> vsnation will expand buyfiro.app to allow payment to any supported coin including stablecoins and also integrate Spark address support. This means that users can pay using Firo Spark and then the merchant will receive the corresponding stablecoin/other coin payment. In principle, I agree with most if not all of the proposal. I am new, but it’d seem to me like buyfiro.app is a good-looking website, offering an on-ramp for FIRO, which is hopefully getting amplified to _pay with_ and… correct me if I am wrong, but somewhere you imply… **selling** as well, no? While we definitely can see the proof-of-work with current website and shared volumes, metrics, and while I would not be asking for a proof-of-concept per se… Could we get some mockup images and even (optional) graphs explaining the infrastructure, the product as you have thought about it? How exactly you plan on implementing a pay-with-FIRO and selling-FIRO-to-site, for buyfiro.app? I’d appreciate a more visual idea, if possible. In my opinion, it’d help visualize better what you plan on building, e.g. what programming language it’ll be coded with, will it be all FOSS-friendly (license…) the front-end, at least, most exchanges, on/off ramps aren’t FLOSS in the first place, will it be proprietary code, will you take this almost ~$5k **donation** to craft LP and bolster liquidity as a token for long-term maintenance of the project? --- _[View the full topic](https://forum.firo.org/t/fcs-proposal-pay-using-firo-for-anything-using-spark/4366)._
