Solana validators have begun signaling support for two proposals aimed at slowing SOL supply growth. SIMD-0550 would cut future issuance, while SIMD-0553 would increase burns based on the network resources each transaction requests.
Both proposals entered the support phase this week, which determines whether validators will trigger a full stake-weighted vote. Falling short would prevent an SGP vote but would not automatically end the underlying SIMD review.
SolanaFloor reported that SIMD-0550 needs 43.27 million SOL, or 10% of active stake, to advance and had 16.93 million SOL in early support. That proposal-specific gate sits below the 15% default published in Solana’s SGP rules, which SIMD-0553 is using.
🚨BREAKING: @Solana’s Double Disinflation proposal is now live in the support phase.
It needs 10% of active stake, or 43.27M $SOL, to advance to a full governance vote. It currently has 16.93M $SOL in support, reaching 39.1% of the threshold. pic.twitter.com/ptD7javQgB

Authored by Helius engineers Lostin and 0xIchigo, SIMD-0550 would raise Solana’s annual disinflation rate from 15% to 30% without changing the 1.5% terminal inflation rate.
The proposal estimates that Solana would reach that floor in about 2.8 years instead of 5.7 years. It would reduce emissions by roughly 18.9 million SOL over six years while leaving validator commission settings, transaction fees and maximal extractable value rules unchanged.

The narrower design follows SIMD-0228, a market-based inflation proposal that failed to win the required supermajority in March 2025. SIMD-0550 changes one parameter and preserves a predictable schedule.
SIMD-0553 would replace the current 5,000-lamport-per-signature charge with a flat 2,500-lamport inclusion fee per transaction for the block leader and a separate resource fee that is fully burned. The burn would reflect signature costs, write locks, instruction data, requested compute and loaded account data, with staged rates of 0.1, 0.25 and 0.5 lamports per cost unit. Priority fees would still go to validators.
Solana’s July 23 changelog said the technical proposal had been accepted, though its GitHub document still carried a Draft label as of August 4. The latest text says the mechanism can operate before or after Alpenglow, removing a dependency discussed in the earlier version.
The support launch cited a rise from roughly 650 SOL burned daily to as much as 9,000 SOL, close to a 14-fold increase. That figure is a projection because the burn depends on requested resources, network demand and which rate becomes active.
🚨JUST IN: @Solana’s Resource and Inclusion Fee proposal, which could raise estimated daily burns from 650 $SOL ($51K) to as much as 9K $SOL ($702K), is now live in the support phase. It needs backing from 15% of active stake to advance to a full governance vote. pic.twitter.com/kKpXo4Tfzs

Current issuance remains near 60,000 SOL per day. Even at 9,000 SOL burned, net issuance would remain around 51,000 SOL daily, meaning the fee change alone would not make SOL deflationary. SIMD-0553 had 24.94 million SOL in support as of August 4, with signaling scheduled to close on August 18.
