Web3j

Web3j est une bibliothèque Java et Android conçue pour intégrer des applications avec des clients blockchain Ethereum. Elle fournit un client JSON-RPC pour lire les données de la chaîne et soumettre des transactions, un générateur de wrapper de smart contract qui crée du code Java natif à partir de définitions de contrats, et un gestionnaire de portefeuille programmatique pour manipuler les clés cryptographiques et signer les transactions.

Le projet se distingue par un système de génération de wrapper basé sur des templates qui permet une interaction typée avec les contrats on-chain. Il inclut également un ensemble d'outils dédié pour traduire les noms de domaine lisibles par l'humain en adresses cryptographiques via la résolution de service de noms.

La bibliothèque couvre un large éventail de capacités, notamment l'exécution asynchrone pour les requêtes blockchain, la gestion des clés cryptographiques et le débogage de l'exécution de machine virtuelle pour analyser le comportement des contrats. Elle fournit en outre un modèle de connexion basé sur des fournisseurs pour abstraire le transport réseau et des outils en ligne de commande pour l'amorçage de projet.
