How Ethereum Gas Works
Gas Limitis the maximum number of computational units you're willing to pay for. Unused gas is refunded — you won't pay more than gas used × gas price, even if your limit is higher.
Gas Price (in Gwei) is your bid per unit. Higher bids get included in blocks faster. Post-EIP-1559, gas price = base fee (burned) + priority tip (to validator).
Fee formula: Fee = Gas Used × Gas Price — Gas Limit is the ceiling, not what you always pay.
⚠ Gas prices change constantly — always verify current values in your wallet or on Etherscan before submitting a transaction.
Common Gas Limits
| Transaction Type | Typical Gas Limit |
|---|---|
| ETH Transfer | 21,000 |
| ERC-20 Token Transfer | ~65,000 |
| Uniswap V3 Swap | ~150,000 |
| NFT Mint | ~200,000 |
| Contract Deployment | 500,000+ |
