One week old today. What EntropyLab already did: • Dice, coins, cards, hex, or binary → seed • Dice methods: hash the rolls, BitBox-style, Ian Coleman / Keystone, D++ D8/D16 • Live die-fairness check while you enter rolls • Seed phrase, xprv/xpub, WIF, hex key, Casascius minikey • Optional passphrase • All five BIP39 lengths: 12, 15, 18, 21, 24 • BIP39 seed, xpubs, fingerprints, descriptors, Bitcoin Core wallet.dat export • LifeHash next to each fingerprint so two keys are not easy to mix up • Legacy, nested SegWit, native SegWit, Taproot • Mainnet and testnet • Watch-only multisig from xpubs. No private keys required • Recovery sheet you can save or print • PSBT inspect: where it sends, amounts, fee, signed or not • Same inspector accepts a fully signed raw transaction • Labels outputs as change, receive, or not in this wallet when a session key is loaded • Finds inscription envelopes in tap-leaf scripts and witnesses (`OP_FALSE OP_IF "ord"`). Reports content-type, size, and a text preview. It does not number sats, fetch the chain, create inscriptions, or render images. • ECDSA nonce reuse check • Optional RFC 6979 check with a key that stays in RAM for that session only • Jade anti-exfil transcript check without a key What we added in the last two days: • BIP-85 child entropy from the parent you supply. Same parent, application, and index always reproduce the same child. Matches COLDCARD. Calculator, not a generator. • Silent Payments (BIP-352): reusable `sp1q` / `tsp1q` addresses, labeled codes, BIP-392 `spscan` / `spspend` descriptors, sender taproot outputs from pasted vin JSON, receiver check of pasted x-only outputs. It does not connect to a node or scan the chain. • Decodes OP_RETURN size and a text/hex preview. It does not create OP_RETURN outputs. • All Bitcoin math now runs on rust-bitcoin in WASM. Same library family Bitcoin Core uses. The HTML no longer ships a JS crypto stack. It still does not generate entropy. • Real PSBT editor. Open a PSBT, see every field, change a field, export only if rust-bitcoin accepts the file. It does not sign. It does not go online. • Pick the derivation scheme instead of hoping the tool guessed BIP84. BIP44 / 49 / 84 / 86 / 48, or type the path yourself. • PSBT inspect now reads Taproot script-path spends, UR crypto-psbt payloads, BitBox anti-klepto transcripts (not Jade), and reused Schnorr nonces. Reused nonce is the alarm. RFC 6979 mismatch is not. • Taproot multisig starts on BIP87, the co-signer account standard — not BIP86. A pasted BIP87 xpub no longer silently flips you to legacy P2SH. • After it is done with a seed or key, it wipes those buffers. Strings in the page are still strings. Download the file. Verify it. Open it on a machine that never goes online. This tool is for a Bitcoin power user which was only possible because of token maxen. #OogaBooga#
