Sway Standards

Just like many other smart contract languages, usage standards have been developed to enable cross compatibility between smart contracts.

For more information on using a Sway Standard, please refer to the Sway-Standards Repository.

Standards

SRC-20; Native Asset Standard defines the implementation of a standard API for Native Assets using the Sway Language.
SRC-3; Mint and Burn is used to enable mint and burn functionality for Native Assets.
SRC-7; Arbitrary Asset Metadata Standard is used to store metadata for Native Assets, usually as NFTs.
SRC-9; Metadata Keys Standard is used to store standardized metadata keys for Native Assets in combination with the SRC-7 standard.
SRC-6; Vault Standard defines the implementation of a standard API for asset vaults developed in Sway.

SRC-13; Soulbound Address Standard defines a specific Address as a Soulbound Address for Soulbound Assets to become non-transferable.

SRC-5; Ownership Standard is used to restrict function calls to admin users in contracts.

SRC-12; Contract Factory defines the implementation of a standard API for contract factories.

SRC-8; Bridged Asset defines the metadata required for an asset bridged to the Fuel Network.
SRC-10; Native Bridge Standard defines the standard API for the Native Bridge between the Fuel Chain and the canonical base chain.

Libraries have also been developed to support Sway Standards. These can be in Sway-Libs.
