NFT Collateral

The Loan-to-Value (LTV) Ratio is the primary risk parameter, expressed as a percentage of the NFT's appraised value that a lender is willing to advance. It is calculated as (Loan Amount / Collateral Value) * 100. A lower LTV (e.g., 30-50%) provides a larger safety buffer for the lender against price volatility. LTVs are dynamically adjusted based on the NFT's collection, rarity, and market liquidity.

A liquidation is the forced sale of NFT collateral triggered when its value falls below a predefined threshold, protecting the lender from loss. Key mechanisms include:

• Liquidation Threshold: The LTV level (e.g., 80%) at which the position becomes eligible for liquidation.
• Liquidation Auctions: Most protocols use a time-bound Dutch auction or fixed-price sale to recover the loan.
• Health Factor: A numeric representation of a position's safety; when it drops below 1, liquidation is triggered.

Accurate, real-time valuation is the foundation of NFT lending. Protocols rely on price oracles to determine collateral value, using methodologies like:

• Floor Price Oracles: Track the lowest listed price for an NFT collection.
• Time-Weighted Average Price (TWAP): Smooths out volatility using historical price data.
• Pricing Committees: Some platforms use manual, community-driven appraisals for ultra-rare assets.

Not all NFTs are equal as collateral. Protocols categorize them into tiers based on risk:

• Blue-Chip Collections: High-floor, liquid collections (e.g., Bored Ape Yacht Club) receive the best LTV terms.
• Established Collections: Proven projects with consistent volume and community.
• Emerging Collections: Newer or less liquid NFTs face stricter terms or may be ineligible. This tiering manages counterparty risk and market risk for lenders.

NFT-backed loans come in two primary structures:

• Peer-to-Pool (P2P): Borrowers take loans from a unified liquidity pool; terms are set algorithmically by the protocol. This is the most common model (e.g., NFTfi, BendDAO).
• Peer-to-Peer (P2P): A borrower and lender negotiate custom terms (amount, duration, interest) directly via an order book (e.g., Blur Lend). Loans can be fixed-term (with a maturity date) or open-ended (until liquidation or repayment).

A critical feature is that the borrower typically retains all utility and social rights to the NFT while it is collateralized. This means they can still:

• Use the NFT as a profile picture (PFP).
• Access token-gated communities and experiences.
• Earn potential airdrops or staking rewards from the underlying project. Ownership is only transferred if the loan is liquidated, making it a non-custodial form of finance.

The primary risk in NFT lending is extreme price volatility. An NFT's value can drop rapidly, triggering a liquidation where the collateral is automatically sold to cover the loan. Unlike stable assets, NFTs often lack deep, continuous markets, making it difficult to execute liquidations at fair prices, potentially leaving borrowers with debt and lenders with losses.

• Example: A Bored Ape used as collateral for a 50 ETH loan could see its floor price drop 40% in a week, leading to a forced sale for far less than the borrowed amount.

NFT lending protocols rely on price oracles to determine collateral value. If an oracle provides stale or manipulated data, it can cause incorrect liquidations or allow undercollateralized loans.

• Wash trading on a marketplace can artificially inflate an NFT's recorded price, tricking the oracle into overvaluing collateral.
• A malicious actor could exploit a flaw in the oracle's pricing mechanism (e.g., relying on a single marketplace's API) to drain the lending pool.

The entire system depends on the security of its smart contracts. Vulnerabilities can lead to catastrophic loss of funds.

• Reentrancy attacks could allow an attacker to drain collateral vaults.
• Logic bugs in the loan issuance, interest accrual, or liquidation engine can be exploited.
• Admin key risk: Many protocols have multi-sig wallets or admin functions that can upgrade contracts or pause operations, representing a centralization risk.

NFTs present unique custody challenges not found with fungible tokens.

• Wrapped NFT (wNFT) Risk: Collateral is often held as a wrapped NFT in a protocol's vault contract. Users must trust the integrity of the wrapping mechanism.
• Rug Pulls & IP Rights: If the underlying NFT project is a scam (rug pull) or has its intellectual property rights revoked, the collateral's value can go to zero.
• Illiquidity: Even a valuable NFT may have no immediate buyers during a market downturn, causing a liquidation cascade where the protocol cannot recover the loan value.

The process of selling collateral to repay a loan is fraught with execution risk.

• Dutch auctions are a common liquidation method, but if no one bids, the lender may be left with an illiquid NFT.
• Slippage can be severe, especially for rare, high-value NFTs, where the forced sale price may be significantly below the last recorded oracle price.
• Liquidation penalties are often high (e.g., 10-15%) to incentivize keepers, but this increases the loss for the borrower.

The decentralized nature of these protocols does not eliminate all traditional financial risks.

• Counterparty Risk: While non-custodial for lenders, there is still risk from the borrower's default and the protocol's inability to recover funds via liquidation.
• Regulatory Uncertainty: NFTs used as financial collateral may attract regulatory scrutiny. A jurisdiction could deem certain NFT lending activities as unlicensed securities lending or money transmission.
• Tax Implications: Liquidations and loan forgiveness can have complex and unforeseen tax consequences for both parties.

A decentralized lending model where individuals negotiate loan terms directly, using an NFT as collateral. This is the foundational mechanism for most NFTfi platforms.

• Key Features: Terms (loan-to-value ratio, duration, interest) are set by the lender, not a protocol.
• Process: A borrower lists their NFT with desired terms; a lender accepts and funds the loan.
• Example: A user posts a Bored Ape for a 30 ETH loan at 10% APR over 90 days.

A capital-efficient model where borrowers take loans from a shared liquidity pool, with the protocol algorithmically setting rates based on supply and demand.

• Key Features: Lenders deposit funds into a pool to earn yield; borrowers draw from it instantly.
• Automation: Interest rates are typically dynamic, adjusting based on pool utilization.
• Platform Example: BendDAO uses this model for blue-chip NFT loans, with real-time health factors and liquidation mechanisms.

The automated process of seizing and selling a collateralized NFT when a loan's health factor falls below a safe threshold (e.g., if the NFT's value drops).

• Trigger: Occurs when the loan's value exceeds the collateral's value minus a safety margin.
• Auction: Liquidated NFTs are often sold via a Dutch or English auction on the platform.
• Risk: A major liquidation event can cause downward price pressure on the NFT collection.

A core risk metric representing the loan amount as a percentage of the collateral's appraised value. A lower LTV indicates a safer, more conservative loan.

• Calculation: (Loan Amount / Collateral Value) * 100.
• Example: A 10 ETH loan against a 50 ETH NFT has a 20% LTV.
• Protocol Setting: P2P lenders set this manually; P2Pool protocols use a maximum LTV as a key parameter.

The critical challenge of determining a fair market price for collateral. Protocols rely on price oracles to provide real-time, tamper-resistant NFT floor prices and collection data.

• Methods: Floor price, time-weighted average price (TWAP), and trait-based pricing models.
• Oracle Providers: Services like Chainlink and UMA supply price feeds that trigger liquidations.
• Risk: Oracle manipulation or stale data can lead to incorrect liquidations.

An advanced DeFi tactic where a user borrows assets with no upfront collateral, executes a series of transactions (like buying, using, and selling an NFT), and repays the loan all within a single blockchain block.

• Requirement: The entire operation must be atomic—it reverts if the loan isn't repaid.
• Use Case: Arbitrage, collateral swapping, or complex refinancing without capital lock-up.
• Platform Example: NFTfi and other platforms have integrated flash loan functionality.
