# Claim Staking Rewards
> Claim accumulated staking rewards from delegated validators
Withdraw your accumulated staking rewards from validators on Cosmos chains using CosmJS in React Native.
## Prerequisites
## Claim Rewards
```typescript theme={null}
import { useMemo } from 'react';
import { View, Text, Button } from 'react-native';
import { useParaCosmjsProtoSigner, useParaCosmjsSignAndBroadcast } from '@getpara/react-native-wallet/cosmos';
import { SigningStargateClient, coins } from '@cosmjs/stargate';
import { MsgWithdrawDelegatorReward } from 'cosmjs-types/cosmos/distribution/v1beta1/tx';
const RPC_URL = 'https://rpc.cosmos.directory/cosmoshub';
function ClaimRewards() {
const { protoSigner, isLoading } = useParaCosmjsProtoSigner();
const address = protoSigner?.address;
const client = useMemo(
() => protoSigner ? SigningStargateClient.connectWithSigner(RPC_URL, protoSigner) : undefined,
[protoSigner]
);
const { signAndBroadcastAsync, isPending } = useParaCosmjsSignAndBroadcast(protoSigner, client);
const claimStakingRewards = async () => {
if (!protoSigner || !address) return;
const validator = 'cosmosvaloper1...';
const msgWithdrawReward = {
typeUrl: '/cosmos.distribution.v1beta1.MsgWithdrawDelegatorReward',
value: MsgWithdrawDelegatorReward.fromPartial({
delegatorAddress: address,
validatorAddress: validator,
}),
};
const fee = {
amount: coins(5000, 'uatom'),
gas: '200000',
};
try {
const result = await signAndBroadcastAsync({
messages: [msgWithdrawReward],
fee,
memo: 'Claiming rewards via Para',
});
console.log('Rewards claimed:', result.transactionHash);
console.log('Gas used:', result.gasUsed);
} catch (error) {
console.error('Failed to claim rewards:', error);
}
};
if (isLoading) return Loading...;
return (
Delegator: {address}
);
}
```
