabet, Meta, Microsoft, Nvidia, and Tesla. The market is powered by Chainlink, providing on-chain price data for tokenized stocks. The initial collateral cap for the seven stocks is approximately $29 million, with a USDC supply cap of $32 million and a borrowing cap of $21 million. The collateralization rates for different stocks range from 65% to 79%.Currently, these stocks can only be used as collateral. Aave stated that more Coinbase tokenized stocks and GHO may be added as borrowable assets in the future after governance and risk assessments are approved.

Coinbase Chief Business Officer Shan Aggarwal published a post disclosing the integration progress after acquiring the cryptocurrency options trading platform Deribit, stating that the overall integration progress is "generally good." As of now, several advancements have been completed, including the launch of over 100 new USDC settlement contracts in 5 market areas, covering pre-IPO perpetual contracts, marking the largest expansion of perpetual contracts in Deribit's history.For the first time, stocks and ETFs are being traded in the form of perpetual contracts; a new matching engine has been launched to enhance the core trading infrastructure, making the large-scale trading environment faster and more stable while maintaining the user experience; and Deribit's spot trading has accessed Coinbase's spot liquidity. Shan Aggarwal added that the platform integration process still faces a lot of work, and more phased results will be announced in the future.

Vitalik Buterin, co-founder of Ethereum, delivered a keynote speech at the 12th Global Blockchain Summit, stating that the blockchain was initially a primary tool. Although it has characteristics such as openness, neutrality, and security, it is not scalable and is completely transparent, lacking privacy protection mechanisms.Subsequently, privacy transactions and scalable verification brought by zero-knowledge proofs have changed this situation and have been transformed from planning into actual EIPs, included in the Ethereum roadmap. Technologies such as fully homomorphic encryption are also beginning to be applied, and indistinguishable obfuscation may also be applied on-chain in the future. Beyond privacy, the parallel construction and proof of blocks can make extreme scalability possible, and industry thinking has shifted from digital assets to digital assets plus information, from purely on-chain to user-end, transaction memory pools, a complete pipeline on-chain, and from who can send what to who can see what.Currently, blockchain has gradually evolved from a simple ledger to a cryptography-based secure computing network. With the development of AI, providing cryptographic rules to AI for automated formal verification can significantly enhance verification efficiency, allowing the chain to carry more possibilities.

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.

According to official disclosures from Coinbase, it has collaborated with Microsoft and several institutions to combat the AI-driven cybercrime platform EvilTokens. This platform offers "phishing as a service" through Telegram bots, utilizing AI to analyze trust relationships and payment permissions in compromised email accounts, and bypassing multi-factor authentication through Microsoft's device code login process.The Coinbase global intelligence team tracked that between October 2025 and June 2026, EvilTokens generated approximately $1.1 million in revenue through four Tron addresses, involving over 1,000 deposits from more than 700 different addresses. The related evidence supported Microsoft's civil lawsuit, ultimately leading to the seizure of 50 websites and the deactivation of over 175 associated domain names. The Metropolitan Police Service of the United Kingdom arrested the relevant operators and seized digital devices on September 11. Coinbase stated that this incident did not result in the leakage of Coinbase accounts or credentials, but some customers were manipulated into transferring cryptocurrency to the scammers' addresses through phishing emails.

According to The Block, Coinbase announced the launch of fixed-rate Bitcoin collateralized loans through Morpho Midnight, allowing users to borrow USDC and determine the interest rate and repayment date at the time of borrowing. This new option is alongside Coinbase's existing floating-rate loans (based on Morpho Blue), which have outstanding loans exceeding $1.4 billion, corresponding to collateral of approximately $3 billion.Morpho launched Midnight on Base in July, introducing fixed rates and clear loan terms for on-chain lending. A Morpho spokesperson stated that Coinbase is the first mainstream consumer platform to offer Midnight loans on a large scale; since Midnight's launch, deposits have reached approximately $30 million. The outstanding loans for Morpho Blue across all integrations amount to $5.2 billion, with deposits reaching $16 billion.A Coinbase spokesperson did not disclose specific interest rates, stating that rates are determined by the supply and demand of both parties on the on-chain order book. Currently, Coinbase offers loans that mature at the end of the month or the end of the following month, and borrowers must repay before the due date; otherwise, lenders have the right to liquidate their collateral. Jacob Frantz, Coinbase's head of revenue and investment products, stated that Coinbase Borrow allows users to obtain liquidity without selling assets, and fixed-rate borrowing gives users greater choice in credit management. Morpho indicated that Midnight could also be used in the future to build structured credit products and loans collateralized by tokenized real-world assets, with more integrations in progress.
