Solana is evaluating two distinct changes to its token economics. One proposal would introduce a resource-based transaction fee model designed to burn more SOL, while the other would accelerate the decline of the network's inflation rate, reducing the number of new tokens issued to validators and stakers over time. Neither proposal is currently active on mainnet, and each is at a different stage of development, requiring separate governance, implementation, and activation processes. The changes come as several major Layer 1 blockchains have adjusted their token economics in recent years, with Ethereum's EIP-1559 upgrade in August 2021 being a prominent example of introducing fee burning to offset issuance.

Validators are currently gathering support for SGP-0003, which calls on the network to adopt the resource-based fee model described in SIMD-0553. Separately, SIMD-0550 proposes doubling the annual rate at which Solana's inflation decreases.

SIMD-0553: Charging Transactions by Resource Use

Solana currently charges a base fee of 5,000 lamports per signature. Half of that fee is burned, and the other half is paid to the validator producing the block. This flat charge does not account for how differently transactions consume network resources. A simple token transfer and a complex application requesting substantial computing capacity pay the same base fee, even though they place very different demands on validators.

The proposed model would split fees into two components. Priority fees would remain unchanged and continue to be paid to the block leader. The second component—a resource charge—would be calculated based on what a transaction requests before execution, not what it ultimately consumes. Efficient transactions could end up paying less than under the current flat system, while applications reserving large amounts of compute or account data could pay considerably more. Whereas Ethereum's EIP-1559 burns a dynamic base fee that adjusts with block congestion, Solana's proposed model would tie the burn to the specific compute and data resources a transaction reserves.

This structure would give developers an incentive to set accurate resource limits rather than relying on oversized default budgets. Wallets, RPC providers, and decentralized applications would need to update their fee estimates before activation. Without those updates, users could face unexpectedly high costs even when a program uses only a fraction of the capacity it requested.

The proposal also acknowledges a limitation in its earliest stage: very small spam transactions could initially face a lower minimum cost than under the current system. Later stages would raise the resource charge to address this.

Projected Burn Rates Under the Fee Model

According to the proposal, Solana currently burns approximately 648 SOL per day through the destroyed portion of its base transaction fee. Using network activity recorded in May 2026, the authors estimated that the resource fee could ultimately burn between 7,500 and 9,000 SOL per day. On an annual basis, that range equates to roughly 2.7 million to 3.3 million SOL.

These figures are estimates rather than a guaranteed burn schedule. They assume transaction activity and requested resource use remain broadly comparable to the May 2026 data used in the model. Higher network activity or more resource-intensive transactions would increase the burn, while developers reducing unnecessary compute requests could lower the per-transaction fee. Conversely, higher costs could discourage some activity and reduce the total fees generated. The model would thus tie Solana's burn rate more closely to actual demand for network resources.

SIMD-0550: Accelerating the Decline in SOL Issuance

Solana set its initial inflation rate at 8% when mainnet launched, with that rate declining by 15% each year until it reaches a long-term floor of 1.5%. SIMD-0550 proposes increasing that annual reduction rate to 30%.

The inflation rate would not be suddenly halved upon activation. Instead, it would continue from its existing level and then decline more quickly each year. Using an inflation rate of approximately 3.82% as of June 1, 2026, the proposal estimates that approximately 18.9 million fewer SOL would be created over six years, leaving total supply around 2.6% lower than under the current schedule. The long-term 1.5% target would remain unchanged, but Solana would reach it almost three years earlier.

This reduction does not remove 18.9 million SOL already in circulation. It represents tokens that would no longer be issued compared to the existing inflation path.

Impact on SOL Supply Dynamics

The two proposals would affect different aspects of Solana's supply growth. SIMD-0553 would destroy more existing SOL when transactions consume network resources, while SIMD-0550 would reduce the amount of new SOL distributed through staking rewards.

Lower issuance would reduce dilution for existing holders and could decrease one source of recurring market supply, as some validators and stakers sell rewards to cover infrastructure costs, taxes, or other expenses. However, not every newly issued token is sold—some rewards remain staked or held—so 18.9 million fewer tokens issued would not translate into an equivalent reduction in selling pressure.

The proposals would also fall well short of making SOL immediately deflationary. The fee model estimates that Solana currently issues approximately 60,000 SOL per day through inflation. Even the projected terminal burn of 7,500 to 9,000 SOL per day would initially remain far below that figure. Faster disinflation would gradually narrow the gap between issuance and burns, but 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 outcome is slower supply growth rather than a shrinking total supply.

Potential Price Implications

Burning more SOL and issuing fewer new tokens could improve the supply-demand balance if network usage and investor demand remain stable or grow. However, this does not guarantee price appreciation. SOL would continue to respond to broader market conditions, liquidity, demand for Solana applications, and whether either proposal is approved and implemented.

The burn estimate also depends on activity remaining strong. If higher fees reduce transaction demand, the amount of SOL destroyed could fall below the modeled range. The proposals are therefore more relevant to long-term dilution than to any immediate supply shortage.

Effects on Staking Rewards

Faster disinflation would lower the nominal yield paid to SOL stakers. The SIMD-0550 analysis models staking returns declining from approximately 5.84% to 4.34% after one year, 3% after two years, and 2.25% after three years. These estimates assume that around 68% of SOL remains staked. 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.

Validators face a more direct challenge because their server, staffing, and infrastructure costs would not automatically decline alongside 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. These are model projections rather than forecasts for individual operators, but they suggest that smaller validators relying heavily on inflation commissions could face greater pressure if transaction fees and MEV revenue do not sufficiently replace lost rewards. This dynamic could contribute to validator consolidation, even though Solana would eventually reach the same 1.5% inflation floor under either schedule. Similar concerns have been observed on other proof-of-stake networks where declining issuance tightened operator margins.

Governance Status and Next Steps

SGP-0003 remained in its support phase at the time of the latest governance snapshot. Validators representing at least 15% of total active stake must express support before the proposal can advance to 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 does not constitute 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, test, and activate it through staged feature gates.

SIMD-0550 remains under review and would require its own approval and implementation process before any changes to Solana's inflation schedule take effect. For both proposals, the milestones to watch are whether SGP-0003 clears the 15% stake threshold to enter formal voting, whether SIMD-0550 progresses from review to a formal governance vote, and whether either proposal advances to testnet deployment ahead of any mainnet activation.

Evaluating the Proposals After Approval

For the resource-based fee model, the most relevant metrics will be the final fee rates, how accurately applications set their resource limits, and whether higher costs alter transaction activity. Users should also monitor whether wallets and applications update their fee estimates before activation, as poor estimates could cause transactions to reserve more capacity than necessary and incur higher fees.

For SIMD-0550, the key figures will be staking participation, inflation-adjusted returns, validator profitability, and whether transaction fees and MEV revenue replace part of the lost issuance.

Together, the proposals would make Solana more dependent on real network activity and less reliant on newly issued tokens. That transition would be most effective if transaction demand remains strong enough to generate meaningful burns and sustain validators without making ordinary network use unnecessarily expensive.
