Something like BTCPayServer that work with Tron tokens
I wish accept TRC20 tokens at my site, and take it directly, without serveces that takes fee.
Some library that i can setup on my server.
Here you can try this one dude https://coinspaid.com/ and https://b2binpay.net/ but I just don't exactly so sure if these
two are accepting processor for TRC20, then the other things need to be research and check. Perhaps, you have a huge holdings
of TRX that's why maybe you are asking this thing.
As stated above by OP, He wants to save fee for multiple small transaction for his business which I understand as a fellow businessman. Probably he will just accept TRC20 coin with a consistent huge trading volume and convert it by himself. TRC20 tokens is currently the most efficient token to use for micro transactions due to low transaction fee and great TPS.
Its the transaction fee that is a pain if he uses the USDT (ERC20) even I myself rarely made ETH transactions because of the fees. But with TRC20, its really convenient and not waste tokens for a tiny transaction. I however think only few of us are taking advantage of TRX low fees. If you are using it for business, you just have to accept all tokens.
