allowance(owner: address, spender: address)
view
Returns the remaining token allowance that owner granted to spender.✨ AI
dev: 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.
Parameters
| Name | Type | Description |
|---|---|---|
| owner | address | Address that owns the tokens.✨ AI |
| spender | address | Address allowed to spend the owner's tokens.✨ AI |
Returns
| Name | Type | Description |
|---|---|---|
| — | 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
dev: Returns the amount of tokens owned by `account`.
Parameters
| Name | Type | Description |
|---|---|---|
| account | address | Address whose LUSD token balance is returned.✨ AI |
Returns
| Name | Type | Description |
|---|---|---|
| — | 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
Returns
| Name | Type | Description |
|---|---|---|
| — | address | Address of the BorrowerOperations contract associated with the LUSDToken.✨ AI |
decimals()
view
→ 18
Return the number of decimal places the token uses.✨ AI
Returns
| Name | Type | Description |
|---|---|---|
| — | 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
Returns
| Name | Type | Description |
|---|---|---|
| — | bytes32 | The EIP-712 domain separator (bytes32) used to construct and verify typed signatures such as permits.✨ AI |
name()
view
→ LUSD Stablecoin
Returns the ERC-20 token's human-readable name.✨ AI
Returns
| Name | Type | Description |
|---|---|---|
| — | 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
dev: 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.

| owner | address | Address whose nonce is queried.✨ AI |
Returns
| Name | Type | Description |
|---|---|---|
| — | uint256 | Current uint256 nonce for the owner, used to ensure each permit/signature is unique.✨ AI |

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
dev: 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.
Parameters
| Name | Type | Description |
|---|---|---|
| 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 |
Returns
| Name | Type | Description |
|---|---|---|
| — | bool | True if the allowance was successfully set.✨ AI |
burn(_account: address, _amount: uint256)
nonpayable

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
dev: 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].
Parameters
