Project Overview
Hydra Launchpad is a open sourced project, integrated with top tier security features with Bonded Curve Presale Contract with live trading for users & investors. A Bonded Curve Presale Launchpad differs from a Normal Presale Launchpad primarily in how the token price behaves during the presale and the mechanics of token distribution. While both types of launchpads help raise funds for blockchain projects by allowing early investors to buy tokens before they are listed publicly, their key difference lies in the pricing model, investors benefits and incentive structure. Our platform addresses key pain points in blockchain fundraising for startups, investors, and developers.
Product Scope
-
Presale Launchpad: A simple and intuitive interface for startups to create, manage, and customize presales for their tokens, enabling projects to raise funds in a decentralized manner while ensuring transparency and fairness.
-
Bonded Curve Mechanism: The bonded curve will ensure a fair pricing structure during token presales. The curve dynamically adjusts the price based on the quantity of tokens sold, incentivizing early participation while maintaining price stability and reducing manipulation.
-
Live Token Trading: Investors can trade presale tokens in real-time, allowing for instant liquidity during the presale phase, providing a market-driven approach that benefits both the startup and the investor.
-
Security and Transparency: Hydrapad ensures transparency through decentralized smart contracts that govern token sales, reducing risks of fraud and increasing user trust. All transactions are verifiable and auditable on the blockchain.
-
Token Creation: Startups can easily create custom tokens for their projects directly through the Hydrapad platform. This feature enables the creation of tokens with predefined tokenomics, facilitating the setup of presales in a seamless and user-friendly manner.
-
Token Locking: Projects and investors can lock tokens for a defined period, enhancing trust and preventing early sell-offs. Token locking can be applied to both presale funds and tokens issued during the presale phase, ensuring long-term commitment from the project team and investors.
-
Portfolio Management for Users: Users can manage and track their investments and token holdings in a comprehensive portfolio dashboard. This feature will provide real-time updates on presale participation, token performance, and overall portfolio value, making it easier for users to monitor their assets.
-
Airdrops: Hydrapad allows users to easily conduct token airdrops as part of their marketing and community-building strategies. This feature allows projects to distribute tokens to a targeted group of users, helping to build momentum and reward loyal supporters.
-
Secure Liquidity Management: Hydrapad incorporates secure liquidity management tools, enabling projects to provide liquidity pools for their tokens and ensuring that tokens are readily available for trading. This feature also allows projects to manage the liquidity of presale funds in a secure, transparent manner, ensuring proper token flow and liquidity during the presale phase.

2. Problem Statement
Describe clearly what problem currently exists in the ecosystem and why your proposal addresses it in a timely and necessary way.
1. Limitation/Gap Identified
Creator Liquidity Crunch:
The Sandbox lacks a native, decentralized fundraising mechanism for creators to fund LAND development, game creation, or ASSET production. Current options (e.g., crowdfunding, grants) are fragmented, exclude retail backers, and fail to leverage Sandbox’s digital assets as collateral.
2. Who is Affected?
| Stakeholder | Pain Point |
|---|---|
| Creators (Indie studios, artists) | No tool to tokenize projects/ASSETs for community funding; reliant on venture capital or personal capital. |
| Players/Backers | Cannot invest early in Sandbox experiences or share in project success. |
| Sandbox DAO | Stunted ecosystem growth as creators leave for platforms with better monetization (e.g., Roblox UGC). |
| SAND Holders | Limited utility beyond transactions (no investment use cases). |
3. Consequences of Inaction
- Creators Exodus: Top talent migrates to competitors with integrated funding (e.g., Fortnite UGC + Epic Store).
- Stagnant Content Pipeline: Fewer high-quality games/experiences → declining player retention.
- SAND Utility Erosion: Token remains a transactional tool, not a growth asset, reducing long-term demand.
- Missed Web3 Leadership: Sandbox loses the “DeFi-metaverse” narrative to platforms like Decentraland.
Hydrapad’s Solution: Turning Limitations into Opportunities
| Problem | Our Fix | Sandbox Impact |
|---|---|---|
| No creator fundraising | Bonded curve presales for LAND/ASSET projects | Creators launch tokenized projects in <10 mins |
| Players can’t invest | Back projects with SAND for early tokens + rewards | Players become ecosystem co-owners |
| Dead ASSET collateral | Use ASSET NFTs as presale collateral | Unlock liquidity from 166K+ existing ASSETs |
| Low SAND utility | Presale base currency + fee burns | New demand drivers for SAND (investment/growth) |
Why Act Now?
“Without DeFi-native tools, Sandbox risks becoming a static gallery — not a thriving creator economy. Hydrapad integrates fundraising at the protocol level, turning every ASSET into a potential startup and every player into an angel investor.”
3. Proposed Solution
Explain in detail how the problem will be solved, demonstrating clarity in the technical, conceptual, and operational approach.
1. The Solution: “Sandbox Creator Fund”
A native integration enabling Sandbox creators to launch tokenized presales for projects (LAND, games, ASSETs) via bonded curves, collateralizing Sandbox NFTs for liquidity.
- Core Mechanics:
- Avatar-Gated Access: Verify eligibility via linked Sandbox avatars.
- Auto-Quest Rewards: Distribute presale tokens as quest completions in Game Maker.
2. Technologies Used
| Component | Tech Stack | Purpose |
|---|---|---|
| Smart Contracts | Solidity (EVM) + Sandbox ASSET Registry | Mint fractional tokens; enforce bonded curves |
| Identity | Sandbox Avatar ID + OAuth (Web2 login) | KYC-free whitelisting |
| Tokens | SAND (base currency) + ERC-20 (presale tokens) | Fund projects; trade rewards |
| Data Tools | GraphQL + Sandbox API | Pull ASSET metadata for collateralization |
3. Sandbox Tool Integration
| Tool | Connection to Hydrapad |
|---|---|
| Game Maker | Presale quests: “Invest 50 SAND → unlock exclusive ASSET” (auto-reward via contract) |
| Marketplace | List fractionalized ASSET tokens → liquidity for creators |
| Sandbox DAO | Governance voting on featured presales (e.g., “Project of the Month”) |
4. User Experience
Web2 Creators (No Crypto Experience)
1. Open Game Maker → Click "Fund Project"
2. Set goal: 10,000 SAND (bonded curve auto-calculates token supply)
3. Share presale link → backers pay via credit card (fiat ramp)
4. Funds unlock in SAND; backers get tokens + wearable badge
Web3 Creators/Backers
1. Connect Sandbox avatar → see eligible presales
2. Stake ASSETs as collateral → mint presale tokens
3. Trade tokens live during presale (bonded curve adjusts price)
4. Post-presale: Tokens auto-list on Marketplace or convert to liquidity pool
5. Why This Solution Fits Sandbox
| Problem | Hydrapad’s Solution | Unique Advantage |
|---|---|---|
| Creators lack funding | Tokenize ASSETs → community-powered presales | Turns inactive NFTs into liquidity |
| Players can’t invest early | SAND-denominated curves → micro-backing ($5+) | Makes everyone an angel investor |
| SAND utility limited | Base currency for presales + fee burns | New demand sink → deflationary pressure |
| Fragmented tool experience | Native Game Maker/Marketplace hooks | No new apps → works inside Sandbox ecosystem |
Why This Wins:
“Hydrapad doesn’t just plug into Sandbox — it turns your ecosystem into a self-sustaining creator economy. By collateralizing ASSETs, we unlock trapped value; by using SAND curves, we fuel tokenomics; and by embedding in Game Maker, we make DeFi native to the metaverse.”
Grant Impact: $25k funds the ASSET fractionalization engine and Game Maker SDK integration

3. Contract Architecture & Tools
| Component | Solution | Purpose |
|---|---|---|
| Bonded Curves | Custom EVM contracts | SAND-denominated pricing: P(S)=a×S^b |
| ASSET Wrapper | Sandbox Registry-integrated | Fractionalize NFTs → ERC-20 tokens |
| Fiat Onramp | Transak API | Credit card presales for Web2 creators |
| Quest Verification | Sandbox Game Maker Events | Auto-distribute tokens on quest completion |
4. Infrastructure Requirements
| Layer | Technology | Sandbox Sync |
|---|---|---|
| Smart Contracts | Solidity (ETH/Polygon focus) | Sandbox ASSET Registry hooks |
| Backend | Node.js + Sandbox API | Live quest completion monitoring |
| Data Indexing | The Graph (Sandbox subgraph) | Track presale KPIs |
| Storage | IPFS (NFT metadata) + Arweave (immutable logs) | VoxEdit asset preservation |
5. In-Game Experience Integration
Flow: Creator Launching Presale
Player Benefits:
- Trade fractional ASSET tokens during live presales
Technical Validation
ASSET Collateralization Formula
For an ASSET valued at 1,000 SAND:
Tokens minted = (ASSET_value × Curve_multiplier) / Initial_price
Where:
- Curve_multiplier = 10 (for fractionalization)
- Initial_price = 0.01 SAND/token
Output:
10,000 tokens minted → presold via bonded curve
Why This Aligns Perfectly
“Hydrapad transforms Sandbox into a self-funding metaverse economy: Creators monetize idle ASSETs, players become micro-investors via quests, and SAND gains utility as the reserve currency. Our Game Maker integration makes this frictionless - no new tools required.”
