Ask for gas fees right now and get every supported chain side by side: base fee, slow / standard / fast priority tiers, the USD cost of a transfer, ERC-20 transfer, swap, NFT mint and contract deployment, trend and congestion, and which chain is cheapest at this moment. Estimate any transaction from gas or compute units, or rank chains by deployment cost for a given bytecode size. Live from public RPCs, read-only. Tools: • gas_now — Current fees on Ethereum, Base, Arbitrum, Robinhood Chain and Solana: base fee, slow/standard/fast tiers, USD cost per transaction type, trend and the cheapest chain. • estimate_tx_cost — Cost of one transaction on a chain at a speed tier, by transaction type (transfer, erc20_transfer, swap, nft_mint, deploy) or explicit gas / compute units. • cheapest_chain_to_deploy — Rank Ethereum, Base, Arbitrum, Robinhood Chain and Solana by the cost of deploying a contract or program of a given bytecode size. Targets questions like: “ethereum gas fees now”; “gas price today”; “base gas fee”; “arbitrum gas fees”; “solana priority fee”; “cheapest chain to deploy smart contract”.
