UltraYield: Vault Curator on Morpho and Euler, Fees and Risks

UltraYield's website footer says the site is run by Ultra Technologies LLC, as a non-custodial interface that doesn't provide custody or discretionary management ¹. Two partners connect the brand to Edge Capital:

• Euler's public labels list a curator called "Edge UltraYield" whose multisig is the same address Morpho's API assigns to UltraYield ³⁶.
• Hyperbeat's docs call UltraYield "part of the Edge Capital Group" ⁷.

Edge Capital's own website is restricted to accredited and professional investors. It doesn't publicly set out the group structure or say where Ultra Technologies LLC is registered.

UltraYield labels its USD, ETH and BTC vaults "Regulated" but doesn't say which regulator or licence that refers to ¹. Treat the label as unverified.

As a curator, UltraYield chooses which Morpho markets a vault may lend to, caps exposure to each and sets fees. On Morpho, the vault roles are:

• Owner: appoints the curator and safety roles.
• Curator: sets markets, caps and fees.
• Allocator: moves deposits between allowed markets.
• Sentinel (Guardian in V1): can cut risk or veto pending changes.

Timelocks delay most curator changes ⁹. In UltraYield's four Core V2 vaults, one UltraYield multisig holds all four roles ⁴.

On the Base V1 vault, Morpho's API shows UltraYield's address as owner, with the curator and guardian slots unset and a three-day timelock ⁵. The website also lists vaults it curates for others: Edge UltraYield USD1, Midas mBASIS and mEDGE, LoopedBTC and Plasma syrupUSD ¹. UltraYield is also the strategist for Hyperbeat's hbHYPE vault on Hyperliquid, which charges a 15% performance fee ⁷.

UltraYield's own USD, ETH and BTC vaults on Ethereum work differently from Morpho lending. The USD vault accepts USDC and USDT and puts the money into funding-rate and basis trades. These pair long and short positions across exchanges to earn funding payments rather than bet on price ².

On October 23, 2026, its counterparty report showed positions at:

• Bybit
• Hyperliquid
• Lighter
• OKX
• Aster
• Binance ²

Terms for the USD vault ²:

• Performance fee: 10%.
• Management fee: 0.5%.
• Withdrawal fee: none.
• Withdrawal period: three days.
• Performance buffer: UltraYield holds back up to 20 basis points of NAV to absorb negative days. It calls this discretionary and not a guarantee.

• Exchange counterparty risk. The own-brand vaults keep assets on centralized exchanges. A venue failure or freeze could cause losses that smart contracts can't prevent ².
• Strategy risk. Funding rates can turn negative. UltraYield's vault page says returns "may be negative" ².
• Concentrated control. One multisig holds every role on the Morpho V2 vaults ⁴.
• Unclear regulatory status. The "Regulated" label names no regulator ¹.
