Try EntropyLab online with test data. See how entropy becomes a seed phrase, keys and addresses. 🎲

For real seeds, download the HTML and run it on a fully offline computer. Never enter a real seed in the online version.

@hodl_puck We're aiming for a v1.0.0 release by next week. Then we'll spend the next couple of weeks doing more testing and audits before presenting it at Tabconf.

Who’d be interested in a limited-edition “Seed Round” of EntropyLab merch to help fund our clankers for the next few weeks/months?

I’m thinking a small run of a few different items...just 21 of each, individually numbered and tastefully branded with the EntropyLab logo.

Each piece would be marked:

Seed Round · x/21

Ooga boogas + giga brains have been cooking. The amount of useful stuff being added is mind blowing.

First tool that gives you BIP39 words and a Bitcoin Core wallet.dat already loaded with the descriptors... from the same air-gapped session!

First practical way to inspect a hardware wallet PSBT for nonce reuse without touching a key.

One HTML file. Bring your own entropy. It never generates it.

Hold and receive without a hardware or software wallets. Sign later.

EntropyLab is an air-gapped Bitcoin calculator. One HTML file. You bring the entropy. It never rolls dice for you.

You do not need a hardware wallet or a software wallet to hold or receive bitcoin. A signing device is only for spending.

What it does:

• Dice rolls, coin flips, hex, or binary → seed
• Three dice methods: hash the rolls, BitBox-style, Ian Coleman / Keystone
• Seed phrase, xprv/xpub, WIF, hex key, Casascius minikey
• Optional passphrase
• BIP39 seed, Bitcoin Core key, xpubs, fingerprints, descriptors
• Legacy, nested SegWit, native SegWit, Taproot
• Mainnet and testnet
• Watch-only multisig (m-of-n from xpubs, no private keys)
• Recovery sheet you can save or print
•

PSBT inspect: where it sends, amounts, fee, signed or not

• ECDSA nonce reuse check (save `r`, compare next spend)

• Optional RFC 6979 check with a key that stays in RAM for that session only

Download the file. Open it on a machine that never goes online. Don’t type a real seed on a computer that’s connected.
