Solana's Fee Model Overhaul: Winners and Losers in Store

Solana's upcoming fee model overhaul is set to introduce a more granular pricing system, but not all applications will benefit from it. A recent simulation by analyst @MostlyData_ reveals that the proposed SGP-0003 would lead to increased transaction costs across the network.

Under the current flat-fee system, transactions request about 20% more compute units than they actually consume, costing nothing extra. However, under SGP-0003, this overestimation will incur real costs, with routers and aggregators taking the biggest hit.

The simulation projects 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.
