Integration of Cardano into the Houdiniswap Aggregator
Houdiniswap
ID: 69f08631d699758cde5d4a68
**Integrating Cardano Defi liquidity into Houdiniswap** We plan to integrate Cardano at the DeFi layer into the Houdiniswap aggregator, enabling both **same-chain and cross-chain swap functionality.** This initiative is designed to position Houdiniswap as a leading aggregation platform within the Cardano ecosystem. **Planned integration pathways:** **1. NEAR Intents Integration** By integrating the NEAR Intents API, we will enable cross-chain swaps for the ADA token across both EVM and non-EVM networks. This will expand interoperability while maintaining support for key native wallets (Eternl, Vespr) and additional third-party wallets supporting Cardano. **2. Minswap DEX Integration** We will integrate the Minswap API, a native decentralized exchange on Cardano, to provide users with seamless same-chain swap capabilities across a wide range of assets. This integration will support native wallets such as Eternl and Vespr, as well as selected non-native wallets. **3. Wanchain Integration** Integration with Wanchain’s API will facilitate cross-chain asset transfers from multiple EVM and non-EVM networks into the Cardano ecosystem. This pathway will further enhance liquidity access and will support both native (Eternl, Vespr) and non-native wallets. After completing these integrations, Houdini will become the number one aggregator in terms of route coverage: same-chain swaps, cross-chain swaps, and private swaps. Following that, we will focus on providing our API to top wallets and other products within the Cardano ecosystem, enabling them to leverage our API and gain access to a broad range of functionality.
Scorecard
How this score works
Each criterion is worth between 1 and 4 points. The score is the points earned out of the points on criteria that have been answered — shown as a percentage. Green is 75% or higher, Amber is 50–74%, and Red is below 50%.
Some criteria are checked automatically against the proposal data (open source, doxxed team, treasury return clauses, etc.). Others are human-judgment calls — value for money, public good, whether the deliverables are realistic. Those stay blank until a DRep ticks them.
Criteria can also be marked Not applicablewhen they don't fit the proposal — for example, "open source" doesn't apply to a DAO governance proposal with no software output. Those are excluded from the score entirely, neither helping nor hurting.
Green requires 80% coverage. If less than 80% of the applicable criteria (by points) have been answered, the verdict stays at Amber — "pending review" — even when every answered criterion passes. This proposal's coverage is currently 68% (13 of 19 applicable criteria answered).
