Curve Finance says the value of Ethereum’s Glamsterdam upgrade should be judged by how transactions behave when the network is busy, not by the headline block gas limit. According to Crypto.news, the protocol pointed to mainnet checks in which a leveraged borrow consumed about 1.84 million gas, while a direct stablecoin swap used 125,000.
That gap — roughly 14.7 times — is the basis for Curve’s case that complex DeFi operations are disproportionately exposed when blockspace gets scarce. The team said the practical measures of success are how quickly transactions enter blocks and what users actually pay when demand spikes.

Key facts
- Curve’s mainnet checks measured a leveraged borrowing transaction at about 1.84 million gas against 125,000 for a direct stablecoin swap.
- Ethereum developers prepared a 200 million gas test but did not commit mainnet to that limit.
- Prysm’s version 7.2.1 release added the Sepolia schedule so validators would default to 200 million gas after the fork; the prior version retained the 60 million setting unless operators changed their configuration.
- Curve warned that Glamsterdam reprices state operations: EIP-8037 changes the cost of creating state, including accounts and contract storage, while EIP-8038 revises charges for accessing existing state.
- Alongside its reporting, Cryptobriefing noted that Glamsterdam aims to lift Layer 1 execution capacity through changes that include block-level access lists and parallel processing, and that the upgrade had been tested on the Sepolia testnet with a raised block gas limit.
What Curve expects from more blockspace
In notes shared with Crypto.news, Curve said added capacity would matter most for borrowers, arbitrage traders and liquidators when activity is heavy. For transactions that combine borrowing with a collateral purchase, congestion can interfere with several parts of the same operation, which is why the team framed predictable blockspace access as the real test.
Cheaper execution could also make smaller arbitrage trades worth completing, Curve said, and longer swap routes could become more economical — potentially improving prices available through its pools and making positions easier to open or unwind.

The expected benefit for Curve’s lending system runs through LLAMMA, its liquidation mechanism. According to the team, cheaper and faster arbitrage should help LLAMMA track market prices more closely as collateral moves through its liquidation range, reducing losses when prices shift before transactions finish. Curve also tied dependable liquidations to the stability of crvUSD, the stablecoin it issues, and placed particular weight on behavior during volatility, when users need to act on positions rather than wait for congestion to clear. The team said what should be watched most closely is execution under real load.
The trade-off: repriced state operations
Curve stopped short of claiming every user action would get cheaper. The protocol flagged that Glamsterdam reprices state operations, so some transactions would require more gas. Ethereum developers raised related compatibility concerns in an Aug. 26 report; the Ethereum Foundation warning covered there said most contracts were unaffected in transaction replays, while many flagged failures could be fixed by supplying higher gas limits. Fixed gas allowances, hardcoded call limits and gas-sensitive contract logic were among the risk factors, and the warning extended to wallets, infrastructure providers and gas-estimation tools that rely on cached assumptions. Developers were urged to test applications before mainnet activation.
On validation, Curve said Ethereum should preserve the ability to verify its ledger without asking permission, warning that scaling would compromise that principle if added capacity made independent verification impractical.
Earlier reporting on Glamsterdam builder risks covered a developer warning that free test ether could let malicious builders win block auctions and withhold transaction payloads — treated as a public-testnet availability concern rather than a way to steal mainnet ETH. In that coverage, Devnet-11 used 84,000 validators across multiple clients, but the controlled rehearsal excluded deliberate attacks. On the market side, a Sep. 19 report on U.S. Ether ETF withdrawals recorded about $140.6 million in net outflows for Sep. 14-18, based on Farside data, with Ether the weakest of the four crypto ETF categories covered.
Cryptobriefing separately framed the upgrade as potentially supportive of Ethereum prices by improving DeFi capabilities, while noting that prediction markets remain mixed and that mainnet activation timing is the key variable. That is a market interpretation, not a projection by Curve, and it is not financial advice — crypto markets are volatile and uncertain.
Why it matters
Ethereum’s block gas limit has long shaped what DeFi users can do at peak demand, and Curve’s figures give that constraint a concrete price: the difference between a simple swap and a multi-step lending position. If Glamsterdam delivers more reliable inclusion, the beneficiaries are the users whose strategies depend on several transactions landing together — liquidators, arbitrageurs and borrowers managing collateral.
The counterweight is repricing. Higher gas requirements for state-heavy operations could offset some of the capacity gain for contracts and wallets built on fixed assumptions, which is why the Ethereum Foundation pushed developers to test before mainnet. The upgrade also lands against a softer stretch for U.S. Ether funds, a reminder that network improvements and market flows do not always move together.
What to watch
The Ethereum Foundation had not set Hoodi or mainnet activation dates and said separate announcements would follow agreement among client teams. Those dates, and how transactions perform under load once they arrive, are the next concrete data points.
