Yearn Launches OEV-Boosted USDC Vault with API3 Oracles

A critical security tool for multisig wallet signers has emerged as a potential safeguard against major exploits. **The Tool** - [safe-tx-hashes-util](https://github.com/pcaversaccio/safe-tx-hashes-util) is recommended for all multisig signers - Designed to verify transaction hashes before signing - Could have prevented the $1.4B ByBit hack **Why Multisig Matters** - Splits control across multiple signatures (e.g., 2-of-3 required) - Eliminates single points of failure - Essential for DAOs, teams, and large funds **Popular Solutions** - Gnosis Safe - Argent - Compatible across Ethereum and EVM chains Multisig wallets aren't just for large organizations—they're a fundamental security layer for anyone managing shared crypto assets.

Yearn has structured its yChad multisig with a notably decentralized approach: only 1 of 9 signers is from Yearn itself, while the other 8 are recognized figures from across the space. This configuration positions yChad as potentially the most decentralized multisig in DeFi. The multisig serves as Yearn's primary security mechanism, managing treasury operations and critical protocol actions. **Key characteristics:** - 9-signer setup with minimal internal control - Manages mission-critical treasury and protocol functions - Slower transaction signing provides additional security through extended review periods The deliberate delay in transaction execution allows multiple parties to scrutinize actions before implementation. Full technical details available in [Yearn's documentation](https://docs.yearn.fi/developers/security/multisig).

Yearn Finance has released guidance on proper multisig wallet configuration, emphasizing that simply using a multisig isn't sufficient protection. The protocol outlined three essential steps for effective multisig strategy, though specific details weren't provided in the announcement. The team stressed that proper configuration can mean the difference between security and exploitation. **Key Points:** - Multisig setup requires careful strategic planning - Configuration details matter as much as using a multisig - Three specific steps can prevent common security issues - Additional DeFi security guidance promised Yearn indicated this represents just one aspect of comprehensive DeFi security, with more educational content planned for release.

Yearn Finance has begun distributing revenues to YFI token holders who stake their tokens. Users can stake through three methods: - **Direct veYFI staking** - Lock YFI tokens to receive veYFI and earn rewards - **Liquid locker protocols** - Stake through platforms like 1up, Cove, or StakeDAO - **Boosted vault deposits** - Earn enhanced yields on vault deposits **How rewards work:** Every two weeks, veYFI holders vote to direct dYFI rewards to specific vaults. Your reward rate depends on your veYFI balance: - Base rate: 10% of possible rewards (1x boost) with no veYFI - Maximum: 100% of rewards (10x boost) with sufficient veYFI Liquid lockers allow YFI holders to rent out their voting power to vault depositors. Depositors pay a small fee but receive significantly higher yields through borrowed boost power. Rewards are paid in dYFI, which can be converted to YFI or sold on the market. Vault rewards auto-compound, while dYFI rewards require manual claiming through the liquid locker interface. A [boost calculator](https://docs.yearn.fi/contributing/governance/veyfi-calculator) helps users determine optimal veYFI amounts for their deposits.

**Yearn's OEV-boosted USDC vault on Morpho has received an A rating**, joining highly-rated vaults from Stakehouse and Gauntlet. The vault utilizes **Oracle Extractable Value (OEV) technology** to recapture value that would otherwise be lost to MEV bots, redirecting it back to depositors as enhanced yield. **Key highlights:** - A-grade rating validates vault's risk management and performance - Part of Yearn's expanding curation services on Morpho - OEV-boosting technology provides sustainable yield enhancement - Previously surpassed $10M in deposits milestone Yearn continues to demonstrate its **best-in-class vault curation and monitoring capabilities** across the Morpho ecosystem, offering institutional-grade DeFi products with enhanced risk assessment.
