1. Navigate to the src\validations.

└── src
    └── validations
        └── basic

2. Create a copy of the basic strategy folder and rename it to the name of your voting validation.

3. Customize the logic of your voting validation.

If you are not sure about the Validation class, have a look at its definition:

https://github.com/snapshot-labs/snapshot-strategies/blob/master/src/validations/validation.ts

export default class Validation {
  public id = '';
  public github = '';
  public version = '';
  public title = '';
  public description = '';

  public author: string;
  public space: string;
  public network: string;
  public snapshot: number | 'latest';
  public params: any;

  constructor(
    author: string,
    space: string,
    network: string,
    snapshot: number | 'latest',
    params: any
  ) {
    this.author = author;
    this.space = space;
    this.network = network;
    this.snapshot = snapshot;
    this.params = params;
  }

  async validate(): Promise<boolean> {
    return true;
  }
}

The validation name has to be included in the index.ts in the validationClasses variable.

4. Test your validation

To make sure your validation passes all tests, run:

npm run test --validation=<VALIDATION NAME> // replace <VALIDATION NAME>
