implements fTokens support for deposit / mint via EIP-2612 permit.

methods revert if underlying asset does not support EIP-2612.

Functions

depositWithSignatureEIP2612

deposit assets_ amount with EIP-2612 Permit2 signature for underlying asset approval. IMPORTANT: This will revert if the underlying asset() does not support EIP-2612. reverts with fToken__MinAmountOut() if minAmountOut_ of shares is not reached. assets_ must at least be minDeposit() amount; reverts fToken__DepositInsignificant() if not.

function depositWithSignatureEIP2612(
    uint256 assets_,
    address receiver_,
    uint256 minAmountOut_,
    uint256 deadline_,
    bytes calldata signature_
) external returns (uint256 shares_);

Parameters

Returns

mintWithSignatureEIP2612

mint amount of shares_ with EIP-2612 Permit signature for underlying asset approval. IMPORTANT: This will revert if the underlying asset() does not support EIP-2612. Signature should approve a little bit more than expected assets amount (previewMint()) to avoid reverts. shares_ must at least be minMint() amount; reverts with fToken__DepositInsignificant() if not. Note there might be tiny inaccuracies between requested shares_ and actually received shares amount. Recommended to use deposit() over mint because it is more gas efficient and less likely to revert.

function mintWithSignatureEIP2612(
    uint256 shares_,
    address receiver_,
    uint256 maxAssets_,
    uint256 deadline_,
    bytes calldata signature_
) external returns (uint256 assets_);
