A simulation of Solana's proposed SGP-0003 fee overhaul shows daily SOL burns could jump as high as 9,000 SOL, up from roughly 648 SOL now. The new dual-fee structure would raise costs most for routers like Jupiter, Titan and DFlow, while cutting fees for optimized vote transactions.
A live simulation of Solana's proposed SGP-0003 fee change shows daily SOL burns could rise from around 648 SOL to between 1,500 and 9,000 SOL, a jump of up to roughly 14 times. Analyst @MostlyData_ ran the simulation to quantify how the proposal would reshape transaction costs across Solana, and the results show clear winners and losers among the network's biggest applications.
What SGP-0003 changes
The governance proposal, introduced on August 3, 2026, alongside SIMD-0553, would retire Solana's flat 5,000-lamport base fee. In its place would come a two-part system: a fixed 2,500-lamport inclusion fee paid to the block leader, plus a variable resource fee starting at 0.1 lamports per requested compute unit that gets burned entirely.
On average, transactions request about 20% more compute units than they actually consume, and that overestimation costs nothing extra under the current flat-fee system. Under SGP-0003, however, it costs real money.
Routers absorb the biggest increases
That mismatch hits routers and aggregators hardest. The simulation pegged average fee increases at roughly 0.000068 SOL for Jupiter, 0.00010 SOL for Titan, and 0.00012 SOL for DFlow. Only about 28% of transactions would see a fee increase below 10% if resource pricing accurately reflects consumption.
Validators, though, come out ahead. Optimized vote transactions could become approximately 12.3% cheaper under the new model.
A parallel push to tighten supply
SGP-0003 was introduced alongside a separate measure to double Solana's disinflation rate from 15% to 30%, meaning the network would simultaneously increase token burns and accelerate the reduction of new token issuance. Central limit order book market makers face an especially interesting calculus here: they submit high volumes of compute-heavy transactions, so even small per-transaction fee increases compound quickly into material cost changes. Routers like Jupiter already dominate Solana's DeFi transaction flow. A fee increase, even a modest one per swap, could ripple through to end users or compress margins for aggregator protocols.
