Currently, the Realio Network App supports only the Keplr software wallet (browser extension or mobile app) and some cold storage wallets, such as Keystone. However, support for other cold storage connections, including Ledger, is still under development.
If you’re encountering issues, ensure you’re using a compatible wallet and that your software is up to date. For detailed steps on setting up the Realio Network with Keplr, follow this guide: How to Add Realio Network to Keplr/MetaMask.
