Basically, ERC20 is a template or standard for a Smart Contract on the Ethereum Blockchain, which stores addresses and the corresponding account balances. In other words, the ERC20 token standard defines a list of basic functions and events that a token programmed on this standard must implement. The developers of the token can use the standardized program functions and make their tokens. If the source token is not ETH (ie. an ERC20 token), the user is required to first call the ERC20 approve function to give an allowance to the smart contract executing the transferFrom function. To prevent front running, the contract limits the gas price trade transactions can have. The transaction will be reverted if the limit is exceeded
