Introduction

ParaSta is a digital asset platform with two API surfaces:

  • Payments API — Accept crypto payments (USDT, USDC, ETH, SOL) on Polygon, Ethereum, and Solana with Hosted Checkout or QR. Settle in coin or KRW.
  • Platform API — KYC, asset connection (banks, securities, crypto exchanges, wallets), transfers, charges, exchange. Originally built for the ParaSta consumer app and exposed here for partners building on the platform.

If you are integrating crypto payments, start with Quickstart.

If you are extending the consumer app’s surface area, see Platform APIs.
