Algorand Standard Assets are digital representations of assets on the Algorand blockchain. This is similar to how ERC-20 tokens and ERC-721 tokens represent different types of assets on Ethereum, except ASAs can represent any type of asset—both fungible and non-fungible, open and restricted. As well as cryptocurrencies, ASAs can represent in-game items, identities, government-issued fiat, collectables, and regulatory certifications.
