Uniswap Wallet Connection Problems & Fixes

If your wallet won't connect to Uniswap:
- Make sure your wallet extension is installed and unlocked.
- Refresh the page and try connecting again.
- Use a supported browser (Chrome or Brave work best with MetaMask).
- Disable conflicting extensions (other wallets, ad-blockers, VPNs).
- Clear cache and cookies, then reconnect.
Wrong Network / ChainNetwork
Uniswap needs your wallet to be on a supported network.
- Open the network selector in the top-right of Uniswap.
- Pick Ethereum, Base, Arbitrum, Optimism, Polygon or another supported chain.
- Approve the network switch request in your wallet.
MetaMask Not DetectedMetaMask
- Confirm the MetaMask extension is enabled in your browser.
- Click the MetaMask icon and unlock it with your password.
- Reload Uniswap and try connecting again.
- In Brave, disable Shields for app.uniswap.org.
Transaction Pending / StuckTransactions
- In MetaMask: Settings → Advanced → Clear activity tab data to reset pending transactions.
- Speed up the transaction by increasing the gas price.
- Raise slippage tolerance for low-liquidity tokens.
- Wait for network congestion to clear and check the block explorer.
High Slippage or Price ImpactSwaps
- Lower your swap amount to reduce price impact on thin pools.
- Set slippage to 0.1–0.5% for stable pairs, higher for volatile tokens.
- Try a different network or route — UniswapX often finds better prices.
Stay Safe on Uniswap
Verify the URL
Always check you're on app.uniswap.org. Scammers create fake sites with similar URLs — bookmark the official app.
Never Share Your Recovery Phrase
Uniswap will never ask for your recovery phrase or private key. Anyone who does is a scammer.
Keep ETH for Gas
Keep a small amount of the network's native token (ETH, etc.) to pay gas fees for swaps and approvals.
Verify Token Contracts
When swapping new tokens, verify the contract address on Etherscan — don't rely on the token name alone.

About Uniswap
Uniswap is a decentralized exchange protocol launched in November 2018 by Hayden Adams. It uses an automated market maker (AMM) model, letting anyone swap ERC-20 tokens directly from their wallet without a centralized intermediary.
The protocol has grown into a multichain ecosystem spanning Ethereum and 12+ networks. Products include the Uniswap web app, the self-custody Uniswap Wallet, UniswapX aggregation, and Unichain — a Layer 2 built for DeFi.
The UNI token powers Uniswap Governance, letting the community steer the protocol. Uniswap v4 introduces hooks and a singleton architecture for customizable pools and lower gas costs. Official documentation: docs.uniswap.org.
