onchainid.addClaimToIdentity(AddClaimToIdentity)

Add a signed claim to an ONCHAINID identity (calls the identity contract’s addClaim).

​
AddClaimToIdentity Type Parameters

ParameterTypeRequiredDescription
subjectIdentitystringRequiredONCHAINID identity contract address that will receive the claim.
identityControllerSignerRequiredSigner/wallet that controls the identity, connected to a provider.
claimIClaimRequiredEncoded claim payload: { identity, issuer, topic, scheme, data, uri }.
claimSignaturestringRequired0x-prefixed hex signature over the claim by the claim issuer.

​
Returns

FieldTypeDescription
statusadded or updated'added' when the claim is new, 'updated' when it replaces an existing claim.
claimIdstringClaim ID emitted by the identity contract.
receiptTransactionReceiptTransaction receipt of the addClaim call.

Usage

​
TypeScript

import 'dotenv/config';
import { RWA, Chain, 
    type SDKInit, 
    type GetIdentity, 
    type IssueKycClaim, 
    type AddClaimToIdentity } from '@peaq-network/rwa';
import { JsonRpcProvider, Wallet } from 'ethers';

async function main() {
  // 0. Create RWA instance and provider
  const provider = new JsonRpcProvider(process.env.HTTPS_BASE_URL);
  const init: SDKInit = { chainId: Chain.AGUNG, provider: provider };
  const rwa_sdk = new RWA(init);

  // 1. Claim Issuer admin wallet
  const claimIssuer = new Wallet(process.env.CLAIM_ISSUER_PRIVATE_KEY!, provider);

  // 2. Get User to KYC
  const getIdentity: GetIdentity = { subject: process.env.ALICE_PUBLIC_ADDRESS! };
  const alice = await rwa_sdk.onchainid.getIdentity(getIdentity);

  // 3. Create claim + signature
  const issueKycClaim: IssueKycClaim = {
    claimIssuerSigner: claimIssuer,
    claimIssuerContract: process.env.CLAIM_ISSUER_CONTRACT_ADDRESS!,
    subjectIdentity: alice.identity,
    name: 'Alice',
    lastName: 'Doe',
    dateOfBirth: '1990-01-01',
    placeOfBirth: 'New York',
    uri: 'https://example.com/kyc'
  }
  const { claim, signature } = await rwa_sdk.onchainid.issueKycClaim(issueKycClaim);

  // 4. Identity owner signs and submits addClaim
  const aliceSigner = new Wallet(process.env.ALICE_PRIVATE_KEY!, provider);
  const addClaimToIdentity: AddClaimToIdentity = {
    subjectIdentity: alice.identity,
    identityController: aliceSigner,
    claim: claim,
    claimSignature: signature,
  }
  const { receipt, status, claimId } = await rwa_sdk.onchainid.addClaimToIdentity(addClaimToIdentity);

  console.log('Add claim result:', { status, claimId, receipt });
}

main().catch((err) => {
  console.error(err);
  process.exit(1);
});

Example outputs

{
  status: 'added',
  claimId: '0x29753f23d65eadcfc30f6988fa876cef5069d80f61802576d029c1272a2c9c4e',
  receipt: TransactionReceipt {
    ...
    hash: '0xabccaf471ad0afa2f059747baeb7f79be3d41ecdaae1beed0bd3d903348b302a',
    status: 1
  }
}
Notes:
  • Ensure identityController controls the ONCHAINID at subjectIdentity.
  • claimSignature must match the exact claim payload and issuer.
