# 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.

### Aptos Token​

The 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.
• The token standard is in its own AptosToken package at the Address 0x3 to allow for rapid iteration based on feedback from the community.

## Wallet standards​

### Aptos Wallet standards​

The wallet standards ensure that all wallets use the same functionality for key features. This includes:

• The same mnemonic so that wallets can be moved between providers.
• Wallet adapter so that all applications can interact seamlessly with a common interface.
