-Les descripteurs de wallet sont une méthode standardisée pour décrire les scripts que le wallet peut utiliser pour dépenser des bitcoins. Ils fournissent une manière compacte et compréhensible de représenter les scripts, incluant les informations sur le type d'adresse (par exemple, P2PKH, P2SH, P2WPKH, etc.), et les clés ou chemins de clés impliqués.

-
-Ici, `wpkh` signifie "witness public key hash" (SegWit), [clé_priveN/84'/M'/0'/0/n] est le chemin de dérivation avec `N` la référence à la clé privée, `M` est `1` pour signet custom (normalement 1 représenterait testnet, mais un signet custom peut avoir une convention différente) et `0` pour mainnet, `n` est l'index de l'adresse, et `xpubN` représente l'extended public key correspondant à la clé privée. Le `/0/*` à la fin indique que ce sont des adresses de réception (change addresses seraient `/1/*`).
-
-Ici, cprvN représente un placeholder pour le chemin de dérivation de chaque clé privée. Les clé_priveN sont des placeholders pour les clés privées réelles, et le reste de la structure reste comme expliqué précédemment.
-
-Ici il s'agit du format de stockage des privées, ce pourquoi la clé privée est indiquée dans le descripteur au lieu de la `xpub` plus classiquement utilisées pour ne pas exposer les clés privées.
