Ethereum Staking-Cap Draft Puts 41.4M ETH and DeFi Yield Curves on Notice
A new EIP would burn validator rewards as staked ETH nears 50% of supply. Aave, EtherFi and Fidelity researchers warn of a DeFi capital exodus.
A draft Ethereum Improvement Proposal that would progressively burn validator staking rewards as the network’s staking ratio climbs toward 50% has split the protocol’s research community from its DeFi builders. The proposal, dubbed the Tapered Issuance Burn, is provisionally numbered EIP-8363 by Cointelegraph and EIP-8361 by AMBCrypto — the two outlets differ on the exact reference number, underscoring how fresh and unsettled the draft still is.
A tapering curve tied to a 60.25M ETH threshold
The draft was authored by six Ethereum researchers and developers, including Ethereum Foundation researcher Justin Drake and Jérôme de Tychey. It would burn an increasing share of validators’ consensus-layer rewards as staked ETH approaches a fixed 60.25 million ETH threshold — roughly half of Ethereum’s current ~120 million supply — with the deduction reaching 100% once that ceiling is hit. The change would phase in over 18 months.
Staking demand is currently running at record levels: figures cited put staked ETH at 41.4 million tokens, or 34.4% of supply, while Cointelegraph notes the ratio crossed 33% in April. Ethereum’s current annual issuance sits near 0.8%, with stakers earning roughly 2.62% on staked ETH. Under the existing issuance curve, authors argue yield never drops below 1.5% even if 100% of ETH were staked — a floor de Tychey called a permanent “dilution tax” that never switches off. Without intervention, he warned, more than 55% of supply could be locked in staking by 2028.
“Ever-growing issuance is a dilution tax on every holder: stake, or be diluted. At high ratios, LSTs and other staking derivatives displace raw ETH as the ecosystem’s working money,” de Tychey said, framing the proposal as protecting ETH’s role as a neutral, trustless store of value.
DeFi founders warn of a capital exodus
Aave founder and CEO Stani Kulechov pushed back directly, arguing the reward cut would hit institutional demand for ETH and credit markets built on staking yield. “This just makes ETH less viable as an asset and restricts its potential. I hope this proposal doesn’t move forward; otherwise, we see a lot of people moving their interest in other networks,” Kulechov said, adding separately that the plan “doesn’t achieve the outcome it tries to achieve and is actually hurtful for Ethereum.”
EtherFi CEO Mike Silagadze warned that a roughly 0.8% reduction in issuance is unlikely to move ETH’s price while risking a capital exodus across “seven of the top 10 DeFi protocols.” He also argued the change would disproportionately squeeze solo validators with higher relative costs: “This will self evidently push out solo stakers who aren’t subsidized by the EF or others. It will essentially guarantee that the only ones staking are large centralized entities with zero cost of capital where users passively hold their ETH.” De Tychey disputed that framing, noting large staking providers still charge fees that become less attractive as rewards fall, though he conceded the underlying research is contested.
Fidelity’s Director of Research, Lorenzo Valente, flagged Aave, Morpho, Pendle and Ethena as protocols whose ETH-collateral credit markets would be exposed if staking yield compresses. Ryan Berckmans took a middle position, saying issuance reduction is needed but that cutting the reward to zero goes too far.
Grayscale backing, but timeline questioned
Grayscale has signalled support for the broader direction: the firm’s head of research, Zach Pandl, said in May that capping staking incentives would be “positive for the price of Ether over time,” though Grayscale did not endorse a specific mechanism at the time. On-chain, players such as Bitmine reportedly have more than $10 billion committed to ETH staking, raising the stakes for how any consensus emerges before a policy change goes public.
Timing has also drawn criticism. The draft was published just two days ahead of a Thursday deadline for pull requests targeting Ethereum’s upcoming Hegotá upgrade, prompting EIP-8148/EIP-8205 co-author Greg Koumoutsos to say the process “clearly doesn’t leave adequate time for community review of a monetary policy change of this magnitude.” Ethereum community organizer Trent Van Epps clarified that the Thursday cutoff applies only to submitting proposals, not to deciding which will be included — that selection process runs until November 8, with Hegotá expected to reach mainnet in the second quarter of 2027. The Tapered Issuance Burn has not been approved or scheduled for inclusion.
