fuellabs/sway-standards

This repository defines official standards for Sway, which is the smart contract programming language used on the Fuel blockchain. A smart contract is a program that runs automatically on a blockchain and controls things like digital assets or agreements. Standards like these serve a similar role to standards in any other industry: they give developers a shared set of rules so that different contracts and tools can work together predictably. The standards here cover things like how to define a digital asset (called a Native Asset on Fuel), how to handle minting and burning tokens, how to build a vault that holds assets for others, and how to attach metadata to a token. Each standard is identified by a code like SRC-20 or SRC-3, following a naming pattern similar to standards on other blockchain platforms. To use one of these standards in a Sway project, you add it as a dependency in your project's configuration file using a command-line tool called forc, then import the relevant interface into your contract code. The README includes short examples showing exactly how to do this. Some standards are still drafts, meaning they are proposed but not finalized. The project encourages developers to try drafts and give feedback. If a developer needs a standard that does not exist yet, they can open an issue to propose one. Sway itself is still being actively developed, so the standards are expected to be refined over time.
