What Is EVM-compatible?
EVM compatible means that a blockchain uses the same EVM architecture as the original Ethereum mainnet and is its clone.
EVM compatible blockchains can use the existing smart contracts like ERC-20 unmodified. They can also blockchain explorers, wallets and such with little modifications. This has lead to born to Ethereum clone chains like Polygon, Avalanche C-Chain and BNB Chain.
