onchainid.removeClaimFromIdentity(RemoveClaimFromIdentity)

Remove a claim from an ONCHAINID identity by claimId. This sends a transaction to the identity contract and requires the identity owner’s signer.

​
RemoveClaimFromIdentity Type Parameters

ParameterTypeRequiredDescription
subjectIdentitystringRequiredThe ONCHAINID identity contract address to modify.
identityControllerSignerRequiredThe signer authorized to remove claims from the identity (controller).
claimIdstringRequiredThe claim identifier, computed as keccak256(abi.encode(issuer, topic)).
Note: The claimId uniquely identifies a claim for an identity. It is derived from the issuer contract address and the claim topic: in Solidity keccak256(abi.encode(_issuer, _topic)). In ethers this can be reproduced with keccak256(new AbiCoder().encode(["address","uint256"], [issuer, topic])).

​
Returns

FieldTypeDescription
statusremovedStatus of the removal.
claimIdstringClaim ID removed from the identity.
receiptTransactionReceiptThe transaction receipt confirming claim removal.

Usage

​
TypeScript

import 'dotenv/config';
import { RWA, Chain, ClaimTopics, type SDKInit, type GetIdentity, type RemoveClaimFromIdentity } from '@peaq-network/rwa';
import { JsonRpcProvider, AbiCoder, keccak256, Wallet } from "ethers";

async function main() {
    // 0. Create rwa_sdk instance and get 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. Resolve the identity for an EOA (or use a known identity address)
    const alice = process.env.ALICE_PUBLIC_ADDRESS!;
    const identityRes = await rwa_sdk.onchainid.getIdentity({ subject: alice } as GetIdentity);
    if (identityRes.status !== 'found') throw new Error('Identity not found');
    const identity = identityRes.identity;

    // 2. Identity owner signer
    const identityOwner = new Wallet(process.env.ALICE_PRIVATE_KEY!, provider);

    // 3. Compute claimId = keccak256(abi.encode(issuer, topic))
    const issuerContract = process.env.CLAIM_ISSUER_CONTRACT_ADDRESS!;
    const topic = ClaimTopics.CT_KYC_APPROVED;
    const abiCoder = new AbiCoder();
    const claimId = keccak256(abiCoder.encode(["address", "uint256"], [issuerContract, topic]));

    // 4. Remove claim from identity
    const result = await rwa_sdk.onchainid.removeClaimFromIdentity({
      subjectIdentity: identity,
      identityController: identityOwner,
      claimId
    } as RemoveClaimFromIdentity);
    console.log("Result", result);
}

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