**Short description**: Maintenance of Ledger Apps for Polkadot, Kusama, Statemine and Statemint. 

**Project Category/Type:** Software development

**Previous treasury proposals**: none

## Overview and Context

Zondax has created and currently maintains the Polkadot, Kusama, Statemine, and Statemint Ledger Apps, which offer users a secure and effortless way to interact with the substrate chains mentioned using their Ledger devices.
 
Maintenance has been funded by the Web3 Foundation until now. The current contract expires at the end of June 2023. For the sake of continuity and to promote further decentralization, we are glad to request funding to the treasury to continue our services.

Our goal with this proposal is to enhance the apps functionality and ensure its continuous compatibility with runtime upgrades and major modifications. We are committed to delivering a high-quality Ledger app that meets the evolving needs of the community.

- [Statemine](https://github.com/Zondax/ledger-statemine) 
- [Statemint](https://github.com/Zondax/ledger-statemint) 

In order to keep the apps up to date, every time there is a breaking upgrade development work is required and a security code audit review is conducted before any new release. These steps are crucial before the official release of the upgraded version in Ledger Live.


Most of our contributions to the blockchain ecosystem can be found in our [GitHub organization](https://github.com/zondax): 

Over the last few years, Zondax has been involved in a large number of projects for most of the key players in the blockchain industry. For this reason, we are confident that we can provide a long term commitment.

## Proposal objectives

Our goal with this proposal is to enhance the app functionality and ensure its continuous compatibility with runtime upgrades and major modifications. We are committed to delivering a high-quality Ledger app that meets the evolving needs of the community.

In order to keep the Ledger apps up to date, every time there is a breaking upgrade development work is required and a security code audit review is conducted before any new release. These steps are crucial before the official release of the upgraded version in Ledger Live. 

The secure code audit used to be conducted by Ledger, however today, in order to be listed on the Ledger Live “My Ledger” section, all embedded apps must go through an integration process that includes a security audit performed by one of the selected trusted partners of Ledger as stated in their [developer portal](https://developers.ledger.com/docs/embedded-app/security-audit/)
