# Reading Attestations Off-Chain

This step-by-step guide will run you through programatically reading attestations offchain using Typescript SDKs for EAS and Verax protocols.

### Verax

Find the full Verax SDK documentation [here](https://docs.ver.ax/verax-documentation/developer-guides/using-the-sdk).

Start by installing the Verax SDK package.

```sh
# npm
npm i --save @verax-attestation-registry/verax-sdk
```

Next create a typescript file in a node project and paste the following code.

```typescript
// ES6
import { VeraxSdk } from "@verax-attestation-registry/verax-sdk";

const veraxSdk = new VeraxSdk(VeraxSdk.DEFAULT_LINEA_TESTNET_FRONTEND);

const attestationDataMapper = veraxSdk.attestation; // RW Attestations

const myAttestation = await attestationDataMapper.findOneById("0x000000000000000000000000000000000000000000000000000000000000109b");

// args:
// 	- criteria: object {property1: value1, property2: value2, ...}
// 	- page: integer (optional, default 0)
// 	- offset: integer (optional, default 50, max= 500)
// 	- orderBy: string (optional, default createdAt)
// 	- order(property?): enum string "ASC", "DESC" (optional, default "DESC")
//
const myAttestations = await attestationDataMapper.findBy(
  { portalId: "37773", subject: "John" },
  4,
  30,
  "schemaId",
  "ASC",
);

console.log(myAttestations);
```

### EAS

Find the full EAS SDK documentation [here](https://docs.attest.sh/docs/developer-tools/eas-sdk).

Start by installing the EAS SDK package.

```typescript
npm install @ethereum-attestation-service/eas-sdk
```

Next create a typescript file and paste in the following code

```typescript
import { EAS } from "@ethereum-attestation-service/eas-sdk";
import { EAS, Offchain, SchemaEncoder, SchemaRegistry } from "@ethereum-attestation-service/eas-sdk";
import { ethers } from 'ethers';

export const EASContractAddress = "0xC2679fBD37d54388Ce493F1DB75320D236e1815e"; // Sepolia v0.26

// Initialize the sdk with the address of the EAS Schema contract address
const eas = new EAS(EASContractAddress);

// Gets a default provider (in production use something else like infura/alchemy)
const provider = ethers.providers.getDefaultProvider(
  "sepolia"
);

// Connects an ethers style provider/signingProvider to perform read/write functions.
// MUST be a signer to do write operations!
eas.connect(provider);

// The UID of the attestation we want to fetch
const uid = "0xff08bbf3d3e6e0992fc70ab9b9370416be59e87897c3d42b20549901d2cccc3e";

const attestation = await eas.getAttestation(uid);

console.log(attestation);
```
