Yearn Finance Launches Horizon Vaults on Base

**Yearn's Katana vaults deliver impressive APYs through multiple stacked yield sources:** - **Extrinsic yield**: Bridged assets earn yield in low-risk Morpho vaults on mainnet while locked - **Katana APY**: Real yield from strategies, similar to standard Yearn vaults on mainnet - **KAT token rewards**: Calculated using $1B FDV assumption for 10B token supply (tokens unlock Feb 20, 2026) - **Base rewards**: Fixed 35% APY boost for USDC/USDT via Merkl campaigns - **App rewards**: Variable APY boosts for specific pools through additional Merkl campaigns - **Deposit bonus**: Extra rewards for early depositors (before Sept 1) The combination of these yield sources creates the **40%+ APYs** seen on stablecoin vaults. Each component is clearly displayed in vault tooltips. *Always verify where your yield comes from before depositing.*

**Yearn vaults on Base experienced exposure to Moonwell markets** during an oracle malfunction incident. - All funds were **successfully withdrawn with zero losses** - Vaults continue operating normally - Quick response prevented any financial damage The incident highlights the importance of rapid response protocols in DeFi operations. Despite the initial exposure risk, Yearn's team managed to extract all positions safely before any losses occurred.

Yearn Finance has launched a new USDC vault that leverages API3's Oracle Extractable Value (OEV) network to boost yields. The vault represents a shift in how liquidation value is captured in DeFi lending markets. Previously, liquidator bots competed through gas price auctions, with most value going to validators. API3's OEV network changes this by: - Obscuring oracle data - Auctioning data to liquidators - Redirecting value from validators to protocols Key Benefits: - Enhanced yield potential - Exclusive use of API3 oracles - Increased oracle diversity [Learn More](https://forum.morpho.org/t/new-oev-boosted-vaults-by-yearn-api3/1833)

Yearn Finance announces yBOLD, a yield-bearing version of BOLD built on Yearn V3. Key features include: - Oracle-free architecture - Permissionless access - Automatic yield optimization - Zero entry/withdrawal fees - Integration with Yearn's Dutch Auctions The upgrade enables users to earn yields while maintaining BOLD exposure. Additionally, @asymmetryfin is developing sUSDaf, among other yield-bearing Liquity V2 projects in development. Previous implementations showed potential for: - Use as productive collateral on platforms like Euler - Advanced yield strategies via Spectra and Pendle - Exposure to 15+ fork rewards through Stability Pool deposits
