allowance(owner: address, spender: address) view

Returns the remaining token allowance that owner granted to spender.✨ AI

开发者： Returns the remaining number of tokens that `spender` will be allowed to spend on behalf of `owner` through {transferFrom}. This is zero by default. This value changes when {approve} or {transferFrom} are called.

参数

名称 类型 描述
owner address Address that owns the tokens.✨ AI
spender address Address allowed to spend the owner's tokens.✨ AI

返回值

名称 类型 描述
— uint256 Remaining number of tokens spender is allowed to transfer from owner.✨ AI
balanceOf(account: address) view

Returns the LUSD token balance of the given address.✨ AI

开发者： Returns the amount of tokens owned by `account`.

参数

名称 类型 描述
account address Address whose LUSD token balance is returned.✨ AI

返回值

名称 类型 描述
— uint256 The token balance of the account in the token's smallest unit (uint256).✨ AI
borrowerOperationsAddress() view → 0x24179cd81c9e782a4096035f7ec97fb8b783e007

Returns the current BorrowerOperations contract address used by this token.✨ AI

返回值

名称 类型 描述
— address Address of the BorrowerOperations contract associated with the LUSDToken.✨ AI
decimals() view → 18

Return the number of decimal places the token uses.✨ AI

返回值

名称 类型 描述
— uint8 Number of decimals (uint8) the token uses for display and arithmetic✨ AI
domainSeparator() view → 0xf85dbb1e9a5845cbb7605972678082c839c02db2df0e2e2eb4977e9744bbcd89

Return the contract's EIP-712 domain separator used to verify typed signatures.✨ AI

name() view → LUSD Stablecoin

Returns the ERC-20 token's human-readable name.✨ AI

返回值

名称 类型 描述
— string The token's human-readable name string (e.g., "LUSD").✨ AI
nonces(owner: address) view

Returns the current nonce for an owner used to validate off-chain permit signatures.✨ AI

开发者： Returns the current ERC2612 nonce for `owner`. This value must be included whenever a signature is generated for {permit}. Every successful call to {permit} increases `owner`'s nonce by one. This prevents a signature from being used multiple times. `owner` can limit the time a Permit is valid for by setting `deadline` to a value in the near future. The deadline argument can be set to uint(-1) to create Permits that effectively never expire.

参数

名称 类型 描述
owner address Address whose nonce is queried.✨ AI

返回值

名称 类型 描述
— uint256 Current uint256 nonce for the owner, used to ensure each permit/signature is unique.✨ AI
permitTypeHash() view → 0x6e71edae12b1b97f4d1f60370fef10105fa2faae0126114a169c64845d6126c9

Returns the EIP-712 permit type hash used to build the permit signature digest.✨ AI

返回值

名称 类型 描述
— bytes32 The keccak256 type hash (bytes32) for the permit struct as used in EIP-712 signing and verification.✨ AI
stabilityPoolAddress() view → 0x66017d22b0f8556afdd19fc67041899eb65a21bb

Returns the address of the Stability Pool associated with this LUSD token.✨ AI

返回值

— address The TroveManager contract address used for trove management, liquidation, and collateral tracking.✨ AI
version() view → 1

Returns the token contract's version string.✨ AI

返回值

名称 类型 描述
— string The contract version or release identifier (human-readable string).✨ AI

写入函数

approve(spender: address, amount: uint256) nonpayable

Set the caller's allowance for spender to amount, enabling the spender to transfer up to that many tokens.✨ AI

开发者： Sets `amount` as the allowance of `spender` over the caller's tokens. Returns a boolean value indicating whether the operation succeeded. IMPORTANT: Beware that changing an allowance with this method brings the risk that someone may use both the old and the new allowance by unfortunate transaction ordering. One possible solution to mitigate this race condition is to first reduce the spender's allowance to 0 and set the desired value afterwards: https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729 Emits an {Approval} event.

参数

名称 类型 描述
spender address Address authorized to spend tokens from the caller's balance.✨ AI
amount uint256 Maximum number of tokens the spender is permitted to transfer.✨ AI

返回值

名称 类型 描述
— bool True if the allowance was successfully set.✨ AI
burn(_account: address, _amount: uint256) nonpayable

Burns tokens from an account, reducing the token balance and total supply.✨ AI

参数

名称 类型 描述
_account address Address whose tokens will be burned.✨ AI
_amount uint256 Number of tokens to burn, in the token's smallest unit.✨ AI
decreaseAllowance(spender: address, subtractedValue: uint256) nonpayable

Decrease the allowance previously granted to a spender by a specified amount.✨ AI

参数

名称 类型 描述
spender address Address that is allowed to spend tokens on behalf of the caller.✨ AI
subtractedValue uint256 Amount to subtract from the current allowance for the spender.✨ AI

返回值

名称 类型 描述
— bool True if the allowance was decreased successfully.✨ AI
increaseAllowance(spender: address, addedValue: uint256) nonpayable

Increase the caller's token allowance for a specified spender by the given amount.✨ AI

参数

名称 类型 描述
spender address Address that will be allowed to spend the caller's tokens.✨ AI
addedValue uint256 Amount to add to the existing allowance for the spender.✨ AI

返回值

名称 类型 描述
— bool True if the allowance was increased successfully, otherwise false.✨ AI
mint(_account: address, _amount: uint256) nonpayable

Mints new LUSD tokens and assigns them to the specified account.✨ AI

参数

名称 类型 描述
_account address Address that will receive the newly minted tokens.✨ AI
_amount uint256 Amount of tokens to mint, expressed in the token's smallest unit.✨ AI
permit(owner: address, spender: address, amount: uint256, deadline: uint256, v: uint8, r: bytes32, s: bytes32) nonpayable

Permit lets an owner approve a spender using an off-chain signature so no separate on-chain approve call is needed.✨ AI

开发者： Sets `amount` as the allowance of `spender` over `owner`'s tokens, given `owner`'s signed approval. IMPORTANT: The same issues {IERC20-approve} has related to transaction ordering also apply here. Emits an {Approval} event. Requirements: - `owner` cannot be the zero address. - `spender` cannot be the zero address. - `deadline` must be a timestamp in the future. - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner` over the EIP712-formatted function arguments. - the signature must use ``owner``'s current nonce (see {nonces}). For more information on the signature format, see the https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP section].

参数

名称 类型 描述
owner address Address granting the approval.✨ AI
spender address Address receiving the allowance.✨ AI
amount uint256 Amount of tokens to allow.✨ AI
deadline uint256 Unix timestamp when the signature expires.✨ AI

Transfer tokens from sender to recipient using the caller's allowance.✨ AI

开发者： Moves `amount` tokens from `sender` to `recipient` using the allowance mechanism. `amount` is then deducted from the caller's allowance. Returns a boolean value indicating whether the operation succeeded. Emits a {Transfer} event.
