Does Coinbase have a bridge?

I'm curious to know, does Coinbase, a popular cryptocurrency exchange platform, have a bridge in place that allows for seamless transfer of assets between different blockchains? I understand that cross-chain interoperability is becoming increasingly important in the crypto space, and I'm wondering if Coinbase has taken any steps to enable this functionality for their users. If they do, what specific blockchains are supported, and how does the bridge work? It would be great to get some clarity on this topic.
