Solana's Fee Overhaul: Winners and Losers in the New Compute Unit Pricing
A new proposal for Solana's fee model is set to introduce a more granular system, which could have significant implications for major applications and routers on the network.
The SGP-0003 proposal, introduced alongside SIMD-0553 on August 3, 2026, would replace Solana's flat 5,000-lamport base fee with 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.
A simulation run by analyst @MostlyData_ found that under the new model, transactions would request significantly more compute units than they actually consume, resulting in higher fees for applications and routers that over-request CUs.
The simulation pegged average fee increases at roughly 0.000068 SOL for Jupiter, 0.00010 SOL for Titan, and 0.00012 SOL for DFlow.
