Solana validators have begun signaling support for a monetary-policy package built around SIMD-0550 and SIMD-0553, two proposals that would reduce new SOL issuance while increasing transaction-fee burns. The proposals address supply growth from opposite directions, but neither change is active: SIMD-0550 remains under review, while SIMD-0553 is still classified as a draft.
A recent signaling snapshot placed support at 24.94 million SOL, or about 5.8% of active stake, with Helius accounting for 16.03 million SOL. The package still needs roughly 40 million additional SOL to reach the 15% threshold required to advance, while the signaling period is scheduled to close on August 18.
Resource-Based Fees Would Increase SOL Burns
SIMD-0553 would replace the burned half of Solana’s existing 5,000-lamport signature fee with a resource fee calculated from the computing, account-locking and data resources requested by each transaction. The new resource component would be burned in full, while a fixed 2,500-lamport inclusion fee and priority fees would continue going to the block-producing validator.
The proposal uses three staged fee rates. Based on May network activity, its authors estimate resource-fee burns of 1,500–1,800 SOL per day at the first stage, 3,750–4,500 SOL at the second and 7,500–9,000 SOL at the final rate. That compares with approximately 648 SOL burned daily under the current structure, while inflation creates roughly 60,000 SOL per day.
The model would not raise every transaction’s cost equally. Lightweight transactions could pay less than today, while compute-heavy transactions with oversized resource requests could face substantially higher charges. SIMD-0553 is designed to price network consumption rather than impose a uniform fee increase, giving applications an incentive to estimate their resource requirements more accurately.
Double Disinflation Would Bring the 1.5% Floor Forward
SIMD-0550 would double Solana’s annual disinflation rate from 15% to 30% without changing the network’s long-term inflation floor of 1.5%. The proposal would move the expected arrival at terminal inflation from the first half of 2032 to the first half of 2029, according to modeling published by its authors.
The faster schedule is projected to prevent approximately 18.9 million SOL in emissions over six years, leaving total supply about 2.6% below the current path. Lower issuance would also reduce nominal staking yields more quickly, creating a trade-off between slower dilution and the revenue available to validators and delegators.
Even if both changes are adopted, Solana would not immediately become deflationary under the proposals’ assumptions. The highest projected burn remains well below daily issuance, and both documents require consensus-compatible software changes before activation. The current process is an early governance signal, not a confirmed monetary-policy update.
The package’s immediate significance lies in the direction of the debate: validators are being asked to support more usage-linked burns and a faster decline in inflationary rewards. Its final impact will depend on whether signaling reaches the required threshold, a formal vote passes and validator clients implement the changes consistently.
