Delegate your tokens to validators on Cosmos chains to earn staking rewards using CosmJS in React Native.

## Prerequisites

<Card title="Setup CosmJS Libraries" description="Configure CosmJS with Para SDK first" href="/v2/react-native/guides/web3-operations/cosmos/setup-libraries" icon="gear" horizontal />

## Stake Tokens

```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 { MsgDelegate } from 'cosmjs-types/cosmos/staking/v1beta1/tx';

const RPC_URL = 'https://rpc.cosmos.directory/cosmoshub';

function StakeTokens() {
  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 delegateToValidator = async () => {
    if (!protoSigner || !address) return;

    const validator = 'cosmosvaloper1...';

    const msgDelegate = {
      typeUrl: '/cosmos.staking.v1beta1.MsgDelegate',
      value: MsgDelegate.fromPartial({
        delegatorAddress: address,
        validatorAddress: validator,
        amount: {
          denom: 'uatom',
          amount: '1000000',
        },
      }),
    };

    const fee = {
      amount: coins(5000, 'uatom'),
      gas: '250000',
    };

    try {
      const result = await signAndBroadcastAsync({
        messages: [msgDelegate],
        fee,
        memo: 'Staking with Para',
      });

      console.log('Delegation successful:', result.transactionHash);
    } catch (error) {
      console.error('Delegation failed:', error);
    }
  };

  if (isLoading) return <Text>Loading...</Text>;

  return (
    <View>
      <Text>Delegator: {address}</Text>
      <Button
        title={isPending ? 'Staking...' : 'Stake 1 ATOM'}
        onPress={delegateToValidator}
        disabled={isPending}
      />
    </View>
  );
}
```
