Functions

initialize

function initialize(struct StorageInstance app_) external

transfer

function transfer(address from, address to, uint256 value) external

Dev note

Moves a value amount of tokens from from to to.

This internal function is equivalent to {transfer}, and can be used to e.g. implement automatic token fees, slashing mechanisms, etc.

Emits a {Transfer} event.

NOTE: This function is not virtual, {_update} should be overridden instead.

update

function update(address from, address to, uint256 value) external

beforeTokenTransfer

function beforeTokenTransfer(address from, address to, uint256) public

afterTokenTransfer

Prevent gamesmanship by applying cooldown periods after unexecuted requests. After an expired request, the next one is given a cooldown period. But it would be easy to work around that by transfering shares to a fresh account to make a request with no penalty

So,

• Prevent transfering tokens "reserved" by an ongoing request
• If next request will receive a penalty, revert until best-case penalty would have finished

function afterTokenTransfer(address from, address to, uint256 amount) public

deposit

Deposit amount collateral to user, calling ERC-2612 permit() using the attached signature and deadline. See EIP-4626.

function deposit(
	uint256 amount,
	address user,
	uint256 deadline,
	struct IVaultDomain.Signature signature,
	Shares minShares
) public returns (
	Shares shares
)

Parameters

Name	Type	Description
amount	uint256	Collateral to deposit from msg.sender
user	address	Address credited with the deposit
deadline	uint256	deadline for permit
signature	struct IVaultDomain.Signature	permit entitling DomFiVault to amount collateral
minShares	Shares	Slippage control. Ignored if zero. If nonzero, revert if a deposit yields less than minShares

Return Values

Name	Type	Description
shares	Shares	dfUSDC amount sent to user in exchange for this collateral
