Gitcoin Passport SDK: Verifier

Verify the contents of a Gitcoin Passport

Installation

Add to your project...

yarn add @gitcoinco/passport-sdk-verifier

--

Or download this .git repository and install deps manually...

yarn install

Build...

yarn run webpack

Basic Usage

Firstly, we need to import the library/bundle and construct a PassportVerifier instance

// import as a module
import PassportVerifier from "@gitcoinco/passport-sdk-verifier";


// or import the bundle
<script src="./dist/verifier.bundle.js" type="script/javascript"/>

...

// create a new instance pointing at the community clay node on mainnet along with the criteria we wish to score against
const verifier = new PassportVerifier();

// Verify all Stamps held within a Passport
const passport = await verifier.verifyPassport("0x0...");

Browser Usage

If you are using this package in a browser, you may need to asynchronously load @gitcoinco/passport-sdk-verifier'` before using.

// NextJS Example
const [verifier, setVerifier] = useState();

useEffect(() => {
  const initVerifier = async () => {
    // Dynamically load @gitcoinco/passport-sdk-verifier
    const PassportVerifier = (await import("@gitcoinco/passport-sdk-verifier")).PassportVerifier;
    setVerifier(new PassportVerifier("https://ceramic.staging.dpopp.gitcoin.co"));
  };

  initVerifier().then(() => {
    console.log("Verifier inited :)");
  });
}, []);

PassportVerifier

The PassportVerifier instance exposes read-only methods to verify the content of a Gitcoin Passport:

• verifyPassport - pass in an ethereum address and get back a Passport where each stamps contains a verified: boolean field

PassportVerifier.verifyPassport(address: string, passport?: Passport, additionalStampCheck?: (stamp: Stamp) => boolean): Promise<Passport>

• verifyStamp - pass in a Stamp and get back a Stamp with the verified: boolean field completed

PassportVerifier.verifyStamp(address: string, stamp: Stamp, additionalStampCheck?: (stamp: Stamp) => boolean): Promise<Stamp>

• verifyCredential - pass in a VerifiableCredentail and get back a boolean

PassportVerifier.verifyCredential(credential: VerifiableCredential): Promise<boolean>
