YelFI Whitepaper
Yellow Finance Meets Real-World GPU Infrastructure
Version 1.0 • October 2025
#Abstract
YelFI introduces a revolutionary DeFi ecosystem that bridges blockchain technology with physical GPU infrastructure. By tokenizing real-world computing assets and distributing revenue through on-chain mechanisms, YelFI creates a transparent, efficient marketplace where investors gain fractional ownership of GPU resources while earning passive income from compute rentals and mining operations. Our custody NFT system ensures verifiable ownership and automated reward distribution through smart contracts and oracle integration.
Table of Contents
1. Introduction
The global demand for GPU computing power has exploded with the rise of artificial intelligence, machine learning, cryptocurrency mining, and high-performance computing applications. However, access to GPU infrastructure remains centralized, expensive, and inefficient for both providers and consumers.
YelFI solves this by creating a decentralized marketplace where:
- GPU owners can tokenize their hardware and raise capital
- Investors gain fractional ownership of high-value computing assets
- Revenue from GPU rentals is automatically distributed on-chain
- Custody NFTs provide verifiable proof of ownership and rights
- Oracles ensure transparency in hardware performance and earnings
2. The Problem
High Barrier to Entry
Enterprise-grade GPUs (RTX 4090, A100) cost $2,000–$15,000 each, making it difficult for small investors to participate in the GPU economy.
Lack of Transparency
Traditional GPU rental platforms operate as black boxes with no visibility into actual hardware utilization, uptime, or revenue distribution.
Inefficient Capital Allocation
GPU owners often lack the capital to scale operations, while investors have no access to this high-yield asset class.
No Fractional Ownership
Current models require full ownership of hardware, preventing diversification and limiting liquidity.
3. YelFI Solution
YelFI creates a comprehensive DeFi ecosystem that combines token launches, NFT-based custody, and automated revenue distribution to democratize access to GPU infrastructure.
Token Launch
Launch $YELFI tokens via Four.Meme's bonding curve to raise initial capital for GPU acquisition.
Custody NFTs
Issue tiered NFTs to investors that certify ownership rights and determine revenue share percentages.
Oracle Integration
DIA oracles provide real-time telemetry on GPU performance, uptime, and earnings validation.
Revenue Splitter
Smart contracts automatically distribute rental income to NFT holders based on ownership stake.
4. Token Launch on Four.Meme
What is Four.Meme?
Four.Meme is a no-code launchpad on BNB Chain that enables token creation through bonding curves and automatic liquidity provisioning on PancakeSwap. This provides:
- Fair launch mechanism with no pre-sale advantage
- Automated market making through bonding curves
- Instant liquidity when funding targets are met
- Community-driven price discovery
YelFI Launch Parameters
90% Community Allocation: All tokens available through fair launch bonding curve on Four.Meme
10% Team & Dev: Locked 12 months, vested over 24 months
Operational Flow
Token Deployment
Configure bonding curve parameters on Four.Meme dashboard and deploy $YELFI token contract.
Public Sale
Community purchases tokens through the bonding curve interface. Price increases with demand.
Liquidity Provision
When hard cap is reached, Four.Meme automatically pairs tokens + BNB into PancakeSwap liquidity pool.
NFT Distribution
Backend relayer monitors purchase events and airdrops Custody NFTs to qualified investors.
5. Custody NFT System
Custody NFTs (ERC-721 standard) serve as verifiable proof of investment and determine revenue distribution rights. Each NFT contains on-chain and IPFS-hosted metadata linking to legal custody agreements.

}6. GPU Tokenization Architecture
Physical GPUs are tokenized through a multi-layer system combining on-chain NFTs, off-chain telemetry, and oracle-verified data feeds.
Architecture Components
Physical Layer
GPU hardware with unique serial numbers hosted in verified data centers with attestation agents.
Attestation Agent
Custodian-run software that monitors GPU status (uptime, temperature, utilization) and cryptographically signs telemetry reports.
DIA Oracle
Aggregates telemetry from multiple custodians and publishes standardized on-chain data feeds (GPU:serial:utilization, GPU:serial:earnings).
Asset NFT Contract (ERC-721)
Each physical GPU = one NFT with on-chain metadata pointer. Mintable only by verified custodians.
Fractional Vault (ERC-20)
Optional: locks Asset NFT and mints fungible shares (e.g., 1M shares per GPU) for fractional ownership.
Revenue Splitter Contract
Collects rental payments and mining rewards. Distributes pro-rata to vault token holders or NFT owners.

}7. Revenue Distribution Model
Revenue Sources
GPU Rentals
Hourly/daily compute rentals for AI training, rendering, and development
Mining Operations
Cryptocurrency mining during idle periods (ETH, ETC, RVN)
Marketplace Fees
Trading fees from NFT secondary market transactions
Distribution Flow
Revenue Collection
Project treasury receives payments from GPU rentals and mining rewards into the RevenueSplitter contract.
Oracle Verification
DIA oracle validates revenue amounts against actual GPU usage telemetry to prevent fraud.
Share Calculation
Smart contract calculates each NFT holder's share based on tier multiplier and ownership percentage.
Claim Process
NFT holders call claim() function to withdraw their accumulated rewards in USDT or BNB.
Example Calculation
GPU generates $100/day in rental income:
- • Bronze NFT holder (0.1%, 1.0x multiplier): $0.10/day
- • Silver NFT holder (0.5%, 1.2x multiplier): $0.60/day
- • Gold NFT holder (1.0%, 1.5x multiplier): $1.50/day
8. Technical Implementation

CustodyNFT (ERC-721)
Non-fungible tokens representing investment tiers with metadata links to custody agreements and IPFS.
AssetNFT (ERC-721)
Represents individual physical GPUs. Minted only by verified custodians with attestation signatures.
FractionalVault (ERC-20)
Locks AssetNFTs and mints fungible shares for fractional GPU ownership and trading.

11. Legal & Compliance
YelFI operates with full legal compliance and transparency:
Corporate Structure
YelFI is operated by YelFI Ltd., a registered entity in British Virgin Islands, acting as the legal custodian and project operator. All hardware assets are owned by the company and tokenized for investor participation.
Securities Compliance
Custody NFTs may be classified as securities in certain jurisdictions due to revenue-sharing rights. YelFI implements KYC/AML procedures for investors and restricts sales in prohibited jurisdictions (USA, China).
Custody Agreements
Each NFT links to a legally binding custody agreement hosted on IPFS that defines:
- Investor rights and obligations
- Revenue distribution mechanics
- Insurance and liability terms
- Dispute resolution procedures
- Redemption and exit options
Audits & Transparency
All smart contracts are audited pre-deployment. Financial statements and GPU performance reports are published quarterly. On-chain treasury wallets are publicly visible.
Insurance & Risk Management
Hardware insurance covers theft, damage, and custodian default. 10% of revenues are allocated to an on-chain insurance reserve managed by DAO governance.
12. Conclusion
YelFI represents a paradigm shift in how GPU infrastructure is financed, owned, and monetized. By combining DeFi token launches, NFT-based custody systems, and oracle-verified revenue distribution, we create a transparent, efficient marketplace that benefits all stakeholders:
- Investors gain fractional ownership of high-yield computing assets with automated passive income
- GPU Owners access capital to scale operations without diluting ownership
- Renters benefit from competitive pricing and transparent performance metrics
- The Ecosystem grows through community governance and decentralized decision-making
