Which network should I use for Uniswap vs PancakeSwap?

Uniswap runs primarily on Ethereum (and other supported chains), so use Ethereum Mainnet for ERC-20 tokens. PancakeSwap runs on BNB Smart Chain (BSC), so use BSC for BEP-20 tokens.

Why do I need ETH or BNB?

You pay gas fees in the native token of the network: ETH on Ethereum and BNB on BSC.

What is token approval?

Before a DEX can spend a token from your wallet, you must approve a smart contract allowance once per token. This is separate from the swap.

What slippage should I use?

Start low (0.3%–0.5%) for liquid pairs. Increase gradually (1%–3% or more) for volatile or illiquid pairs. Higher slippage increases execution risk; only raise if necessary.

My swap keeps failing. What can I do?

Check network, raise gas slightly, increase slippage a bit, ensure sufficient balance for gas, and verify the token contract is correct.

Before You Begin

Install MetaMask (desktop extension or mobile app) and back up your Secret Recovery Phrase safely.
Have a small balance of ETH (for Ethereum) or BNB (for BSC) to pay network gas fees.
Always verify you’re on the official site: app.uniswap.org or pancakeswap.finance.

Never share your seed phrase or private keys. Bookmark official URLs to avoid phishing.

Path A — Connect MetaMask to Uniswap (Ethereum)

Tip: For volatile pairs, increase slippage gradually (e.g., 1%–3%), but understand price impact and MEV risk.

Path B — Connect MetaMask to PancakeSwap (BSC)

In MetaMask, switch network to BNB Smart Chain (add it if needed).
Open pancakeswap.finance and click Connect Wallet → choose MetaMask.
Approve the connection in the MetaMask pop-up.
Select tokens (e.g., From BNB → To CAKE/USDT). Approve token if prompted (first use).
