NFT marketplace OpenSea is now accepting ApeCoin. ApeCoin is now the largest metaverse token by market cap. It has grown more than 33% over the last week.

Yuga Labs' Otherdeed NFT mint raised around $320 million. Otherdeeds are NFTs representing virtual plots of land in Yuga Labs' upcoming Otherside metaverse project. A total of 55,000 NFTs sold for 305 ApeCoin each. Gas fees soared during the sale, with some buyers paying up to 5 ETH in fees alone. The sale also caused disruptions to the Ethereum network, slowing down transactions on Ethereum-based services and causing users to lose gas fees due to failed transactions. Yuga has apologized for the disruptions and has promised to reimburse users gas fees associated with failed transactions.

The Basepool is a proposed partnership between MakerDAO and Curve Finance to form a new Curve stableswap pool consisting of DAI, USDC, USDP, and GUSD.

A recent attack on the Rainbow Bridge was stopped automatically with no funds lost. The Rainbow Bridge is a service on Aurora, an Ethereum-compatible scaling solution built on Near that allows users to transfer tokens between the Ethereum, Near, and Aurora networks. Its architecture is designed to resist attacks, and the attempt resulted in the attacker losing 2.5 ETH due to fees. The Rainbow Bridge team will redesign parts of its security to make future attempts more costly for attackers.

This Twitter thread explains some of the flaws in Yuga Labs' Otherdeeds smart contract. The contract used the ERC721Enumerable extension in order to make the NFT's token IDs trackable, but using it caused a significant increase in gas fees. Using ApeCoin to buy the NFTs caused users to pay more in gas than if they had used ETH. The minting method used was also inefficient.

Solana crashed for nearly seven hours on Saturday due to bots flooding the network while using an NFT minting tool. The bots submitted more than 4 million transactions a second and generated more than 100 Gbps in traffic. Validator operators were able to restart the network by coordinating through Discord. Solana's token price dropped during the outage but has mostly recovered since.
