Solana is advancing a structural reform of its fee model through the proposal SIMD-0553, an improvement document that would modify the way the protocol charges for computational resource usage. The proposal raises fees on resource-intensive transactions while lowering costs for simple operations.

The initiative was presented by Cavey, a researcher at Temporal, a Solana network infrastructure firm. It entered the network's new onchain governance process in early August and cleared its initial support phase on the 4th of that month. It is currently in the support and discussion stage, which lasts approximately two weeks.

The baseline diagnosis is stark: today, a transaction that does nothing costs the same as one that consumes 200 million CPU cycles. Because every Solana transaction draws on a shared per-block compute budget, that flat pricing treats the network's scarcest resource — CPU capacity — as if it were free. That distortion discourages efficiency and benefits those who waste resources without bearing their real cost.

Waste Has a Price

Under the proposed scheme, fees would be calculated based on the resources each transaction requests, rather than a uniform fixed amount. Revenue from that concept would not go to validators; it would instead be burned, removing $SOL from circulation. The design follows an approach Ethereum adopted with EIP-1559 in August 2021, which burns the protocol's base fee rather than paying it out to validators.

The model takes particular aim at computationally inefficient arbitrage. Over the past 30 days, the five traders with the highest failure rates sent 11.5 million transactions, consumed 929 million compute units across 2,477 operations that generated $16,091 in profits, and paid just 78 $SOL in fees. Bot activity of this kind became a visible strain on Solana during the memecoin trading surge of early 2024, when transaction failure rates spiked and congestion degraded the experience for ordinary users.

Simple operations would become cheaper under the new pricing. Stablecoin and token transfers could cost around 20% less, while vote transactions would drop 12.3% and oracle updates 16.9%, according to Temporal's modeling.

Some high-frequency swaps, by contrast, would face considerable increases: a medium-priority swap on OKX would cost 301% more, and a no-priority swap on pump.fun 3,150% more. Even so, Cavey argues that even the most resource-intensive transactions would hover around $0.05 — compared with the $2 or $5 a $100 swap can cost on a centralized exchange.

The Debate Over Validators

The most controversial point is the reduction in income for Solana validators, who would initially see their base revenue fall by around 4%. Validator economics on Solana combine fee revenue with staking rewards drawn from the network's inflation issuance, which is why redirecting fee income toward the burn is a sensitive trade-off. One contributor questioned whether the additional burn is a valid objective and argued that validator income should not be reduced arbitrarily.

On the burning side, the proposal projects that the daily figure would scale from 648 $SOL to between 7,500 and 9,000 $SOL — a 12 to 14 times increase over current levels. Given that the network emits approximately 60,000 $SOL per day, that level would still not make Solana deflationary on its own, although a parallel proposal, SIMD-0550, seeks to reduce inflation faster than previously planned.

The immediate milestone to watch is the close of the roughly two-week discussion window, after which the proposal would move toward a vote under the same onchain governance process; if approved, the new pricing would still need to ship in validator client releases before taking effect on mainnet.

For Cavey, the central objective is not deflation but rather aligning core, application, and infrastructure developers around more efficient use of the network.
