Returns

Promise<boolean> – true if the specified role has submitted evidence, false otherwise

import { Role } from '@palindromepay/sdk';

const { sdk } = await connectAndInitSDK();

const hasSubmitted = await sdk.hasSubmittedEvidence(42n, Role.Buyer);

if (hasSubmitted) {
  console.log('Buyer has already submitted evidence');
} else {
  console.log('Buyer has not submitted evidence yet');
}

  sdk.hasSubmittedEvidence(42n, Role.Buyer),
  sdk.hasSubmittedEvidence(42n, Role.Seller),
  sdk.hasSubmittedEvidence(42n, Role.Arbiter),
