Hello. I am a somewhat newbie to Bitcoin but I own a few ecommerce sites selling various products. My suppliers in Asia are willing to accept BTC/LTC as a method of payment

I am using open source shopping carts but then using a 3 party processor in my Merchant Account (for accepting Visa, etc). I then have to get another processor (Coinbase, Bitpay, CoinPayments, etc) to accept crypto payments for good. Basically looking for something that will allow customer to checkout thru a IE Magento shopping cart and allow them to pay me directly. Basically Bitpay but without the Bitpay

My question to the community is there a Open source plugin that will work with Magento, OSC, etc that will allow me to accept Crypto payments WITHOUT going thru one of the companies above?

Crypto currency are suppose to be the "Currency/Payment Tool of the People" but there are only 3rd party companies solving simple community needs that makes buying on a ecommerce site simple and easy! Has anyone built or building a solution like this? If so, Please Let me know And please send me the sites so I can see how it looks from the front end
