Solana Validators Weigh 14x Increase in SOL Burns
Key Takeaways
- •SIMD-0553 proposes replacing Solana's flat base fee with a fixed inclusion fee of 2,500 lamports per transaction and a separate variable resource fee that would be fully burned.
- •The resource-based fee model could eventually raise daily SOL burns from approximately 648 to between 7,500 and 9,000 SOL at the terminal stage, though these figures are projections subject to network conditions.
- •SIMD-0550 would increase Solana's annual disinflation rate from 15% to 30%, enabling the network to reach its 1.5% inflation floor by 2029 rather than 2032.
- •Even at the highest projected burn rates, SOL would not become deflationary because the network still issues roughly 60,000 SOL per day at its current inflation rate of about 3.8%.
- •Validator support for the fee proposal currently stands at 5.8% of staked SOL across sixteen validators, well short of the 15% threshold needed to advance to a formal vote.
Solana validators are reviewing two separate proposals that would change SOL supply growth, with one focused on transaction fees and the other on the network's inflation schedule. Neither proposal has reached mainnet approval. Both are being tracked as Solana Improvement Documents, the formal mechanism for proposing protocol changes on the network.
The first proposal, SIMD-0553, would alter transaction fees through a resource-based model. The second, SIMD-0550, would accelerate the decline in SOL inflation. Each proposal would proceed through its own governance, development, and activation process.
Solana Validators Review Resource-Based Fees
Validators are gathering support for SGP-0003, which asks the network to pursue the fee model described in SIMD-0553. The proposal would replace Solana's current flat base fee with a fixed inclusion charge and a separate resource fee, an approach that echoes fee-burning mechanisms adopted on other major blockchains. Ethereum introduced base-fee burning through EIP-1559 in 2021, a change widely cited in discussions of sustainable token economics.
Under the proposal, the inclusion fee would cost 2,500 lamports per transaction and would go to the block leader. The resource fee would vary according to requested compute power, account data, and other network resources. Solana would burn that portion in full, while priority fees would still go to validators.
Projected SOL Burns Could Rise Sharply
Solana currently burns about 648 SOL per day from base transaction fees. Based on May 2026 activity, the proposal's authors estimate the new model could increase daily burns to between 1,500 and 1,800 SOL in an initial stage.
Later stages could push burns to between 3,750 and 4,500 SOL per day. At the terminal stage, the range rises to 7,500 to 9,000 SOL per day, equal to about 2.7 million to 3.3 million SOL annually.
Those figures are projections. Final burn levels could change depending on network usage, transaction size, developer settings, and fee sensitivity. Higher fees could also reduce some activity.
Faster Inflation Cuts Remain Separate
SIMD-0550 would raise Solana's annual disinflation rate from 15% to 30%. The network's long-term inflation floor would remain at 1.5%, but Solana could reach that level in 2029 instead of 2032.
The proposal estimates that Solana would issue about 18.9 million fewer SOL over six years. That figure represents tokens that would not enter supply under the faster schedule, not a removal of existing SOL.
Solana's inflation rate is currently near 3.8%. The network still issues about 60,000 SOL per day, meaning even a 9,000 SOL daily burn would not make SOL deflationary.
Support Remains Below Voting Threshold
Initial support for the proposal stands at 24.94 million SOL, or 5.8% of the 432.65 million SOL staked. The proposal needs 15% support before it can advance to a formal vote.
Sixteen validators have signaled support. Helius accounts for 16.03 million SOL, followed by Blueshift with 3.6 million and Temporal Emerald with 1.24 million.
If approved, the two proposals could slow Solana's supply growth. In the near term, the effect would likely be lower dilution rather than a shrinking total supply.
