The W3D Terminal is a free, open-source decentralization toolkit: fifteen calculators and explorers covering Nakamoto coefficients, validator profits, staking comparisons, gas estimation, address validation, seed-phrase checks, impermanent loss, L2 fees, bridge risk, multisig planning, airdrop readiness, token unlocks, live coefficient simulation, composite score radar, and a self-custody quiz. Every tool runs entirely in your browser — no wallet connection, no signup, no data sent anywhere, MIT licensed to fork.
Use it two ways: type commands into the interactive shell above (help lists everything, open nakamoto-coefficient loads a tool, chain btc shows live audit data), or open any tool as a full standalone page with its complete guide. Deep links like /terminal/?tool=gas-estimator-l2 take you straight to a tool; every chain page links here with its context preselected.
All figures on data pages come from the published methodology and the open dataset on GitHub. Static estimates (APRs, fee multipliers) are labeled illustrative wherever they appear — verify live network conditions before committing funds.
