OpenSea says it was not affected by Magic Eden incident, blocks sales of more than 3,000 stolen NFTs

OpenSea said its platform and smart contracts were not affected by the security incident involving Magic Eden and Limit Break, according to a statement posted on X by Chief Technology Officer Chris Maddern. The company said it is adding warning banners across its platform and linking users to approval revocation tools. Maddern also said OpenSea has already flagged known affected ERC-721 NFTs and prevented them from being sold on the marketplace. Any newly identified exploited NFTs will be automatically flagged as well, with the goal of limiting attackers’ ability to receive offers tied to those assets. As of the latest update, more than 3,000 NFTs have been marked as stolen and blocked from trading. OpenSea said it will keep working to reduce the impact of the broader industry security incident on users.

Tapeout Tries to Recreate Chip Logic On-Chain With ERC-1155 and ERC-721

Tapeout.net is pitching an unusual idea: building an on-chain version of an integrated circuit by mapping core chip components to token standards. In the project’s design, ERC-1155 tokens represent transistors, while ERC-721 tokens represent the circuits that connect them. The article argues that this mirrors how real-world chips are built from basic units, then combined into logic gates, arithmetic units, and eventually complex processors such as GPUs and CPUs. It also points to a blockchain-native equivalent of a chip clock. In conventional hardware, transistors and circuits alone do not run unless a clock frequency drives the system. The author says block production on a blockchain can serve that role, with each new block acting like a recurring pulse for an on-chain chip. Tapeout was first launched on BNB Chain and is already live, with enthusiasts experimenting by minting “transistors” and designing their own “chips.” While the piece describes the project as primitive in terms of clock speed and current functionality, it presents the idea as a new line of thinking for crypto: whether semiconductor logic, and eventually parts of AI hardware, software, and compute, could be explored through decentralized architectures.

What NFTs Are and How On-Chain Ownership Works

NFTs are unique crypto assets used to verify ownership of digital items. Commonly issued via ERC-721 and ERC-1155, they record creation, sales, and resale history on public blockchains.

Axie Infinity to Begin Land Item Contract Migration on July 7, With Trading Paused During the Process

Axie Infinity announced that it will migrate Land Items to a new smart contract supporting REP-15, a move designed to prepare for integration with Terrariums. The migration is scheduled to begin at 15:00 on July 7 and will remain in progress until completion. During the process, Land Items will continue to follow the ERC-721 standard, but listed items will be delisted, active items will be locked, and all Land Item-related trading will be temporarily suspended. Once the migration is complete, the platform will mint the same number of items with the same IDs and return them to users’ wallets. According to the official update, no user action is required, and a separate announcement will be issued once normal trading and usage resume.

Axie Infinity has announced that it will migrate its Land Items to a new smart contract supporting REP-15, a move intended to prepare for integration with Terrariums. The migration is scheduled to begin at 15:00 on July 7 and will continue until completion. During the process, Land Items will remain under the ERC-721 standard, but marketplace activity and related transactions will be temporarily suspended. Existing listings will be removed, while active items will be locked throughout the migration window. Once the process is completed, the platform will mint replacement items in equal quantity and return them to users’ wallets using the same token IDs. Axie Infinity stated that no manual action is required from users, and a separate announcement will be issued when trading and usage resume normally.
