Features
Optimistic rollup 
ZK-rollup 
Proof
Uses fraud proofs to prove transaction validity. 
Uses validity (zero-knowledge) proofs to prove transaction validity. 
Capital efficiency
Requires waiting through a 1-week delay (dispute period) before withdrawing funds. 
Users can withdraw funds immediately because validity proofs provide incontrovertible evidence of the authenticity of off-chain transactions. 
Data compression
Publishes full transaction data as calldata to Ethereum Mainnet, which increases rollup costs. 
Doesn't need to publish transaction data on Ethereum because ZK-SNARKs and ZK-STARKs already guarantee the accuracy of the rollup state. 
EVM compatibility
Uses a simulation of the Ethereum Virtual Machine (EVM), which allows it to run arbitrary logic and support smart contracts. 
Doesn't widely support EVM computation, although a few EVM-compatible ZK-rollups have appeared. 
Rollup costs
Reduces costs since it publishes minimal data on Ethereum and doesn't have to post proofs for transactions, except in special circumstances. 
Faces higher overhead from costs involved in generating and verifying proofs for every transaction block. ZK proofs require specialized, expensive hardware to create and have high on-chain verification costs. 
Trust assumptions
Doesn't require a trusted setup. 
Requires a trusted setup to work. 
Liveness requirements
Verifiers are needed to keep tabs on the actual rollup state and the one referenced in the state root to detect fraud. 
Users don't need someone to watch the L2 chain to detect fraud. 
Security properties 
Relies on cryptoeconomic incentives to assure users of rollup security. 
Relies on cryptographic guarantees for security.

Uniswap is an open-source, decentralized crypto exchange platform built on the Ethereum blockchain. It makes use of a model (Automated liquidity protocol) that incentivizes people to become liquidity providers in order to solve the liquidity problem in crypto exchange platforms.

Uniswap currently has over $10.3 billion worth of assets locked in its platform and has also exceeded 1 trillion swaps. In this article, we will be showing you a step-by-step process on how to trade tokens on Uniswap.

1. Download and Install Metamask

There are several wallets compatible with Uniswap, however, we will be making use of metamask in this tutorial.

Go to Metamask, then download and install metamask as a browser extension. Supported browsers include Chrome, FireFox, Brave, Edge, and Opera. For PCs and as an app for mobile phones use Google play for Android or the App Store for iOS.

2. Create an account and note down your secret recovery phrase.

‍Note: Never share your recovery phrase with anyone, losing it means losing access to all your funds.

2. Fund your Metamask wallet

1. Copy your Metamask address, and then click on your account address to copy.

Metamask Chrome Extension - Copy your Address

2. Go to a crypto exchange (Binance, Coinbase).

3. Buy some ETH and send them to your address to withdraw it. 

Note that you can purchase any ERC20 tokens, but we are using ETH because we would need it to pay for gas fees.

3. Connect your Wallet

1. Go to Uniswap, then click on the launch App button, this button directs you to an interface to connect your wallet.

2. Click on the connect button to connect your wallet.

4. Trade on Uniswap

2. Specify the amount of ETH you want to spend, and the amount of tokens you can get automatically shows up. We also get to see the gas fees for the specified amount.

3. Check your settings: This is not compulsory for every transaction, but is necessary if you want to know the details of your transaction. From the settings, we can see the following: 

  • The Slipagge tolerance - When the price of the token changes, your transaction will fail if it exceeds the stipulated percentage.
  • Transaction deadline -  Your transaction shouldn’t exceed the stipulated time.
  • User interface settings - Allows you to access other features in the user interface.

4. Click on the "Swap" button, and confirm the transaction on your Metamask.

Note that the "Swap" button only shows up when you have a sufficient ETH balance to process the transaction. It might take a few minutes to go through but, after it has gone successfully you should be able to see your balance.
