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.

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.
