Grayscale said in July 17 filings with the SEC (U.S. securities regulator) that its Ethereum and Solana staking ETFs would convert staking rewards into cash and distribute the proceeds to shareholders at least quarterly, with the changes expected around Aug. 7. The structure would bring staking (locking crypto to earn rewards) income into an ETF format that resembles a dividend-style payout for traditional investors. At the same time, both Ethereum and Solana are considering protocol adjustments that could lower the rewards feeding those funds. The source says Solana developers want to accelerate disinflation (a slower growth rate of token supply), which would reduce staking income at the network level.
