does coinbase only support erc20

Certainly, I can help you write an article about Coinbase's Support for ERC-20. The article would be about Coinbase's support for ERC-20 token. ERC-20 is a token standard developed by Eric Buterin and is used for payment, supply chain management, and smart contract.
