SushiSwap (SUSHI): Bridging DeFi and Crypto Exchange for Beginners

As the world of finance keeps evolving, we're seeing a new trend called 'decentralized finance' or DeFi. It's a way to handle money and investments over the internet, without traditional banks. If you're interested in trading digital currencies like Bitcoin, there are many online platforms you can use, called decentralized exchanges (DEXs). These platforms are available on various digital networks and offer a lot of choices, which might seem a bit confusing at first.

This guide is about one such platform named SushiSwap. It's a popular choice that's been around since 2020 and works specifically with the Ethereum network, a major player in the digital currency world. SushiSwap lets users trade a wide variety of digital tokens. We'll walk you through the basics of how to start using SushiSwap, making it easy to understand even if you're new to this. By the end of this guide, you'll have a clear idea of how to use SushiSwap for trading in the exciting world of digital currencies.

What is SushiSwap?

SushiSwap, an innovative decentralized exchange (DEX) on the Ethereum blockchain, was founded by the pseudonymous developers Chef Nomi and 0xMaki. Initially, it started as a fork of Uniswap, but quickly distinguished itself by offering unique features like liquidity mining and its own governance token, SUSHI.

Like its counterparts Uniswap and Balancer, SushiSwap operates through a series of liquidity pools. Users lock their assets into smart contracts, creating pools from which traders buy and sell various cryptocurrencies. This model aligns with the growing trend in decentralized finance (DeFi), allowing users to trade without a central authority. In SushiSwap’s ecosystem, the SUSHI token not only offers voting power for platform decisions but also grants a share in trading fees and staking rewards.

SushiSwap's early days were marked by controversy and rapid developments. The platform initially encouraged users to stake Uniswap LP tokens to earn SUSHI, leading to what was known as a 'vampire attack'. This strategy temporarily boosted liquidity as users moved their assets from Uniswap to SushiSwap. However, the platform faced a significant setback when Chef Nomi withdrew a substantial amount of funds, leading to a sharp drop in SUSHI's price. This action prompted Chef Nomi to hand over control to Sam Bankman-Fried, the CEO of FTX, who successfully oversaw the migration of liquidity back to SushiSwap.

Despite these early challenges, SushiSwap has emerged as a key player in the DeFi space. It has expanded its offerings beyond simple token swaps to include plans for lending, futures, options, and broader capital market services. The platform's integration with Yearn.finance, announced by Andre Cronje, further cemented its position in the market, sharing development resources while maintaining separate tokens and governance systems.

SushiSwap's journey from a Uniswap fork to a diversified DeFi institution highlights its resilience and adaptability in the ever-evolving landscape of decentralized finance.

How does SushiSwap work?

SushiSwap, a prominent decentralized trading platform, operates using an Automated Market Maker (AMM) model, a significant shift from traditional exchange systems. This innovative approach eliminates the need for an order book and intermediary, allowing peer-to-peer trading directly through liquidity pools. These pools consist of funds from various tokens deposited by users, with smart contracts facilitating liquidity for trades.

A core function of SushiSwap is to replicate the services of a traditional exchange, enabling the buying and selling of diverse crypto assets. Rather than relying on a central authority, SushiSwap utilizes smart contracts to manage the tokens traded on its platform. Users contribute to these pools by locking in their crypto assets, which traders can then access. Those who trade against these locked assets incur a fee that is proportionally distributed among all liquidity providers based on their contribution.

In addition to this fundamental trading mechanism, SushiSwap has expanded its offerings. It now includes features like yield farming, staking, and options for lending and borrowing, all integrated within the same platform. The protocol's expansion into various DeFi tools has transformed it from a platform catering primarily to traders to a more diverse and inclusive financial ecosystem.

Liquidity providers play a crucial role in this ecosystem. By connecting their Ethereum wallet to SushiSwap's farming protocol and locking two assets into a smart contract, they contribute to the platform's liquidity pools. In return, these providers are rewarded with protocol fees and a share of the SUSHI tokens minted daily. Additionally, providers have the flexibility to reclaim their funds along with the cryptocurrency earned from farming.

SushiSwap’s evolution also includes the introduction of cross-chain swaps through the SushiXSwap, powered by the Stargate protocol, facilitating asset swaps across different chains. Moreover, the Furo platform has been developed under SushiSwap's umbrella, streamlining streaming payments and controlling token vesting, particularly beneficial for DAOs and their contributors.

This cohesive structure of SushiSwap exemplifies a forward-thinking approach in decentralized finance, offering a comprehensive suite of services from basic token swaps to sophisticated financial instruments.

How is the SUSHI token used?

SUSHI, initially an Ethereum-based ERC-20 token, plays a pivotal role in the governance of the Sushi ecosystem. It serves as a key incentive for liquidity providers on the SushiSwap Decentralized Exchange (DEX). Beyond governance, SUSHI holders can stake their tokens on the platform to receive xSUSHI, which entitles them to a share of the trading fees, a benefit extended even to those not actively providing liquidity.

In a significant development in December 2022, Sushi Head Chef Jared Grey put forward a proposal to revamp SUSHI's tokenomics. This redesign included introducing time locks for xSUSHI staking, establishing a perpetual token emission rate of 1.5-3%, and implementing a system for burning variable percentages of swapping fees. These changes aim to enhance the token's utility and economic stability.

The SUSHI token has a capped supply of 250 million, with its release into the market commencing in 2020. The distribution was structured to be completed by November 2023, with a graduated release schedule. Notably, 10% of the SUSHI tokens generated in each block are allocated to a development fund, ensuring sustained support for the SushiSwap ecosystem.

SushiSwap, initially based on Uniswap's AMM model, has significantly evolved over the years. It now supports the swapping of digital assets across a variety of blockchains and layer 2 solutions, including the ability to facilitate cross-chain swaps. This expansion reflects SushiSwap's commitment to interoperability and user convenience.

Furthermore, the SUSHI token's functionality encompasses more than just governance. It is instrumental in incentivizing user participation and rewarding platform engagement, creating a dynamic and user-centric decentralized finance environment. SushiSwap's continuous development and adaptation of its tokenomics and features exemplify its dedication to remaining at the forefront of the DeFi sector.

Lend and borrow crypto with Kashi

SushiSwap has recently broadened its DeFi offerings by introducing a new feature for crypto lending and borrowing named Kashi. This platform enables users to borrow cryptocurrencies, requiring them to deposit a specific amount of collateral. The interest charged on these loans is based on a variable annual percentage rate (APR), which adjusts in response to market conditions.

For users interested in lending their assets, Kashi provides an opportunity to earn through a variable reward APR. By depositing their cryptocurrencies into Kashi, lenders can generate returns, which are essentially interest payments made by borrowers. This feature adds a new dimension to SushiSwap’s ecosystem, allowing users to engage in passive income generation through lending.

It's important to note that while the rewards from DeFi lending may sometimes be colloquially referred to as 'staking rewards', they are fundamentally different from the rewards earned through staking in a validator node. In the case of DeFi lending on platforms like Kashi, the rewards are generated from the interest paid by borrowers, not from network validation activities.

However, users should be aware that DeFi lending, much like the broader DeFi space, is relatively unregulated compared to traditional financial systems. This lack of regulation can lead to increased risks, including market volatility and security vulnerabilities. Therefore, it's crucial for participants in DeFi lending and borrowing to be cognizant of these risks and conduct thorough research before engaging in such activities. This cautious approach can help in making informed decisions while navigating the innovative yet complex world of decentralized finance.
