Last one for today -- sorry for the overload, I had meant to post as the series kicked off... This post covers building various vaults/better cold storage using sapio https://rubin.io/bitcoin/2021/12/07/advent-10/. In an earlier post I motivated why self-custody is so critical (see https://rubin.io/bitcoin/2021/11/30/advent-3/); this post demonstrates how Sapio + CTV can dramatically enhance what users can do. Cheers, you'll see me in the inbox tomorrow, Jeremy -- @JeremyRubin
