TL;DR
Priority fees are extra SOL paid to validators to prioritize your transaction, while Jito tips are payments to Jito block builders for guaranteed inclusion and optimal ordering in the next block.
Solana processes thousands of transactions per second, but during high-demand periods — token launches, liquidation events, or popular mints — the network gets congested. Base fees alone won’t guarantee your transaction lands in the next block. Priority fees let you bid for faster inclusion, which is critical when milliseconds determine whether you get a fill or miss out entirely.
Solana’s fee model has two components: a base fee (fixed at 5,000 lamports per signature) and a priority fee (variable, measured in micro-lamports per compute unit). Higher priority fees signal to the current block leader that your transaction should be processed first. Most trading bots and wallets let you configure this with a simple slider or input field.
Jito runs a modified Solana validator client that accepts “tip” payments from searchers and traders. Unlike standard priority fees that go through the regular fee market, Jito tips go directly to the block builder, who bundles your transaction with guaranteed ordering. This is essential for MEV strategies, snipes, and any trade where precise execution order matters. Jito tips are paid in SOL to a set of known tip accounts.
Overpaying wastes SOL; underpaying means your transaction drops. Most trading bots offer dynamic fee estimation based on current network conditions. For casual trades, 0.0001–0.001 SOL in priority fees is usually enough. For competitive snipes or launches, Jito tips of 0.01+ SOL may be needed. Tools listed on MadeOnSol often include built-in fee optimization to handle this automatically.
