ShorelineCrypto has shut down its CEX (centralized crypto exchange) for years.  It is no longer in the business of CEX.

However, since the shut down of CEX, shorelinecrypto has worked on software development on decentralized exchange (DEX) through Cheetahdex Wallet, which supports 400 + token, a Non-Custodial Multi-Coin Wallet & DEX, an open sourced fork of Komodo Wallet.
