Grayscale will convert staking rewards from its Ethereum and Solana ETFs into cash distributions starting around Aug. 7, according to July 17 SEC filings. At the same time, both networks are weighing protocol changes that would cut staking yield at the source, trading investor income for a tighter supply story.
Grayscale's July 17 SEC filings said its Ethereum and Solana staking ETFs would convert staking rewards to cash and distribute them to shareholders at least quarterly, with the changes expected around Aug. 7. Solana and Ethereum are each weighing protocol changes that would reduce that income at the source.
Solana and Ethereum propose cutting issuance
Solana developers want to accelerate disinflation enough to cut modeled staking yield from 5.84% today to 2.25% within three years. The proposal, SIMD-0550, would double the network's annual disinflation rate from 15% to 30%, reaching the 1.5% terminal inflation rate in about 2.8 years instead of 5.7 years under the current schedule.
Under the proposal's 68% staking assumption, modeled nominal yield falls from 5.84% today to 4.34% in year one, 3.00% in year two, and 2.25% in year three. The tradeoff is 18.9 million fewer SOL entering circulation over six years, worth roughly $1.47 billion at SOL's current price near $77.97.
Ethereum researchers have filed a draft proposal, EIP-8363, that would burn an increasing share of validator issuance as the staking ratio climbs, with the burn reaching 100% once roughly half of ETH's supply is staked. One proposal author warned that continued validator entry, without reform, could push more than 70 million ETH, over 55% of supply, into staking by January 2028.
Lower yield trades income for scarcity
Solana's proposal frames native staking yield as something close to a risk-free rate inside its economy. When passive staking pays 5.84%, lending, liquidity provision and other DeFi activity have to clear that bar before taking on additional risk becomes worthwhile. Staking still carries slashing and validator risk, however, a point participants in Ethereum's debate raise to qualify how closely staking resembles a risk-free rate.
Investors who hold Ethereum or Solana without staking benefit most directly, since reduced issuance means less dilution reaching their share of the network. Both proposals also pull the Ethereum and Solana investment pitch a step closer to Bitcoin's supply story.
The ETF income squeeze
Grayscale's distribution framework standardizes how quickly whatever income exists reaches a brokerage account, so a shrinking pool of protocol-level rewards eventually means a shrinking pool available to distribute. Ethereum's debate also raises sharper concerns about smaller solo validators, since large custodians and staking companies can spread fixed costs across far more ETH.
Solana's own modeling shows the accelerated schedule pushing 2 additional validators into unprofitable territory in year one, 13 in year two, and 30 in year three, out of 738 modeled validators.
Ethereum and Solana are betting on scarcity over yield. That bet depends on something a protocol upgrade cannot control: how much investors decide scarcity alone is worth.
