I am new to binance’s spot api. We are developing a swapping system just like changelly.com where one user wants to swap BTC against ETH. He would deposit the BTC to generated address and provide his ETH’s wallet address and after transaction is done, changelly would deposit equivalent ETH to his ETH wallet.
How can we achieve using binance apo api ?
We’re not familiar changelly.com, what’s the specific detail you would like to obtain to see if we can help? Giving the general idea is not very suitable 
See…
Out project is at https://coinbns.com
Here we are providing crypto swapping service to users
Currently we are consuming 7 exchanges api to fetch the swapped amount etc…
We need to implement binance api for swapping too
