What Is a Priority Fee on Solana? Meaning in Crypto
Priority fee: A priority fee is an optional extra fee added to a transaction so validators process it sooner; on Solana it goes fully to the validator.
Key takeaways
- A priority fee is an optional extra fee that makes validators more likely to include your transaction sooner.
- On Solana, the base fee is 5,000 lamports per signature, and 100% of the priority fee goes to the validator, according to Solana's docs.
- Memecoin bots let you set the priority fee; Axiom's default is 0.001 SOL, and a higher fee helps in busy launches but adds cost to every trade.
What a priority fee means
A priority fee is an extra fee that you add to a transaction so validators include it sooner. It is optional, but in a busy memecoin launch a trade without it can land late or fail.
How it works
Solana's fee docs set a base fee of 5,000 lamports per signature. The priority fee comes on top: the compute unit price in micro-lamports times the compute unit limit, divided by 1,000,000. Half of the base fee is burned, but 100% of the priority fee goes to the validator.
Example: a token goes viral and thousands of wallets try to buy it in the same minute. You set a 0.001 SOL priority fee in your bot. A trader who pays 0.005 SOL has a better chance to land in an earlier slot and buy at a lower price. Axiom uses 0.001 SOL as its default priority fee.
Why it matters for traders
- Cost: you pay the priority fee on every trade, win or lose. On small trades it can be a large share of the cost. Our fee calculator shows the total.
- Speed: sniping and fast exits need a higher fee.
- Not protection: a priority fee speeds you up but does not stop a sandwich attack. For that, bots use MEV protection, often with a Jito tip.
