Ethereum's Glamsterdam upgrade will adjust gas pricing for state operations, and a small number of contracts with hardcoded gas assumptions may need to be fixed.

The Ethereum Foundation team has released an impact assessment of gas repricing for the upcoming Glamsterdam upgrade. The upgrade includes two EIPs: EIP-8037 and EIP-8038. The former increases and standardizes the cost of creating new states, including new accounts, new storage slots, and deployed bytecode. The latter raises the cost of state access operations (such as SSTORE, SLOAD, and cold account access), making gas prices more accurately reflect actual resource consumption. State operation gas pricing has not been adjusted since the Berlin fork in 2021, while Ethereum’s state size has grown significantly, and recent increases in the gas limit have further accelerated this growth. The new pricing is based on a performance target supporting approximately a 3x increase in base throughput, and serves as a necessary prerequisite for future further hikes in the gas limit. The team evaluated the actual impact by replaying historical mainnet transactions, categorizing all transactions into four groups: most transactions are completely unaffected; some transactions still succeed but have changes in details like gas usage; some contracts run out of gas under their original limit but can complete when the limit is raised; a tiny number of contracts may still fail even with a significantly increased gas limit. This last category typically relies on hardcoded gas assumptions. Developers can check if their contracts are affected and verify fixes on the Plat?berget testnet. End users do not need to take any action, as updated wallets and infrastructure will handle the changes automatically.

Ethereum Foundation Warns: Glamsterdam Upgrade May Cause Some Wallets and Tools to Stop Working

The Ethereum Foundation (EF) has warned developers that upcoming gas model changes in the Glamsterdam upgrade may cause compatibility issues for some wallets, indexers, and gas estimation tools. The EF’s Protocol Development and Operations team stated that any tools relying on hard-coded maximum gas limits will be affected and require updates. The team advised developers to test relevant systems in advance on the Plataberget public testnet, which will run for several months to prepare for the Glamsterdam upgrade. According to upgrade tracking platform Forkcast, Plataberget launched on August 13, and the Glamsterdam fork is scheduled to activate on the network this Thursday, followed by deployments on the Sepolia and Hoodi testnets. This upgrade involves EIP-8037, which introduces an independent "state gas" dimension for operations that create new blockchain states. Post-upgrade, standard ETH transfers to existing accounts will still require 21,000 gas, but sending ETH to new accounts will incur additional state gas fees. The Ethereum Foundation noted that developers need to re-audit software that defaults to "all ETH transfers only cost 21,000 gas" or uses a single gas dimension to estimate transaction costs. In addition to gas model adjustments, Glamsterdam will also include native Proposer-Builder Separation (PBS), block-level access lists, and improvements such as increasing size limits for contracts and initialization code.

Cboe applies to the SEC for approval of the first U.S. 3x leveraged Bitcoin and Ethereum ETFs.

The Cboe BZX Exchange, a unit of the Chicago Board Options Exchange (Cboe), has filed a rule change application with the U.S. Securities and Exchange Commission (SEC) to launch the U.S. market’s first 3x leveraged Bitcoin and Ethereum ETFs. Per the filing, Cboe plans to list ETFs including 3x Bitcoin ETFs, 3x Ethereum ETFs, and 3x leveraged ETFs for gold, silver, crude oil, and natural gas. These products aim to deliver 3x the daily returns of their underlying assets by holding futures contracts from the Chicago Mercantile Exchange (CME) or the New York Mercantile Exchange (COMEX), with cash and cash equivalents serving as collateral. The proposed ETFs will operate as "commodity pools" regulated by the U.S. Commodity Futures Trading Commission (CFTC), rather than the traditional ETF structure overseen by the SEC under the Investment Company Act of 1940. As leveraged products do not meet the exchange’s existing general listing standards, Cboe is required to file a special rule change application with the SEC and plans to concurrently submit an S-1 registration statement under the Securities Act of 1933. Cboe stated that this structure will provide an additional federal regulatory layer. The funds will be issued by Volatility Shares LLC and operated under VS Trust. Market analysts note that 3x leveraged ETFs are primarily targeted at short-term trading and professional investors, and are not suitable as long-term holding instruments. Previously, Volatility Shares had launched 2x Bitcoin and Ethereum strategy ETFs in the U.S., while Europe saw the launch of the first 3x and inverse 3x Bitcoin and Ethereum ETF products last year.

Morgan Stanley significantly increased its holdings of Circle to 8.32 million shares in Q2, and added to its positions in Bitcoin and Ethereum ETFs.

Morgan Stanley’s latest 13F filing with the U.S. Securities and Exchange Commission (SEC) shows that as of June 30, it held approximately 16.5 million shares of BlackRock’s IBIT, a 23% increase from the 13.4 million shares held in the first quarter. However, due to a decline in Bitcoin prices during the quarter, the position’s market value fell to $549 million from $667 million, a roughly 18% drop. During the same period, Morgan Stanley also held 2.57 million shares of MSBT worth around $43.3 million, and increased its holdings in Grayscale Bitcoin Mini Trust, Bitwise Bitcoin ETF, and Fidelity’s FBTC, with FBTC positions rising nearly 38%. For Ethereum-related assets, its holdings of ETHA surged approximately 202% to 4.6 million shares, while its stake in Grayscale Ethereum Staking Mini ETF rose by around 26% to 5.1 million shares. Additionally, Morgan Stanley established new positions in Grayscale’s Solana Staking ETF and Fidelity’s Solana Fund, with respective market values of roughly $4.25 million and $2.26 million. In terms of individual stocks, Morgan Stanley’s holdings in Circle (CRCL) jumped from approximately 1.46 million shares to 8.32 million shares. It also expanded positions in crypto mining and infrastructure firms including Cipher Digital, Core Scientific, Hut 8, and Bitdeer. Conversely, it trimmed its Coinbase stake by around 550,000 shares, cut holdings in CleanSpark by more than 3.1 million shares, and liquidated its entire position of roughly 8 million shares in Bitfarms.

JPMorgan boosted its holdings of Bitcoin and Ethereum ETFs in Q2: its stake in IBIT rose by 25%, while its position in ETHA increased more than threefold.

JPMorgan Chase’s latest 13F filing with the U.S. Securities and Exchange Commission (SEC) reveals that as of June 30, the firm held approximately 10.4 million shares of BlackRock’s IBIT—up roughly 25% from the 8.3 million shares it held in the first quarter, with a disclosed holding value of around $356 million. Over the same period, its position in BlackRock’s ETHA rose from roughly 267,000 shares to about 1.17 million shares, an increase of more than three times and exceeding four times its prior holding size. The filing also disclosed small holdings in XRP-related investment products for the first time, including 181 shares of Grayscale’s XRP product and 113 shares of Bitwise’s XRP ETF. Jonatan Randin, senior market analyst at PrimeXBT, pointed out that this 13F covers 18 investment management entities under JPMorgan, with some positions potentially linked to client trades or inventory management. Since 13F filings do not disclose short positions, it is impossible to assess JPMorgan’s net exposure or directional views on Bitcoin (BTC) and Ethereum (ETH) solely based on these long positions. Separately, JPMorgan cut its holdings in multiple Bitcoin mining companies during the second quarter. Randin noted that as some mining firms expand into AI and high-performance computing, their status as proxy assets for Bitcoin prices is weakening.

Grayscale: If the plans to reduce the token inflation rates of Ethereum (ETH) and Solana (SOL) are implemented, it could provide price support.

Grayscale Research Head Zach Pandl published a post stating that the Ethereum and Solana communities are discussing adjustments to their token economic models, with related code changes potentially lowering the annual inflation rates of ETH and SOL, thereby reducing future token supplies. Ceteris paribus, slower supply growth could provide support for token prices. Grayscale estimates that if the relevant adjustments are implemented, by the end of 2031, ETH’s annual supply inflation rate will drop to around 0.4% (close to that of BTC), while SOL’s will stand at approximately 1.1%. By comparison, gold’s annual supply growth rate is roughly 1.8%, and the U.S. CPI inflation rate is about 3.3%. Currently, the relevant proposals are still under discussion within their respective communities. Pandl noted that the Solana-related proposal appears to have broader consensus, making it more likely to be implemented. If the proposals pass, since staking rewards are primarily derived from new token issuance, the number of tokens earned by ETH and SOL stakers will decrease. Pandl pointed out that reduced supply could boost scarcity and exert upward pressure on prices, benefiting holders of unstaked ETH and SOL; whether stakers will benefit depends on the net impact between the reduction in staking rewards and the potential rise in token prices.

Ethereum Foundation abandons the Poseidon hash algorithm, shifting to SHA-2 or BLAKE2 to advance its post-quantum cryptography roadmap.

Ethereum Foundation core researcher Justin Drake announced in a post that Ethereum Layer 1 (L1) will abandon Poseidon, the SNARK-friendly hash function that has been dominant since 2019, in favor of traditional hash functions such as SHA2 or BLAKE2s. This reversal stems from a breakthrough in SNARK design, centered on "hash-friendly SNARKs" rather than the prior approach of "SNARK-friendly hashes". By natively aligning Boolean operations in traditional hashes with binary fields, proof performance for traditional hash calls in SNARKs has reached 1 million per second, with overhead of just around 100x—a stark contrast to the previously extremely expensive operations in large prime fields. Drake dubbed this "science-fiction-level cryptography" and named contributors to key research breakthroughs including Binius and Flock. The shift will push Ethereum’s hash-based cryptography to the peak of minimal assumptions, while drastically accelerating deployment: there is no need to wait for years of cryptanalysis maturity for Poseidon. The Ethereum Foundation’s (EF) post-quantum team is advancing rapidly, with a roadmap targeting a production-grade leanVM in 2027, and deployment of the consensus, execution, and data layers in 2028. Drake also noted that AI’s enhanced cryptanalysis capabilities have recently dealt successive setbacks to lattice-based schemes (HAWK) and isogeny-based schemes (SQIsign), while hash-based schemes are emerging as the leading candidates for post-quantum signatures in blockchains. The trend of open-source automated research is also accelerating; SNARK.fast has achieved 1.8 million BLAKE3 proofs per second.
