The change does not require a hard fork, as it can be done by enabling a configuration flag on consensus clients. The Fast Confirmation Rule works by using validator attestations to determine when a block can be safely confirmed. The site aims to inform Ethereum users and manifest shipping fast confirmations on Ethereum. Privy Integrates DeFi Yield --------------------------- Privy, an embedded wallet infrastructure provider, [launched](https://privy.io/blog/earn-on-balances-with-privy?utm_source=twitter&utm_medium=organic) Earn, a feature that enables applications to generate DeFi yield on idle onchain balances held in Privy wallets. Using Privy’s APIs, developers can enable fund deposits into vaults, liquidity withdrawals, and configure revenue sharing from vault returns. The feature initially supports ERC-4626 vaults on the Morpho lending protocol, with planned integrations for Aave and Kamino Finance. Vault strategies are curated by Steakhouse Financial and Gauntlet. Privy enables apps to integrate crypto wallets with Web2 login methods such as SMS, email, Google, X, and Farcaster. It also supports cross-application wallet functionality, enabling users to access the same embedded wallet across multiple apps. Curve Launches FastBridge ------------------------- Curve Finance [launched](https://x.com/CurveFinance/status/2033606502041215194) FastBridge, a bridging layer powered by LayerZero that enables fast withdrawals of crvUSD from L2 networks to Ethereum. The system combines LayerZero’s cross-chain messages with an Ethereum vault that releases pre-minted crvUSD to the user, which is backed by the pending canonical transfer. Once the canonical withdrawal finalizes, the bridged tokens refill the vault. The design reduces withdrawal times from the typical 7-day optimistic rollup delay to around 15 minutes, enabling faster arbitrage and helping keep crvUSD prices aligned across chains. FastBridge is now live on Arbitrum, Optimism, and Fraxtal. x402 Supports Any ERC-20 ------------------------ x402, the payments protocol by Coinbase that enables onchain transactions over HTTP, [now supports](https://x.com/CoinbaseDev/status/2033619844403499099) any ERC-20 token  x402 turns HTTP 402 "Payment Required" status code into a functional onchain payment mechanism, enabling frictionless, pay-per-use payments for APIs, AI agents, compute, and content. Developers can integrate x402 with minimal code, using existing HTTP infrastructure, to accept payments in any ERC-20 token.
