About this tool

GasNow is a free, open-source tracker of what it actually costs to move crypto. It measures 12 networks every 10 minutes (Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Solana, Tron, TON, Bitcoin and Litecoin) and shows the cost to send the native coin, send USDT/USDC and swap, side by side. It also tracks withdrawal fees per network at Binance, KuCoin, Bitget, HTX and other exchanges, quotes the cheapest bridge routes between chains and keeps daily gas history. For developers there is a free gas API with no key, compatible with the discontinued Blocknative and gasnow.org A
