TokenLibrary

Author: Quantillon Labs - Nicolas Bellengé - @chewbaccoin

Library for essential token operations to reduce contract bytecode size

This library provides core token validation functions:

Mint and burn parameter validation with supply cap checks
Used by QEURO token for secure minting and burning operations

Note: security-contact: team@quantillon.money

Functions

validateMint

Validates mint parameters

Ensures minting doesn't exceed maximum supply and validates parameters

Notes:

security: Validates input parameters and enforces security checks
validation: Validates input parameters and business logic constraints
state-changes: Updates contract state variables
events: Emits relevant events for state changes
errors: Throws custom errors for invalid conditions
reentrancy: Protected by reentrancy guard
access: Restricted to authorized roles
oracle: Requires fresh oracle price data

function validateMint(address to, uint256 amount, uint256 totalSupply, uint256 maxSupply) internal pure;

Parameters

Name	Type	Description
`to`	`address`	Address to mint to
`amount`	`uint256`	Amount to mint
`totalSupply`	`uint256`	Current total supply
`maxSupply`	`uint256`	Maximum supply cap

validateBurn

Validates burn parameters

Ensures sufficient balance and validates parameters for burning

Notes:

security: Validates input parameters and enforces security checks
validation: Validates input parameters and business logic constraints
state-changes: Updates contract state variables
events: Emits relevant events for state changes
errors: Throws custom errors for invalid conditions
reentrancy: Protected by reentrancy guard
access: Restricted to authorized roles
oracle: Requires fresh oracle price data

function validateBurn(address from, uint256 amount, uint256 balance) internal pure;

Parameters

Name	Type	Description
`from`	`address`	Address to burn from
`amount`	`uint256`	Amount to burn
`balance`	`uint256`	Current balance
