Hello, I have experience in product design and marketing. But, I'm not technical. I have an idea for two new products for the marketing industry. They would use bitcoin on-chain and lightning (and cashu ecash later on) for payment flows.

An existing tool built on React that is no longer maintained has inspired me. It has come from the effort of an indy-hacker that before shared the open source code on github. The code is not there any more, but I did find some forks with GPL-3.0 licence. Another fork has an AGPL-3.0 licence. I don't know the difference. From my understanding, this licence allows to reuse the code.

I'm looking for a technical partner to analyse the existing code. Remove the fiat payment gateways. Implement only bitcoin/lightning options. In the worst case, it may be easier to rebuild from scratch using this tool as a reference.

I seek advice on how to proceed. What are the best technical practices for launching such a product?

Thanks in advance for your comments and opinions.
