Sharplink CEO Joseph Chalom has criticised EIP-8363, an Ethereum Improvement Proposal that would cap staked ETH by burning validator rewards, arguing it would harm DeFi, weaken Ethereum’s security, and undermine its institutional appeal. The proposal, introduced earlier this week, aims to reduce issuance yield as staking ratios rise, with critics warning it could disproportionately affect solo stakers.
EIP-8363 would burn 100% of validator rewards once 50% of ETH is staked, a threshold expected to be reached in the second half of the year. The changes, which would take 18 months to phase in, have drawn opposition from key figures in the Ethereum ecosystem, including Sharplink’s founder and Ethereum co-founder Joe Lubin.
Justin Drake, an Ethereum Foundation researcher, and Jérôme de Tychey, founder of EthCC, co-authored the proposal. However, Stani Kulechov, founder of DeFi lending protocol Aave, reportedly called EIP-8363 “hurtful for Ethereum,” citing potential adverse effects on the network’s long-term sustainability.
Chalom, who described the proposal’s authors as “serious researchers,” argued that burning issuance yield could weaken Ethereum’s appeal to institutional investors. He stressed that issuance is a systemic transfer, not a cost, and warned that EIP-8363 might stifle innovation in decentralised finance.
The timeline for EIP-8363 has been scrutinised, with the proposal submitted two days before the deadline for inclusion in the Hegota hardfork. Critics say this rushed process risks unintended consequences, though the proposal remains under consideration and could still be rejected.
Sharplink, the second-largest publicly traded Ethereum treasury firm, has positioned itself as a vocal opponent of the change. The firm’s stance reflects broader concerns within the Ethereum community about balancing protocol upgrades with the needs of stakers and institutional users.
Ethereum Institutional, a non-profit focused on attracting institutional adoption, has not yet commented on the proposal. Meanwhile, EthSystems, a for-profit firm spun from the Ethereum Foundation, continues to develop tools for corporate privacy, a sector that could be affected by changes to staking dynamics.
