What's the price and can we test the interface first before dealing ?
I will send you PM.
The formular is the major secret and it can not be revealed unless the buyer is ready by sending funds to the escrow account.
The test interface shall be done using your token.
Kindly contact any escrow on that list ( I will not be liable for any loss, please do your research and before sending funds to the escrow account, i shall pay for the fees)
