Keys, Xpubs, 1Sat Ordinals, And Signed Metadata

A LiveView lab driven by the local bsv-ex repo. The story moves across the page as the demo shifts from key generation to watch-only derivation, custom scripts, ordinal envelopes, and MAP plus AIP.

Keys Mnemonic, Seed, And Account Key

Start with a deterministic mnemonic, derive an account xprv, then strip it to an xpub you can share without exposing spend authority.

Controls

Change the derivation branch, focus index, inscription body, and MAP fields. The page keeps the mnemonic fixed so the narrative stays reproducible.

Mnemonic, Seed, And Account Key

The deterministic seed is long, but the important transition is mnemonic to seed to account xpub.

Elixir

live snippet

mnemonic = "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about"
seed = BSV.Mnemonic.to_seed(mnemonic)
master = BSV.ExtKey.from_seed!(seed)
account = BSV.ExtKey.derive(master, "m/44'/236'/0'")
xpub = account |> BSV.ExtKey.to_public() |> BSV.ExtKey.to_string()

Seed Hex

This lab exposes full demo keys because the mnemonic is the public abandon … about test vector — anyone can derive them. Treat it as an explainer, not a wallet, and never send funds to these addresses.
