- Glamsterdam is scheduled to go live on the Hoodi testnet next week.
- Hoodi will run the same raised gas limit already tested on Sepolia.
- Ethereum developers have not yet set a mainnet date.
- ETH is sitting on support formed by its 200-day average and a Fibonacci level.
Ethereum’s Glamsterdam upgrade will activate on the Hoodi testnet on October 26 at 17:42:48 UTC, the Ethereum Foundation confirmed in its October 16 Hoodi announcement, and Hoodi’s block gas limit will climb to 200 million at the same epoch. The date lands while ETH trades near $2,381, roughly 15% under its late-September peak and parked on a support band around $2,310 that has caught every dip for a week. Hoodi exists mostly for validator and staking operations, which means mainnet users see no change yet, though a clean fork there is the last public step before developers commit to a mainnet slot.
Hoodi Gets 200M Gas Before Mainnet Does
Activation is set for epoch 132,352, slot 4,235,264, twenty days after Glamsterdam went live on Sepolia, whose first public testnet activation already ran the same 200 million gas limit. Every Hoodi operator has to upgrade both execution and consensus clients before the deadline. The Foundation’s release table still showed blanks for some execution clients when the post went live, with go-ethereum, Ethereum’s most widely used execution client, among those still waiting for a confirmed build.

Bigger Blocks, Same 12 Seconds
A higher gas limit lets each block carry more computation, yet every node still has to execute and verify that work inside one twelve-second slot, and pushing more into that window without other changes raises hardware costs until smaller validators drop out. Glamsterdam tackles the problem from the way blocks are built, the way they are checked and the price of the operations inside them.
EIP-7732 moves proposer-builder separation into the consensus rules. Most validators currently hand block construction to specialised builders through relay software that Ethereum’s protocol does not govern. Under the new model a builder commits to a payload, the proposer signs the block around that commitment and the protocol itself checks whether the payload showed up on time, which buys validators extra time to process heavier blocks. The concentration of block building among a few sophisticated firms survives the change, and developers still list it as a risk to watch.
EIP-7928 adds a block-level access list, a record of every account and storage slot a block’s transactions touch together with the resulting changes. Clients today only find that out by running transactions one after another. A node holding the list can pull state from disk in parallel and rebuild the state root with much less sequential work, so a larger block does not have to become a slower one.
Pricing is handled by EIP-8037 and EIP-8038, which reset the gas charged for creating and reading state such as balances, contract storage and deployed code, and several of those operations get more expensive. In its May 2026 protocol update the Foundation tied the 200 million figure to these three changes working together, calling it a credible post-upgrade floor against roughly 60 million on mainnet today. That gas budget is about 3.3 times larger, although transaction counts will not scale by the same factor, because Glamsterdam also rewrites how intrinsic gas is counted and real blocks mix cheap transfers with heavy DeFi calls.
The Contracts That Hardcoded Gas
Foundation researchers replayed historical mainnet transactions under the new schedule for an August 24 repricing report and found that the vast majority behaved exactly as before. The small group that diverged ran from transactions that merely burned a different amount of gas to a handful of contracts that kept failing even with a much higher limit. Contracts that fix gas allowances in their code or assume how much gas is left mid-execution carry the most exposure, and developers can check individual addresses with the repricing impact checker before mainnet. The report flags no direct threat to user funds, yet it is the main reason Hoodi carries more weight than the gas headline suggests.
$2,310 Is Where Two Supports Meet
On the daily chart, the pullback from the $2,809 high has carried ETH into the area where the 200-day EMA at $2,314 almost overlaps with the 0.382 Fibonacci retracement of the June to September rally at $2,311. Traders tend to treat that kind of overlap as a serious line, because the 200-day EMA tracks the long-term trend and the 0.382 level marks the depth where corrections inside an uptrend usually attract buyers.
Several daily candles over the past week dipped toward $2,320 and left long lower wicks before closing higher, showing bids parked inside the zone. Volume backs that up, since the heaviest selling came with the early October break below $2,600 and the daily bars have since shrunk to some of their lightest readings in two months, with the October 20 session at about 71,000 ETH by midday. When a decline loses volume on its way into major support, it usually means sellers are running out of urgency rather than starting a fresh wave of distribution.
Momentum has yet to confirm a turn, with the 14-day RSI at 35.7, below its signal line at 39.5 and still sloping down, which leaves room for one more push toward the 30 area where ETH bottomed in June. The golden cross from late August holds, with the 50-day EMA about $165 above the 200-day, but the 50-day at $2,479 has started to roll over just under the 0.236 retracement at $2,502, making the $2,480 to $2,500 band the first ceiling any recovery must clear.
Distance from the current price
A daily close back above $2,500 would put ETH back into the range it held for most of September and reopen the way toward $2,600 and the $2,809 high. Losing $2,310 on a closing basis would break both supports in one move and expose the 0.5 retracement at $2,157, with the August breakout base near $1,900 underneath and the 0.786 level at $1,784 as the deeper target if selling picks up speed.
The Burn Rate Is the Real Test
A smooth fork on Hoodi would hand client teams the evidence they need to propose a mainnet slot on the All Core Developers calls, where the date gets fixed, while a rough one would stretch a schedule that has already slid from an original June target into the fourth quarter. For ETH holders the harder question arrives after mainnet. More capacity tends to lower the fee per transaction, and with it the amount of ETH burned, unless activity grows fast enough to fill the bigger blocks. Much of Ethereum’s usage already lives on layer-2 networks that have no built-in reason to move back to a cheaper base layer, so gas utilization, fee revenue and the burn rate in the weeks after activation will show whether the extra room gets used.
Early December has come up in developer planning discussions as a possible mainnet window, though the Foundation has not confirmed any date and the Hoodi results will weigh on that decision. Planning for Hegotà, the upgrade lined up to follow Glamsterdam, is already running in parallel according to the same May protocol update.
Wall Street’s Deposits Land on Layer 1
In separate news, JPMorgan said on October 19 that it is bringing JPM Coin to the Ethereum mainnet, extending its dollar deposit token beyond Base, where it has been available to institutional clients since November 2025. JPMD is a claim on money held at the bank rather than a reserve-backed stablecoin, so it can carry interest, and only approved institutional wallets can hold or transfer it. The move puts bank cash on the same chain as JPMorgan’s tokenized money market funds, including JLTXX, which went live on Ethereum in May with $100 million committed at launch. The bank has not disclosed how much JPMD it expects to issue on mainnet, and the near-term effect on ETH demand may stay small, since a large institutional settlement consumes the same gas as a modest transfer.
