Yield Farming with NFTs and Fractionalized Assets

Detailed Instructions

Begin by clearly defining your strategy's target APY, risk tolerance, and capital allocation. For NFT-based strategies, this involves selecting specific collections based on floor price stability, trading volume, and utility. For fractionalized assets, assess the underlying asset's liquidity and the fractionalization protocol's security.

• Sub-step 1: Set Objectives: Determine if the goal is high yield, capital preservation, or diversification. A common target might be a 15-25% APY with moderate risk.
• Sub-step 2: Select Asset Classes: Choose between NFTfi platforms like BendDAO for NFT collateralized loans or fractionalization protocols like Fractional.art for splitting high-value NFTs.
• Sub-step 3: Define Risk Metrics: Establish maximum drawdown limits (e.g., 20%) and decide on liquidation thresholds for leveraged positions.

Tip: Use tools like Dune Analytics to model historical returns for similar strategies before committing capital.

This step involves building the automated vault logic that handles deposits, strategy execution, and fee collection. The architecture must securely interact with DeFi primitives like Aave for lending and Uniswap V3 for liquidity provision. A critical component is the keeper bot that triggers harvests and rebalances.

• Sub-step 1: Design Vault Contract: Create a contract that accepts ERC-20 tokens (for fractions) and ERC-721 tokens (for NFTs). Implement a deposit() function that mints shares.
• Sub-step 2: Integrate Yield Sources: Write functions to deposit collateral into platforms. For example, to lock an NFT on BendDAO:

solidityCopy
function _depositNFTToBend(address nftAddress, uint256 tokenId) internal {
    IERC721(nft).safeTransferFrom(address(this), address(bendDAO), tokenId);
    bendDAO.deposit(nftAddress, tokenId, address(this));
}

• Sub-step 3: Implement Harvest Logic: Code a harvest() function that claims rewards (e.g., $BEND tokens), sells them for more strategy assets, and reinvests.

Tip: Use OpenZeppelin's Audited Contracts for security and implement a timelock for sensitive administrative functions.

Backtesting is essential to avoid real financial loss. Use platforms like DefiLlama's Yield SDK or custom scripts to simulate the strategy against historical price data. Pay special attention to impermanent loss in liquidity pools and NFT floor price volatility during market downturns.

• Sub-step 1: Gather Historical Data: Pull 6-12 months of price data for target assets (e.g., BAYC floor price from Reservoir API) and yield rates from protocols.
• Sub-step 2: Model Transactions: Simulate the cost of all on-chain actions, including gas fees on Ethereum mainnet (e.g., 50 gwei average) and protocol fees (e.g., 0.3% performance fee).
• Sub-step 3: Run Stress Tests: Test the strategy under extreme conditions, like a 40% drop in NFT prices, to ensure the liquidation engine functions and the vault remains solvent.

Tip: Consider using a forked mainnet environment via Foundry's anvil command (anvil --fork-url https://eth-mainnet.g.alchemy.com/v2/your-key) for highly accurate simulations.

Detailed Instructions

Deploy the audited contracts to the Ethereum mainnet (or an L2 like Arbitrum for lower fees) and open the vault for deposits. Real-time monitoring is critical to track TVL (Total Value Locked), APY fluctuations, and liquidation risks. Use off-chain keepers with services like Gelato Network to automate harvests.

• Sub-step 1: Deploy Contracts: Use a script with Hardhat. Example deployment command:

bashCopy
npx hardhat run scripts/deploy.js --network mainnet

• Sub-step 2: Set Up Monitoring Dashboards: Create a dashboard using The Graph to index vault events and Dune Analytics to track performance publicly. Monitor key addresses like the strategy vault 0x742d35Cc6634C0532925a3b844Bc9e.
• Sub-step 3: Establish an Iteration Cycle: Based on performance data, propose and vote on strategy parameter updates (e.g., adjusting the harvest threshold from 1 ETH to 0.5 ETH) via the vault's governance mechanism.

Tip: Implement multi-sig wallet controls (e.g., Gnosis Safe) for all administrative functions to enhance security and decentralization.

Detailed Instructions

Begin by selecting a high-value, blue-chip NFT from a supported collection like Bored Ape Yacht Club (BAYC) or CryptoPunks. The NFT's floor price and rarity will determine your borrowing power. You'll need to connect your Web3 wallet (e.g., MetaMask) to a platform like NFTfi or Arcade.xyz. Approve the platform's smart contract to access your NFT, then deposit it into a specific lending vault. This action locks your NFT and mints a wrapped NFT (wNFT) or a vault receipt token representing your collateralized position. Always verify the contract address (e.g., 0x4b...a1f3 for BAYC) and review the loan terms, including the Loan-to-Value (LTV) ratio and liquidation threshold, before confirming.

• Sub-step 1: Connect wallet to the chosen lending dApp and navigate to the 'Deposit Collateral' section.
• Sub-step 2: Select your NFT from the wallet, review the estimated valuation provided by the platform's oracle.
• Sub-step 3: Sign the transaction to approve and deposit. The gas fee for this on Ethereum Mainnet could be ~0.05 ETH.

Tip: Use a platform with a reputable price oracle to ensure fair valuation and avoid premature liquidation.

Detailed Instructions

Once your NFT is locked, you can borrow a stablecoin like DAI or USDC. The amount is a percentage of the NFT's appraised value, typically 30-50% LTV. For a BAYC valued at 100 ETH, you might borrow 15,000 DAI. This creates a debt position represented by an ERC-721 debt token. To enable broader investment, you can fractionalize this debt position using a protocol like Fractional.art or NFTX. This process locks the debt token into a new smart contract that mints a set number of ERC-20 tokens (e.g., 10,000 BAYC-DEBT-1 tokens), each representing fractional ownership of the future loan repayment and yield.

• Sub-step 1: On the lending platform, specify the loan amount (e.g., 15,000 DAI) and duration (e.g., 90 days). Sign the loan agreement transaction.
• Sub-step 2: Navigate to a fractionalization platform. Deposit the received debt NFT into a new vault using a function like createVault(ERC-721 debtTokenAddress, 10000, "BAYC-DEBT-1", "BDEBT").
• Sub-step 3: The vault mints the ERC-20 fractional tokens to your wallet. Distribute a portion to potential investors.

Tip: Set a conservative LTV to create a safety buffer against NFT price volatility and liquidation.

Detailed Instructions

With the borrowed stablecoins in hand, you now deploy them into high-yield liquidity pools (LPs). A common strategy is to provide liquidity to a stablecoin pair on a Decentralized Exchange (DEX) like Curve Finance or Uniswap V3. For example, you could supply 15,000 DAI to the Curve 3pool (DAI/USDC/USDT). This gives you LP tokens representing your share of the pool. To amplify returns, you can then stake these LP tokens in a yield farming contract, often called a gauge or farm, to earn additional reward tokens (e.g., CRV or BAL). The smart contract interaction typically involves two approvals and two deposits.

• Sub-step 1: Approve the DEX router (e.g., 0xd9e1cE17f2641f24aE83637ab66a2cca9C378B9F for SushiSwap) to spend your DAI.
• Sub-step 2: Add liquidity, receiving LP tokens. A sample call: router.addLiquidity(tokenA, tokenB, amountADesired, amountBDesired, ...).
• Sub-step 3: Approve and stake the LP tokens in the farm contract: farm.deposit(lpTokenAmount).

Tip: Use yield aggregators like Yearn Finance to automate the process of finding and compounding the highest yields across protocols.

Detailed Instructions

Active management is crucial. You must monitor your collateral health factor on the lending platform to avoid liquidation if the NFT value drops. Regularly harvest farming rewards using the farm contract's getReward() function. To maximize returns, compound these rewards by selling a portion for more LP tokens and re-staking. The exit strategy involves reversing the process: unstake LP tokens, remove liquidity to get stablecoins back, and repay the loan plus interest to reclaim your original NFT. Finally, dissolve the fractionalized vault to allow holders to redeem their share of the repaid capital.

• Sub-step 1: Weekly, call farm.getReward() to claim CRV tokens. Swap 50% to DAI and re-add liquidity.
• Sub-step 2: Continuously check your loan's health at the lender. If the ratio nears liquidation, add collateral or repay partially.
• Sub-step 3: To exit, call farm.withdraw(lpTokenAmount), then router.removeLiquidity(...) to get DAI back. Repay the loan on the lending platform using repayLoan(loanId).
• Sub-step 4: On the fractional vault, call endVault() to allow ERC-20 holders to redeem their DAI share, burning their tokens.

Tip: Automate monitoring and harvesting using a tool like Gelato Network to create a recurring task for reward collection.
