SharpLink, a major Ethereum staking participant, has declared its opposition to EIP-8363, a draft proposal designed to burn a portion of validator rewards as the network's staking ratio increases. Joseph Chalom of SharpLink published his firm's stance on Friday, arguing the proposal poses a direct economic challenge to the Ethereum ecosystem.
EIP-8363, officially titled "Tapered Issuance Burn," aims to modify the ETH issuance curve by gradually burning validator consensus-layer rewards. The proposal suggests phasing in this reduced issuance schedule over approximately 18 months, with a growing share of validator yield burned as more ETH is staked on the network.
The draft outlines a mechanism where validator yield would progressively decrease until it reaches zero percent when roughly half of all ETH is staked. At that point, validators would rely solely on transaction tips for revenue, which currently account for only 15 percent of total staking yields.
Chalom's central objection centers on staking yield as the de facto base rate for decentralized finance. He argues that yield is critical for the functioning of on-chain lending protocols and broader DeFi infrastructure.
Liquid staking tokens, which represent staked ETH and are widely used as collateral across DeFi, currently command approximately $35 billion in total value locked. Removing the underlying yield from these assets would not redirect value within the ecosystem but would destroy it, Chalom said.
The proposal also threatens the institutional investment case for ETH. Chalom said EIP-8363 would eliminate the distinction that makes Ethereum a natively productive asset compared to Bitcoin, potentially prompting institutions to unstake and sell their ETH holdings.
SharpLink's own ETH is staked with several major validators, including Coinbase, Anchorage, Figment and Galaxy Digital. The firm also backs ether.fi, Linea and EigenCloud, giving it direct exposure to the proposed changes.
Ethereum already incorporates a mechanism for managing ETH scarcity through its base fee burn, which makes the asset deflationary when network usage surpasses a specific threshold. Chalom characterized EIP-8363 as an economic and business challenge, not a technical one.
The proposal remains in the discussion stage among Ethereum researchers and developers. Its initial draft was dated Aug. 4, and it was introduced as a topic on Ethereum Magicians, a forum for protocol development discussions.
Chalom acknowledged the draft faces a difficult path to implementation, saying the odds of it passing are long, but argued its implications for the DeFi landscape are significant regardless of its final outcome.
