NEOPIN supports WalletConnect 2.0 for its partners. NEOPIN only allows the transactions requested by the Dapps that is partnered with NEOPIN.
WalletConnect 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.
