Solana validators are weighing two proposals that would overhaul the network's token economics, with a preliminary vote set for Aug. 3.
The first, SIMD-0553, would increase the daily SOL burn rate 14-fold—from roughly 650 coins to as many as 9,000. The mechanism: resource-based transaction fees levied across the network, priced to reflect actual demand and usage rather than a flat fee structure.
The second, SIMD-0550, would accelerate Solana's disinflation schedule, targeting a terminal inflation rate of 1.5 percent by 2029. Under the current schedule, that floor arrives later. Doubling the disinflation rate compresses the timeline and shrinks the runway of new SOL entering circulation.
Together, the two proposals hit supply from both ends—more coins burned per day, fewer new coins issued. For holders with active positions, that dynamic tightens net supply faster than the protocol's existing roadmap.
Solana was trading at $74.18 at the time of publication.
The resource-based fee model in SIMD-0553 also targets spam. By pricing compute resources closer to their true cost, the proposal aims to make low-value transaction flooding economically unworkable.
Separately, the Agave v4.2 mainnet activation is scheduled for Aug. 17, 2026. The client upgrade cuts slot times to 200 milliseconds—half the current target—increasing throughput and reducing latency for DeFi and other on-chain applications.
Validators will determine the outcome of both SIMD proposals. If either clears the initial vote, it advances toward full ratification. The Agave v4.2 upgrade proceeds on its own track regardless of the governance vote results.
