@memnr/sdk

TypeScript SDK for memnr. Programmatically create mems from videos, read mem data, and interact with on-chain royalty share programs.

Install

npm install @memnr/sdk @solana/web3.js

Quick Start

import { MemnrSDK } from '@memnr/sdk';
import { Connection, Keypair, VersionedTransaction } from '@solana/web3.js';

const sdk = new MemnrSDK('memnr_sk_...', new Connection('https://api.mainnet-beta.solana.com'));
const wallet = Keypair.fromSecretKey(/* ... */);

// List tokens
const { items } = await sdk.tokens.list({ sortBy: 'newest', pageSize: 10 });

// Preview a TikTok video
const preview = await sdk.tokenLaunch.previewVideo('https://tiktok.com/@user/video/123');

// Build launch transaction (server builds + partially signs)
const { launchId, transaction, poolAddress, dbcConfigKey, metadataUri } =
  await sdk.tokenLaunch.buildLaunchTransaction({
    videoUrl: 'https://tiktok.com/@user/video/123',
    payerAddress: wallet.publicKey.toBase58(),
    customTicker: 'MYTK',
  });

// Sign and send
const tx = VersionedTransaction.deserialize(Buffer.from(transaction, 'base64'));
tx.sign([wallet]);
const sig = await sdk.solana.sendAndConfirm(tx);

// Confirm with API
await sdk.tokenLaunch.confirmLaunch({
  launchId,
  signature: sig,
  poolAddress,
  dbcConfigKey,
  metadataUri,
});
