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
| Parameter | Type | Required | Description |
|---|---|---|---|
| subjectIdentity | string | Required | The ONCHAINID identity contract address to modify. |
| identityController | Signer | Required | The signer authorized to remove claims from the identity (controller). |
| claimId | string | Required | The claim identifier, computed as keccak256(abi.encode(issuer, topic)). |
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
| Field | Type | Description |
|---|---|---|
| status | removed | Status of the removal. |
| claimId | string | Claim ID removed from the identity. |
| receipt | TransactionReceipt | The 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) => {
