[GENERAL] Summarize your solution to the problem (200-character limit including spaces)

Add support for Marlowe contracts, its Datum on Cardanoscan, allowing tracing and verifying contracts on the chain easily. Providing transparency and ease of access to on-chain data.

[GENERAL] Does your project have any dependencies on other organizations, technical or otherwise?

No

[GENERAL] If YES, please describe what the dependency is and why you believe it is essential for your project’s delivery. If NO, please write “No dependencies.”

No dependencies

[GENERAL] Will your project’s output/s be fully open source?

No

[GENERAL] Please provide here more information on the open source status of your project outputs

Cardanoscan is a closed-source project and hence this feature ad-on will also remain closed-source.

[SOLUTION] Please describe your proposed solution.

Tracing Marlowe contracts is challenging due to the complexity of multiple transactions and involved parties in the contract execution. Marlowe contracts operate based on a set of Plutus contracts, and by decoding transactions related to Marlowe Plutus contracts, we can extract valuable information for effective tracing and viewing of Marlowe contracts.

In response, we plan to enhance Cardanoscan by incorporating Marlowe contract listing, datum decoding, code view, and contract tracing features. This upgrade aims to provide users, as well as Marlowe contract developers, with a user-friendly interface for seamless viewing, debugging, and tracing of transactions within the Cardano ecosystem. This solution not only addresses the intricacies of Marlowe contracts but also contributes to the broader accessibility and transparency goals of the Cardano platform.

[IMPACT] Please define the positive impact your project will have on the wider Cardano community.

Cardanoscan streamlines admission into the Cardano ecosystem by providing a dependable and feature-rich interface, attracting new projects and fostering innovation. It enables both novice and professional developers to track their transactions and successfully interact with the network. The happening inclusion of new features based on community feedback expands the platform's appeal and contributes to the Cardano ecosystem's growth.

The Marlowe support on Cardanoscan will provide ease of access and transparency for transactions. Cardanoscan has encouraged the construction of creative projects and nurtured a healthy developer community within the Cardano ecosystem by providing access to key network information and tools. The Marlowe support in Cardanoscan's offerings will be critical in increasing acceptance and adding to the Cardano blockchain's overall development and success.

[CAPABILITY & FEASIBILITY] What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

We have a proven track record of successfully completing projects while maintaining high levels of trust and accountability. Since the beginning of the Shelley period, our team has been actively participating in the Cardano ecosystem, and we have successfully developed and maintained Cardanoscan, a widely used Cardano explorer.

In addition to Cardanoscan, we created Typhon Wallet, a highly recognised and user-friendly wallet that has received widespread acclaim from the Cardano community. This wallet is a direct result of our involvement in the Catalyst programme, which demonstrates our dedication to innovation and providing important community solutions.

We have also worked and delivered the Cardano ADA, Native tokens, and ADA Staking integration within Ledger Live bringing the mass userbase of Ledger to Cardano and providing a safe and secure custodial wallet solution to the community.

Furthermore, we have contributed to the Cardano ecosystem through a number of open-source libraries, which can be found on our GitHub repository (https://github.com/StricaHQ). These libraries represent our commitment to providing developers with dependable tools and resources that conform to high-quality and transparent requirements.

Our experience, knowledge, and positive feedback from the community attest to our ability to deliver projects with a strong emphasis on integrity and responsibility. We intend to uphold these values throughout the course of our implementation.
