[Campaign Category] Category Questions

Mention your open source license and describe your open source license rationale.

Apache 2.0 was chosen because it is a permissive and business-friendly license, widely adopted across the open-source ecosystem, and it provides legal clarity with explicit patent protection for contributors and users

How do you make sure your source code is accessible to the public from project start, and people are informed?

The repository will be public from day one, with all development activity shared transparently. Updates will be announced through public channels, and a dedicated Discord channel will allow direct community interaction.

How will you provide high quality documentation?

A comprehensive public documentation site will be maintained, including user guides, developer references, and contribution guidelines, following the same high standards established in TxPipe’s previous open-source projects.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

Problem Statement

Blockchain and crypto can already do a lot, it’s time to show the world how they offer better alternatives to the status quo in many traditional industries, by applying them to boring operational challenges in everyday business use cases.

Digital commerce, in particular, is one of Web2’s most mature and widely adopted sectors, yet blockchain integration has mostly been limited to payment gateways or niche experiments. This is an open opportunity for Cardano to prove its value in mainstream, high-volume, multi-party, trust-heavy environments.

To unlock this potential, solutions must be blockchain-first by design while keeping blockchain as the underlying infrastructure rather than the sole purpose. Patching legacy platforms with isolated blockchain features will never deliver the depth of integration, trust guarantees, and interoperability achievable when capabilities are considered from the start.

Proposed Solution

This end goal is to create a low-code platform for launching live digital commerce stores, purpose-built to harness Cardano’s strengths. It will enable anyone, without blockchain expertise, to deploy stores with native crypto settlement, on-chain invoicing, on-chain order tracking, and tamper-proof traceability records in a way traditional systems cannot match.

We acknowledge that building a full-blown solution of this magnigute is outside the scope allowed by this category budget. Nevertheless, we are confident that we can build a functional proof-of-concept that developer teams in the community can use as template for more advanced solutions.

Scope

We divide development of the proof-of-concept into distinct set of features: basic and advanced. This separation allows us to have early releases with end-to-end functionality.

Basic Features:

• White-label store frontend: Simple front end for users to navigate and purchase items from a dynamic catalog.
• Store creation back-office: Simple back-office for sellers to create and manage their online stores.
• crypto-first checkout: A checkout experience tailored for payments using ADA, stablecoins or Cardano-native assets.

Advanced Features:

• Escrow contracts: On-chain smart contract for payment escrow triggered by shipping events (Oracle system is out-of-scope).
• Verifiable order status and events: Immutable records of invoices, orders, shipping, and payments.
• Seller / Buyer reputation & ratings : On-chain tracking system for reputation of sellers and buyers.

[Your Project and Solution] Impact

Please define the positive impact your project will have on the wider Cardano community

Simplifies launching blockchain‑first commerce stores, showcasing Cardano’s value in mainstream industries and creating practical adoption paths. Enables on‑chain payments, tracking, and reputation systems; lowers adoption barriers; expands the builder base; strengthens connectivity with other Cardano services; and drives network adoption.

[Your Project and Solution] Capabilities & 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?

TxPipe is an active member of the Cardano ecosystem

TxPipe has been developing open-source tools for the Cardano ecosystem for over 2 years and we're not going anywhere. Evidence of our commitment can be found by evaluating the continuous activity of our public code repositories.

Experience developing in the Cardano ecosystem

TxPipe has helped developed several dApps for the Cardano ecosystem. This experience allows us to evaluate the feasibility of the project and its potential benefit from a developer's perspective.

Successful Catalyst proposals

We have successfully completed several Catalyst proposals. This may serve as evidence that our team has the required capabilities to fulfill these type of projects.

Development process will be public and open-source

Both the output and the development process will be public and open-source. This approach provides an easy way for the Catalyst team and the Cardano community to evaluate the progress at each step of the process.
