The Vault is the main account for a token pair and granularity. The Vault account is a PDA composed of the following seeds:

seeds = [
    b"drip-v1".as_ref(),
    token_a_mint.key().as_ref(),
    token_b_mint.key().as_ref(),
    vault_proto_config.key().as_ref(),
],

The Vault combined with the Vault Period is responsible for making sure that user funds are kept track of correctly on deposits and withdraws. The Vault also performs the the Drips in every period.
