Andre Cronje stated in an interview with Cointelegraph that many DeFi protocols today are "no longer truly DeFi" and are more like "profit-driven companies operated by teams," as they generally rely on upgradable contracts, multi-signatures, off-chain infrastructure, and manual operational control.Cronje pointed out that the current industry is still overly focused on smart contract audits while neglecting operational risks that are closer to traditional finance (TradFi). He believes that recent attack incidents are not due to code vulnerabilities but stem from off-chain infrastructure, permission management, and social engineering attacks.The discussion arises from the recent frequent security incidents in DeFi. In April, protocols such as Flying Tulip, Drift Protocol, and Kelp encountered security events, with Drift and Kelp suffering losses of approximately $280 million and $293 million, respectively.In response, Flying Tulip has introduced a "Withdrawal Circuit Breaker," which can delay or queue withdrawal requests when unusually large withdrawals occur, allowing the team about 6 hours to respond. Cronje emphasized that this mechanism does not permanently freeze withdrawals but serves as a layer of protection within the security system.However, Michael Egorov holds a cautious attitude towards this. He stated that the circuit breaker itself could also become a new point of centralized risk. If control permissions fall into the hands of an attacker, the mechanism originally intended to protect the protocol could instead be used to freeze assets or directly transfer funds.Egorov believes that the long-term direction of DeFi should be to minimize human intervention and centralized permissions as much as possible, rather than adding more layers of manual control. "The security of DeFi comes from decentralization, not more human management."

According to CBC News, the Canadian federal government has announced plans to completely ban cryptocurrency ATMs to protect the public from fraudsters.This move was formally proposed in the government's spring economic update, which characterizes cryptocurrency ATMs as "a major means for fraudsters to deceive victims and for criminals to launder money." Cryptocurrency ATMs allow users to deposit cash and exchange it for cryptocurrencies like Bitcoin, which can then be transferred to any virtual wallet globally. A previous investigative report by CBC News titled "Feeding Fraud" revealed that such machines have become a primary channel for fraudsters to obtain victims' funds in Canada. The Canadian financial intelligence agency FINTRAC also reached the same conclusion in its analysis report in February 2023.Currently, Canada has the highest number of cryptocurrency ATMs per capita in the world, with nearly 4,000 machines nationwide, but there is still a lack of specific regulatory laws for the industry. The government stated that after the ban is implemented, the public can still purchase virtual currencies through physical currency service providers.

The Solana Foundation stated that its core development team Anza has reached an agreement with Firedancer, a subsidiary of Jump Crypto, on a potential post-quantum solution, planning to introduce a new digital signature scheme called Falcon.Although the threat of quantum computing is not expected to materialize for several years, Solana has developed a phased upgrade roadmap. This plan includes ongoing research into Falcon and other alternatives, introducing post-quantum solutions for new wallets when necessary, and ultimately completing the migration of existing wallets. Currently, the quantum-resistant primitive Winternitz Vault, developed by Blueshift, has been running on Solana for over two years. The Solana Foundation stated that the network's high-speed, low-latency design can accommodate such solutions, and the migration is not expected to have a significant impact on performance.

According to monitoring by Bubblemaps, about 50% of the BULL tokens are in a highly concentrated state, hidden within a complex matrix of associated wallets. A cluster of over 100 wallets has transferred some tokens to new wallets and is selling them in small batches to evade monitoring, currently making a profit of about $250,000, with multiple addresses selling at the peak. This cluster still holds 30% of the total supply of BULL.

MonetSupply, the strategy director at Spark, posted on platform X that Aave has decided to lift the freeze on the Ethereum Core WETH market. Under the current interest rate model, LST/LRT holders can execute high-leverage circular strategies using assets like weETH, taking advantage of the approximately 0.5% discount on the weETH market price and the Aave ETH borrowing rate cap of 5.15%, to achieve an annualized return potential of about 45%.Currently, the utilization rate of the aEthWETH market has reached 100%, making it more difficult for regular depositors and stablecoin borrowing users to exit or refinance from aWETH. MonetSupply pointed out that this decision provides arbitrage opportunities without addressing the liquidity tension of aEthWETH, weakening the liquidity and experience for regular users.

According to Jinshi reports, U.S. President Trump stated that he has always supported interest rate hikes to combat inflation and mentioned that the effect of interest rate hikes in suppressing inflation has been quite good.

According to The Block, the x402 Foundation, incubated by Coinbase, has announced the launch of the unified platform Agent.market, aimed at providing an "app store"-like service entry for AI robots.The platform is built on the x402 protocol and helps users and robots access hundreds of tools and services. The x402 protocol is named after the unused HTTP 402 "Payment Required" status code, allowing websites, APIs, and AI robots to request and receive instant micropayments through blockchain and traditional payment channels. The protocol is managed as an open standard by the x402 Foundation under the Linux Foundation and has the support of over 20 organizations and crypto companies, including Cloudflare, Stripe, AWS, Google, Visa, Base, Circle, and the Solana Foundation.When Agent.market goes live, it will cover seven major categories including reasoning, data, media, search, social, infrastructure, and trading, with service providers including OpenAI and Venice (reasoning); Bloomberg and CoinGecko (data); LinkedIn, X, and AgentMail (social); AWS Lambda, QuickNode, and Alechemy (infrastructure); as well as Bankr and Coinbase RAT (trading). Providers can join the marketplace without permission.Erik Reppel, the creator of the x402 protocol, stated that there are currently about 69,000 active agent robots on the protocol, which have completed over 165 million transactions with a transaction volume of 50 million dollars. He pointed out that agent commerce based on x402 is reshaping the customer acquisition activation costs for businesses, as robots can now access services at a very low setup cost without needing API keys.

One of the Bitcoin contributors, Jameson Loop, along with other cryptographers, has proposed an initiative that may force Bitcoin holders to migrate their tokens to new quantum-resistant addresses, or else their tokens will be permanently frozen by the network itself. In this scenario, holders technically still own these coins but will lose the ability to transfer them. This is known as Bitcoin Improvement Proposal BIP-361, which was updated on Tuesday in Bitcoin's official proposal repository, titled "Post-Quantum Migration and Old Signature Retirement."BIP-361 builds on the BIP-360 proposal introduced in February. BIP-360 introduced a soft fork (a type of network upgrade) aimed at enabling a new transaction type called "Pay to Merkle Root" (P2MR). This approach draws on Bitcoin's Taproot (P2TR) framework but removes key-based spending paths, thereby eliminating an element widely considered to pose risks in the quantum era.The BIP-361 proposal divides the migration into three phases. Phase A starts three years after activation and prohibits anyone from sending new bitcoins to old, quantum-vulnerable addresses. You can still spend from these addresses, but you cannot receive any coins. Phase B starts five years after activation and will render old signatures (ECDSA and Schnorr) completely ineffective, with the network rejecting any attempts to spend coins from quantum-vulnerable wallets.Essentially, your coins will be frozen. Finally, there is Phase C, which is a rescue plan still under research: holders of frozen wallets may potentially prove ownership through zero-knowledge proofs (a method of proving knowledge of a secret without revealing the secret itself). If successful, the coins frozen in Phase B can be recovered.
