Solana Fees Explained: Why Transactions Cost Less Than a Cent

If you have ever used Ethereum during a busy period, you know the pain of gas fees. A simple token swap might cost $20, $50, or even $100 when the network is congested. Then you try Solana and your transaction costs $0.00025. Less than a penny. Often less than a tenth of a penny.

How is this possible? Is Solana cutting corners on security? Are there hidden costs? Or is the network simply designed differently?

The answer lies in Solana's architecture. The same innovations that make Solana fast also make it cheap. In this guide, we will break down exactly how Solana fees work and why they stay so low.

Every Solana transaction includes two types of fees:

The base fee is fixed at 0.000005 SOL per signature. Most transactions require just one signature (yours), so this is what you typically pay. At a SOL price of $150, that works out to $0.00075 per transaction. At $100 per SOL, it is $0.0005.

This fee is hardcoded into the protocol. It does not fluctuate based on network demand like Ethereum's gas prices.

The priority fee is optional. You can add extra SOL to your transaction to increase your chances of faster inclusion when the network is busy. Think of it like tipping to get better service.

Unlike Ethereum, where priority fees can spike dramatically during congestion, Solana's priority fees remain modest because the network has so much capacity. Even during peak activity, adding a small priority fee in the range of 0.00002–0.00005 SOL is typically enough to improve inclusion without wasting money.

Solana's transaction fees consist of two components: a base fee (fixed at 5,000 lamports per signature) and an optional priority fee (added by users to expedite processing during congestion).

• For the base fee: 50% goes to the validator who processes your transaction (the current block leader), and 50% is burned (permanently removed from circulation).
• For the priority fee: 100% goes to the validator, with none burned.

The burn mechanism on the base fee creates deflationary pressure on SOL supply over time. As network usage increases, more SOL gets burned, which can help offset inflation from staking rewards. This structure, updated via SIMD-0096 in mid-2025, rewards validators more directly for handling high-priority transactions during periods of demand. Overall fee levels remain low, with averages around $0.017 per transaction as of early 2026, though they can spike during congestion.

Solana's low fees are a direct result of architectural decisions that maximize efficiency.

Most blockchains spend significant resources agreeing on the order of transactions. Validators must communicate back and forth to establish consensus on timing.

Solana's Proof of History (PoH) creates a cryptographic clock that timestamps transactions before they even reach consensus. This dramatically reduces the communication overhead between validators, making the entire process more efficient.

Less overhead means validators can process more transactions with the same resources, which means lower costs per transaction.

Ethereum processes transactions sequentially, one after another. If the network can handle 15 transactions per second, that is the ceiling regardless of how powerful the hardware becomes.

Solana's Sealevel runtime processes transactions in parallel. Because every transaction must declare which accounts it will read from and write to, the network knows which transactions can safely execute simultaneously. Non-conflicting transactions run at the same time across multiple CPU cores.

This parallel processing means Solana can handle thousands of transactions per second. When you spread fixed infrastructure costs across thousands of transactions instead of dozens, the cost per transaction drops dramatically.

On Ethereum, transactions sit in a mempool waiting to be picked up by validators. During congestion, users bid against each other with higher gas fees, creating an auction dynamic that drives prices up.

Solana uses Gulf Stream, which forwards transactions directly to the upcoming block leaders. There is no global mempool where transactions compete. The leader schedule is known in advance, so transactions route efficiently without the bidding war dynamic.

Running a validator has fixed costs: hardware, bandwidth, electricity, and maintenance. These costs exist whether the validator processes 100 transactions or 100,000 transactions per slot.

Solana's high throughput means these fixed costs are spread across far more transactions than on slower networks. The economics are similar to how a high-volume factory can sell products cheaper than a small workshop.

Numbers speak louder than explanations. Here is how Solana fees compare to other major blockchains:

The difference is not marginal. Solana transactions cost roughly 1,000 to 10,000 times less than Ethereum transactions for equivalent operations.

Low fees unlock use cases that are simply not viable on higher-fee networks.

On Ethereum, a $50 swap fee means you need significant position sizes to make trading worthwhile. On Solana, you can execute small trades, rebalance frequently, and implement strategies that would be eaten alive by fees elsewhere.

Minting an NFT on Ethereum might cost $20-$100 in gas. On Solana, you can mint for fractions of a penny. This enables experiments, iterations, and high-volume collections that would be prohibitively expensive elsewhere.

Blockchain games require frequent on-chain interactions. If every action costs $1, the game becomes unplayable for most users. Solana's sub-cent fees make in-game transactions invisible from a cost perspective.

Paying someone $0.10 does not work if the fee is $5. Solana's fee structure makes true micropayments viable, opening possibilities for content monetization, tipping, and pay-per-use services.

Yes, but the magnitude is completely different from other networks.

During extreme congestion events (like popular NFT mints or token launches), Solana fees can increase. However, "high" fees on Solana are negligible. The network's high capacity means even during peak demand, there is usually enough throughput to keep fees manageable.

Solana also implements local fee markets, where congestion in one application does not necessarily affect fees for unrelated transactions. If a popular NFT mint is clogging certain accounts, your simple token transfer to a different account can still go through at normal fees.

This advantage was evident during the market crash of October 10, 2025—the largest crypto liquidation event on record at the time. Solana performed seamlessly, processing approximately 100,000 transaction packets per second and sustaining 60 million compute units per block without any service degradation, while median transaction fees rose only to $0.007. In contrast, several Ethereum Layer 2 solutions reported latency issues, and median fees on Ethereum and Arbitrum spiked to $100.

You might wonder how validators make money if fees are so low. The answer is volume plus inflation rewards.

Validators earn from three sources:

1. Inflation rewards: Validators receive newly minted SOL for participating in consensus. This is currently the primary income source.
2. Transaction fees: 50% of base fees and 100% of priority fees go to block leaders. With millions of transactions daily, this adds up.
3. MEV (Maximal Extractable Value): Validators can earn additional revenue from transaction ordering through services like Jito.

The economics work because Solana processes enough transactions that even tiny per-transaction fees generate meaningful revenue at scale. Validators also pay fees themselves for voting transactions (approximately 1.1 SOL per day), which contributes to the burn mechanism.

Solana's fee structure is designed to remain low as the network scales. Several factors support this:

Continued performance improvements: Upgrades like Firedancer (a new validator client) and DoubleZero (a fiber optic cable, physical infrastructure project) are expected to increase throughput further, spreading fixed costs across even more transactions.

Local fee markets: As mentioned, congestion in one part of the network does not create global fee spikes.

No artificial scarcity: Unlike some networks that limit block space to drive up fees, Solana is designed to maximize throughput.

That said, if SOL price increases significantly, the dollar cost of transactions will rise proportionally since base fees are denominated in SOL. A 10x increase in SOL price would mean a 10x increase in dollar-denominated fees, though this would still leave Solana far cheaper than alternatives.

Solana fees are already minimal, but here are a few tips:

Batch transactions when possible: Some operations can be combined into a single transaction, requiring only one base fee instead of multiple.

Skip priority fees for non-urgent transactions: Unless you are in a time-sensitive situation, the base fee alone is usually sufficient.

Use efficient RPC providers: Quality RPC nodes route transactions more efficiently, reducing the chance of failed transactions (which still cost fees).

Solana's sub-cent transaction fees are not a temporary promotion or a compromise on security. They are the natural result of an architecture optimized for high throughput and efficiency.

The combination of Proof of History (reducing coordination overhead), Sealevel (enabling parallel processing), Gulf Stream (eliminating mempool bidding wars), and raw throughput (amortizing fixed costs) creates a fee structure that is fundamentally different from older blockchain designs.

For users, this means you can interact with Solana without constantly calculating whether a transaction is "worth" the fee. For developers, it opens possibilities for applications that simply would not work on higher-fee networks.

The next time you see a Solana transaction cost $0.00025, you will know exactly why.
