Alchemy Core Workflow A — Wallet Portfolio Tracker

Overview

Primary workflow: build a wallet portfolio tracker using Alchemy's Enhanced APIs. Combines getTokenBalances, getNftsForOwner, getAssetTransfers, and token metadata to create a complete wallet view across ERC-20, ERC-721, and ERC-1155 assets.

Prerequisites

• Completed alchemy-install-auth setup
• alchemy-sdk installed
• Understanding of Ethereum address format and token standards

Instructions

Step 1: Portfolio Data Fetcher

// src/portfolio/fetcher.ts
import { Alchemy, Network, AssetTransfersCategory } from 'alchemy-sdk';

const alchemy = new Alchemy({
  apiKey: process.env.ALCHEMY_API_KEY,
  network: Network.ETH_MAINNET,
});

interface TokenHolding {
  contractAddress: string;
  symbol: string;
  name: string;
  balance: number;
  decimals: number;
}

interface NftHolding {
  contractAddress: string;
  collectionName: string;
  tokenId: string;
  name: string;
  imageUrl:  | ;
}

  {
  : ;
  : ;
  : [];
  : [];
  : [];
  : ;
}

  (): <> {
  
   [ethBalance, tokenBalances, nftResponse, transfers] =  .([
    alchemy..(address),
    alchemy..(address),
    alchemy..(address, { :  }),
    alchemy..({
      : address,
      : [
        .,

  ]);

  
   : [] = [];
   ( tb  tokenBalances.) {
     (tb. && tb. !== ) {
       metadata =  alchemy..(tb.);
       balance = (tb., ) / .(, metadata. || );
       (balance > ) {  
        tokens.({

          balance,

      }
    }
  }

  
   : [] = nftResponse..( ({
    : nft..,
    : nft.. || ,
    : nft.,
    : nft. || ,
    : nft.?. || ,
  }));

   {
    address,
    : ((ethBalance.()) / ).(),
