Asset manager Grayscale has published an analysis projecting that proposed changes to Ethereum and Solana tokenomics could reduce annual supply inflation to roughly 0.4% for ETH and 1.1% for SOL by 2031, assuming the modifications are implemented.
The projections assume specific protocol upgrades move forward as currently designed. For Ethereum, the figure represents a substantial tightening from current inflation levels. For Solana, the 1.1% projection would be narrower than the network has historically experienced. Both figures depend on the adoption of the tokenomics proposals Grayscale analyzed.
Grayscale's analysis compares these projected inflation rates to traditional assets. Ethereum's potential 0.4% annual supply growth would fall below gold's long-term supply expansion, which sits around 1.8% annually. Bitcoin's maximum issuance cap differs fundamentally from both models as a fixed rather than dynamic supply mechanism.
The projections also account for shifts in staking dynamics under the new tokenomics. Reduced annual supply expansion typically correlates with lower staking yields when network demand remains constant, though actual rewards depend on total value staked and protocol fee mechanisms. Grayscale did not specify whether the analysis assumes constant staking participation rates.
Neither Ethereum nor Solana has finalized the tokenomics changes Grayscale modeled. Ethereum's development roadmap includes multiple competing proposals for supply policy, none yet scheduled for mainnet deployment. Solana's core development teams have explored various tokenomics adjustments without consensus on a single path forward. The projections remain conditional on governance decisions that have not yet materialized.
Grayscale's 2031 timeframe allows substantial runway for either protocol to alter course. Both networks have historically revised tokenomics plans mid-implementation based on network conditions and community feedback. The analysis provides a baseline scenario rather than a locked forecast.
Grayscale's analysis reduces supply inflation for both chains by roughly 60 to 75 percent from their current trajectories if the proposals are implemented as modeled, placing ETH and SOL in a substantially tighter issuance regime than today. The specific inflation floors Grayscale identified, 0.4% and 1.1%, would anchor expectations for scarcity mechanics should these governance paths materialize.
The document to watch is the formal tokenomics proposals from Ethereum and Solana development teams; neither protocol has committed to deployment timelines for the changes Grayscale analyzed.
