### Introduction <a href="#introduction" id="introduction"></a>

NEOPIN Connect supports remote connections between App-to-App or Web-to-App using a Relay server to relay payloads. These payloads are symmetrically encrypted and delivered securely using a shared key between the two peers. The connection between App-to-App or Web-to-App is initiated by a DApp running a deep link that contains a QR code or a standard URI and is established when the NEOPIN Wallet approves the connection request.

*Ethereum, Polygon, Klaytn, Tron Networks are currently supported in NEOPIN, and it will be expanded to various mainnets including Finschia and Cosmos compatible networks.*
