@telika/sdk

TypeScript SDK for the Telika blockchain-anchored verification system on Polygon.

Installation

npm install @telika/sdk

Quick Start

import { ProofGenerator, BlockchainClient } from '@telika/sdk';

// Generate a proof for an identity verification event
const proof = ProofGenerator.createIdentityProof({
  telikaId: 'TLK-001',
  verificationMethod: 'document-check',
  verifiedAt: Date.now(),
  verifierAddress: '0x...',
});

// Anchor it on Polygon
const client = new BlockchainClient({
  contractAddress: '0x...',
  rpcUrl: 'https://polygon-mainnet.g.alchemy.com/v2/YOUR_KEY',
  privateKey: '0x...',
});

const tx = await client.anchorProof(
  proof.hash,
  0, // EventType.IdentityVerification
  'TLK-001',
  JSON.stringify(proof.metadata)
);

Event Types

| Type | Value | Description | |------|-------|-------------| | IdentityVerification | 0 | Founder identity verified | | FundingDisbursement | 1 | Funding sent to founder | | MilestoneConfirmation | 2 | Milestone achieved | | ScoreUpdate | 3 | Telika score recalculated |

API

ProofGenerator

• generateProofHash(eventData) — Generate a keccak256 proof hash
• createIdentityProof(data) — Create an identity verification proof
• createFundingProof(data) — Create a funding disbursement proof
• createMilestoneProof(data) — Create a milestone confirmation proof
• createScoreProof(data) — Create a score update proof
• generateMetadata(eventType, options) — Generate proof metadata

BlockchainClient

• anchorProof(hash, eventType, telikaId, metadata) — Anchor a proof on-chain
• verifyProof(proofHash) — Verify a proof exists on-chain
• getProofsByTelikaId(telikaId) — Get all proofs for a Telika ID
• listenForProofs(callback) — Listen for new proof events
