PancakeSwap Guide on BNB Chain

PancakeSwap is the leading decentralized exchange on BNB Chain, but how do you start using it without making common mistakes that could cost you funds?

TL;DR

• You'll learn to connect a wallet, swap tokens, add liquidity, and join yield farming.
• Avoid risks like impermanent loss, scams, and failed transactions.

Context

PancakeSwap is a DEX (decentralized exchange) based on an AMM (Automated Market Maker) model. Users trade tokens against liquidity pools instead of direct orders. It's relevant for low fees, high volume, and features like yield farming and lottery.
Risks: Impermanent loss when providing liquidity, price volatility, and potential smart contract bugs, despite audits.

Prerequisites

• A wallet compatible with BNB Chain (MetaMask, Trust Wallet, or WalletConnect).
• Some BNB for gas fees.
• BEP-20 tokens to swap (you can transfer from Binance).

Step by step: How to start using PancakeSwap

1. Go to the official site: pancakeswap.finance.
2. Click "Connect wallet" in the top right corner.
3. Select your wallet and approve the connection. Switch to BNB Chain network if needed. 💡 Tip: Add BNB Chain manually in MetaMask if it doesn't appear (RPC: https://bsc-dataseed.binance.org/).
4. For a basic swap: Select "Trade" > "Swap".
5. Choose the from and to tokens, enter the amount.
6. Adjust slippage tolerance (start with 0.5-1%).
7. Confirm the transaction in your wallet. ⚠️ Security: Always check the destination token contract address.
8. To add liquidity: Go to "Liquidity" > "Add".
9. Select the token pair and equal value amounts.
10. Approve tokens and confirm. 💡 Tip: Use stable pairs to reduce impermanent loss risk.

Optional (advanced): Join Farms to yield farm by staking your LP tokens and earn CAKE.

Security checklist

⚠️ Use only pancakeswap.finance (bookmark it). ⚠️ Never share your seed phrase or private key. ⚠️ Revoke old approvals using tools like bscscan.com/tokenapprovalchecker. ⚠️ Start with small amounts. ⚠️ Check audits and updates on docs.pancakeswap.finance. ⚠️ Use a hardware wallet for large amounts. ⚠️ Monitor transactions on BscScan. ⚠️ Avoid unofficial social media links.

Common errors and how to avoid them

• High slippage → Failed transaction: Slightly increase tolerance, but not too much to avoid front-running.
• Impermanent loss → Losses on withdrawal: Choose correlated pairs (like stablecoins); calculate externally beforehand.
• Connecting to fake site → Fund theft: Always type the URL manually or use bookmark.
• Approving scam token → Wallet drain: Research new tokens and approve only what's needed.

Practical examples

• Simple swap: Exchange 100 USDT for BNB. Enter 100 USDT, check estimated output (e.g., 0.15 BNB), confirm. Gas ~0.001 BNB.
• Add liquidity: 500 USDT + equivalent BNB. Receive LP tokens and earn 0.17% of pool fees (part of total 0.25%).

Quick comparisons

• Advantages vs. Uniswap: Much lower gas fees on BNB Chain, faster transactions.
• Disadvantages: Fewer tokens than on Ethereum, risk concentrated on one chain.
