# Vault Proto Config

The `VaultProtoConfig` stores the common configuration for a set of vaults such as fee information, the drip granularity, and the admin that can deploy new vaults using this config. 

```rust
pub struct VaultProtoConfig {
    pub granularity: u64, // 8
    // spread applied to each drip trigger in bps
    pub token_a_drip_trigger_spread: u16, // 2
    // spread applied to each withdrawal in bps
    pub token_b_withdrawal_spread: u16, // 2
    // spread applied to each withdrawal in bps
    pub token_b_referral_spread: u16, //2
    // to be used with the vault to modify certain fields (whitelist)
    pub admin: Pubkey, //32
}
```
