NFT Finance (NFT-Fi)

Allows NFT holders to use their assets as collateral to borrow fungible tokens (e.g., ETH, stablecoins) without selling. This unlocks liquidity from otherwise idle assets. Protocols use peer-to-pool (e.g., NFTfi, BendDAO) or peer-to-peer (e.g., Arcade) models to facilitate loans.

• Key Mechanism: Over-collateralization, loan-to-value (LTV) ratios, and liquidation auctions protect lenders.
• Example: A Bored Ape holder borrows 30 ETH against their NFT to pay expenses, repaying the loan plus interest to reclaim their collateral.

The process of dividing ownership of a single high-value NFT into multiple fungible tokens (often called shares or F-NFTs). This lowers the entry price for investors and creates a liquid market for partial ownership.

• Key Mechanism: A vault (smart contract) holds the NFT and mints ERC-20 tokens representing fractional ownership.
• Examples: Platforms like Fractional.art (now Tessera) and Unic.ly enable collective ownership of blue-chip NFTs, allowing trading on decentralized exchanges.

Financial contracts that allow users to speculate on the future price of NFTs or collections without owning the underlying asset. This provides leverage and hedging opportunities.

• Key Products: Perpetual futures (e.g., NFTPerp) track collection floor prices. Options and index tokens (e.g., NFTX vault indices) offer exposure to broader market segments.
• Purpose: Enables sophisticated trading strategies and risk management for NFT market participants.

Enables temporary, permissioned transfer of NFT utility without transferring ownership. This is critical for play-to-earn gaming and metaverse access.

• Key Mechanism: Smart contracts facilitate a lease agreement where the renter gains usage rights (e.g., in a game) for a fee, while ownership and primary control remain with the lender.
• Examples: Protocols like reNFT and IQ Protocol allow gamers to rent NFT characters or land, lowering the barrier to entry for blockchain games.

Infrastructure that provides reliable, on-chain price feeds for NFTs, which is essential for undercollateralized lending, accurate liquidations, and derivative pricing.

• Key Methods: Use time-weighted average prices (TWAPs), trait-based valuation models, and aggregated marketplace data.
• Examples: Upshot and Abacus provide appraisal and spot price data that DeFi protocols consume to determine NFT collateral value.

Automated Market Makers (AMMs) and liquidity pools designed specifically for NFT-fungible token pairs or NFT-NFT swaps. This solves the inherent illiquidity of NFT markets.

• Models: Constant Function Market Makers for NFT/ETH pools (e.g., Sudoswap), Proactive Market Makers (PMM) for improved capital efficiency.
• Benefit: Provides continuous, permissionless liquidity, allowing instant buys and sells at algorithmically determined prices.

Financial instruments that provide the right, but not the obligation, to buy (call) or sell (put) an NFT at a predetermined price before a set expiry. NFT vault strategies automate complex positions, allowing users to earn yield by:

• Covered Calls: Depositing an NFT and selling call options against it to generate premium income.
• Put Selling: Selling put options to earn premiums, with the obligation to buy the NFT at the strike price if exercised.
• Delta-Neutral Strategies: Hedging market direction risk to profit from volatility or funding rates. These strategies turn idle NFTs into yield-generating assets.

A model that enables temporary, permissioned use of an NFT without transferring ownership. This is crucial for utility-based NFTs in gaming, membership, or virtual land. Implementations use smart contract wrappers or delegation mechanisms to grant time-limited access rights. Use cases include:

• Gaming: Renting a powerful in-game asset for a specific tournament or season.
• Metaverse: Leasing virtual land or property for a defined event period.
• Membership: Granting temporary access to a token-gated community or service. Payments are typically made in fungible tokens for the rental period.

NFT-Fi introduces unique risks stemming from the nature of the underlying collateral. Key challenges include:

• Oracle Risk: Dependence on price oracles for liquidations and indexes; manipulation or failure can cause systemic issues.
• Illiquidity & Volatility: NFT markets can be thin, leading to sharp price drops and difficult liquidations.
• Collateral Valuation: Appraising unique assets is subjective and complex, leading to unreliable Loan-to-Value (LTV) ratios.
• Smart Contract Risk: Exploits in lending or fractionalization protocols can lead to total loss of locked NFTs.
• Legal & Regulatory Uncertainty: Evolving frameworks around fractionalized securities and derivatives.

NFT-Fi protocols rely on price oracles to determine collateral values for lending, fractionalization, and derivatives. These oracles can be manipulated through wash trading or exploiting low-liquidity markets, leading to inaccurate valuations. A manipulated floor price can allow users to borrow excessively against overvalued NFTs or trigger unfair liquidations. Protocols mitigate this with time-weighted average prices (TWAPs), multi-source data aggregation, and circuit breakers.

The core risk is smart contract vulnerability. Bugs in lending pools, AMMs for NFT fractions, or derivative contracts can lead to direct fund loss. Key vulnerabilities include:

• Reentrancy attacks on payment logic.
• Logic errors in loan-to-value (LTV) calculations or liquidation engines.
• Admin key compromises granting excessive protocol control. Users must audit the audit: review which firms examined the code, the scope of the review, and whether findings were addressed.

Liquidating undercollateralized NFT loans is inherently difficult due to asset illiquidity. If a borrower defaults, the protocol must sell the NFT to recover funds, which may fail if there are no buyers at the required price. This can result in bad debt for the protocol. Mechanisms to manage this include:

• Dutch auctions to gradually lower the price.
• Staking incentives for liquidators.
• High collateral factors (low LTV ratios) for volatile collections.

Users face dependency on the continued operation and solvency of the NFT-Fi platform. This includes:

• Borrower default risk for lenders in peer-to-peer models.
• Protocol insolvency if bad debt exceeds treasury reserves.
• Rug pulls where fraudulent project creators abandon fractionalized NFTs (e.g., ERC-20 tokens tied to a worthless NFT).
• Censorship risk if a platform can freeze or seize assets based on centralized governance.

Unique risks stem from NFT standards and metadata:

• Metadata Centralization: If the NFT's art/metadata is stored off-chain (e.g., HTTP URL), it can be altered or deleted, destroying the asset's value.
• Standard Exploits: Vulnerabilities in specific implementations of ERC-721 or ERC-1155 can be exploited across all dependent NFTs.
• Airdrop & Reward Sniping: Protocols offering rewards for staking NFTs can be gamed by users who rapidly acquire and stake NFTs just before reward snapshots.

NFT-Fi products may attract regulatory scrutiny. Key areas of concern:

• Securities Laws: Fractionalized NFTs (ERC-20 tokens representing NFT shares) may be classified as securities in some jurisdictions.
• Money Transmission: Lending protocols facilitating fiat off-ramps may require licenses.
• Tax Treatment: The tax implications of NFT lending, borrowing, and derivative trading are often unclear and vary by region, creating compliance complexity for users.

A core NFT-Fi primitive that allows users to use NFTs as collateral for loans. Borrowers gain liquidity without selling their assets, while Lenders earn interest by providing capital. This is typically facilitated through peer-to-peer agreements or peer-to-pool protocols like BendDAO or JPEG'd.

• Peer-to-Peer: Direct negotiation of terms (loan amount, duration, interest).
• Peer-to-Pool: Users borrow from a shared liquidity pool, with loans often overcollateralized and subject to liquidation if the collateral value falls.

The process of dividing ownership of a single NFT into multiple fungible shares or tokens (e.g., ERC-20 tokens). This lowers the barrier to entry for high-value assets and creates instant liquidity.

• Example: A CryptoPunk NFT is locked in a vault, and 10,000 $PUNK tokens are issued, each representing a fractional claim.
• Mechanism: Uses a smart contract (vault) to custody the NFT and manage the minting/burning of fractional tokens.

Derivative contracts that allow traders to speculate on the future price of an NFT collection index without owning the underlying assets. Traders can take long or short positions with leverage.

• Settlement: Cash-settled in a stablecoin based on the index price of a collection (e.g., the BAYC floor price).
• Platform Example: NFTPerp uses a virtual automated market maker (vAMM) model for decentralized trading of these perpetuals.

A model enabling temporary, permissioned use of an NFT without transferring full ownership. This unlocks utility for gaming assets, membership passes, or avatar NFTs.

• Use Case: Renting a Yuga Labs Otherside parcel for a gaming session or leasing a Bored Ape for a social media profile.
• Mechanism: Uses smart contracts with time-locked transfers or delegated authority (via ERC-4907 standard) to grant temporary usage rights.

Financial derivatives that give the holder the right, but not the obligation, to buy (call option) or sell (put option) a specific NFT at a predetermined price before a set expiry. This provides hedging and speculative strategies.

• Hedging: A collector can buy a put option to insure against a decline in their NFT's value.
• Speculation: A trader can buy a call option to gain exposure to potential price appreciation with limited capital at risk.

Tokenized funds that provide diversified exposure to a basket of NFTs, typically tracking an index of top collections. They abstract away individual asset selection for passive investors.

• Mechanism: A fund vault holds underlying NFTs, and fund shares are issued as fungible tokens.
• Example: NFTX vaults create index-like tokens (e.g., PUNK-BASIC) that represent a claim on a pool of assets from a specific collection.

While unlocking liquidity, NFT-Fi introduces distinct risks:

• Liquidation Risk: Volatile NFT prices can trigger rapid collateral liquidations.
• Oracle Risk: Reliance on pricing feeds creates vulnerability to manipulation or stale data.
• Smart Contract Risk: Complex financial logic increases the attack surface for exploits.
• Regulatory Uncertainty: Many NFT-Fi activities may fall under securities or derivatives regulations. Understanding these is critical for protocol designers and users.
