Web3 & Blockchain Engineering

What we build

Smart contract integration and audit prep, MetaMask/WalletConnect auth, ERC-20 payment rails, ERC-721 access control, custom Discord/Telegram bots, and edge-cached ownership proofs so your checkout stays fast.

Where it shows up

The Israel fashion brand's token-gated customisation, the WooCommerce ERC-20 gateway for the healthcare project, and multi-year work with several DeFi/NFT communities.

Example

// Edge-cached ownership proof (Cloudflare Workers)
export default {
  async fetch(req: Request, env: Env) {
    const url = new URL(req.url);
    const wallet = url.searchParams.get("wallet");
    const key = `own:${wallet}`;
    const cached = await env.KV.get(key);
    if (cached) return new Response(cached, { headers: { "content-type": "application/json" } });
    const owns = await provider.call(nft, "balanceOf", [wallet]);
    const body = JSON.stringify({ owns: owns > 0n });
    await env.KV.put(key, body, { expirationTtl: 60 });
    return new Response(body, { headers: { "content-type": "application/json" } });
  }
};
