Brazil's central bank has implemented a new regulation that prohibits regulated electronic foreign exchange (eFX) providers from using stablecoins, Bitcoin, or other cryptocurrencies for settling cross-border payments. According to NS3.AI, Resolution No. 561, which was published on April 30, took effect on October 1. The regulation allows some firms until 2027 to either adapt to the new rules or seek authorization. The rule mandates that settlements must occur through a foreign exchange transaction or a non-resident real-denominated account in Brazil. While the regulation does not ban cryptocurrency trading, it effectively closes a payment channel previously utilized by companies such as Wise, Nomad, and Braza Bank.

Berkshire Hathaway reported a record cash and Treasury bill position of $397.4 billion in the first quarter of 2026. According to NS3.AI, this comes as Greg Abel maintains the company's anti-Bitcoin stance. The company's operating earnings increased by 18% to $11.35 billion during the quarter. Berkshire continued to be a net seller of equities, with no capital allocated to Bitcoin, spot Bitcoin ETFs, or any digital assets.

Arbitrum's Security Council seized 30,766 ETH from the KelpDAO hacker, valued at $71 million, but a US court order now prevents the DAO from accessing the funds. According to BeInCrypto, lawyers for North Korean kidnapping victims aim to claim the money under a 2015 judgment against Pyongyang. The legal action halts Aave and KelpDAO's plans to compensate users affected by the April 18 hack. The freeze highlights how centralized governance actions can lead to assets being pulled into US courts. The Southern District of New York issued the order, barring Arbitrum from transferring the seized assets.

Developers Sergio Lerner and Dan Held have expressed concerns regarding Paul Sztorc's proposed eCash fork, suggesting it resembles an airdrop to Bitcoin holders rather than a traditional Bitcoin hard fork. According to NS3.AI, the developers highlighted that the UTXO-based distribution method and absence of comprehensive replay protection might pose operational challenges and potential fund-loss risks for users attempting to claim the tokens.

Japan has reportedly intervened in the currency market by purchasing approximately $35 billion worth of yen, causing the dollar to decline nearly 3% to 155.5. According to NS3.AI, data from the Bank of Japan (BOJ) suggests this scale of intervention, and confirmation from the Ministry of Finance would mark Japan's first official action to support the yen in almost two years, making it the second-largest intervention on record. The short-rate gap between the BOJ and the U.S. Federal Reserve remains around 275–300 basis points, which is a key factor driving yen-funded carry trades.

Polymarket's monthly fees reached an unprecedented $43.36 million in April, according to DeFiOasis data. This figure represents more than a twofold increase from the previous month.

Together, these two markets accounted for over 97% of the fees in the on-chain prediction market.

Gen Z individuals are facing an average personal debt of $94,101, according to economist Alice Lassman. She describes this trend as part of a broader economic shift she terms 'disillusionomics,' where young adults are increasingly building multiple income streams to navigate an uncertain financial future. According to NS3.AI, this shift is characterized by a declining belief in homeownership, a focus on value-driven spending, and a growing reliance on buy-now-pay-later services.

On May 2, Huang Licheng, also known as 'Machi Big Brother,' significantly increased his Ethereum (ETH) position using 25x leverage, bringing the total to over $30 million. According to BlockBeats On-chain Detection, the opening price for this position was $2,311, with a liquidation price of $2,229. Additionally, Huang holds a Bitcoin (BTC) position with 40x leverage, valued at $28.5 million. The average opening price for this position is $77,156, with a liquidation price of $75,654.

The Ethereum Foundation recently hosted the 'Soldøgn Interop' event from April 28 to May 2 in Longyearbyen, Svalbard, Norway, gathering over 100 core developers for a week-long focus on the Glamsterdam network upgrade. According to Foresight News, the event achieved three main objectives. Firstly, the stable operation of ePBS (enshrined PBS) across multiple clients was confirmed, with the external Builder process completing end-to-end testing and glamsterdam-devnet-2 going live. Secondly, the EIP-8037 proposal for adjusting state creation gas fees finalized its parameters, shifting from dynamic pricing to a fixed cost_per_state_byte, stabilizing in bal-devnet-6. Thirdly, developers set a target minimum gas limit of 200 million for the Glamsterdam upgrade, following improvements in execution layer throughput from block-level access list (BAL) optimizations and structural adjustments in block timing by ePBS. The final gas limit parameters and fee adjustments will be confirmed and announced in an upcoming AllCoreDevs meeting. Additionally, progress was made on the Hegotá upgrade, with FOCIL completing an early prototype and advancing multi-client testing. The native account abstraction (AA) proposal addressed key requirements such as signature replacement, aggregation, gas sponsorship, and L2 DoS resistance. CL developers also made final decisions on EIPs within the Glamsterdam scope, including EIP-8061 and EIP-8045, while postponing EIP-8237 to a future fork.
