Summary
We propose the acquisition of the Hydration (HDX) network by the Polkadot Treasury through a token conversion agreement of 1 DOT : 550 HDX, absorbing HDX into the Polkadot ecosystem over 8 quarters or earlier, with 8,000,000 DOT allocated in total. This phased integration aligns technical development and user growth (measured largely in TVL) with Polkadot’s medium-term Revive-on-Asset-Hub strategy and long-term JAM / Coreplay vision, unifying Polkadot DeFi behind its leading DeFi parachain. By deploying incentives in one defi system chain (Hydration) rather than two, this settles outstanding channel conflict between the dominant Polkadot system chain (Asset Hub) and the now dominant defi parachain (Hydration). This WFC proposal can be seen as complementary to OpenGov #1542, or in contrast to it.
Motivation
Hydration (formerly HydraDX) is one of the two most successful and operationally resilient DeFi parachains in the Polkadot ecosystem—alongside Bifrost—and leads in protocol-native liquidity, asset routing, and execution. Hydration’s architecture is modular, DOT-native, and has become Polkadot’s DeFi backbone. It is widely loved, easy to use, and has a solid team fully loyal to Polkadot.
However, Hydration has not incorporated revive, Asset Hub’s solution to programmable assets, and CoreVM+CorePlay have not matured yet to support defi applications.
This Wish-for-Change proposal represents a desire for long-term economic alignment and user growth, outlines a rough path for product development, while retiring short-term token incentives and maximizing treasury efficiency.
Why Hydration?
Among candidates such as Moonbeam/Stellaswap, Astar, Acala, Parallel, Equilibrium, and others, Hydration stands out due to:
- Native Substrate-first design, avoiding EVM dependency
- Proven leadership in XCM integration and Polkadot-native assets
- Commitment to decentralized liquidity infrastructure
- A credibly decentralized Hydration DAO
- A highly loyal and competent technical team capable of executing on Polkadot’s Coreplay/CoreVM roadmap
Hydration is already positioned as Polkadot’s DeFi hub. Other candidates have not achieved or maintained basic KPI metrics of TVL and user growth, despite being EVM-centric and “earlier” in many cases. Rather than exposing Polkadot to risk by centralizing liquidity solely in Asset Hub, this proposal recognizes Hydration as the dominant DOT-native liquidity parachain, and proposes making it a Polkadot DeFi system chain, offering:
- Technical: asynchronous (XCM) and synchronous (revive)
- Reduced defi protocol fragmentation, improving Treasury efficiency
- An optimized surface for defi incentives concentrated in Hydration
This does not in any way detract from the utility of Asset Hub, which will continue to be the home of staking, governance, and home for fungible assets (USDT, USDC, DOT, etc.) and instead supports a hybrid chain architecture. Potentially, the deployment of revive and future potential for Coreplay on Hydration may pave the way for other system chains and parachains.
Revive, CorePlay/CoreVM, and the Future of DOT Compute
The Revive project compiles Solidity contracts to the Polkadot Virtual Machine (PVM), and is slated for deployment on Asset Hub in Summer/Fall 2025. This Wish-for-Change proposal aims to have Revive also target Hydration, which would provide:
- Access to DeFi liquidity largely now concentrated on Hydration, rather than Asset Hub
- EVM address compatibility across Hydration and Asset Hub
- Seamless Solidity developer migration
Hydration’s roadmap would include:
- Integration of Revive-compatible Solidity execution in late 2025 and early 2026
- Deployment of Coreplay (or CoreVM) at scale in late 2026 to early 2027, in deep collaboration with the Polkadot Technical Fellowship to ensure success across Polkadot’s JAM Services stack for 2026–2027
It is believed the path for (1) is technically possible right now, whereas (2) requires maturation.
Proposal Details
These are initial parameter suggestions, with the total cost to the Polkadot Treasury estimated at 10MM DOT
Parameter | Value |
---|---|
Token Conversion Rate | 1 DOT : 550 HDX |
Total DOT Allocated | 8,000,000 DOT |
Duration | 8 Quarters (Q3 2025 – Q2 2027) |
Liquidity Incentives | 2,000,000 DOT/year (500,000 DOT per quarter) for DOT-native LPs and user onboarding |
Conversion Method | On-chain migration portal; managed by Hydration and Polkadot Fellowship multisig |
HDX Deprecation | Token to be sunset after final migration in Q2 2027 (Quarter 8) |
Polkadot culture prioritizes long-term sustainability. This 10 million DOT proposal (8M + 2M DOT) is exactly 2× the cost of Referendum 1542 (5M DOT), but also spans 2× the timeframe (2 years instead of 1 year), and is designed to position Polkadot DeFi for long-term success rather than short-term incentives.
If 1542 passes, the 2MM DOT incentive would be unnecessary, and this WFC should be considered for 8MM DOT only.
Through this Wish-for-Change, we welcome Hydration DAO to propose alternate parameters that better position Polkadot for even greater success. Adjusting the liquidity incentives, token conversion rate, refining product milestones, and mitigating execution risk would all be highly desirable. This should only be taken as a rough draft.
Disbursement and Milestones
Each quarter’s 1,000,000 DOT disbursement is milestone-based, tied to product deliverables and user growth KPIs:
Quarter | Period | Product Milestone | User Growth Milestone |
---|---|---|---|
Quarter 1 | Q3 2025 | DOT-HDX conversion mechanism | __,000 accounts representing __ TVL |
Quarter 2 | Q4 2025 | Revive Milestone A | __,000 accounts representing __ TVL |
Quarter 3 | Q1 2026 | Revive Milestone B | __,000 accounts representing __ TVL |
Quarter 4 | Q2 2026 | Revive Milestone C | __,000 accounts representing __ TVL |
Quarter 5 | Q3 2026 | Coreplay/CoreVM Testnet Milestone D | __,000 accounts representing __ TVL |
Quarter 6 | Q4 2026 | Coreplay/CoreVM Testnet Milestone E | __,000 accounts representing __ TVL |
Quarter 7 | Q1 2027 | Coreplay/CoreVM Production Milestone F | __,000 accounts representing __ TVL |
Quarter 8 | Q2 2027 | Coreplay/CoreVM Production Milestone G | __,000 accounts representing __ TVL |
The precise content of Revive Milestones A-C and Coreplay/CoreVM Milestones D-G, as well as TVL + account targets are intentionally left blank at present but may be refined in a follow-on “Treasurer” proposal.
Governance and Oversight
-
Formation of a Joint Migration Council:
- 5 members from the Polkadot Fellowship, qualified to oversee Revive and Coreplay/CoreVM milestones
- 3 members from Hydration DAO
- 2 non-technical members from the Polkadot community
-
Milestone verification will be based on:
- Public audits on Milestone execution by the Polkadot Fellowship
- On-chain metrics on Hydration TVL and user growth from Polkadot data ecosystem partipicants (Subscan, Dune, Parity Data, …) with Open reporting dashboards
-
Funds are disbursed quarterly via Treasury proposals upon milestone validation.
Comparison to OpenGov Referendum 1542
Polkadot OpenGov Referendum 1542 is slated to approve 5 million DOT over 1 year for short-term liquidity bootstrapping and support new Defi integrations (primarily through the “Defi bounty”). That referendum is:
- Single-year focused: Limited to 2024–2025 incentives
- Primarily reactive: Aimed at arresting DeFi liquidity decay and incentivizing usage of Polkadot through Hydration
- Non-integrated: Did not establish system-chain level strategic alignment with any one DeFi parachain
- Time-limited: Liquidity incentives were not tied to long-term product development or migration infrastructure
In contrast, this Hydration acquisition WFC proposal:
Feature | Referendum 1542 | Hydration Wish-for-Change |
---|---|---|
Total DOT | 5 million DOT | 8-10 million DOT (8M + 2M incentives) |
Duration | 1 year | 2 years |
Strategic Objective | Liquidity incentives for user growth | Strategic acquisition of Polkadot’s DeFi chain |
System Chain Integration | None | Yes — promote Hydration to DeFi system chain |
Product Milestones | Not specified | Yes — Revive, CoreVM, Coreplay roadmap gated |
DAO Coordination | Continued “lassez faire” parachain | Targeted partnership with Hydration DAO leading to acquisition |
Governance Structure | Treasury-only disbursement | Joint Migration Council (DAO + Fellowship) |
Discussion
It is believed this shifts Polkadot Treasury investment from being solely-incentive based (cf Ref 1542) to one which elevates Hydration and defi to be a key part of Polkadot strategic product roadmap.
The proposed solution is compatible with Asset Hub. Instead of continued system chain vs parachain channel conflict, business development activities can focus programmable assets in the larger TVL Hydration in 2025-206 and JAM’s Coreplay architecture in 2027 and beyond.
This is not merely a treasury spend—it is a strategic unification of Polkadot’s most advanced DeFi parachain into a key DeFi system parachain.
Rather than excluding DeFi from Polkadot’s strategic future, this proposal recognizes:
- That DeFi is central to Polkadot’s utility and user growth
- That Hydration is the best positioned project to lead it
- That Hydration can execute this vision in alignment with revive and JAM’s CorePlay service
Hydration enables:
- A single DOT-native liquidity system chain
- Developer migration via Revive and Solidity-to-PVM support
- A credible growth path into CorePlay (and/or CoreVM)
This plan retires fragmentation, eliminates channel conflict, and simplifies tokenomics—positioning Polkadot to lead the next generation of on-chain finance and trustless supercomputing with a super entrepreneurial team.
Open Technical & Governance Questions
The Hydration core team raised several important questions related to security, incentives, revenue design, and multi-chain expansion. These are addressed partly below to clarify the vision and feasibility of this proposal.
1. How do we ensure safety between Revive contracts and pallets (e.g., flash loans, oracles)?
Opening up Revive on Hydration introduces cross-context execution concerns—especially if contracts interact with liquidity pallets. To avoid flashloan-based exploits or oracle manipulation:
- Execution segmentation: Revive contracts will execute in a gated environment with limited interfaces to sensitive pallets.
- Permissioned bridging between contracts and liquidity primitives (e.g., whitelist of safe interfaces for price or liquidity updates).
- Unified oracle design: Governance-approved oracle relays or robust on-chain aggregation should be mandated for price feeds.
This complexity is acknowledged—but also solvable—using engineering principles already familiar to the Polkadot communities.
2. How are HDX holders and the Hydration team incentivized?
The current proposal provides:
- A 1 DOT : 550 HDX conversion, distributed over 8 quarters via an on-chain portal.
- A Joint Migration Council, including Hydration DAO representation, to manage roadmap delivery and funding oversight.
- A Hydration Contributor DAO could be established to:
- Allocate a portion of DOT-based liquidity incentives or core rewards
- Fund the team and contributors post-acquisition
- Operate a transitional governance process
Governance Path:
- Governance for system-level proposals will transition to Polkadot OpenGov.
- Economic and roadmap-specific governance may initially remain partially delegated to Hydration DAO, ensuring continuity and commitment during integration.
3. What happens to Hydration’s current revenue-sharing and value capture model?
Hydration currently earns fees in HDX and routes them toward liquidity providers, team funding, or DAO reserves (check?)
In the new setup:
- All protocol revenue will be DOT-denominated: swaps, bridging, or lending revenue will be routed to the Polkadot treasury.
- A revenue distribution contract governed by the OpenGov can specify:
- LP rewards
- Contributor/Team compensation
- Treasury growth mechanisms (e.g., protocol-owned liquidity)
DOT-native revenue sharing simplifies user incentives and aligns ecosystem value capture around a unified token.
4. What about Hydration’s multi-chain and multi-core expansion roadmap?
Hydration’s broader roadmap includes:
- Deploying the POL protocol and assets to external chains via Snowbridge and Hyperbridge
- Solver-based compute layers
- Expanding into multi-core JAM execution
These plans are fully compatible with this WFC and Polkadot revive + JAM’s Coreplay/CoreVM services. JAM multi-core design supports massive defi scalability. Simply put, there is zero excuse for Hydration to not use it. Bridges are DOT-aligned infrastructure, and their use will further drive cross-chain liquidity back to Hydration.
Let’s have Hydration lead Polkadot DeFi to long-term success.
