Create documentation Guide: EVM Chain Support

[mconnelly8]

The guide explains how Web3.js seamlessly integrates with various EVM-compatible chains. It provides instructions on configuring the Web3 instance with a provider URL, which can be easily found on platforms like Chainlist. The guide also includes examples for popular EVM-compatible L1s and L2s.

As of today, the most popular (based on TVL) L2s are:

• Base
• Arbitrum
• Optimism

Popular EVM-compatible L1s include:

• Binance Smart Chain (BSC)
• Avalanche
• Polygon

Sources:

• DefiLlama: EVM Chains
• L2Beat: Scaling TVL

Here’s an example code for Mantle, but the guide should primarily focus on configuring the provider. It should also highlight new provider options, if relevant, such as QuickNode, PublicNode, and others.

Here are the RPC URLs and example ERC-20 token addresses that I’ve verified to work with basic Web3.js functionality, as described in my Mantle example code above.
