Overnight Finance

Overnight Finance is an asset management protocol that sells passive stablecoin yield products backed by lending, stable-pool and delta-neutral strategies. At the 2026-08-16 survey it held about $9.97M across Blast, Base, Arbitrum and a negligible Linea balance, under ten percent of our size floor. One practice advising 100 households moves $1M to $8M into a venue on the same research, and at this size that book becomes the exit crush. We do not open an individual review until the protocol clears the size floor, whatever the strategy’s quality.

Review triggers: events that reopen the verdict
• TVL sustained above the retired TVL threshold for 30 days
• The delta-neutral strategy publishes position-level disclosure sufficient to underwrite the basis exposure

Watched nightly: a warning on its venues or files, or a cited document that changes, reopens the memo. The first confirmation is due 2026-11-15.

The research file

Mechanism applicability

Overnight issues rebasing USD+, USDT+ and related tokens against portfolios of DeFi strategies. The strategy charter includes lending deposits, stable-to-stable pools and delta-neutral exchange-traded strategies; ETS positions borrow a volatile asset against collateral and pair it with stablecoin liquidity, leaving gamma and rebalancing risk even when delta is hedged. The measured collateral remains below the shared version-1 size floor, so we do not open an individual review.

Current observation and perimeter

The DefiLlama protocol API read on 2026-08-16 classified Overnight Finance as CDP and reported approximately $9.97M: about $9.12M on Blast, $0.48M on Base, $0.37M on Arbitrum and a negligible Linea balance. Current Overnight contract documentation lists deployments across those and additional networks with zero measured balances. The registry corrects the stale Base-and-Arbitrum-only description to cover the current networks with nonzero balances in the survey.

Control and exit applicability

PortfolioManager-controlled strategies can stake, unstake and claim rewards within the published charter; holders depend on those controls, external lending and AMM venues, oracles, bots and collateral values. USD+ can experience a negative rebase when collateral value falls below supply. Mint and redeem calls pass through Exchange contracts, and actual redemption depends on liquidation value and available strategy liquidity rather than the displayed net asset value alone.

Why the class rule decides

The increase from roughly $1.1M to $9.97M and the Blast concentration are meaningful, but the system remains one tenth of the size floor. A $1M to $8M advised book would still be material to the entire portfolio before a Blast or strategy exit is stressed. We do not open an individual review until the protocol clears the size floor. Reopen after reconciled TVL remains above the size floor for 30 consecutive days, then review every strategy, position-level basis and gamma risk, governance and bot controls, incidents, legal access, proposed-size redemptions and named simpler alternatives.

Research status

This is a capacity-unproven record for Overnight Finance, not a quality rejection or approval. Reported TVL says how big the venue is, not what the client owns, who can change the rules, or how a position exits at a proposed size. The individual review opens when the protocol clears the size floor.

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

Inherited controls

The research above describes the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The layer with the most administrative power sets the position’s effective control; that describes control, not quality or suitability.
