Key Features

Uniswap is a DEX (decentralized exchange), and all users, working with it, retain control over their funds at any given time. Another difference from centralized exchanges is the automated protocol for market creation. It encourages people who trade on the exchange to become liquidity providers (LPs).

Uniswap users pool their money to create a fund (pool), within which all trade transactions are then executed. Each trading pair has its own pool and users can contribute to it. The prices of all assets are determined using a mathematical algorithm.

Such a system allows you to execute transactions instantly, rather than waiting for the opposite order from the buyer / seller to appear. The only condition is that the pool must have enough liquidity to execute the transaction.

Uniswap is completely open source and anyone can grab it and use it to create their own DEX. There are two smart contracts at the heart of it: Factory and Exchange. The first is used to add new tokens to the platform, and the second is used directly for transactions.

Difference between Uniswap v2 and v3

At the moment, the third version of the protocol has already been announced. The release will take place on May 5, 2021 on the Ethereum mainnet, and a little later on Ethereum Optimism. What the new version offers:

  • Concentrated liquidity. Consolidation of individual positions into a common pool, so that liquidity providers can better control the price range to which their capital is focused.
  • Several levels of commissions. LPs will be able to take on one or another level of risk, and based on this, their income will be determined.
  • How will this affect the development of the protocol:
  • The capital efficiency for liquidity providers can be 4,000 times higher than before.
  • The slippage of transactions will become even lower.
  • Liquidity providers will be able to sell one asset after another, adding liquidity at a price above or below market prices.
  • Reduced risk of loss of preferred assets for LPs.
  • Significantly reduced the complexity and cost of integrating Uniswap oracles, eliminating the need to validate historical values.

With all this, it is assumed that transactions after the deployment of the protocol on Optimism will become significantly cheaper.

sharing settings
  • Slippage tolerance (the transaction will be canceled if the value of the asset has changed by more than the specified percentage at the time of its execution).
  • Deadline transaction (automatic cancellation if it was not possible to process the transaction within the specified number of minutes).
  • Interface settings – activating the expert mode, limiting swaps to direct pairs only.

How to make money on Uniswap. UNI token

In exchange for placing their assets, each liquidity provider receives a token, which confirms the fact of its investment in the pool.

For example, if you contributed $ 10,000 to a liquidity pool that contained $ 100,000 in total, you will receive tokens that entitle you to 10% of this pool. This token allows you to receive income in UNI from commissions for all operations in the pool (yours and others), the commission percentage is determined from the percentage of ownership described earlier.

Uniswap charges users a flat fee of 0.30% per trade and automatically sends it to the liquidity pool. As soon as the liquidity provider decides that it wants to withdraw its assets, it receives a portion of the total fees from the reserve relative to its rate in this pool. The LP token, which stores information about the share of income, is then destroyed.

To add liquidity, you need to click the “Add” button.

Then “Add Liquidity”, and select the desired currency pair. Enter the quantity of one asset, the second will be calculated automatically at the market price. Confirm the operation in Metamask.

By doing this, you will receive liquidity tokens and immediately start earning profit from the commissions in this pool. Uniswap already has more than $ 4.19 billion in assets frozen, according to Defipulse.
