# Claim UBI (Ethers v5/ React)

{% hint style="warning" %}
Please ensure you have [followed the steps to set up the context provider](/for-developers/developer-guides/ethers-v5-usedapp-context-setup.md) for this SDK.
{% endhint %}

Make sure user wallet is whitelisted, see [Identity](/for-developers/apis-and-sdks/sybil-resistance.md).

First, create the SDK.\
The first argument should be an ethers Web3Provider, since the user will need to sign transactions.\
Second argument is which environment and chain contract set to use.<br>

{% hint style="info" %}
Every user can claim every day from every chain that has a UBI pool
{% endhint %}

```typescript
import { ClaimSDK } from "@gooddollar/web3sdk-v2"

const sdk = new ClaimSDK(web3provider, "production" | "production-celo")
```

Check if the user is currently eligible to claim today:

```typescript
const claimAmount = await sdk.checkEntitlement() // if claimAmount > 0 user can claim
```

Then, perform claim:

```typescript
await sdk.claim()
```

You can also get the next `Date` when the user will be eligible to claim again

```typescript
const nextClaimTime = await sdk.getNextClaimTime()
```

### React hooks

You can also use our react hooks to manage claim.

See the Claim/Identity react hooks code [here](https://github.com/GoodDollar/GoodWeb3-Mono/blob/master/packages/sdk-v2/src/sdk/claim/react.ts).\
Storybook examples [here](https://github.com/GoodDollar/GoodWeb3-Mono/tree/master/packages/sdk-v2/src/stories/claim).\
You will need to first setup our context provider as explained [here](/for-developers/developer-guides/ethers-v5-usedapp-context-setup.md).
