The Solana base fee is a fixed charge of 0.000005 SOL (5,000 lamports) applied per signature on every transaction. Unlike Ethereum's gas market where base fees fluctuate dramatically with network congestion, Solana's base fee is statically set at the protocol level — giving users a highly predictable cost structure.

‍

Why Is the Base Fee Fixed?

Solana's design philosophy prioritises accessibility and predictability. A fixed base fee means developers building on Solana can calculate transaction costs with certainty, and everyday users are never surprised by sudden fee spikes. This is one of the core differentiators between Solana and earlier-generation blockchains.

At a SOL price of $100, the base fee of 0.000005 SOL equals just $0.0005 — half a tenth of a cent.

Per-Signature, Not Per-Transaction

An important nuance: the base fee is charged per signature, not per transaction. Most standard transfers involve a single signature, so the cost is one base fee. However, some advanced transactions — like those involving multiple signers or authorisations — will have proportionally higher base fees. Wallets calculate this automatically and show you the total before you confirm.

How Is the Base Fee Distributed?

Fifty percent of each base fee collected is given to the validator who processed the transaction as a reward for their work maintaining network security. The remaining fifty percent is burned — permanently removed from the circulating SOL supply. This burning mechanism was introduced to add a deflationary element to Solana's tokenomics, benefiting all SOL holders over the long term.

Base Fee vs. Ethereum Gas Base Fee

On Ethereum, the base fee adjusts dynamically with each block based on supply and demand. During network congestion, Ethereum base fees have exceeded $50 per transaction. Solana's fixed 0.000005 SOL base fee remains constant regardless of network activity — making it approximately 100,000 times cheaper under normal conditions.
