This smart contract implements the ERC20 token standard and the EIP-2612 permit function. It allows users to transfer tokens, approve token transfers, and perform token allowances. It also supports token minting and burning.

The WETH contract is an ERC20 token that represents wrapped Ether. It allows users to deposit Ether and receive an equivalent amount of WETH tokens. Users can also withdraw WETH tokens and receive the corresponding amount of Ether. The contract uses the SafeTransferLib for secure transfers and emits events for deposits and withdrawals.

This smart contract is an extension of the ERC20 standard. It allows users to deposit and withdraw assets, mint and redeem shares, and perform accounting calculations. It also includes hooks for additional logic before withdrawals and after deposits.

This smart contract library allows for the deployment of contracts to deterministic addresses using CREATE2 opcode, enabling the creation of contracts without an initcode factor. It provides functions to deploy contracts with a specified salt, creation code, and value, and retrieves the deployed contract's address based on the salt.

This contract implements the ERC1155 standard for multi-token contracts. It allows for the transfer and management of multiple token types, including batch transfers and approvals. It also includes metadata logic for retrieving token URIs.

This contract implements ownership functionality, allowing the transfer of ownership to a new address. The owner can transfer ownership to another address, and only the owner can execute certain functions.

The ReentrancyGuard contract prevents reentrancy attacks by locking the contract during execution of a function. It ensures that the function can only be called once at a time, preventing recursive calls that could exploit vulnerabilities.

The MockERC20 contract is an ERC20 token implementation that allows minting and burning of tokens. It inherits from the ERC20 contract and provides functions to mint and burn tokens for a given address.

This contract is a library that provides safe transfer functions for both ETH and ERC20 tokens. It handles missing return values gracefully and ensures the success of the transfers.

This contract is a mock implementation of the ERC1155 standard. It provides functions to mint and burn tokens, as well as retrieve the URI for a given token ID.

This contract is a mock implementation of the ERC721 standard. It allows for minting and burning of tokens, as well as safe minting with optional data. The tokenURI function is not implemented.

This contract implements the ERC721 standard for non-fungible tokens (NFTs). It allows for token ownership, transfers, approvals, and metadata storage. It also includes functions for safe transfers and supports the ERC165 interface for contract compatibility.
