NATIVE_TOKEN_ADDRESS ​
address that is mapped to the chain native token at Liquidity
function NATIVE_TOKEN_ADDRESS() external view returns (address);depositNative ​
deposits msg.value amount of native token for receiver_. msg.value must be at least minDeposit() amount; reverts otherwise. Recommended to use depositNative() with a minAmountOut_ param instead to set acceptable limit.
function depositNative(address receiver_) external payable returns (uint256 shares_);Returns
| Name | Type | Description |
|---|---|---|
shares_ | uint256 | actually minted shares |
depositNative ​
same as depositNative but with an additional setting for minimum output amount. reverts with fToken__MinAmountOut() if minAmountOut_ of shares is not reached
function depositNative(address receiver_, uint256 minAmountOut_) external payable returns (uint256 shares_);mintNative ​
mints shares_ for receiver_, paying with underlying native token. shares_ must at least be minMint() amount; reverts otherwise. shares_ set to type(uint256).max not supported. Note there might be tiny inaccuracies between requested shares_ and actually received shares amount. Recommended to use depositNative() over mint because it is more gas efficient and less likely to revert. Recommended to use mintNative() with a minAmountOut_ param instead to set acceptable limit.
function mintNative(uint256 shares_, address receiver_) external payable returns (uint256 assets_);Returns
| Name | Type | Description |
|---|---|---|
assets_ | uint256 | deposited assets amount |
mintNative ​
same as mintNative but with an additional setting for minimum output amount. reverts with fToken__MaxAmount() if maxAssets_ of assets is surpassed to mint shares_.
function mintNative(uint256 shares_, address receiver_, uint256 maxAssets_)
external
payable
returns (uint256 assets_);withdrawNative ​
withdraws assets_ amount in native underlying to receiver_, burning shares of owner_. If assets_ equals uint256.max then the whole fToken balance of owner_ is withdrawn.This does not consider withdrawal limit at liquidity so best to check with maxWithdraw() before. Note there might be tiny inaccuracies between requested assets_ and actually received assets amount. Recommended to use withdrawNative() with a maxSharesBurn_ param instead to set acceptable limit.
function withdrawNative(uint256 assets_, address receiver_, address owner_) external returns (uint256 shares_);Returns
| Name | Type | Description |
|---|---|---|
shares_ | uint256 | burned shares |
withdrawNative ​
same as withdrawNative but with an additional setting for minimum output amount. reverts with fToken__MaxAmount() if maxSharesBurn_ of shares burned is surpassed.
function withdrawNative(uint256 assets_, address receiver_, address owner_, uint256 maxSharesBurn_)
external
returns (uint256 shares_);redeemNative ​
redeems shares_ to native underlying to receiver_, burning shares of owner_. If shares_ equals uint256.max then the whole balance of owner_ is withdrawn.This does not consider withdrawal limit at liquidity so best to check with maxRedeem() before. Recommended to use withdrawNative() over redeem because it is more gas efficient and can set specific amount. Recommended to use redeemNative() with a minAmountOut_ param instead to set acceptable limit.
function redeemNative(uint256 shares_, address receiver_, address owner_) external returns (uint256 assets_);Returns
| Name | Type | Description |
|---|---|---|
assets_ | uint256 | withdrawn assets amount |
redeemNative ​
same as redeemNative but with an additional setting for minimum output amount. reverts with fToken__MinAmountOut() if minAmountOut_ of assets is not reached.
function redeemNative(uint256 shares_, address receiver_, address owner_, uint256 minAmountOut_)
external
returns (uint256 assets_);withdrawWithSignatureNative ​
withdraw amount of assets_ in native token with ERC-2612 permit signature for fToken approval. owner_ signs ERC-2612 permit signature_ to give allowance of fTokens to msg.sender. Note there might be tiny inaccuracies between requested assets_ and actually received assets amount. allowance via signature should cover previewWithdraw(assets_) plus a little buffer to avoid revert. Inherent trust assumption that msg.sender will set receiver_ and minAmountOut_ as owner_ intends (which is always the case when giving allowance to some spender).
function withdrawWithSignatureNative(
uint256 sharesToPermit_,
uint256 assets_,
address receiver_,
address owner_,
uint256 maxSharesBurn_,
uint256 deadline_,
bytes calldata signature_
) external returns (uint256 shares_);Parameters
| Name | Type | Description |
|---|---|---|
sharesToPermit_ | uint256 | shares amount to use for EIP2612 permit(). Should cover previewWithdraw(assets_) + small buffer. |
assets_ | uint256 | amount of assets to withdraw |
receiver_ | address | receiver of withdrawn assets |
owner_ | address | owner to withdraw from (must be signature signer) |
maxSharesBurn_ | uint256 | maximum accepted amount of shares burned |
deadline_ | uint256 | deadline for signature validity |
signature_ | bytes | packed signature of signing the EIP712 hash for ERC-2612 permit |
Returns
| Name | Type | Description |
|---|---|---|
shares_ | uint256 | burned shares amount |
redeemWithSignatureNative ​
redeem amount of shares_ as native token with ERC-2612 permit signature for fToken approval. owner_ signs ERC-2612 permit signature_ to give allowance of fTokens to msg.sender. Note there might be tiny inaccuracies between requested shares_ to redeem and actually burned shares. allowance via signature must cover shares_ plus a tiny buffer. Inherent trust assumption that msg.sender will set receiver_ and minAmountOut_ as owner_ intends (which is always the case when giving allowance to some spender). Recommended to use withdrawNative() over redeem because it is more gas efficient and can set specific amount.
