Ethereum’s Glamsterdam upgrade could reshape institutional staking rewards, MEV access, validator reliability, fee dynamics, and liquidity planning.
Ethereum’s Glamsterdam upgrade (EIP-7773) is planned for the first half of 2026. For institutional stakers, the upgrade matters because it may affect the drivers of staking rewards: execution-layer rewards, MEV access, fee dynamics, validator performance, and withdrawal planning.
In this blog, we cover:
Some staking-specific proposals, including exit queue changes, remain under consideration. For institutional stakers, the key question is how these changes affect reward variability, reward reliability, and access to liquidity.
Glamsterdam’s main consensus-layer change is enshrined proposer-builder separation (EIP-7732), commonly known as ePBS.
Today, validators that outsource block construction typically use sidecars like MEV-Boost/ Commit Boost, which connects them to builders through third-party relays. This gives validators access to builder markets and can improve execution-layer rewards, but it also introduces trust assumptions outside the base protocol.
ePBS moves more of the proposer-builder exchange into Ethereum itself. It introduces in-protocol mechanics for payload delivery, builder commitments, and proposer payments. Ethereum.org notes that ePBS removes the need for middleware such as MEV-Boost/Commit Boost for the core payload-payment exchange, although off-protocol tools may still be used for more advanced features.
For institutional stakers, ePBS is mainly about MEV access and reward variability.
A more protocol-native builder market could reduce reliance on third-party relays over time and make MEV delivery more trust-minimized. It may also increase builder competition, which could improve block value capture and support the execution-layer component of staking rewards.
The near-term impact is likely to depend on adoption. If ePBS builder participation is broad and competitive, institutions may benefit from a more resilient MEV market. If adoption is slower, MEV-Boost and relay infrastructure may remain important for longer. Blockdaemon will monitor builder market development, client readiness, and MEV configuration as implementation details mature.
The execution-layer headliner is Block-Level Access Lists (EIP-7928), or BAL. BAL allows a block to declare the accounts, storage slots, and code it expects to access before execution begins.
By surfacing state dependencies earlier, BAL gives execution clients a stronger basis for parallel I/O, parallel transaction processing, and more predictable validation under higher gas limits. Ethereum.org describes BAL as a way to provide an upfront map of transaction dependencies, helping clients prepare for parallel processing and faster syncing.
For institutional stakers, BAL is about protecting reward reliability as Ethereum scales.
Validator rewards depend on consistent participation. Missed attestations, delayed block processing, or client performance issues can reduce realized staking rewards. As blocks become larger or more complex, predictable execution becomes more important.
BAL helps reduce uncertainty in the validation path. That supports more consistent validator performance under heavier block loads, which is important for institutions focused on stable, risk-adjusted staking rewards.
For Blockdaemon customers, this means we prepare for higher-capacity blocks by testing client behaviour, monitoring performance variance, and reducing the risk that execution-layer complexity affects validator participation.
State Creation Gas Cost Increase (EIP-8037) is scheduled for inclusion in Glamsterdam. Its role is to make state growth more expensive and more consistently priced across different ways of creating new Ethereum state.
This matters for rewards because Ethereum can only scale sustainably if validators and nodes can continue to verify the network efficiently. Higher gas limits may increase throughput, but without controls on state growth, long-term node requirements can rise and weaken decentralization.
EIP-8037 introduces a separate state-gas dimension and a cost-per-state-byte model. The goal is to align the cost of creating state with the long-term burden it places on the network.
For institutional stakers, EIP-8037 is less about immediate rewards and more about the sustainability of Ethereum staking.
A healthier scaling model supports long-term network participation, client diversity, and validator performance. That matters because staking rewards are not only a headline PRR. They also depend on the network remaining operationally sustainable and broadly verifiable over time.
EIP-8037 may also affect transaction cost patterns for applications that create new state. Those changes could influence network activity, fee generation, and the execution-layer portion of staking rewards. The impact will depend on demand, application behaviour, and how the broader market responds to the new pricing model.
Increased exit and consolidation churn (EIP-8061) is a proposed consensus-layer change that would adjust Ethereum’s exit and consolidation churn limits. Unlike ePBS, BAL, and EIP-8037, it remains under consideration rather than part of the scheduled Glamsterdam set as of May 2026.
Churn limits control how much stake can activate, exit, or consolidate over a given period. They protect Ethereum by preventing the validator set from changing too quickly.
For institutional stakers, exit queues affect liquidity planning and realized portfolio flexibility.
Long queues can make it harder to rebalance exposure, rotate providers, meet treasury requirements, or respond to market and counterparty risk events. That does not directly change the protocol reward rate, but it can affect how institutions manage staking positions and liquidity risk.
If implemented, EIP-8061 could improve exit throughput during congested periods and make withdrawal planning more predictable for large ETH positions. It would not make Ethereum staking instantly liquid. Churn limits would still exist, and the proposal is currently marked as 'Considered for Inclusion', so final inclusion, timing, and parameters remain subject to change.
Gas is Ethereum’s unit for measuring computational work. The gas limit defines how much execution can fit into each block. Raising it increases Layer 1 capacity, but it also changes the economics of blockspace.
At the Soldøgn Interop, Ethereum contributors aligned on a post-Glamsterdam gas limit floor of 200M, stable ePBS implementations running with external builders, and final EIP-8037 repricing numbers.
A 200M gas floor would move Ethereum from a roughly 60M gas limit to more than three times today’s execution capacity. EIP-8037 supports that scaling path by helping ensure higher throughput does not translate directly into uncontrolled state growth.
For institutional stakers, higher gas capacity may change reward assumptions.
If blockspace supply rises faster than demand, base fees may fall. That can benefit users, but it may reduce ETH burn and lower the fee-derived component of validator rewards. Staking rewards also reflect priority fees, MEV, network activity, validator participation, and broader demand for Ethereum blockspace.
The result is not automatically positive or negative. Higher capacity can support more activity over time, but it may also compress some fee-driven reward components if demand does not scale at the same pace.
For institutions, Ethereum upgrades are staking events as much as infrastructure events. Each fork can affect reward composition, MEV workflows, validator performance, and liquidity planning.
Blockdaemon manages Ethereum protocol upgrades on behalf of customers across its staking infrastructure. This includes monitoring upgrade timelines, testing client releases, assessing MEV and relay changes, tracking exit queue dynamics, and modelling how protocol changes may affect staking reward assumptions.
Customers do not need to manage these changes alone. Blockdaemon’s role is to absorb the operational complexity of Ethereum upgrades while helping institutions maintain secure, reliable, and performant staking operations as the protocol evolves.
