First, let’s start with an overall understanding of what the proposal is about:

Overview: The Cardano Ledger Live integration proposal aims to secure funding for the next 12 months to maintain and update the open-source codebase that enables seamless integration of ADA and native assets into Ledger Live. This integration was initiated through a collaborative effort involving the Cardano Foundation, Cardano Ambassadors, Strica, and Ledger. The project’s previous phases have successfully integrated ADA management and staking on the Cardano Blockchain through Ledger Live, benefiting thousands of Ledger users.

Purpose: The proposal’s primary goal is to address the challenge of sustaining the Cardano-Ledger Live integration by obtaining funding for professional maintenance, bug fixing, and updating capacity. This maintenance is essential to ensure that Cardano asset holders can continue using Ledger Live to manage their ADA holdings efficiently.

Project Background based on the interview with Ashis:

The project’s collaboration began during Catalyst Fund 7, and it has continued through Fund 9 with integrating Staking. Strica has been maintaining the open-source code for the Cardano-Ledger Live integration. The responsibility for maintaining blockchain integrations with the Ledger platform lies with the respective blockchains. Thus, securing funding for the Cardano-Ledger Live integration is essential to maintain its seamless operation for the Cardano community.

The project has faced several challenges and complexities in its journey. One of the significant hurdles was encountered during the implementation of Cardano staking inside Ledger Live (Fund 9). The original proposal aimed to integrate staking by a certain timeline, but unforeseen developments arose, leading to delays and additional work.

The team successfully completed the integration of staking into Ledger Live six months before the proposed deadline, but Ledger’s internal changes posed a challenge. Ledger decided to transition their entire ecosystem from JavaScript to TypeScript, requiring a rewrite of the existing JavaScript code to TypeScript. This task was beyond the scope of the original proposal, and it meant additional efforts and resources were needed.

The team faced a dilemma as it was difficult to seek additional funds. Hence, the team decided to take the initiative and invested their own resources and time to rewrite the integration in TypeScript. Despite not seeking external funding, they aimed to deliver the integration successfully.
