The following smart contract is the AnyswapV5ERC20 contract, which implements the IAnyswapV3ERC20 interface. It is used for creating ERC20 tokens that can be deposited and withdrawn from a vault. The contract includes functions for minting and burning tokens, as well as swapping tokens in and out of the contract. It also includes functions for approving and transferring tokens, and for setting and changing the vault and minter addresses. The contract uses the SafeERC20 library for safe token transfers and the EIP712 standard for permit functions.
