Uniswap, a leading decentralized exchange (DEX), has revolutionized cryptocurrency trading by facilitating peer-to-peer (P2P) token swaps without the need for intermediaries. But navigating DeFi, especially across different blockchain networks, can seem daunting. This blog will guide you through using Uniswap on the Optimism (OP) chain, a popular Layer 2 scaling solution for Ethereum, with the help of Blockscout's DAppscout functionality.

Why Use Uniswap on Optimism?

The Ethereum blockchain, where Uniswap was initially deployed, often suffers from high transaction fees and congestion. Optimism addresses this by offering faster transaction speeds and significantly lower fees, making it an attractive option for cost-effective DeFi transactions.

Prerequisites:

Before diving in, ensure you have the following:

• MetaMask Wallet: A popular crypto wallet that supports the Optimism chain. You'll need to configure MetaMask to connect to the OP network. Refer to MetaMask's documentation for setup guidance.

• Optimism (OP) tokens: You'll need some OP tokens in your wallet to cover gas fees on the Optimism network.

6. Set Swap Amount: Enter the amount of the token you're giving up in exchange for the other token. Uniswap will automatically calculate the estimated amount you'll receive based on the current liquidity pool rates.

7. Review and Approve: Double-check the swap details, including the exchange rate and gas fees. Once satisfied, click on "Approve" to initiate the swap.

8. Confirm Transaction: MetaMask will prompt you to confirm the transaction details and gas fees. Review these details carefully before confirming.

Important Note: Transaction speeds and fees can vary depending on network congestion. Consider adjusting gas fees (if possible) to influence transaction speed.

9. Track the Swap: Once confirmed, you can monitor the transaction progress through MetaMask or Blockscout's transaction explorer. Upon successful completion, the swapped tokens will be reflected in your MetaMask wallet.
