Solana Base Fee – The 5,000 Lamport Foundation
Every Solana transaction pays a base fee regardless of complexity or network conditions. This base fee is currently set at 5,000 lamports per signature in the transaction. Since 1 SOL equals 1,000,000,000 lamports, the base fee for a single-signature transaction is 0.000005 SOL — less than $0.001 at any SOL price below $200.
The base fee primarily compensates validators for the cryptographic work of verifying Ed25519 signatures. Unlike priority fees, which fluctuate with demand, the base fee is deterministic: you can always predict the exact base fee cost of any transaction by counting its signatures.
Base Fee Distribution – 50% Burned, 50% to Validators
Solana's base fee has a unique deflationary mechanism. Of every base fee collected, 50% is permanently burned (removed from circulating supply) and 50% is paid to the block-producing validator. This burn mechanism was designed to offset Solana's annual staking inflation and create a sustainable tokenomics model as network usage grows.

Key facts about Solana's base fee structure every developer and user should understand.
- Base fee = 5,000 lamports × number of signatures (including precompile verifications)
- Charged whether the transaction succeeds or fails
- 50% burned via DEFAULT_BURN_PERCENT mechanism in the runtime
- 50% paid to the block-producing validator as reward
Multiple Signatures and Fee Scaling
While most simple transactions have a single signature, complex transactions involving multiple signers or precompile programs (such as secp256k1 or ed25519 precompile for batch signature verification) incur higher base fees. The total base fee scales linearly: a transaction with three signatures pays 15,000 lamports in base fees, regardless of how complex the instructions are.
Developers building multi-sig wallets, cross-program invocations, or applications using precompile programs should account for this when estimating user costs. FeeSol's fee calculator helps you quickly compute the exact base fee for any signature count.
