Solana’s ‘Double Disinflation’ Vote Passes by a Hair After Dramatic Finish

Solana validators approved the network’s first binding governance vote by a razor margin. Late switches decided it. The measure doubles the pace at which SOL issuance shrinks.

The “Double Disinflation” SIMD proposal pushes the protocol’s disinflation rate from 15% to 30%. Inflation now hits its 1.5% floor in 2029, three years ahead of the old schedule. The practical upshot: roughly 18.9 million fewer SOL minted than the prior trajectory promised. Validators and stakers get less. The token’s supply schedule tightens.

This was a first. Solana handed its economic dials directly to validators and let them vote. The timing tracks a wave of institutional money moving toward SOL. Charles Schwab plans to list SOL through its Schwab Crypto brokerage. The Bitwise Solana ETF has crossed $1 billion in assets under management, Decrypt reported.

Staking yield takes a direct hit. Decrypt puts the current rate near 5.25%, with a projected drop to around 2.25% within three years. Under the old schedule, those higher yields would have persisted longer. That is the change. Smaller validators face the sharpest squeeze. Issuance is what pays them, and there will be less of it.

The margin was thin. Validators linked to Kraken and Galaxy flipped positions as the clock ran out. Exact tallies were not disclosed in the sources reviewed. By the time the vote window shut, the outcome was locked.

A fee-burning measure on the same ballot produced a murkier result. One Decrypt account says it failed. A later Decrypt newsletter says all three proposals on the ballot passed. Neither source resolved the contradiction at press time. The fee-burn design, as described, splits each transaction fee into a base portion that still pays validators and a resource fee tied to compute consumed that gets destroyed. Daily burns would climb from roughly 650 SOL, worth about $48,000, to as much as 9,000 SOL, worth about $668,000.

The Solana Company (Nasdaq: HSDT), a treasury firm that backed the governance process itself, voted no on both economic proposals. Its argument: institutional stakers need predictable yield more than a faster cut. DeFi Development Corp (DFDV) went the opposite direction on all three measures. Then it bought 19,000 SOL for $1.86 million at an average of $105.14, bringing its treasury to roughly 2.33 million SOL. DFDV shares climbed 16% on the day. They have doubled in a month. They still sit about 90% below their May 2025 high.

SOL traded at $106, up 2% on the day per Decrypt market data. August was its strongest month since 2024, with a gain of roughly 44%. Whether the move traces to the vote, the tightening supply schedule, the coming Schwab listing, or treasury firms buying for the first time in ten months, Decrypt’s analysis credits all of the above. That reading skips the macro backdrop. Federal Reserve Chair Jerome Powell delivered dovish signals at Jackson Hole the same week.

The vote is a governance result. It is not yet a code change. Implementation follows the standard Solana upgrade process, with validators folding the new parameters into subsequent protocol releases. No date has been set.

For a network whose tokenomics ran on a fixed schedule since launch, the binding vote is the bigger shift. The cut passed. The fee burn did not, or did, depending on which Decrypt filing you read. Traders, as ever, disagree.
