What is a Gas Limit?. A gas limit is the maximum amount of computation you allow a transaction to use. If execution exceeds the limit, it reverts.
How it works
Wallets estimate gas needs; complex contract calls require higher limits than simple transfers.
Why it matters
Choosing sensible limits prevents wasted fees and failed transactions.
Common pitfalls
- Setting limits too low on complex actions
- Blindly accepting estimates in unusual conditions
- Confusing gas price with gas limit
Quick example
You increase the gas limit for a multi‑step contract call while keeping the gas price modest.
