Aave's Kulechov and Sharplink Oppose Ethereum Staking-Burn Proposal EIP-8363

Aave founder Stani Kulechov and Sharplink have come out against EIP-8363, a draft Ethereum proposal that would progressively burn validator rewards to zero as more ETH gets staked. The opposition pits major DeFi stakeholders against a group of Ethereum Foundation researchers over how the network should compensate those who secure it — a foundational question for a proof-of-stake blockchain where validators must lock up capital to participate in consensus and face penalties for misbehavior.

The Tapered Issuance Burn Proposal

The proposal, titled "Tapered Issuance Burn," was posted on GitHub on August 4, 2026. It calls for a mechanism in which the network would destroy an increasing share of the rewards distributed to validators.

Under the proposed system, once staking reaches approximately 60.25 million ETH — close to half of the total supply — the burn rate would reach 100%, and new-issuance yield would be eliminated entirely. At that point, validators would rely solely on transaction tips and maximum extractable value (MEV) — the profits validators can capture by reordering, including, or excluding transactions within the blocks they produce — for income.

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

The proposal remains a draft and has not been accepted into any network upgrade. According to Cryptopolitan's earlier reporting, the authors suggested the new system be phased in over an 18-month transition period to ease the impact.

DeFi Industry Opposition

Major DeFi participants have pushed back against the proposal, arguing that staking rewards have effectively become a base interest rate for the Ethereum economy. Liquid staking tokens such as Lido's stETH and Ether.fi's eETH — transferable tokens representing staked ETH that accrue rewards — are valued at approximately $35 billion combined and serve as collateral across lending markets.

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

The proposal emerges 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.

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

Ether.fi CEO Mike Silagadze offered a $1 million wager that the proposal, if adopted, would lead to validator concentration. He argued that solo stakers tend to exit when yields fall, while large custodians such as Coinbase (NASDAQ: COIN) and Binance continue staking customer ETH at near-zero cost. The dynamic he describes echoes a broader concern in the Ethereum community: centralized exchanges and liquid staking providers already account for a substantial share of staked ETH, and any policy that disproportionately disadvantages independent validators could accelerate that trend.

Proposal Authors and Their Rationale

The six authors — pintail, Jérôme de Tychey, dapplion, pa7x1, Ladislaus von Daniels, and Justin Drake — contend that the current issuance system lacks an "off switch." Even if all ETH were staked, they note, the yield would not drop below approximately 1.5% annually. This dynamic, they argue, creates a "dilution tax" on non-staking holders and could accelerate the concentration of ETH among large custodians and liquid staking providers — notably the same outcome critics of their proposal warn about.

They maintain that their proposed mechanism would eliminate 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 consideration for the Hegotá upgrade. The proposal selection process is estimated to continue until November 8, 2026, with the Hegotá upgrade projected for Q2 2027.

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