Instructions

Step 1: Response Caching with TTL

// src/performance/cache.ts
import { Alchemy, Network } from 'alchemy-sdk';

class BlockchainCache {
  private store = new Map<string, { data: any; expiry: number }>();

  // Different TTLs for different data freshness needs
  private TTL: Record<string, number> = {
    blockNumber: 12000,     // 12s (~1 block)
    balance: 30000,         // 30s
    tokenBalances: 60000,   // 60s
    nftOwnership: 300000,   
    : , 
    : ,   
  };

   cached<T>(: , : , :  <T>): <T> {
     cacheKey = ;
     entry = ..(cacheKey);
     (entry && entry. > .())  entry.;

     data =  ();
    ..(cacheKey, { data, : .() + (.[category] || ) });
     data;
  }

  (: ):  {
     ( key  ..()) {
       (key.()) ..(key);
    }
  }
}

 cache =  ();
 { cache };
