Uniswap Labs has launched a tool called the Swap Widget that allows developers to easily embed the Uniswap decentralized exchange app. The integration only requires a single React component and one line of code. It will allow users on third-party apps to swap tokens, join DAOs, wrap assets, and more. The widget supports layer 2 chains such as Polygon, Arbitrum, and Optimism. It has already been integrated into several popular web3 applications, including OpenSea.

Gnosis DAO has voted to spin Gnosis Safe into its own project and launch the SAFE token. This will allow Gnosis to focus and establish itself as a canary chain for Ethereum. It will also allow the team to monetize the Gnosis Safe project and manage the funds in a community-driven way. There will be two SAFE token airdrops, one for everyone who has used Gnosis Safe in the past and one for community members who made the project successful. Gnosis DAO will receive 15% of the total SAFE supply.

Ethereum staking has several drawbacks that Staking Pools try to resolve. Staking pools allow people to deposit ETH and receive rewards without the technical know-how, capital, or locking period that direct staking requires. Depositors also receive tokens that can be redeemed for ETH or spent in other ways. This Twitter thread explains what staking pools are and looks at several different strategies to earn through staking.

This Twitter thread discusses ENS subdomains and how they can be used. The Ethereum Name System (ENS) is a naming protocol that can easily store any digital text records. ENS domains are dynamic NFTs that can have their records adjusted at any time for a nominal gas fee. Subdomains are an extension of ENS domains that have no renewal fees and can be controlled by the registrant, smart contract, or a mixture of both. They can be traded on markets or used by communities to promote brands.

The 4pool represents one of the biggest shifts in the stablecoin economy. Frax and Terra have enough voting power on Curve to redirect emissions to the 4pool. That significantly increases the price stability of UST and FRAX. With more stability, there is lower risk and increased adoption, resulting in more LUNA and FXS burnt. This will mean a reduced supply of these tokens and an increase in demand and price.

Chainlink's Dynamic NFTs (dNFTs) are NFTs that can change based on specific conditions. The metadata on dNFTs can change based on any on-chain or off-chain event, unlocking a wide range of possibilities, for example, they could be used to track property maintenance history or athlete statistics. Chainlink's Data Feeds and Keepers can be used to automatically change NFT metadata based on off-chain events. A link to a blog post explaining dNFTs is provided at the end of the thread.

This Twitter thread covers basic concepts for understanding the Ethereum Virtual Machine. It explains concepts such as Ethereum's machine state, transactions, EVM instructions, opcodes, and more. The thread links to further resources on Ethereum clients and web3.

DeFi protocol Beanstalk Farms was recently exploited for around 25,000 ETH. The attacker used a flash loan to purchase governance tokens to control BEAN. With over 66% control of the tokens, the attacker was able to execute an emergency governance action and withdraw about $180 million worth of assets. The attacker then paid back the loans and ended up with around $75 million worth of ETH. Around $250,000 worth of ETH from the attack was donated to Ukraine.

A group of Monero (XMR) enthusiasts are planning an XMR bank run today. The Monerun is a reaction to the lack of transparency from exchanges over Monero. The community is accusing exchanges of selling more Monero than they actually hold because they believe that customers won't withdraw their funds. Monero's obfuscated ledger technology makes it impossible to verify how much XMR a wallet holds. Many exchanges have suspended XMR withdrawals.
