This tool generates random BIP39 seed words for cryptocurrency wallets. It uses various entropy sources to ensure secure randomness.
This page generates random numbers and BIP39 words for a seedphrase using user input or external entropy sources (e.g., Swatch .beats, Block Data, HTTP Latency, Bxl Rail Traffic, LavaRand, Dice Roll, ANU Quantum RNG). Randomness is influenced by Light/Dark mode (jump calculation), salt level, and the chosen entropy source. For best use, run locally for basic, secure functionality (offline), or online with all external sources enabled for maximum entropy.

Randomizer 3000 generates secure BIP39 seed words (up to 23) for cryptocurrency wallets using diverse entropy sources: user input, Swatch .beats, Bitcoin block data, HTTP latency, local randomness, transit traffic (Brussels trains based on time), LavaRand, dice rolls, or ANU Quantum RNG (quantum-based randomness from the Australian National University). Users can generate one word or a full set, with randomness adjusted by light/dark mode jumps and optional salt levels. It supports online (external APIs) or offline (local entropy) modes, displays results with logs, and offers safe copying and checksum links. The Seed Entropy Factor (SEF) is calculated for each word, with a final report combining average SEF, source diversity (via Shannon Entropy Formula, measuring unpredictability), and an overall score, averaged into a human-readable rating from 'terrible' to 'perfection'.
