FAQ

Yes. You don't share private key through api request. You sign transaction with private key locally only. Library is based on @cryptoscan/swap-sdk

We charge a 0.5% fee on each successful transaction instruction. If you want to decrease fee - please contact us in discord or telegram We can increase fee down to 0.1% if you will contribute us.

You can create pull requests or make a project based on our packages. You have chance to get some supply for a work and get fee reduced for the api.
