September was a jam-packed month for YO, full of new developments, including the launch of yoEUR, YOligarchy, new markets, and an abundance of new integrations to bring you the highest performing yield. We also reached new heights, including becoming the largest yield aggregator on Base and the 14th largest protocol overall. Read on as we dive into our biggest announcements from September. ⬇️

yoEUR

Starting the month off strong, we launched our latest vault, yoEUR, on September 5th. This launch marks the first-ever multichain euro-denominated stablecoin vault. Euro stablecoins are a growing market, hovering around ~$500m/~$600m. With the euro itself rallying over 13% against the dollar this year, demand for euro-denominated opportunities is rising.

yoEUR is designed to capture that momentum. By routing deposits into top-performing EUR pools across DeFi, backed by Exponential's risk framework, the vault turns idle euro assets into productive capital. Users can now earn sustainable yield on their EURC through one simple deposit, with future integrations unlocking advanced strategies such as looping, yield markets, atomic swaps, and more.

yoEUR has already climbed past $900k TVL, boosted by 7% base yield plus 3% extra Merkl rewards, a powerful combo in a market hungry for euro-denominated returns.

YOligarchy Ambassador Program

This month, we launched the YOligarchy Ambassador Program, built for creators and YOverse supporters who want to do more than post-and-ghost. We’re looking for creators who want to explain DeFi yield clearly, grow with our community, and help users make sense of yield optimization across chains and protocols. This entails creating YO content on X and tagging us in your best efforts.

Winners have been announced every Wednesday beginning September 10, and received the coveted "YO KNIGHT" role. Week 5 began on October 1st so don’t miss out!

We’re working on the next season of the program, so keep an eye out for updates on X!

Treasure Chest

Season 1 of Treasure Chest launched on September 18th as a surprise reward game for loyal depositors.

Depositors had the chance to earn up to 15 keys during Season 1. Each key unlocked a chest with a random multiplier between 0.1× and 100× the depositors’ average daily points. Off-app DeFi activity (Morpho, Euler, Pendle, Mitosis, etc.) didn’t count this season to keep the points program balanced and prevent dilution.

We had a total of $2.46M deposited as part of the Treasure Chest campaign, with the most popular vault being yoBTC, followed by yoETH.

Season 1 wrapped on September 30th. Stay tuned for Season 2!

Loopy Lenders

This month also brought new automated looping markets from IPOR!

First was a new Clearstar-fueled yoUSD Loooper vault. This vault does the looping for you, targeting ~30% APY while delivering a 6x YO points boost. The vault hit capacity out of the gate before being immediately raised. And once again, the cap was hit at $500k.

Second was a new Clearstar-fueled yoETH Loooper vault. This vault targeted ~18% APY while delivering a 5x YO points boost.

As a reminder, these are the avenues to loop yoTokens:

• Morpho: yoETH, yoUSD
• Euler: yoETH, yoUSD, yoBTC
• Contango: yoETH, yoUSD
• IPOR Fusion: yoETH, yoUSD

Morpho Markets

Morpho is built for efficiency, matching lenders and borrowers directly to deliver sharper rates and deeper liquidity. That design pairs naturally with YO’s mission to make capital as productive as possible.

With our new markets live, users can now put yoUSD and yoETH to work on Morpho. Lend USDC or WETH into Clearstar-powered vaults and earn APYs, or borrow against deposits at up to 91.5% LTV. From there, loop positions to compound exposure while stacking YO Points.

Whether you prefer stable yield or ETH leverage, these markets offer flexibility and efficiency, with YO managing risk across vaults and Morpho ensuring the best rates.

New Pendle Markets

We dropped fresh yoEUR, yoETH and yoUSD yield markets this month!

PTs (Principal Tokens) to lock in stable yield:

→ yoETH PT: 8% fixed APY until Mar 25, 2026.

→ yoUSD PT: 16% fixed APY until Mar 25, 2026.

→ yoEUR PT: 8% fixed APY until Mar 25, 2026.

The song remains the same: trade yield, lock in to market-leading yields, and farm YO points.

New Integrations

From infrastructure to applications to wallets, the YOverse is rapidly expanding with new integrations. Here are some of the highlights:

• Tuyo is the first wallet with native YO integration, offering one-click access to DeFi yield. Instead of hopping between dApps and protocols, you can allocate to yoVaults directly from their wallet interface.
• Velvet took the initiative to add all four yoVaults! Velvet now gives users one-click access to yoTokens from any asset, no bridging or extra steps required. Positions can also be tracked in the Velvet dashboard while YO's rebalancing algo and risk engine work in the background to deliver the best yield for Velvet users.
• Extra Finance added yoUSD and yoETH to their XLend, allowing up to 75% LTV.
• Harvest Finance’s WETH Autopilot is now plugged into Cleartstar's ETH Reactor, adding more liquidity to Morpho's yoETH loopers market.
• Earnbase and Vaults.fyi are now tracking yoEUR.
• Axal integrated yoUSD into their app.

That’s a wrap on September. Stay tuned for more exciting updates from YO next month!
