How to Trade on Uniswap and Decentralized Exchanges (DEXs) Safely
A step-by-step tutorial on connecting non-custodial wallets, configuring slippage tolerance, routing trades, and avoiding honeypot token contracts.
Step-by-Step Practical Instructions
3 Action StepsVerify Official DEX URL & Connect Wallet
Ensure you are on the verified official domain (e.g., app.uniswap.org). Connect your wallet and select the correct network (Ethereum, Arbitrum, Base).
Paste Official Contract Address for Long-Tail Tokens
Scammers frequently create fake duplicate tokens with identical ticker names. Always copy the official verified contract address from CoinGecko or CoinMarketCap.
Set Appropriate Slippage Tolerance (0.5% - 1%)
High slippage tolerances (e.g., >3%) expose your trade to toxic MEV sandwich attacks that extract profit by raising your execution price.
