Welcome to the Kotani Pay source code repository!
Kotani Pay is a stablecoin to fiat on-ramp and off-ramp service. The service is offered as an end to end API (Application Programming Interface) to enable other businesses to integrate and also as a USSD (Unstructured Supplementary Service Data) application for end-users to convert stablecoins to local fiat.
The Kotani Pay API enables Blockchain protocols, decentralized applications and FinTech services to connect to traditional payment systems to enable cash out to bank and mobile money accounts. Kotani Pay offers a simple integration experience.
Majority of Blockchain protocols require internet access and installation of additional mobile applications or wallets. This limits their adoption locking out the users who are set to benefit the most. Kotani Pay through the API makes access to these protocols and their tokens possible without the need of an Internet connection.
At the moment, you can only use our "app" via USSD. In the near future, we will also release mobile apps and a web version.
Some of the groundbreaking features on the USSD app include; Create Account, Send Money, Deposit Funds, Withdraw Cash, My account and Short Message Service (SMS) Response Option
Create Account: Users can easily create their accounts by accessing a USSD code eg *483*354# on their GSM or Smartphone device. The user will be issued with an account mapped to their phone number complete with their seed key phrase, Blockchain private key, Blockchain public key and PIN. Send Money: Users can send currencies that live on the Celo Blockchain to other users.This transaction is performed from a USSD command interface or a social messaging interface (WhatsApp, Telegram).
Deposit Funds: Users can receive Blockchain based currencies to their accounts from cash deposits on popular mobile financial Services e.g. M-Pesa.
Withdraw Cash: Users can withdraw cash through local mobile financial services from the Celo Blockchain using their USSD command interfaces or social messaging interfaces.
My account: Access all information related to the user account: Check balance, check deposit and withdrawal history
SMS response Option: Users receive delivery reports and transaction status on SMS.
