Kaikas

From the developer

Kaikas [Sfresso247 INC],

Kaikas is a browser extension that provides secure and usable means to interact with Klaytn network from web sites. In particular, it handles account management and connecting the user to the blockchain.
Kaikas supports Chrome on Windows, Mac, and Linux.

Account Management
Kaikas allows users to manage accounts and their keys in a variety of ways, while isolating them from the site context. This is a great security improvement over storing the user keys on a single central server, or even in local storage, which can allow for mass account thefts.
This security feature also comes with developer convenience: For developers, you simply interact with the globally available Klaytn API that identifies the users of caver-compatible browsers (caver is a JavaScript library for Klaytn network, just like web3 for Ethereum), and whenever you request a transaction signature, Kaikas will prompt the user for confirmation. It will keep the user informed. Finally, since keys are not stored centrally, attackers will attempt to phish individual users rather than performing mass hacks.

Blockchain Connection
Kaikas comes pre-loaded with nice and fast connections to the Klaytn main network and test network. It allows users to get started without synchronizing a full node, while still providing strong security.
