Vault is a Permissions, Chat, & Economy API to give plugins easy hooks into these systems without needing to hook or depend on each individual plugin themselves. It was born out of a distaste for how both Register and the current Permissions API are run, and their lack of features or over- complicated implementations. Vault attempts to solve these issues by being intuitive and providing plugins with support for any system that they may use.
