I'm studying the BIP39 and the seed phrase. I can read this doc (https://en.bitcoin.it/wiki/BIP_0039) and I can find Created: 2013-09-10. In bitcoin talk I can read this article (https://bitcointalk.org/index.php?topic=19137) with date June 18, 2011

I can find this post about Electrum release, https://bitcointalk.org/index.php?topic=100502.0 but i'ts just a seed not a seedphrase (or I mistake about it?)

So When did the first Wallet (and which one) implement the BIP39? Or when the user started to use it to store his keys?

    The bitcointalk post you link to was the original idea for deterministic wallets. It was adopted in the Armory wallet, and later a (different) scheme was standardized as BIP32 (disclaimer: I'm the author). BIP39 came even later and proposed replacing BIP32's seed key with a seed phrase. I don't know which wallets first implemented BIP32 or BIP39, but I wanted to make it clear that currently adopted standards had several independent components, developed by different people, spread over several years.

  • thanks @PieterWuille. So we could say that the Seed phrase came from 2013-09-10, and we could say that after that date a wallet could implement it. I mean the 2013-sept-10 is the release of that. My questoin is, what is the first software wallet adopted the BIP39? in which date?
