# About OpenFour (EN)
**OpenFour** is a modular launch engine introduced by Four.Meme.
It opens the protocol layer to external developers, teams, and communities, allowing anyone to build and deploy custom token launch modes on top of Four.Meme infrastructure.
Instead of one platform with one fixed launch model, OpenFour enables a builder ecosystem where developers can create custom bonding curve rules, trading logic, incentive systems, revenue-sharing models, and entirely new launch experiences.
All OpenFour modes are composable, on-chain, and integrated with the Four.Meme ecosystem.
Developers who pass the required security review and successfully integrate with OpenFour can earn trading incentives generated by the mode they create.
Note: OpenFour modes are modular add-ons to Four.Meme. Standard fair launches, with or without tax, remain fully supported alongside all OpenFour modes.
## Available OpenFour Modes
OpenFour currently supports four modes contributed by ecosystem partners.
### 1. GoPlus Creator Incentives
**Powered by: GoPlus Security**
GoPlus Creator Incentives is designed to reward the builders behind successful token launches.
When a token is launched through this mode, the creator’s wallet address is recorded directly within the token’s on-chain fee distribution contract. A portion of future trading fees is automatically routed to the creator without any manual claiming or off-chain distribution process.
#### **How It Works**
* Creator address is registered during token launch
* Trading fees are distributed automatically on-chain
* Creator rewards increase as the token grows
#### **Dynamic Creator Rewards**
The creator fee scales based on market capitalization:
* Starts at 0.02% during early-stage trading
* Gradually increases as market capitalization grows
* Caps at 1%
This model aligns incentives with long-term community building by rewarding creators whose projects continue to grow after launch.
### 2. GoPlus Skill Royalty
Powered by: GoPlus Security × SafuSkill
Note: GoPlus Skill Royalty is currently the only OpenFour mode that supports token tax fees.
GoPlus Skill Royalty is designed specifically for AI Skill Coins launched through SafuSkill.
Every Skill Coin comes with its own SkillRoyalty contract — a dedicated on-chain revenue vault that lives with the token and automatically distributes all trading fees.
#### **Royalty Wallet Options**
When configuring the Royalty Wallet, creators can choose between two options:
* **Custom Royalty Wallet** — Enter any wallet or contract address. Developers can deploy their own distribution contract to implement custom logic, including multi-recipient revenue sharing, auto-buybacks, holder dividends, or any other distribution mechanism. No registration or approval is required.
* **GoPlus SkillRoyaltyv1** — The official royalty vault developed by GoPlus and purpose-built for AI Skill Coins.
#### **What Makes Skill Royalty Different?**
**Fully On-Chain Revenue Vault**
Trading fees never pass through a platform-controlled treasury.
Instead, every fee is routed directly into the SkillRoyalty contract.
* No platform custody
* No multisig control
* Fully transparent and verifiable on-chain
#### **Creator Verification After Launch**
Anyone can launch a Skill Coin.
However, only the verified GitHub owner of the corresponding Skill can later bind their wallet and claim creator royalties.
This design prevents front-running and reward theft during launch.
#### Revenue Distribution
The revenue allocation is written directly into the contract and executed automatically on-chain.
| Recipient | Share |
| ---------------------------------------------- | ----- |
| Verified Creator | 70% |
| Verified Real Users (Download + Usage Tracked) | 15% |
| Ecosystem | 15% |
No manual distribution, governance vote, or off-chain promise is required.
#### Creator Incentives vs Skill Royalty
GoPlus Skill Royalty is the first mechanism launched on SafuSkill. While both GoPlus Creator Incentives and GoPlus Skill Royalty are powered by GoPlus, they serve different use cases:
#### GoPlus Creator Incentives
• Designed for general token launches
• Rewards token creators directly
#### GoPlus Skill Royalty
• Designed specifically for AI Skill Coins
• Supports royalty distribution through dedicated on-chain revenue vaults
• Supports token tax mechanisms
### 3. Likwid Dex
**Powered by: Likwid**
Likwid Dex introduces on-chain leveraged trading to tokens launched through Four.Meme.
Users can open long or short positions directly against liquidity pools without relying on order books, centralized market makers, or off-chain counterparties.
#### Why Likwid Is Different
**1. Instant Leverage on Any Token**
Likwid prices trades directly from its own liquidity pool reserves rather than external price feeds.
As a result:
* Newly graduated tokens can support leverage immediately
* No oracle integration is required
* No oracle latency or downtime
* Reduced oracle manipulation risk
**2. Unified Liquidity**
Both spot trading and leveraged trading share the same liquidity source.
There are:
* No order books
* No market makers
* No funding-rate counterparties
Trading depth scales naturally with pool liquidity.
**3. Manipulation-Resistant Design**
Likwid is designed to prevent price distortion caused by borrowing mechanics.
Leveraged positions affect price only through actual executed trades. Borrowed assets remain represented through internal mirror reserves, preventing artificial price movements.
Liquidation calculations are based on actual pool liquidity conditions rather than short-lived price spikes.
This helps create more reliable and manipulation-resistant liquidations.
**4. Dynamic Risk-Based Fees**
Trading fees increase as a trade pushes the market further away from its protected reference price.
Small Trades
* Price movement ≤ 10%
* Standard base fee applies
Large Trades
* Price movement > 10%
* Fee scales cubically with price impact
Extreme Trades
* Price movement approaches 70%+
* Fee capped at 99%
This mechanism discourages aggressive market manipulation while protecting liquidity providers.
#### Key Principle
Likwid requires neither external liquidity nor external oracles.
This enables leveraged trading on newly launched tokens immediately after graduation — something traditional oracle-based or order-book-based systems cannot easily support.
For additional technical details, please refer to the Likwid Whitepaper.
### 4. CubePeg
Powered by: Cubus × PancakeSwap Infinity
CubePeg introduces balance-based collectible Art mechanics to tokens launched on Four.Meme.
The system combines UniToken contracts with PancakeSwap Infinity Hooks to create dynamic on-chain collectibles that continue evolving after token graduation.
#### How CubePeg Works
When a token is launched as a CubePeg token:
* A dedicated PancakeSwap Infinity Hook is deployed
* The Hook is attached to the token’s V4 liquidity pool
* Every swap refreshes an on-chain random seed
* The seed powers CubePeg’s dynamic Art system
#### UniToken Art: Live Proof of Holding
Art badges are generated automatically based on token holdings.
**Minting**
For every 100,000 tokens held:
* 1 Art badge is minted
**Burning**
When a holder falls below a holding tier:
* Excess Art badges are burned automatically
**Transfers**
Art badges may move alongside transferred balances while preserving their original ID and seed.
As balances change through buying, selling, and transfers, Art badges update automatically.
#### Custom Art Rendering
Projects can provide custom renderer contracts implementing ERC-165 and IUniTokenRenderer standards.
These renderers define how CubePeg Art appears.
If no custom renderer is provided, CubePeg uses its default renderer.
#### Gas Considerations
Because Art updates occur on-chain, some transactions may consume more gas than standard ERC20 transfers.
Examples include:
* Minting Art badges
* Burning Art badges
* Moving Art badges between holders
Each transaction can mint up to 50 Art badges.
Very large purchases may require additional balance-changing transactions before all Art is fully synchronized.
Custom renderer contracts must pass CubePeg’s review and audit process before integration.
### Summary
OpenFour transforms Four.Meme from a token launch platform into an open launch ecosystem.
By opening the protocol layer to external builders, OpenFour enables developers to create entirely new launch modes while leveraging Four.Meme’s existing infrastructure, liquidity, and user base.
The current available OpenFour modes demonstrate different approaches to token creation and post-launch utility:
* **GoPlus Creator Incentives** — Creator reward infrastructure
* **GoPlus Skill Royalty** — On-chain royalty and revenue-sharing systems
* **Likwid Dex** — Oracle-free leveraged trading
* **CubePeg** — Hook-powered balance-bound Art that mints and burns live with every trade
Additional modes and mechanisms may be added to OpenFour over time as more builders join the ecosystem.
