You heard about a new token launch, but it's not on Binance or OKX?
That's because it might only trade on decentralized exchanges (DEXs). Uniswap is the world's largest DEX, processing billions in daily volume.
This guide teaches you how to trade on Uniswap from scratch.
Prerequisites
Before starting, you need:
| Item | Details |
|---|---|
| MetaMask wallet | Or other Web3 wallets (Rabby, Rainbow) |
| ETH for gas | At least $10-20 in ETH for transaction fees |
| Tokens to swap | ETH, USDC, etc. (already in your wallet) |
Step 1: Connect Your Wallet
- Open app.uniswap.org from your bookmarks (always use bookmarks!)
- Click "Connect" in the top right
- Select your wallet (MetaMask is most common)
- Confirm the connection in MetaMask
Warning
Phishing Warning
Uniswap has countless phishing clones. Only use app.uniswap.org, accessed from bookmarks. Never click from Google search results — fake sites often appear in paid ad positions.
Step 2: Select Tokens
- In "You pay," select the token you're selling (e.g., ETH)
- In "You receive," select the token you're buying
- Enter the amount
Finding the Correct Token
| Method | Reliability |
|---|---|
| Copy contract address from CoinGecko/CoinMarketCap | ✅ Most reliable |
| Search by name in Uniswap, then verify address | ⚠️ Needs verification |
| Click links from community posts | ❌ High risk |
Danger
Fake Token Trap
Anyone can create a token on Uniswap with any name — including identical names to real tokens. The only way to verify is the contract address. Always copy the correct address from trusted sources like CoinGecko!
Step 3: Set Slippage
Slippage is the price deviation range you're willing to accept:
| Slippage | Best For |
|---|---|
| 0.1-0.5% | Major tokens (ETH/USDC, high liquidity pairs) |
| 1-3% | Medium liquidity tokens |
| 5%+ | Low liquidity/new tokens (high risk, MEV target) |
Step 4: Confirm the Swap
- Verify the exchange rate and expected receive amount
- Check "Price Impact" — over 5% means low liquidity
- Click "Swap"
- Confirm in MetaMask — check gas fees are reasonable
- Wait for on-chain confirmation
Gas Fee Savings
| Tip | Savings |
|---|---|
| Switch to Uniswap on Arbitrum/Base | 95%+ gas savings |
| Trade during low-gas periods (UTC 0-6am) | 30-50% savings |
| Avoid trading during market panic | Gas spikes during fear |
Common Issues
| Problem | Cause | Solution |
|---|---|---|
| Transaction keeps failing | Slippage too low | Increase to 1-3% |
| Abnormally high gas | Network congestion | Wait for off-peak or use L2 |
| Token not found | Need manual address input | Copy from CoinGecko |
| Can't sell token | Possible honeypot | Check on honeypot.is first |
Conclusion
Moving from centralized exchanges to Uniswap is like going from online banking to cash — you gain more autonomy but shoulder more responsibility.
Remember three core principles: bookmark access, verify contracts, control slippage. Follow these, and you can safely explore the DEX world.
