Solana validators began signaling support this week for a governance proposal carrying two changes to how much $SOL enters and leaves circulation.
SIMD-0553 introduces resource-based fees, charging transactions according to the network resources they consume. That would lift daily burns from around 650 $SOL, about $47,000 at current prices, to between 7,500 and 9,000, or up to roughly $650,000 a day.
SIMD-0550 doubles the annual disinflation rate to 30%, which pulls Solana's 1.5% terminal inflation floor forward to 2029 from 2032 and removes about 18.9 million $SOL of emissions over six years, worth roughly $1.36 billion.
SIMD stands for Solana Improvement Document, the technical proposal process core developers use for protocol changes. SGP is Solana Governance Proposal, the newer stake-weighted vote that sits above it.
The two proposals impact supply from both ends, burning more of what exists while issuing less of what is new. Solana's inflation rate currently sits near 3.8%, down from an 8% start under a schedule that cuts 15% a year.
Initial support stands at 24.94 million $SOL, or 5.8% of the 432.65 million staked, roughly 38% of the way to the 15% threshold a proposal must clear before it reaches an actual vote. That leaves 39.95 million $SOL to find, or about $2.9 billion, before signaling closes on Aug. 18.
Sixteen validators have signaled so far, 2.3% of the set. Helius accounts for 16.03 million $SOL of the running total on its own, close to two-thirds of everything gathered, with Blueshift next at 3.6 million and Temporal Emerald at 1.24 million before the list thins out.
As such, the burn increase is smaller than it sounds against what Solana issues. Even at the top of the projected range, 9,000 $SOL a day sits against roughly 60,000 $SOL of daily inflation, so the fee change alone does not turn $SOL deflationary. That is part of why the two proposals travel together, with SIMD-0550 cutting issuance while SIMD-0553 raises what gets destroyed.
Meanwhile, Helius, which supplied 16.03 million $SOL of the 24.94 million gathered, employs the engineer behind SIMD-0550.
But the 15% gate exists precisely to test this. Solana Foundation set it in July so the validator set would only vote on questions enough stake actually cares about, leaving routine technical work inside the SIMD process.
