What is a Gas Fee?. A gas fee is what you pay to have your transaction processed and recorded on a blockchain. It compensates validators or miners for computation and storage.
How it works
Users set a fee or priority. When demand is high, fees rise to ration block space; low demand means cheaper inclusion.
Why it matters
Understanding fees prevents failed transactions and helps you choose the right time and network for an action.
Common pitfalls
- Submitting with too little gas, causing a revert
- Confusing token transfer fees with base‑layer gas
- Not checking current network conditions
Quick example
You schedule a token swap during low‑traffic hours and cap your maximum slippage to avoid surprise costs.
