What to know:
- Sharplink opposes EIP-8363, citing risks to DeFi, staking returns, and network security.
- EIP-8363 would burn all issuance rewards once about 60.25 million ETH enters staking.
- Kulechov warns zero rewards could make Ethereum staking uneconomical and less secure.

Sharplink has opposed Ethereum Improvement Proposal 8363. The digital asset firm called it the wrong proposal at the wrong time. It warned that the draft could weaken DeFi, staking returns, institutional demand, and network security.
Chief Executive Joseph Chalom listed four reasons for the company’s opposition in a post on X. The first concerned Ethereum’s decentralized finance sector. Sharplink said staking yield acts as a base rate for onchain markets after costs and inflation.

Sharplink Says EIP-8363 Could Weaken Ethereum DeFi
Staking tokens have a TVL of around $35 billion and are used as collateral in different lending systems. Low interest rates can increase the cost of on-chain money.
The firm said that operating costs, liquidity costs, and slashing risks can make actual returns close to zero or lower than that.
It further stated that lower interest rates can lead to collateral withdrawal from the Ethereum network, making lending markets thinner and decreasing credit availability in the DeFi space. It was only the stakers and medium-sized entities that could be impacted by this issue.
The EIP-8363, called Tapered Issuance Burn, is a draft that proposes a shift in the existing staking reward system on Ethereum.
According to the draft, more and more of validators’ rewards generated from attestations, block proposals, and sync-committees will be burned as more ETH will be staked.
The burn will be complete at 100% after about 60.25 million ETH, or half of all issued ETH, have been staked. The rate of issuance yield will drop to 0%. Validators will receive tips and MEV (maximal extractable value), rather than issuance rewards.
Why Native Yield Matters to ETH Investors
The second objection raised by Sharplink was that of institutional demand for ETH. It argued that because ETH provides native yield to the holder, it offers an edge over other assets due to its yield. The company highlighted increasing exposure through exchange-traded products, digital asset trusts, and private funds.
The third point highlighted that the internal finance mechanism used by Ethereum helps cover the costs of securing the network, operating nodes, maintaining client software, and investing in the system. Thus, reducing the rewards would stop the capital inflow altogether.
The firm also said reduced rewards would encourage institutions to sell their ETH after unstaking. Sharplink linked its timing objection to recent activity by traditional financial companies. It cited stablecoins, tokenized assets, and new projects built on Ethereum.
Why Sharplink and Kulechov Oppose EIP-8363
Robinhood is developing a Layer-2 chain, while BlackRock had already launched tokens representing a money-market fund on Ethereum.
Meanwhile, BNY and Galaxy Digital have launched their staking alliance. The firm said that the EIP-8363 arrived as these institutional developments gained pace across the ecosystem.
Aave founder and CEO Stani Kulechov has raised concerns about related issuance plans. He said zero rewards above a 50% staking ratio could make returns unpredictable or uneconomical. He warned that this outcome could reduce participation and weaken the network.
Kulechov later described Sharplink as one of the supporters and funders of the Ethereum ecosystem. However, EIP-8363 is still in a draft state and has neither been accepted nor scheduled for an Ethereum upgrade.
