Begin by navigating to defillama.com. The homepage presents a wealth of data. The core navigation is the 'Protocols' tab, which lists hundreds of DeFi applications across various blockchains. Use the filters at the top to sort by Total Value Locked (TVL), chain (e.g., Ethereum, Arbitrum, Solana), or category (e.g., DEXes, Lending, Yield).

• Sub-step 1: Filter by Chain: Click 'Chains' and select 'Arbitrum' to see only protocols deployed on that network, like GMX or Camelot.
• Sub-step 2: Analyze a Protocol: Click on a protocol name, such as Aave. You'll be taken to its dedicated page showing detailed metrics like TVL history, token price, and market share.
• Sub-step 3: Compare Protocols: Use the 'Compare' feature to select multiple protocols (e.g., Uniswap, PancakeSwap, Curve) and visualize their TVL trends side-by-side on a chart.

Tip: Bookmark the 'Yields' section under Protocols to find the highest real-yield farming opportunities across chains, filtered by safety score.

DeFi Llama's 'Portfolio' tracker is a powerful tool for unifying your assets. Click the 'Portfolio' tab and connect your wallet using WalletConnect or a browser extension. The dashboard will automatically scan supported chains for your address, aggregating tokens, NFTs, and debt positions.

• Sub-step 1: Connect Wallet: Click 'Connect Wallet' and select MetaMask. In the pop-up, choose the account (e.g., 0x742d35Cc6634C0532925a3b844Bc9e...) and connect.
• Sub-step 2: Review Asset Breakdown: The main view categorizes your holdings by asset type (Tokens, NFTs, Debt) and chain. You can see the USD value of your ETH on Ethereum and your USDC on Polygon in one place.
• Sub-step 3: Inspect Token Details: Click on a specific token entry, like Wrapped Ethereum (WETH), to see its current price, the amount you hold, and its allocation across different protocols (e.g., deposited in Aave, staked in Lido).

Tip: For accurate stablecoin valuation, the portfolio uses Chainlink oracles for pricing. Verify that all your active chains (like Optimism or Avalanche) are toggled on in the chain filter.

Security is paramount in DeFi. On any protocol's page, scroll to the 'Security' section. Here, you'll find the 'Audits' list, showing which firms (like Trail of Bits or Quantstamp) have reviewed the code and when. More importantly, check the 'Category' badge (e.g., 'Lending', 'Dexes') and the 'Chain' verification.

• Sub-step 1: Check Audit History: For a protocol like Compound, review its audit reports. A lack of recent audits for a major update can be a red flag.
• Sub-step 2: Review Treasury and Admin Controls: Look for information on multi-signature wallets or timelock contracts controlling the protocol's treasury. For example, a responsible admin address might be 0xbb... governed by a 5-of-9 multisig.
• Sub-step 3: Monitor Hack History: DeFi Llama often tags protocols that have experienced major exploits. Always check for this warning label before interacting.

Tip: Cross-reference the 'Team Tokens' section to see if a large percentage of the supply is held by founders and its vesting schedule, which impacts tokenomics and sell pressure.

For developers and advanced users, DeFi Llama offers a powerful API. You can fetch real-time and historical data programmatically. Visit the 'API' documentation linked in the site footer. Common endpoints include fetching TVL for a specific chain or protocol history.

• Sub-step 1: Fetch Current TVL: Use a simple curl command to get the total TVL on Arbitrum. curl -X 'GET' 'https://api.llama.fi/v2/chains' -H 'accept: application/json'. Parse the JSON response for Arbitrum's tvl value.
• Sub-step 2: Get Historical Protocol Data: To chart Uniswap's TVL over time, you might call: curl 'https://api.llama.fi/protocol/uniswap'. The response includes a tvl array with date and totalLiquidityUSD pairs.
• Sub-step 3: Access Yields Data: Query the yields endpoint to find the best stablecoin pools: curl 'https://yields.llama.fi/pools'. Filter the results for stablecoin: true and a high apy field.

Tip: For on-chain verification, you can use the 'Contracts' tab on a protocol's page to get verified contract addresses (e.g., Aave's LendingPool address on Ethereum: 0x7d2768dE...) to interact with directly via Etherscan.

Detailed Instructions

Begin by navigating to the official Zapper.fi website. On the homepage, locate and click the "Connect Wallet" button, typically found in the top-right corner. A modal will appear presenting a list of supported wallets like MetaMask, Coinbase Wallet, or WalletConnect. Select your preferred wallet and follow its specific prompts to authorize the connection. This process involves signing a cryptographic message to prove ownership without exposing your private keys. Ensure you are on the correct site to avoid phishing scams.

• Sub-step 1: Open your browser wallet extension (e.g., MetaMask) and ensure you are on the desired network, such as Ethereum Mainnet or Polygon.
• Sub-step 2: In the Zapper connection modal, select your wallet. You may need to approve the connection request in your wallet pop-up.
• Sub-step 3: Verify the connection is successful by checking if your wallet's truncated address (e.g., 0x1a2b...c3d4) is now displayed in Zapper's header.

Tip: For enhanced security, consider using a hardware wallet like Ledger or Trezor in conjunction with MetaMask for signing transactions.

Once connected, you will be directed to your main Portfolio Dashboard. This is a comprehensive overview showing your Total Net Worth, which aggregates the value of your assets across all connected wallets and supported blockchains. Key sections include Assets (tokens), Liabilities (debts from loans), and Investments (staked or pooled funds). Use the chain filter (e.g., Ethereum, Arbitrum, Optimism) to view holdings on specific networks. Click on any asset to see its performance chart, current price, and where it is deployed (e.g., in a Uniswap LP pool or Aave lending market).

• Sub-step 1: Review the "Assets" tab to see a breakdown of your tokens like ETH, USDC, or various DeFi governance tokens.
• Sub-step 2: Examine the "Investments" tab to monitor positions in liquidity pools, yield farms, or vaults, noting metrics like APY and impermanent loss.
• Sub-step 3: Check the "History" tab to audit all your recent transactions and interactions across integrated protocols for better tracking.

Tip: Utilize the "Earn" section to discover new yield opportunities based on your existing portfolio composition and risk tolerance.

Detailed Instructions

To swap tokens, click on the "Swap" tab in the main navigation. Here, you can exchange one token for another directly within Zapper, which aggregates rates from multiple DEX aggregators like 1inch and 0x to find you the best price. Select the input token (e.g., USDC) and the desired output token (e.g., WETH). Enter an amount, and the interface will display a quote showing the expected output, price impact, and network fee. For cross-chain swaps, use the "Bridge" feature. Select the source chain, destination chain, and tokens to move.

• Sub-step 1: In the Swap interface, input 100 for USDC and select WETH as the output. Review the quoted exchange rate.
• Sub-step 2: Adjust slippage tolerance (e.g., set to 1%) in the settings if dealing with volatile assets to prevent failed transactions.
• Sub-step 3: Click "Swap" and confirm the transaction in your connected wallet, paying close attention to the gas fee estimate in ETH or MATIC.

codeCopy
// Example: A typical transaction object your wallet might sign for a swap
{
  to: '0xDEF1CA1FB7FB...', // Zapper's router contract
  data: '0x...', // Encoded swap call
  value: '0', // Value in native token if swapping ETH
  gasLimit: '250000'
}

Tip: Always verify the recipient address in your wallet confirmation is a known Zapper contract, such as 0xDEF1CA1FB7FB..., to avoid scams.

Detailed Instructions

Navigate to the "Invest" or "Earn" section to browse available opportunities. You can filter by protocol (e.g., Curve, Balancer), asset type, or chain. Selecting a pool, like a USDC/DAI stablecoin pool on Curve, will show details including the current Annual Percentage Yield (APY), total value locked (TVL), and your potential share. Zapper often simplifies the process by allowing single-asset deposits, handling the pairing and provisioning of liquidity for you. To invest, click "Deposit", choose the input token and amount, and review the transaction details.

• Sub-step 1: Choose a vault like Yearn Finance's yvUSDC. Examine the strategy description, APY (e.g., 4.2%), and associated risks.
• Sub-step 2: Enter the deposit amount (e.g., 500 USDC). The interface will show you the estimated receipt of vault tokens (e.g., yvUSDC).
• Sub-step 3: Approve the token spending limit for the vault contract first, then confirm the deposit transaction in your wallet.

codeCopy
// First, a typical token approval transaction
{
  to: '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48', // USDC token address
  data: '0x095ea7b30000000000000000000000007f5c...ffff0000000000000000000000000000000000000000000000...', // Approve spender
}

Tip: Monitor your position health and harvestable rewards regularly from your Portfolio dashboard. Consider the risks of smart contract vulnerabilities and impermanent loss before depositing.

Detailed Instructions

Under the "Portfolio" section, navigate to the "Liabilities" tab. Here, you will see an overview of any outstanding loans you have across money markets. This includes details like the collateral asset (e.g., stETH), the borrowed asset (e.g., USDC), your collateralization ratio, and health factor. A health factor below 1.0 risks liquidation. You can manage these positions directly in Zapper. To add collateral, select the position and click "Manage", then choose to deposit more assets. To repay debt, you can supply the borrowed asset from your wallet.

• Sub-step 1: Identify a position with a declining health factor, say 1.15. To avoid liquidation, you might decide to add 0.5 ETH as additional collateral.
• Sub-step 2: In the management interface, select "Add Collateral", input the amount, and confirm the transaction, which will send ETH to the lending protocol's contract.
• Sub-step 3: To repay part of a 500 USDC debt, select "Repay", specify an amount like 100 USDC, and approve the transaction after checking the updated health factor projection.

Tip: Use Zapper's simulation features to see how price changes in your collateral affect your health factor. Always maintain a safe buffer above the liquidation threshold.
