Aptos Standards
Standards define a common interoperable interface for all developers to build upon. They consist of rules to ensure compatibility across applications and wallets on the Aptos blockchain. See a list of known coin resource addresses in Aptos provided by hippospace.

Digital Asset Standards
Aptos Coin
The Coin module is a lightweight standard meant for simple, typesafe, and fungible assets. The coin standard is separated out into its own Move module to ensure that:
- Applications and users can create and use simple tokens, with high performance and low gas overhead.
- The Coin standard is part of the Aptos core framework so it can be used for currencies, including the gas currency.

Token V2
The new Token v2 standard allows:
- Rich, flexible assets and collectibles.
- Token v2 can be built up on easily to provide richer custom functionalities. An example of this is the aptos_token module

Token V1
The old existing Token module, on the other hand:
- Encapsulates rich, flexible assets and collectibles. These assets are discrete (non-decimal) and can be fungible, semi-fungible, or nonfungible.
