The biggest hurdles when scaling web3.js apps are network congestion and slow transaction speeds. As more users use the dApp, blockchain transactions may cost more and take longer. To address this, web3.js apps often use Ethereum scaling solutions such as layer-2 rollups or sidechains, but these add complexity. Finding solutions that make apps faster without compromising security or decentralisation is a key challenge for web3.js developers.
