Uniswap (UNI) – The Leading Decentralized Exchange

And that's around 216 million plus SHIB at the moment. Right now, I'm buying and accumulating. Hopefully, in the near future, the economy picks up, and we ride the bull into new ATHs. I might swap some of my tokens over at either UniSwap or Houdini Swap for some more SHIB.

Anyway, I am stacking up on LTC seeing a lot of Redditors lately being anti LTC. So I was wondering where does everyone stack or swap their LTC nowadays? Crypto.com and Coinbase for example have high fees when buying LTC. I was thinking of SushiSwap, Houdini Swap, or Uniswap or any alternatives you can think of that are DEXes.

But I suggest if you have a huge amount of crypto sitting in a CEX right now, it’s high time you take that off of CEXes and swap that over to Uniswap, PancakeSwap, Houdini Swap or whatever DEX swapping platform you use (maybe Curve?).

Along with Uni and Sushi I had been looking at other Decentralized exchanges. One I had been looking into was Bancor, they had announced a new liquidity mining program that I wanted to take part in but I was nervous to risk a lot of money in it.

The DeFi landscape has witnessed the rise of industry giants like Uniswap and Aave, gaining widespread recognition. However, amidst these prominent platforms, a group of dynamic companies is making significant strides in the Web3 revolution. In this article, we highlight a selection of innovative companies that have caught our attention with their valuable contributions to the DeFi ecosystem. What sets them apart is their compelling approach to directly engage with their communities. Before delving into their unique strategies, let’s explore these remarkable companies in greater detail.

One popular DeFi application built on Ethereum is Uniswap. Uniswap is a decentralized exchange protocol that allows users to trade ERC-20 tokens directly from their Ethereum wallets. It utilizes smart contracts to enable trustless and automated token swaps, providing liquidity through liquidity pools.

Lets look the events of Open Zeppelin’s ERC20 token contract:

ERC-777 is difficult to implement properly, due to its susceptibility to different forms of attack(opens in a new tab). It is recommended to use ERC-20 instead. This page remains as a historical archive.
