Test the file validity

Before submitting your metadata to the registry or deploying your implementation, use this testing tool to ensure your metadata file complies with the ERC-7730 standard.

JSON schema validator

Use the schema validator to check your metadata files for compliance with the ERC-7730 standard:

import Ajv from 'ajv';
import schema from '@ledgerhq/clear-signing-schemas';
 
const ajv = new Ajv();
const validate = ajv.compile(schema);
 
function validateMetadata(metadata) {
  const valid = validate(metadata);
  if (!valid) {
    console.error('Validation errors:', validate.errors);
    return false;
  }
  return true;
}
