I'm glad to announce that the version 0.4 of Kondor Wallet is ready and published. This new version is an extensive work to manage multiple addresses derived from a single seed phrase.

**You can install the new version here: [Kondor extension - Google Chrome](https://chrome.google.com/webstore/detail/kondor/ghipkefkpgkladckmlmdnadmcchefhjl)**

For new readers, Kondor is a browser extension to interact with Koinos blockchain, like metamask in ethereum, or keychain in hive.

## Seed phrase
![](https://lh3.googleusercontent.com/7h4SiDDd2MSlBXJxFDYFNhfSA8qrUij_b3MZFcjwbahqM2z7bux-pSJBBgDFODzAktmHh8HNQItzSigssvEwyVpflw=w640-h400-e365-rj-sc0x00ffffff)

The seed is a phrase of 12 words (secret) that can be used to generate multiple addresses. Kondor introduces this seed by following the [BIP32](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki), [BIP39](https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki), and [BIP44](https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki) standards.

Since the standard BIP44 support multiple blockchains from a single seed, it requires a [unique identifier](https://github.com/satoshilabs/slips/blob/master/slip-0044.md) for the blockchain. Kondor uses the number 659 for koinos. This value was selected by taking the word "koinos", converting it
to ascii [107 111 105 110 111 115], and adding their values.

# Koilib 4
This version is also compatible with [Koilib 4](https://github.com/joticajulian/koilib/releases), which introduces changes in the ABI in order to get a little closer to the goal of using a single ABI for both web and koinos CLI.

The previous version Koilib 3 is also supported. This help apps, like [koindx.com](koindx.com), to have a smooth transition while they update their webpages.

# Accounts and Signers
Kondor differentiate 2 types of addresses derived from a seed phrase: Accounts and Signers.
The **Accounts** are addresses derived with the objective of storing assets, like koins, tokens or NFTs. So, a typical address.
The **Signers** are addresses linked to a single account. The idea behind this new concept is to prepare the path for the smart contract wallets.

(for more details check [HDKoinos](https://github.com/joticajulian/kondor/blob/v0.4.0/src/ts/HDKoinos.ts))

As you probably saw in my previous post, I already finished [the first version of a smart contract wallet for koinos](https://peakd.com/koinos/@jga/smart-contract-wallet). Kondor doesn't have smart contract wallets. However, it introduces the different parts required to create webapps dedicated to smart contract wallets. My next objective is to create this webapp in order to show the different features that the whole community would gain by adopting this type of wallets 🚀

Kondor is open source, you can check the code here: https://github.com/joticajulian/kondor/tree/v0.4.0
