💡 How to Save on Gas Fees

⏰

Time Your Transactions

Ethereum fees are lowest on weekends and between midnight–4am UTC. Non-urgent transactions can save 50%+.

⚡

Use Layer 2 Networks

Arbitrum, Optimism, and Base offer 99%+ fee savings vs Ethereum mainnet with the same security guarantees.

🔗

Batch Transactions

Combine multiple actions into one transaction using multisig wallets or DeFi routers to pay gas once.

🎚

Set Custom Gas Limits

For non-urgent transfers, set the slow/economy gas tier in your wallet. Saves 30-50% vs auto-pricing.

Ethereum Gas FAQ

What is Ethereum gas?

Gas is the unit that measures the computational effort required to execute operations on the Ethereum network. Every transaction requires gas to compensate validators for processing it.

Why do gas fees fluctuate?

Gas fees go up when network demand is high (many transactions competing for block space) and down when demand is low. The base fee adjusts automatically every block via EIP-1559.

What is Gwei?

Gwei (gigawei) is a denomination of ETH. 1 Gwei = 0.000000001 ETH (1 billionth of ETH). Gas prices are quoted in Gwei because they're small fractions of ETH.

What's the cheapest blockchain for transactions?

Solana has the lowest fees at around $0.0001 per transaction. Among EVM-compatible chains, Base and Optimism are among the cheapest at $0.001–$0.05 per transaction.

When are Ethereum gas fees lowest?

Ethereum gas is typically cheapest on weekends and during UTC late-night hours (00:00–06:00). Major market events and NFT mints drive fees up significantly.
