@glurk-protocol/sdk

The identity protocol for the internet. Apps trade data. Users own everything. Built on Solana.

What is this?

Glurk lets any Solana app issue permanent, non-transferable, verifiable credentials to users. Think of it as Aadhaar for skills — one system that stores "this person knows X" and anyone can check it.

• Non-transferable — credentials can't be sold or faked (Token-2022 NonTransferable extension)
• Permanent — lives on Solana, not on anyone's server
• Open — any registered issuer can write, any app can read
• Composable — DeFi protocols, job platforms, DAOs can all verify credentials without trusting any API

Quick Start

Verify a credential

import { verifyCredential, KNOWN_ISSUERS } from '@glurk-protocol/sdk';

const cred = await verifyCredential(
  'https://api.devnet.solana.com',
  KNOWN_ISSUERS.STAQ,
  userWallet,
  'credit-score',
);

if (cred) {
  console.log(`${cred.tier} tier, score ${cred.score}/100`);
}

Get a user's full profile

import { getProfile } from '@glurk-protocol/sdk';

const { credentials, glurkScore, consents } = await getProfile(
  'https://api.devnet.solana.com',
  userWallet,
);
// glurkScore: 0-1000 reputation derived from all credentials
// credentials: every verified skill across all issuers

GlurkClient

import { GlurkClient, KNOWN_ISSUERS } from '@glurk-protocol/sdk';

const client = new GlurkClient('https://api.devnet.solana.com');

const cred = await client.verifyCredential(KNOWN_ISSUERS.STAQ, userWallet, 'stocks');
const score = await client.getScore(userWallet);
const issuer = await client.checkIssuer(someIssuerPubkey);

Use Cases

DeFi / Lending:

User has Gold-tier financial literacy credentials → offer 20% lower collateral requirement

Job Platforms:

User has verified coding + finance credentials → surface for fintech roles automatically

DAOs:

Only members with specific credentials can vote on treasury decisions

Education Platforms:

Issue your own credentials through the protocol. Your students carry them everywhere.

How Credentials Work

1. Issuers register with the protocol (approved by protocol admin)
2. Issuers write credentials to user wallets via the Anchor program
3. Credentials are PDAs seeded by [issuer, user, slug] — deterministic and readable by anyone
4. Any Solana program can derive the PDA and read the credential without any API call

PDA = findProgramAddress(["credential", issuer, user, "credit-score"], PROGRAM_ID)

If the account exists → credential is verified. Read the data for tier, score, and timestamp.

Protocol Adapters

Helpers for building third-party integrations on top of Glurk credentials.

calculateDynamicCollateral(baseRatio, glurkScore)

Maps a user's Glurk Score (0–1000) to a discounted collateral ratio for lending protocols. Discounts kick in above a 300-score threshold, scale linearly to a 35% max reduction at 1000, and are floored at 1.05× to prevent flash-loan liquidation exploits.

import { calculateDynamicCollateral } from '@glurk-protocol/sdk';

// Standard pool requires 150% collateral
const baseRatio = 1.5;

calculateDynamicCollateral(baseRatio, 0);    // 1.5  (no credentials → no discount)
calculateDynamicCollateral(baseRatio, 300);  // 1.5  (below threshold)
calculateDynamicCollateral(baseRatio, 600);  // 1.275
calculateDynamicCollateral(baseRatio, 1000); // 1.05 (max discount, hard floor)

Drop-in for Kamino-style undercollateralized vaults: read the user's Glurk Score once via getProfile, then pass it into your pool's collateralization math.

Become an Issuer

Want to issue credentials through the protocol? You need:

1. A Solana wallet (your issuer identity)
2. Approval from the protocol admin
3. That's it — use the SDK to start issuing
