How to token swap erc 20 tokens moralis web3

To build a decentralized application (dapp) for swapping ERC20 tokens, you typically use Moralis in conjunction with a decentralized exchange (DEX) aggregator API like the 1inch Aggregation Protocol or 0x API. Moralis itself primarily provides data and backend infrastructure, not the direct on-chain swap execution logic. 

Prerequisites

• Knowledge of smart contracts, Web3.js or Ethers.js, and a DEX aggregator’s API. 

• A Moralis account and API key.

• A user interface (e.g., React, Vue, or vanilla JS) to connect a wallet (e.g., MetaMask).
  

For detailed technical guides and code examples, the Moralis documentation and official YouTube tutorials offer extensive resources on building a DEX.
