Uniswap v4 is here🦄

Users can LP on v4 through the Uniswap web app and swapping is rolling out over the coming days on web and wallet as liquidity migrates to v4

Live on Ethereum, Polygon, Arbitrum, OP Mainnet, Base, BNB Chain, Blast, World Chain, Avalanche, and Zora Network v4 turns Uniswap Protocol into a developer platform

Made possible with the introduction of hooks ‒ contracts that allow anyone to customize how pools, swaps, fees, and LP positions interact

Hooks mean unlimited new features that drive deeper liquidity and more swaps 🦄

Introducing @unichain — a new L2 designed for DeFi ✨

Fast blocks (250ms), cross-chain interoperability, and a decentralized validator network

Built to be the home for liquidity across chains Unichain is designed to accelerate Ethereum’s scaling roadmap, prioritizing the needs of DeFi users and protocols

Intents-based systems are fragmented, each with their own set of fillers and no unified cross-chain standard

That’s why we teamed up with @AcrossProtocol to propose ERC-7683, a standard designed to solve fragmentation through a universal filler network

⛺️✨ How ERC-7683 works:

+ Users sign a cross-chain order
+ User funds are escrowed in a settlement contract
+ Fillers compete to fill the order on the destination
+ Winning filler executes the action and funds are released

Say hello to the most expansive Limit Order offering in DeFi

Buy and sell any token at your price, on your terms, without having to watch the market

Now LIVE in the Uniswap web app 🦄 How to place a Limit Order:

1️⃣ Open the Uniswap interface
2️⃣ Select the “Limit” tab
3️⃣ Choose input and output tokens
4️⃣ Set exchange rate and duration
5️⃣ Select “Submit”

1/ New beta drop! 👀

Meet UniswapX⚡— a new permissionless, open source (GPL), auction-based protocol for trading across AMMs & other liquidity sources.

TL;DR: Over time, it’ll give users more liquidity, better prices, MEV protection, & gas-free swapping!

Opt-in to the beta👇 2/ UniswapX is next-level aggregation 💪

It outsources the complexity of routing to an open network of fillers who compete to fill swaps at the best prices.

1/ In v4, we’re introducing hooks 🎣

Let’s look at what they are and some hooks we’re excited about.

What ideas do you have?! 2/ Hooks are like plugins. They can introduce code at key points in the lifetime of a pool—like before or after a swap.
This lets developers innovate on Uniswap’s liquidity and security to create pools with custom features.

1/ Today, we’re announcing our vision for Uniswap v4 🦄

We see Uniswap as core financial infrastructure & think it should be built in public with space for community feedback and contribution.

An early implementation of the code can be found here:

github.com/Uniswap/v4-core 2/ Uniswap v4 enables powerful new ways to customize liquidity pools by introducing “hooks”.

Hooks add entirely new functionality to pools, such as dynamically adjusting fees or creating new order types 🪝

1/ Paris, Shanghai, and now Cancun… 🌴

Besides being great cities, they’re also Ethereum hard forks🍴 What exactly is a hard fork, how does it work, and who decides what’s included in them?

Let’s dive in 🤿 2/ First a refresher on blockchains:

Blockchains are a sequence of data made out of “blocks” where each new block builds on the previous, "confirming" it after validator agreement.

Blockchain data can be traced back to the very first block & is unchangeable once validated.

1/ Liquidity rules the world, but how do we find it in DeFi? 🔀

Automated Market Makers (AMMs) and Request For Quote (RFQs) both share common goals of providing liquidity and finding asset prices, but they operate on different principles.

Let's dive into it: 2/ AMMs are self-balancing markets where users can exchange tokens.

Users swap against a large pool of available capital, known as a liquidity pool. The price of the token is based on mathematical curves and user input.

Examples include @Uniswap and @CurveFinance.

ICYMI— we wandered into a dark cave with our friends @WordcelLabs and found a Genie who’s granting our wildest wishes ✨

Today, the Genie is offering us our third and final wish… 🧞: “Yes, my faithful riddlers, you’ve made it this far now it’s time for your last wish…”

🧞: "Welcome back riddlers and @WordcelLabs... it's time for your second wish…"

https://twitter.com/Uniswap/status/1596995167881293825

What shall it be?

🧞: “Thank you for solving yesterday’s cipher and freeing me from that god-awful lamp.” 🧞: “Now that I’m free you can have your first wish!

Reminder:

🚀 I cannot make any tokens pump

👩‍🎨 I cannot give you free NFTs

🔒 I cannot reveal someone else’s seed phrase

So what do you want?”

1/ Uniswap builds public infrastructure that pushes crypto forward.

Today we are excited to introduce Permit2 & Universal Router—new smart contracts that increase the flexibility of token approvals & aggregate ERC20s & NFT swaps into one ✨
uniswap.org/blog/permit2-a… 2/ Permit2 improves the security, UX, and flexibility of ERC20 token approvals with features like:

🤝 Shared approval management across applications
☝️ Universal permits for any token
⏰ Time-bound token approvals
🧺 Batch approvals & revokes for tokens

and more!

1/ As users turn towards DeFi, we want to give you a look under the hood.

Users already know that swapping tokens is as easy as sending an email.

But email & Uniswap are more similar than you may think!

Both are open-source & permissionless foundational internet protocols👇 2/ Uniswap and Simple Mail Transfer Protocol (SMTP) are permissionless protocols—code that is not controlled by anyone.

There are no restrictions on who can send an email like there are no restrictions on who swaps or list tokens on a DEX 📧

1/ One of the most revolutionary things about the Uniswap Protocol is that anyone can become a Liquidity Provider (LP).

Here are a few of our favorite reasons to open an LP position 🚰👇 2/ Earning Fees 🤑

In TradFi and CeFi, big companies provide liquidity — and make tons of money doing so. In DeFi, anyone can market make.

Every time someone trades in your pool, you earn a % of the transaction fee. LPs on Uniswap have earned over $600M this year alone.

1/ Yesterday, some Uniswap LPs unfortunately fell for a phishing scam, a problem far too common in crypto today. To be clear: there was no exploit. The Protocol always was — and remains — secure. Here’s what happened.👇 2/ A phisher airdropped malicious tokens to Uniswap LPs’ wallets. The name of the token directed users to a malicious interface that claimed the users could swap these tokens for UNI.
