GasFees.org is a research and tools website focused on on-chain transaction costs in crypto. It is not an exchange, wallet, or DeFi protocol; instead, it helps users understand and estimate gas fees before making transfers, approvals, swaps, bridges, NFT mints, or DeFi interactions. The site is currently being rebuilt, with an emphasis on search, readability, topic pages, chain pages, calculators, structured data, and a human-reviewed, AI-assisted publishing workflow.
The website covers Ethereum, Aptos, Base, Arbitrum, Solana, and Polygon, and also provides fee explanations for Layer 2/Rollup networks such as Linea, zkSync Era, and Mantle. Its Multichain Gas Fees Tracker uses the Etherscan API V2 gas oracle to display safe, average, and fast gas prices for supported EVM chains, and can estimate costs for scenarios such as a 21k transfer, 65k token transfer, 100k approve, 180k swap, and 300k complex DeFi transaction. The Aptos Gas Fee Calculator estimates fees based on assumptions such as instruction gas, storage gas, and payload size, while clearly stating that it is an educational model rather than a wallet quote.
The main content does not mention subscriptions, paywalls, or a commercial API, so it can currently be viewed as a free informational tool. Since it does not custody assets or handle trade matching, there is no mention of KYC, cold wallets, insurance, fiat deposits/withdrawals, derivatives, or leverage. On compliance, no licenses are disclosed; the terms of service page is still placeholder content and notes that affiliate, liability, and informational-only disclaimers need review, which means the legal documentation is still incomplete.
Its strengths are a focused topic scope, usefulness for quickly understanding fee models across different chains, and the ability to help compare cost differences caused by network congestion and transaction complexity before signing. It also reminds users to rely on their wallet’s final estimate, which is a prudent stance. The downsides are that the site is still migrating, with some images and legacy content yet to be cleaned up; real-time data depends on Etherscan and CoinGecko, so coverage and accuracy are limited by external data sources; and it lacks customer support, accounts, data SLAs, and complete legal terms.
It is suitable for everyday on-chain users, DeFi participants, and content researchers who want to estimate fees before transacting, especially when comparing costs across L2s, Rollups, and mainnet. It is not suitable for users who want to directly buy crypto, trade, deposit or withdraw fiat, or use leveraged products. The main content does not provide information about access from mainland China, and payments are not applicable. If it is inaccessible, alternatives include Etherscan Gas Tracker, L2Fees, DeFiLlama, or built-in gas estimates in wallets.
