Vault

Inherits: ERC4626, Multicall, AccessControlDefaultAdminRules, ReentrancyGuard

Author: Molecular Labs

Vault contract that can allocate a single lender asset over various isolated lending pairs on Ion Protocol. This contract is a fork of the Metamorpho contract licnesed under GPL-2.0 with changes to administrative logic, underlying data structures, and lending interactions to be made compatible with Ion Protocol.

addSupportedMarkets

Add markets that can be supplied and withdrawn from.

    internal;

removeSupportedMarkets

Removes a supported market and updates the supply and withdraw queues without the removed market.

The allocationCap values of the markets being removed are automatically deleted. Whenever a market is removed, the queues must be updated without the removed market.

_validateQueueInput

*The input array contains ordered IonPools.

Must not contain duplicates.
Must be the same length as the supportedMarkets array.
Must not contain indices that are out of bounds of the supportedMarkets EnumerableSet's underlying array. The above rule enforces that the queue must have all and only the elements in the supportedMarkets set.*

reallocate

Reallocates the base asset supply position across the specified IonPools. This call will revert if the resulting allocation in an IonPool violates the pool's supply cap.

*Depending on the order of deposits and withdrawals to and from markets, the function could revert if there is not enough assets withdrawn to deposit later in the loop. A key invariant is that the total assets withdrawn should be equal to the total assets supplied. Otherwise, revert.

Negative value indicates a withdrawal.
Positive value indicates a supply.*

function accrueFee() external onlyRole(OWNER_ROLE) returns (uint256 newTotalAssets);

_supplyToIonPool

Iterates through the supply queue to deposit the desired amount of assets. Reverts if the deposit amount cannot be filled due to the allocation cap or the supply cap.

External functions calling this must be non-reentrant in case the underlying IonPool implements callback logic.

function _supplyToIonPool(uint256 assets) internal;

Parameters

`assets`	`uint256`	The amount of assets that will attempt to be supplied.

assets

uint256

The amount of assets that will attempt to be supplied.

External functions calling this must be non-reentrant in case the underlying IonPool implements callback logic.

function _withdrawFromIonPool(uint256 assets) internal;

Parameters

Name Type Description

Name	Type	Description
`assets`	`uint256`	The desired amount of assets to be withdrawn.

assets

uint256

The desired amount of assets to be withdrawn.

deposit

Transfers the specified amount of assets from the sender, supplies into the underlying IonPool markets, and mints a corresponding amount of shares.

All incoming deposits are deposited in the order specified in the deposit queue.

function deposit(uint256 assets, address receiver) public override nonReentrant returns (uint256 shares);

Parameters

Name Type Description

Name	Type	Description
`assets`	`uint256`	Amount of tokens to be deposited.
`receiver`	`address`	The address to receive the minted shares.

assets

uint256

Amount of tokens to be deposited.

receiver

address

The address to receive the minted shares.

mint

Mints the specified amount of shares and deposits a corresponding amount of assets.

Converts the shares to assets and iterates through the deposit queue to allocate the deposit across the supported markets.

function mint(uint256 shares, address receiver) public override nonReentrant returns (uint256 assets);

Parameters

Name Type Description

Name	Type	Description
`shares`	`uint256`	The exact amount of shares to be minted.
`receiver`	`address`	The address to receive the minted shares.

shares

uint256

The exact amount of shares to be minted.

receiver

address

The address to receive the minted shares.

withdraw

Withdraws specified amount of assets from IonPools and sends them to the receiver in exchange for burning the owner's vault shares.

All withdraws are withdrawn in the order specified in the withdraw queue. The owner needs to approve the caller to spend their shares.

function withdraw(
    uint256 assets,
    address receiver,
    address owner
)
    public
    override
    nonReentrant
    returns (uint256 shares);

Parameters

Name Type Description

Name	Type	Description
`assets`	`uint256`	The exact amount of assets to be transferred out.
`receiver`	`address`	The receiver of the assets transferred.
`owner`	`address`	The owner of the vault shares.

assets

uint256

The exact amount of assets to be transferred out.

receiver

address

The receiver of the assets transferred.

owner

address

The owner of the vault shares.

redeem

Redeems the exact amount of shares and receives a corresponding amount of assets.

After withdrawing assets, the user gets exact assets out. But in the IonPool, the resulting total underlying claim may have decreased by a bit above the assets amount due to rounding in the pool's favor. In that case, the resulting totalAssets() will be smaller than just the newTotalAssets - assets. Predicting the exact resulting totalAssets() requires knowing how much liquidity is being withdrawn from each pool, which is not possible to know until the actual iteration on the withdraw queue. So we acknowledge the dust difference here. If the lastTotalAssets is slightly greater than the actual totalAssets, the impact will be that the calculated interest accrued during fee distribution will be slightly less than the true value.

function redeem(
    uint256 shares,
    address receiver,
    address owner
)
    public
    override
    nonReentrant
    returns (uint256 assets);
