    Validating Sets

    This package does not include code for token list validation. You can easily do this by including a library such as ajv to perform the validation against the JSON schema. The schema is exported from the package for ease of use.

    import Ajv from 'ajv';
    import { smartcontract } from '@metameta-protocol/metasets-schema'
    const ajv = new Ajv({ allErrors: true });
    const validate = ajv.compile(smartcontract);
    const response = await fetch('')
    const listData = await response.json()
    const valid = validate(listData)
    if (!valid) {
      // oh no!

    Creating Sets


    The best way to manually author token lists is to use an editor that supports JSON schema validation. Most popular code editors do, such as IntelliJ or VSCode. Other editors can be found here.

    In order for your set to be able to be used, it must pass all JSON schema validation specific to that type.

    Semantic versioning

    Sets include a version field, which follows semantic versioning.

    Each set will have specific rules defining versioning but generally a good rule of thumb is...

    • Increment major version when an Entity is removed
    • Increment minor version when an Entity is added
    • Increment patch version when an Entity already on the list have minor details changed that don't effect the set outcome.
