Solana Proposes Dual Supply Controls: Resource Fees and Accelerated Disinflation

Woofun AI reports that Solana is currently evaluating two distinct governance proposals designed to fundamentally alter its token economics through supply-side constraints. The first initiative, SGP-0003, advocates for the adoption of a resource-based fee model as outlined in SIMD-0553, which seeks to increase the amount of SOL burned through transaction costs. The second proposal, SIMD-0550, targets the inflation schedule itself, proposing an accelerated decline in the annual issuance rate of new tokens. These mechanisms operate independently and are at different stages of development, requiring separate governance approvals, technical implementations, and activation processes before they can impact the mainnet. Neither proposal is currently active, but their combined potential effect represents a significant shift in how the network manages its monetary policy and validator incentives.

The current fee structure on Solana relies on a flat base fee of 5,000 lamports per signature, a model that fails to account for the varying computational demands placed on the network. Under this system, half of the fee is burned while the other half is distributed to the block leader, creating a uniform cost regardless of whether a transaction is a simple transfer or a complex application requiring substantial compute and account data. This inefficiency means that lightweight transactions subsidize heavy ones, distorting the true cost of network usage.

The proposed resource-based model aims to rectify this by decoupling the fee into priority fees, which remain unchanged and go to the block leader, and resource charges that reflect the actual capacity reserved by the transaction. This structural change would allow efficient transactions to pay less while applications reserving large amounts of compute or account data would face considerably higher costs, aligning fees more closely with actual resource consumption.

Implementing this new fee model requires significant updates across the ecosystem, particularly for wallets, RPC providers, and decentralized applications, which must adjust their fee estimation algorithms prior to activation. Without these updates, users risk facing unexpectedly high costs if their transactions reserve more capacity than necessary, even if the program ultimately consumes only a fraction of that reserved power. The proposal acknowledges a potential vulnerability in its earliest stages: very small spam transactions could initially face a lower minimum cost than under the current flat system, potentially encouraging low-value noise.

However, subsequent stages of the implementation plan to raise the resource charge to mitigate this risk. Developers are expected to have a stronger incentive to set accurate resource limits rather than relying on oversized default budgets, thereby optimizing network efficiency and reducing unnecessary overhead.

Based on network activity recorded in May 2026, the authors of the proposal estimate that the new resource fee model could significantly increase the daily burn rate of SOL. Currently, Solana burns approximately 648 SOL per day through the destroyed portion of its base transaction fee. Under the proposed model, this figure could rise to a range that equates to roughly 2.7 million to 3.3 million SOL per year.

These figures are projections rather than guaranteed outcomes, as they assume that transaction activity and requested resource use remain broadly comparable to the May 2026 data used in the model. Higher network activity or more resource-heavy transactions would naturally increase the burn, while developers reducing unnecessary compute requests could lower the fee paid by each transaction. Conversely, higher costs might discourage some activity, potentially reducing the total fees generated and linking the burn rate more closely to actual demand for network resources.

SIMD-0550 addresses the supply side by proposing a change to Solana’s inflation schedule, which currently declines by 15% each year until it reaches a long-term floor of 1.5%. The proposal suggests increasing this annual reduction rate to 30%, accelerating the path to the terminal inflation rate. This change would not result in an immediate halving of the inflation rate; instead, the rate would continue from its existing level and fall more quickly each year thereafter. Using an inflation rate of approximately 3.82% as of June 1, 2026, the proposal estimates that Solana would reach the 1.5% floor almost three years earlier than under the current schedule. This accelerated disinflation aims to reduce the long-term dilution of existing holders by slowing the creation of new tokens, thereby altering the supply dynamics without changing the ultimate target inflation rate.

Woofun AI data shows that the long-term supply impact of SIMD-0550 is projected to be substantial, with the proposal estimating that approximately 18.9 million fewer SOL would be created over a six-year period. This reduction would leave the total supply around 2.6% lower than under the current inflation schedule. It is crucial to note that this does not remove 18.9 million SOL already in circulation; rather, it represents tokens that would no longer be issued compared with the existing inflation path. When combined with the increased burn rates from SIMD-0553, these two proposals would influence different parts of Solana’s supply growth. SIMD-0553 would destroy more existing SOL when transactions use network resources, while SIMD-0550 would reduce the amount of new SOL distributed through staking rewards. Together, they aim to create a more balanced supply-demand dynamic by curbing both issuance and enhancing destruction.

Despite these measures, the proposals would not immediately render SOL deflationary. The fee model estimates that Solana currently issues around 60,000 SOL per day through inflation, a figure that vastly exceeds the projected terminal burn of 7,500 to 9,000 SOL per day. Even with the accelerated disinflation from SIMD-0550, the difference between issuance and burns would only gradually narrow over time.

Whether Solana ever reaches net deflation would depend on future network activity, transaction complexity, staking participation, and the final fee rates adopted. The more likely near-term result is slower supply growth rather than a shrinking total supply. Burning more SOL and issuing fewer new tokens could improve the supply-demand balance if network use and investor demand remain stable or grow, but this does not guarantee price appreciation, as SOL would still respond to broader market conditions, liquidity, and demand for Solana applications.

The impact on staking yields and validator profitability is a critical variable in this analysis. Faster disinflation would lower the nominal yield paid to SOL stakers, with the SIMD-0550 analysis modeling staking returns falling from approximately 5.84% to lower levels over time. These estimates assume that around 68% of SOL remains staked, and actual returns would also depend on validator commissions, transaction fees, and MEV income. For holders, a lower nominal reward would be partly offset by slower dilution, as earning fewer SOL has a different effect when the overall supply is also expanding more slowly.

However, validators face a more direct problem because their server, staffing, and infrastructure costs would not automatically decline with inflation. Among the 738 validators included in the proposal’s model, two could move from profitable or breakeven to unprofitable during the first year. That estimate rises to 13 after two years and 30 after three years, indicating that smaller validators relying heavily on inflation commissions could face greater pressure if transaction fees and MEV revenue do not replace enough of the lost rewards.

SGP-0003 remained in its support phase at the time of the latest governance snapshot, requiring validators representing at least 15% of total active stake to express support before the proposal can move into discussion and formal voting. Helius was the largest visible supporter, with approximately 16.03 million SOL, representing 3.70% of validator stake. Blueshift followed with approximately 3.6 million SOL, or 0.83%. Other visible supporters included Solana Compass, Temporal, Ha1iad3, Cavey Cool, and Harmonic Major.

This support is not a final vote to introduce the fee system; even if the proposal reaches the threshold and later receives majority approval, the vote would only endorse pursuing the model. Developers would still need to implement it, test it, and activate it through staged feature gates. SIMD-0550 remains under review and would need its own approval and implementation process before changing Solana’s inflation schedule, highlighting the complexity and length of the governance path ahead.

The future health of the network will depend on whether these proposals can successfully shift Solana’s reliance from newly issued tokens to real network activity. For the resource-based fee model, the most useful evidence will be the final fee rates, how accurately applications set their resource limits, and whether higher costs change transaction activity. Users should also watch whether wallets and applications update their fee estimates before activation, as poor estimates could cause transactions to reserve more capacity than necessary and pay higher fees.

For SIMD-0550, the important figures will be staking participation, inflation-adjusted returns, validator profitability, and whether transaction fees and MEV replace part of the lost issuance revenue. This marks a pivotal moment for Solana’s economic design, as the network attempts to balance sustainability with growth, aiming to reach the 1.5% inflation floor while maintaining a robust and profitable validator ecosystem.
