How Svalinn works

In order to send a transaction, you need to sign it beforehand using your private key so you can prove you own the funds deposited on the wallet associated with your private key. Once the transaction is signed, it is ready to be sent to the ICON nodes so they can validate and process it. Even if your online computer gets infected by malware, there is cryptographically no way to recover a private key from a signed transaction, so your private key remains safe.

Based on Electron and the official ICON-SDK-JS, Svalinn is capable of transaction signing on an offline device. Svalinn saves the signed transaction to a file and transfers it to an online device before sending it. This enables your private key to always stay on an offline device without exposure to the Internet when making transactions.

As a picture is worth a thousand words, here’s how it works schematically:
