Ethereum's Glamsterdam upgrade has entered its final devnet stage, pushing the network toward a 200 million gas limit target expected by the second half of 2026. The upgrade is designed to significantly improve efficiency and scalability — but it could also reshape ETH supply dynamics and staking yields.
What the upgrade targets
Glamsterdam aims to raise Ethereum's gas limit from the current ~30 million to 200 million. That's a roughly 6.7x increase, meant to let the network handle more transactions per block without raising fees. Developers have been testing the change on a dedicated devnet — the last step before a public testnet and, eventually, mainnet activation.
Why the final devnet matters
A devnet is a developer-only test environment where core contributors stress-test code before exposing it to the wider community. Reaching the final devnet stage means the upgrade's code is considered feature-complete. Any bugs found now will be patched before the next phase. For users, it signals that the gas limit increase is no longer just a proposal — it's actively being readied for production.
Potential ripple effects on ETH supply and staking
Higher gas limits could boost network activity and fee revenue, which in turn might affect how much ETH is burned via EIP-1559. That could tighten supply over time. Meanwhile, validators may see shifts in staking yields as block space expands and fee dynamics change. The exact impact will depend on transaction demand — but the upgrade introduces a new variable for those watching ETH's monetary policy.
Developers haven't announced a hard date for mainnet activation, but the target remains the second half of 2026. The final devnet will run for several weeks while engineers monitor performance. If all goes smoothly, the upgrade will move to a public testnet, then to Ethereum mainnet via a scheduled hard fork. No official block number has been locked in yet.
