[Campaign Category] Category Questions

Describe what makes your idea innovative compared to what has been previously launched in the market (whether by you or others).

AnyToAny will be a example of what can be built on top of VIA Labs’ VIA Network, the cross-chain interoperability layer VIA is finalizing on Cardano. AnyToAny is unique because it leverages both swapping and aggregation: projects that go cross-chain with VIA Labs are natively added into AnyToAny, but AnyToAny is also flexible. Projects or protocols that opt for different cross-chain solutions can still be aggregated through AnyToAny, making it a universal liquidity layer that DeFi users and protocols can leverage to swap between EVM and Cardano ecosystems. Other existing protocols do NOT have this kind of cross-chain aggregation and do not offer the same flexibility (speed, security) to integrating parties.

Describe what your prototype or MVP will demonstrate, and where it can be accessed.

This grant will enable an advanced mainnet MVP for AnyToAny including a "Universal Frontend" for cross-chain tokens hosted by VIA Labs.

The final product will demonstrate a live swap from an EVM mainnet (ETH, Base, Avax, etc.) to Cardano mainnet.

Transaction Flow:

Assume the user has USDC on Base and wants to swap into cross-chain memecoin X on Cardano

• The system swaps USDC -> ETH -> memecoin X (via its EVM Aggregator).
• The system bridges memecoin X (Base) -> memecoin X (Cardano)

As low-slippage cross-chain liquidity routes become available, AnyToAny will have the tooling to route through those specific routes.

This will be able to be accessed from a public URL (e.g., cardano-pilot.anytoany.io) and a GitHub repo for the integration contracts.

Describe realistic measures of success, ideally with on-chain metrics.

• Volume: >$100,000 USD in cross-chain volume routed to Cardano tokens within the first 3 months of Mainnet beta.
• Integrations: Successful API binding with at least 1 major Cardano DEX Aggregator and 1 major EVM Aggregator.
• Token Support: "Whitelisting" of at least 5 top Cardano assets (e.g., SNEK, WMT, AGIX) available for purchase from EVM chains on Day 1.
• Speed: End-to-end cross-chain swap completion in <3 minutes (constrained by Cardano block times, but optimized).

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

The Problem: Cardano liquidity is trapped. EVM users find it too hard to buy Cardano tokens.

The Solution: An aggregation router that connects the two worlds.

This can be broken down into three simple steps:

1. EVM Aggregation: AnyToAny will scan leading EVM DEXs to get the best price for the user's input token (e.g., PEPE on ETH) into the bridgeable asset.
2. VIA Transport: AnyToAny will use VIA's secure message passing to move the value to Cardano. Routing through the cross-chain token itself (if its on both chains already) OR an optimal bridging token (usually stablecoins)
3. Cardano Aggregation: We trigger a smart contract on Cardano that utilizes local liquidity (e.g DEXHunter/MinSwap) to buy the specific asset the user requested. This removes the "Bridge Dilemma" where users have to manually hop between 4 different dApps just to buy one token.

[Your Project and Solution] Impact

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

• New Capital Inflows: This is a direct pipe for EVM capital to enter Cardano. It lowers the barrier to entry for retail investors who want exposure to Cardano ecosystem tokens but have been reluctant to learn the Cardano ecosystem. AnyToAny puts everything in one place for these users.
• RWA Utility: Real-World Asset projects can use AnyToAny to enable purchases from other blockchains into Cardano -- increasing their addressable market.
• DEX Volume: By routing orders through Cardano DEX aggregators, AnyToAny generates fee revenue for the entire underlying Cardano DeFi stack (LPs & Aggregators).

[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?

VIA Labs is a cross-chain intereropabilty protocol that has been building for 4+ yeras. We've sent over 20M cross-chain messages, and are live on over 140 different blockchain ecosystems. We're working in collaboration with the Midnight Foundation to enable cross-chain messaging between Cardano & Midnight and have successfully demonstrated this at the Midnight Summit in London (Nov 2025). See the video link here: https://www.youtube.com/live/1vphhGXf5VA Fast forward to 17:20 for the start of the presentation and 27:00 for the demo itself.

Outside the Cardano ecosystem, our team has received grants from titans in the space such as Circle, Avalanche, and Stellar to expand cross-chain interoperability to those ecosystems or build out novel products. For example, VIA Labs was the first protocol to deploy Circle's Bridged USDC Standard and worked with them to develop their methodology for approving github requests. We've also gracefully tied to together Avalanche's built-in cross-chain messaging platform, ICM, with Circle's CCTP, demonstrating our expertise at working on external (non-VIA) cross-chian messaging solutions and tying them together with VIA products.

[Final Pitch] Value for Money

How does the cost of the project represent value for the Cardano ecosystem?

The relative ask is low compared to what has already been built and the expertise our team is bringing to Cardano. The hardest part of any integration is getting the VIA Network itself deployed and battle-tested. Because VIA is already working with Midnight to enable cross-chain connectivity between Midnight and Cardano, most of the heavy lifting and core infrastructure cost for bringing VIA to Cardano has already been absorbed outside of this proposal. VIA has spent years, along with non-Cardano grant support, building and hardening this cross-chain infrastructure; we’re not asking Catalyst to fund that again.

This proposal is specifically for the Cardano-facing work required to make AnyToAny a practical, ecosystem-wide tool: Cardano routing, integrations with Cardano and EVM DEX aggregators, the universal front-end, SDKs, documentation, testing, and a focused security review. That work directly benefits the entire ecosystem. DeFi users get a simple routing platform to move into and trade within Cardano without juggling multiple bridges and UIs. Protocols get a clear path to go cross-chain and list their tokens so users can actually trade them. DEX aggregators on Cardano gain additional routed volume through their existing liquidity, rather than competing with a new silo. Even other cross-chain protocols benefit: if they have deep, reliable pools, the AnyToAny router can choose their liquidity when it produces the best route.

In short, funding AnyToAny is funding the Cardano integration layer on a proven cross-chain engine, turning it into reusable public infrastructure for the ecosystem.
