SIMD-0553 would split Solana’s current 5,000-lamport per-signature fee into a 2,500-lamport inclusion fee paid to leaders and a new requested_cost_units x 0.5 lamport resource fee that is fully burned. The draft estimates the new burn at roughly 7,500-9,000 SOL/day versus about 648 SOL/day today, still well below roughly 60,000 SOL/day inflation. It shifts costs toward high-resource, low-priority traffic like zero-prio Pump.fun swaps, while votes and low-resource oracle updates can get slightly cheaper.
