Crypto & Blockchain Tools

Crypto and blockchain tools for the two numbers that decide whether an on-chain activity is worth doing: what it costs and what it returns. The category covers mining profitability from hash rate, power draw, electricity price, and current network difficulty; trade profit and loss net of entry and exit fees; and transaction gas fees across Ethereum, Polygon, BSC, Arbitrum, Optimism, Avalanche, and Base, including the EIP-1559 base-fee-plus-tip model. Everything is an estimate from the inputs you supply, so the output is only as current as the price, hash rate, and gas figures you enter. The mistake that costs the most money is reading mining revenue as profit: a rig looks worthwhile at today's coin price until you subtract the electricity it burns around the clock and the next difficulty adjustment, both of which the mining tools here make you enter rather than assume. The second is treating a trade's headline gain as take-home while ignoring the fees on both sides, which the profit tools break out as their own line. If you are new to the category, start with the mining profitability tools before buying or running hardware, the profit tools to size a trade after fees, and the gas fee estimates before sending a transaction on a network where fees spike with congestion. None of these are live feeds or financial advice; confirm against a current block explorer or exchange before committing funds.
