Shadow, a smart contract indexing platform, launched univ3.xyz, a dashboard designed to analyze Uniswap pool activity and liquidity dynamics. The dashboard leverages Uniswap v3 shadow events, which are offchain event logs that provide extensive data and insights beyond what is available in the original onchain contract. Shadow events can be retroactively added to any deployed smart contract without altering its functionality. The process uses a real-time database sync, eliminating the need for RPC calls or external APIs. Shadow aims to simplify data pipelines and provide hosted node infrastructure for anyone looking to build an onchain data indexer.
Caldera, a rollup-as-a-service infrastructure provider, raised a $15 million Series A funding round led by Founders Fund, bringing its total funding to $25 million. The fresh capital will be used to develop the Metalayer, a unifying layer for L2 and L3 chains. The Metalayer enables execution across rollups with a single transaction. Caldera launched a pilot NFT mint on the Metalayer, allowing users to mint NFTs across 18 Caldera rollups on testnet. Caldera supports custom rollup deployments on ZK Stack, OP Stack, Polygon CDK, and Arbitrum Orbit frameworks. Chains deployed on Caldera, such as ApeChain, RARI Chain, and Manta Network, collectively secure over $800 million in TVL.
Polygon CDK has integrated Circle's Bridged USDC Standard, allowing chains deployed on the stack to implement an upgradeable version of bridged USDC. The standard enables smooth future upgrades to native USDC without needing code changes. The integration minimizes liquidity fragmentation by eliminating the need for users to migrate their bridged USDC to native USDC.
