# Layer 2 Summer | Weekly Recap *Author: Ryan Sean Adams* *Published: May 29, 2021* *Source: https://www.bankless.com/de/layer-2-summer-weekly-recap* --- Dear Bankless Nation, Ethereum’s layer 2 is going to hit crypto like a tidal wave. 🌊 Here’s the setup… Ethereum on DeFi exploded in 2020…*ding! ding! ding! product market fit! 🚨* The problem? We don’t have enough trustless blocks for our DeFi transactions. Too much demand and not enough supply means high transaction costs. *Users priced out. Apps priced out.* So along comes [Binance Chain](https://bankless.ghost.io/the-good-the-bad-and-the-ugly-of/)…an Ethereum computer inside a centralized casino. Not ideal, but it works out of the box with DeFi tools. Transaction demand explodes! Then comes Polygon. Still not a layer 2 yet (*remember—layer 2’s are fully secured by Ethereum*) but it’s more socially aligned with DeFi and has an [ambitious roadmap](https://twitter.com/0xPolygon/status/1397558139256377345?s=20), including [infinite sidechains](https://twitter.com/0xPolygon/status/1397558151436636162?s=20)! Demand explodes even more! **We have the data.** People want Ethereum’s DeFi without the massive gas bill and there’s billions locked in Polygon to prove it. (*Aave w/ $7B locked alone *👀). That’s where we find ourselves now as we enter summer 2021. But by the time you read this Arbitrum [will have deployed on mainnet](https://twitter.com/RyanSAdams/status/1398383016385339395?s=20). (*We’ve invited them [on the show](https://www.youtube.com/c/bankless) next Tuesday 👀*). [Arbitrum](https://offchainlabs.com/) will be first true layer 2 with full EVM compatibility, making it easy for developers to deploy DeFi apps. I expect it will ship with DeFi apps. We’ll see how Arbitrum fairs on the market, but builders seem excited (*Uniswap community [begging](https://gov.uniswap.org/t/deploy-uniswap-v3-to-arbitrum-mainnet/12451) to deploy on it!).* Then after Arbitrum comes [Optimism](https://optimism.io/)—July? Many of our favorite DeFi protocols like Synthetix and Uniswap have already committed to deploying on it. All the while we have [Starkware Layer 2](https://www.youtube.com/watch?v=zZN8k70o09I) applications like [dYdX](https://bankless.ghost.io/how-to-trade-on-the-dydx-rollup/), [immutable X](https://www.immutable.com/), and [DeversiFi](https://www.deversifi.com/) gaining steam while [Loopring keeps chugging away](https://defipulse.com/loopring). Fire up your [block explorers](https://optimistic.etherscan.io/) folks. It’s going to be a fun summer. But let’s take it a week at a time! Here’s what lined up for next week: - William’s going to show you how to use Uniswap V3 - We talk to Eric Wall the ALT SLAYER (*was he wrong about ETH?*) - David has a piece on the future of work. Let’s get to the recap. - RSA *P.S. We’re hiring an elite writer to join our team as an [editor](https://cryptocurrencyjobs.co/marketing/bankless-editor-writer/)! Think you’ve got what it takes?
