A Complete Guide to the 1inch Protocol [2021]

Decentralized exchanges are crypto exchanges that do not need to be governed by a third party. Anyone can trade on DEX, with only the need to link their wallets. Uniswap, SushiSwap, and PancakeSwap are a few examples. However, these exchanges sell cryptocurrencies at slightly varying prices. As a result, Ethereum may sell for different prices on different DEXes; each platform charges a different fee. So to get the best pricing from all DEXes, we need 1inch. In this article, we will get a complete understanding of 1inch.

What is 1inch?

1inch is a DEX aggregator that connects many DEXes into a single platform, allowing users to locate the most economical exchanging routes across all platforms.

Why do we need a DEX aggregator?

  • To discover the best price for a swap, a user must look at every exchange.
  • These DEX aggregators reduce the need for manual inspection, providing efficiency to DEX switching.

Working of DEX Aggregator:

DEX aggregators operate by getting liquidity from many DExs, allowing them to provide customers with better token exchange rates than they could obtain on anyone DEX in the shortest amount of time.

How Does 1inch Work?

In this section, we will understand how to 1inch works.

Step 1: Beginning

Suppose we want to purchase some crypto X on a DEX using Ethereum. Then, we have to look at other DEXes; we will see that the rates and fees vary on different DEXes.

Step 2: Algorithm

1inch makes this easy. 1inch’s algorithm determines the cheapest way from all of the available exchanges and liquidity protocols.

Step 3: Conclusion

Now we can purchase the Crypto X from the best deal from a 1inch interface.

What is the difference b/w Simple Mode and Classic Mode?

Simple Mode

  • It allows customers to swap crypto assets in a more user-friendly and simplified interface.
  • It provides three swapping options;
  1. 1inch router: It will route our transaction in the most efficient way, offering the best swap rate.
  2. Direct Swap: Our deal will be routed straight via the Dex with the highest liquidity. It is not necessarily the most affordable.
  3. OTC (Over the counter): It is the best choice for transferring larger amounts. Our transaction will be routed off-chain through registered Private Market Makers.
  • It makes use of Permit 712 Signed token approvals, which eliminates the need to submit authorization for specific tokens.
  • Limit orders are not accessible in Simple Mode. Choosing the Limits tab will return us to Classic Mode.

Classic Mode

  • It includes live charts, limit orders, flashbot transactions, and some other features.

Connect The Wallet

Ethereum address will be shown at the top of the page after the wallet has been linked. We can always check our transaction history, copy the address, or disconnect the wallet by clicking on it.

Step 5: Selecting token

Select the token we wish to swap from the drop-down menu and enter the amount in the you pay area. Next, select the token we want to get in the you receive area.

1inch v2 upgrades

  • On November 5, 2020, the 1inch team launched Version 2 of 1inch.
  • Features:
  1. Pathfinder: It is an API containing a routing algorithm that identifies the best potential pathways for a token exchange in the quickest possible time. This algorithm utilizes different market depths inside the same protocol.
  2. Speed: Comparison quote response time was cut from 6 seconds to 0.4 seconds; Page load time was cut from 5 seconds to 1 second; API quote response time was cut from 5 seconds to 0.4 seconds.
  3. UI: When developing the new user interface, the team considered user feedback and sought to make the UI as intuitive and user-friendly as possible.
  4. Versatility: Uniswap V1, Uniswap V2, WETH, Balancer, Curve, Chai, SushiSwap, Kyber, Oasis, Mooniswap, Compound, Aave, yEarn, Bancor, PMM, Cream Swap, Swerve, BlackholeSwap, Value Liquid, DODO, Shell are all supported by 1inch v2.
  5. Collateral: Users may now pack, unpack, and move collateral tokens from Aave and Compound lending protocols.
  6. Swap Overhead Optimizations: For direct swaps, such as Uniswap, V2 decreases aggregation overhead gas costs to almost nil.
  7. Partial and Dynamic Fill Mechanism: When a user swaps on 1inch utilizing split or other routes, 1inch ensures that the swap is completed at the rate that the user was given in the UI. Suppose the rate on one of the protocols changes, a portion of the route may be quickly cancelled. Instead of a failed transaction, the unswapped coins of the user are returned to their wallet. The dynamic component allows sections of the swap to move to another protocol in the split or route quickly. A swap, for example, is divided among Uniswap, SushiSwap, and Balancer. If the Uniswap swap fails, the full swap will be transferred to Sushiswap and Balancer.

1inch v3 upgrades

  • In March 2021, the 1inch team launched Version 3 of 1inch.
  • Features:
  • Transaction Fees: The potential to significantly cut gas prices due to assembly code optimization.
