## Abstract

This specification describes how Status relates with EIPs.

## Introduction

Status should follow all standards as possible.
Whenever the Status app needs a feature, it should be first checked if there is a standard for that,
if not, Status should propose a standard.

## Components

### BIP32 - Hierarchical Deterministic Wallets

Support: Dependency.  
[Reference](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki)
Description: Enable wallets to derive multiple private keys from the same seed.  
Used for: Dependency of BIP39 and BIP43.  

### BIP39 - Mnemonic code for generating deterministic keys

Support: Dependency.  
[Reference](https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki)
Description: Enable wallet to create private key based on a safe seed phrase.

### BIP43 - Purpose Field for Deterministic Wallets

Support: Dependency.  
[Reference](https://github.com/bitcoin/bips/blob/master/bip-0043.mediawiki)
Description: Enable wallet to create private keys branched for a specific purpose.

[Source code](https://github.com/status-im/status-mobile/blob/develop/src/status_im/constants.cljs#L240)
Observation: BIP44 don't solve privacy issues regarding the transparency of transactions, therefore directly connected addresses through a transactions can be identifiable by a "network reconnaissance attack" over transaction history, this attack together with leakage of information from centralized services, such as exchanges, would be fatal against the whole privacy of users, regardless of BIP44.
