Aave founder Stani Kulechov and Sharplink have publicly opposed EIP-8363, a draft Ethereum proposal that would progressively burn validator issuance rewards as more ETH is staked, positioning themselves against a group of Ethereum Foundation researchers over how the network should compensate those who secure it. The debate touches on a core tension in Ethereum's proof-of-stake system, live since the network's September 2022 Merge replaced energy-intensive mining with validator-based consensus: how to balance predictable staking yields against the risk of over-concentration.

The Tapered Issuance Burn Proposal

The proposal, titled "Tapered Issuance Burn," was posted on GitHub on August 4, 2026. It calls for a system in which the network would destroy a growing share of validator rewards as staking levels rise. According to a Messari report, once staking reaches approximately 60.25 million ETH—close to half the total supply—the burn would reach 100%, and new-issuance yield would disappear entirely. At that point, validators would earn only from transaction tips and maximum extractable value (MEV)—the extra income validators capture by reordering, including, or excluding transactions within blocks.

Currently, about 41.5 million ETH is staked, representing roughly 34% of the total supply. If EIP-8363 were activated now, validator income would decline from approximately 2.68% to about 1.19%, a reduction of roughly 55%.

The proposal remains a draft and has not been accepted into any upgrade. As previously reported, the authors suggested introducing the new system over an 18-month transition period to soften its impact.

DeFi Industry Opposition

Major DeFi participants have pushed back against reducing staking rewards, arguing that staking yield has effectively become a base interest rate for the Ethereum economy. Liquid staking tokens such as stETH and eETH, valued at approximately $35 billion combined, are widely used as collateral across lending markets, meaning that changes to staking yield ripple through borrowing costs, leverage, and liquidity throughout decentralized finance.

Sharplink CEO Joseph Chalom posted his concerns on X, stating that if staking rewards decline sufficiently, validators could operate at a loss after accounting for equipment, electricity, and other operational costs. He noted that ETH's ability to generate staking rewards is one reason institutional investors favor it over cryptocurrencies that offer no yield. He also argued that staking rewards do not constitute a true cost, as they represent ETH transferred from one holder to another.

Kulechov echoed these concerns on X, describing Sharplink as "one of the largest Ethereum ecosystem supporters and funders" and endorsing Chalom's points on feasibility and timing. "Save ETH staking," he wrote, warning that compressing liquid staking token yields could undermine a significant portion of DeFi lending markets.

Ether.fi CEO Mike Silagadze offered a $1 million bet that the proposal, if adopted, would concentrate validation power among large operators. He argued that solo stakers tend to exit when yields fall, while major custodians such as Coinbase (NASDAQ: COIN) and Binance continue staking customer ETH at near-zero cost. Ethereum has long treated solo staker participation—running a validator node independently of a custodian or exchange—as a decentralization safeguard, since a high share of staked ETH flowing through a few large providers would give those providers outsized influence over transaction ordering and protocol governance.

The proposal comes amid a wave of institutional activity on Ethereum, including a Robinhood layer-2 network, BlackRock (NYSE: BLK) tokenizing a money-market fund, and a staking partnership between BNY (NYSE: BK) and Galaxy Digital.

Proposal Authors and Supporters

The six authors—pintail, Jérôme de Tychey, dapplion, pa7x1, Ladislaus von Daniels, and Justin Drake—argue that the current issuance system has no "off switch." Even if all ETH were staked, they contend, the yield would not fall below approximately 1.5% annually. This creates what they describe as a "dilution tax" for non-staking holders and could paradoxically push more ETH toward large custodians and liquid staking providers. Their proposed mechanism aims to remove the incentive for unlimited stake growth and preserve ETH's neutrality as an asset.

During the August 6 All Core Devs call, the presenting author indicated they are considering withdrawing the proposal from Hegotá consideration. The selection process for proposals is estimated to run until November 8, 2026, with the Hegotá upgrade projected for Q2 2027.

ARK Invest research director Lorenzo Valente pushed back against critics of a related issuance change, stating that ETF issuers focus on assets under management and take rates rather than chasing yield.
