Ethereum Guides, Gas Fees and Wallet Resources
Use the SwapETH.org guides to understand Ethereum gas, gwei, transaction-fee mechanics and the practical checks that matter when sending or receiving native ETH. Live network data stays in the Ethereum Gas Tracker, while the articles below explain the underlying concepts and common transaction questions.
Ethereum Gas Guides
Start with the topic that matches the question you are trying to solve.
- What Is Ethereum Gas? — how Ethereum measures computational work, who pays gas and why different transactions use different amounts.
- What Is Gwei? — the ETH denomination used to express gas prices, including gwei-to-ETH examples.
- Ethereum Gas Limit vs Gas Price — the difference between gas limit, gas used, gas price, base fee, priority fee and max fee.
- How to Reduce Ethereum Gas Fees — practical ways to reduce unnecessary cost without relying on fixed "cheapest hour" claims.
- Why Ethereum Gas Fees Change — how block demand, EIP-1559 base-fee adjustment and transaction complexity affect Ethereum fees.
Check Current Ethereum Gas
Static articles should not be used to answer what gas costs right now. Current Low, Standard and Fast gwei values, a simple ETH-transfer fee estimate and recent 24H, 7D and 30D history belong to the live tool.

For wallet and asset questions rather than gas mechanics, use the practical pages:
- Native ETH vs WETH — understand the difference between Ethereum's native asset and its ERC-20 wrapped representation.
- How to Receive ETH — wallet-agnostic steps for receiving native ETH on Ethereum Mainnet.
- Ethereum Wallet Address —
0xformat, network checks, checksum context and common address mistakes.
Ethereum Swap Routes
If the goal is to exchange cryptocurrency rather than research Ethereum mechanics, use the dedicated pair page for the exact direction. SwapETH.org separates routes such as BTC → ETH and ETH → BTC because the source network, destination requirements and network fees differ by direction.
