Gas Limit
Gas limit is the maximum amount of computational work you're willing to pay for in a blockchain transaction. It acts as a safety cap, preventing transactions from consuming unlimited resources. If a transaction needs more gas than the limit, it fails but still costs fees.
Understanding the Concept
• Set too low: transaction fails (out of gas error) • Set too high: only uses what's needed, excess is refunded • Complex smart contract interactions require higher gas limits • Simple transfers need less gas than DeFi transactions
Real-World Example
A simple ETH transfer needs about 21,000 gas. A Uniswap swap might need 150,000+ gas. If you set your gas limit to 50,000 for a swap, the transaction fails partway through, and you lose the gas used up to that point. Most wallets estimate the right limit automatically.
