Two vaults, daily rewards, automatic compounding, and first-loss protection. Get started on [stake.lido.fi/earn](https://stake.lido.fi/earn) * * * Block-in-Blobs (BiB) EIP-8142 ----------------------------- Ethereum researcher Toni Wahrstätter [introduced](https://ethresear.ch/t/blocks-are-dead-long-live-blobs/24611) Block-in-Blobs (BiB) EIP-8142, which proposes to encode transaction data into blobs, similar to EIP-4844, so validators don’t need to download every transaction. BiB makes data availability explicit and efficient, rather than implicit. While zkEVM [removes](https://x.com/ladislaus0x/status/2041585393183719719) the need to re-execute, it does not eliminate the need to access transaction data. BiB packs RLP-encoded transaction bytes into blobs with cryptographic commitments, allowing validators to then verify the commitments and use data availability sampling (DAS) to ensure all data is available, maintaining full security, drastically reducing bandwidth requirements, and scaling Ethereum L1. Biconomy Introduces ERC-8211 ---------------------------- Biconomy, a cross-chain execution protocol, has [introduced](https://x.com/biconomy/status/2041516284635120108) Smart Batching ERC-8211, a proposed Ethereum standard that transforms transactions into dynamic, multi-step programs. It enables onchain agents and users to execute complex workflows with a single signature, without deploying custom contracts. The standard addresses the limitations of current static batching, where parameters are fixed at signing and can become outdated. Instead of hardcoding values, smart batches fetch real-time onchain data, validate it against constraints, and execute only when predefined conditions are met. ERC-8211 enables fully composable, cross-protocol and cross-chain workflows, reduces failed transactions and leftover balances, and provides a shared execution standard for autonomous onchain agents. KPK Launches A Web App  ----------------------- KPK, a DAO treasury manager, [launched](https://x.com/kpk_io/status/2041538765290623142) the KPK App, a web interface for tracking and allocating assets across KPK yield strategies. The app features live performance data across all strategies, risk tiers tailored to different user profiles, and unified position tracking across both Vaults and Funds. KPK currently offers two vault types. Prime Vaults are designed for capital preservation and high liquidity, relying on established collateral like ETH and strict risk controls. Yield Vaults, by contrast, target higher returns through broader collateral exposure and active rebalancing, often focused on stable assets. KPK, originally incubated by Gnosis in 2021, manages treasuries for organizations such as ENS DAO. Privy Enables Swaps Via Uniswap ------------------------------- Privy, an embedded wallet infrastructure provider, [integrated](https://x.com/privy_io/status/2041532071026307555) swaps powered by Uniswap, allowing developers to support conversions between assets with a single API call. Privy abstracts away the complexity of routing, calldata, slippage, and transaction execution, while leveraging the Uniswap API for liquidity. Privy enables apps to embed crypto wallets using familiar Web2 login methods such as SMS, email, Google, X, and Farcaster.
