I found some time to work on Transponder. I reached the limitations of developing something alone:

- Matrix client SDK's are absolute far from mature, the API changes still a lot.

- Telegram is already fulfilled by Depecher, it does the job pretty good.

- Multiprotocol is a hell

I am not going to build further on Transponder due my limit resources, instead I will focus on my other apps. They need some more love
