It is now possible to connect a TurtleCoin full node that you control, via its wallet-api, to the Bitcoin and Altcoin Wallets plugin for WordPress.

TurtleCoin is a modern, privacy-focused coin, with a fairly active developer community. The coin is easily forkable, comes with instructions for how to set it up as a service, and comes with a well-designed wallet API. The documentation around all aspects of the coin is excellent.
