# Developer Portal

## Vault (Hypervisor) Deposit

### Contracts

* UniProxy.sol →  Deposit proxy contract with information about deposit ratios.  All deposits must go thru UniProxy, not Hypervisor
* Hypervisor.sol →  Main vault manager contract with information about both base and limit liquidity ranges and amounts.  To withdraw, interact with the Hypervisor.

### Deposit

Functionally the source of any integration would require

#### 1. Getting the ratio of assets

UniProxy.getDepositAmount( lpTokenAddress, tokenProvidedAddress, tokenProvidedQuantity )

returns \[minQuanity, maxQuantity]

#### 2.  Deposting via the UniProxy →  UniProxy.deposit()

UniProxy.deposit( token0Quantity, token1Quantity, userAddress, lpTokenAddress )

### Withdrawal

Hypervisor.withdraw( lpTokenQuantityToBurn, destinationAddress, sourceAddress, \[0,0,0,0] )

(where "Hypervisor" is the lp token contract, destinationAddress is destination for redeemed token0, token1, sourceAddress is holder of the lp tokens, \[0,0,0,0] is a min-out constraint only used on L1)
