## Creating ERC-20 tokens

Within the Ethereum blockchain, we can record transactions and run smart contracts. These things allow us to run DApps (decentralized applications) and which can support the running of the infrastructure in return for some payment (Ether). A DApp can also create tokens for new currencies, shares in a company or to prove the ownership of an asset. ERC-20 is a standard format for a Fungible Token and which can support the sharing, transfer and storage of tokens. These tokens are supported by the whole of the Ethereum infrastructure and can be easily traded. They support a number of mandatory functions:

# Additional Tutorial
|
||||
At the end of this lab, remember to stop your Blockchain (Control-C from the console that is running Geth), and shut down your VM. You may also want to use “rm -r mynapier” in order to delete your blockchain.
