Three ARM deployments are currently live: the stETH ARM, eETH ARM, and sUSDe ARM. This document covers asset risk, counterparty exposure, smart contract and governance controls, NAV mechanics, and monitoring surface. For deployment-specific contract addresses, fee configuration, and audit history, see the ARM documentation. ARM Asset Exposure Before evaluating risk by category, it helps to understand what an ARM Vault actually holds at any given moment. ARM Vault capital is split between two states: Redemption inventory: redeemable assets acquired at a discount on secondary markets, which are sent through the underlying protocol's redemption queue for 1:1 redemption. Available liquidity: base-asset capital not currently being processed through the redemption queue. These funds are routed to an external lending market or are ready to be sold for discounted redeemable assets on the secondary market. The ratio between these two categories is not fixed. It is a function of current arbitrage flow, operator pricing bands, and the configured liquidity buffer. 1. Asset Risk Profiles and Redemption Queues stETH, eETH, and sUSDe each carry risks that belong to their issuing protocols, and those risks apply to any holder of the asset. The ARM adds one incremental risk on top: redemption exposure duration. When an ARM Vault redeems assets through the issuing protocol's own redemption path, it stays locked there until it clears back to base collateral at 1:1. The length of that lock, and the conditions that stretch it, differ per asset. stETH ARM: stETH ARM batches clear through Lido's redemption queue, which normally processes exits between one to five days. Validator-exit congestion can stretch the queue to multiples of its normal length, and congestion tends to arrive with the same volatility that widens the stETH discount. eETH ARM: eETH ARM batches face a structurally longer redemption path than stETH ARM batches: redemptions route through Ether.fi 's exit process, and where the underlying ETH sits in EigenLayer restaking positions, unwinding adds EigenLayer's redemption escrow as a second sequential lock. That layered path gives the eETH ARM a longer baseline exposure duration than the other ARM deployments. The eETH redemption queue typically processes within one to seven days. sUSDe ARM: sUSDe ARM batches pass through Ethena's redemption cooldown before returning base collateral to the vault. The cooldown runs short in normal conditions and extends under stress. sUSDe redemptions are typically processed in one day and have the shortest average redemption cycle out of the three ARM deployments. Under market stress, sUSDe redemptions may take up to five days. 2. Protocol Exposure for Lending Yields When arbitrage opportunities are absent or below the ARM's lending market threshold, idle base-asset capital routes to an external lending market. This exposure is separate from and additive to the redeemable asset risk. Morpho: The stETH and eETH ARMs route idle WETH to the Morpho WETH ARM Vault. There is no hard cap on the lending share of the book, and allocation is governed by the ARM's configured liquidity buffer. This exposure carries smart contract risk and utilization risk, which affects withdrawal timing during periods of high borrowing demand. The Morpho WETH ARM Vault allocates to highly liquid, ETH-based markets that have been both externally audited and vetted by the Origin Protocol team. Aave V3: The sUSDe ARM routes idle USDe to Aave V3. This exposure carries smart contract risk and utilization risk, which affects withdrawal timing during periods of high borrowing demand. Aave V3 has a long audit history and a track record securing billions of dollars in capital. 3. Automated vs. Manual ARM Functions ARM is a hybrid system. Some functions are permissionless and require no operator involvement. Other functions are operator-controlled and require active management. This section breaks down which functions are permissionless, and which are operator controlled. allocate(): Permissionless Rebalancing allocate() is a rule-based rebalance function callable by any address. It moves idle capital between the ARM Vault and the active lending market to maintain the configured liquidity buffer. allocate() does not control ARM's entry into redemption queues. Assets enter the redemption queue based on the ARM Vault’s bids being filled and operating batching. Pricing bands are set by the operator, not by allocate(). If the operator is offline, allocate() continues to function, existing pricing remains active, and completed withdrawal batches can still be claimed. New pricing updates and withdrawal batching require operator intervention. Operator Controls: Pricing, Batching, and Market Switching The operator controls three functions that require ongoing judgment: Pricing bands. The ARM's bid price range is set by the operator, calibrated to redemption queue depth and lending market rates. Within those bands, the ARM's quotes are automated to remain competitive across DEX aggregators. Redemption batching. The operator initiates and manages redemption batches, submitting assets to the underlying protocol's redemption queue. Existing batches in the queue continue to progress regardless of operator availability. Lending market switching. The ARM connects to each lending market through an adapter, and the operator can switch the active adapter, but only to markets on the owner-approved supportedMarkets whitelist. The operator cannot route ARM capital to an arbitrary adapter. ARM's bid price for redeemable assets is set by the operator based on observed withdrawal queue depth, lending market rates, and market price data. There is no external price oracle feeding ARM's pricing function. This eliminates oracle manipulation risk for the ARM's core arbitrage function. Rather than using an oracle, the operator sets the pricing band manually. Within the pricing band, the ARM's bid price can move automatically to stay competitive across DEX aggregators. Operator buy/sell prices are constrained to a tight range around an owner-only crossPrice anchor (_validatePrices). This creates pricing guardrails and acts as a safeguard for LPs. NAV is calculated at the time of the withdrawal request, not at claim time. Two cases follow from this: If NAV decreases between request and claim, the claimant receives the lower claim-time NAV. If NAV increases between request and claim, the claimant is capped at request-time value. This protects remaining LPs from absorbing losses or socializing gains that materialize after a withdrawal request is already queued. LP exits follow a two-step process. The LP submits a withdrawal request; the ARM processes the request to make it claimable. The minimum delay is 10 minutes. If sufficient vault liquidity is available, the request is claimable after that minimum. If vault liquidity is unavailable, the request remains pending. Although 95% of withdrawals are processed within 24 hours, there is no maximum wait period on withdrawals. LPs should assess available liquidity, withdrawal queue depth, and lending market utilization before requesting large withdrawals. New deposits and swap inflows restore liquidity independently of operator action and can shorten withdrawal times. The liquidity buffer determines the target allocation between immediately available liquidity and base assets deployed to earn yield. The operator adjusts the buffer within bounds the owner sets. A higher lending allocation increases yield but reduces immediately available liquidity and may extend withdrawal timing in a lending-heavy state. Origin’s ARM Vaults operate under strict controls that safeguard LPs from unnecessary risks. The whitelist-constrained market access, crossPrice anchor, and permissionless allocate() function are examples of these safeguards. The ARM’s operations and liquidity are viewable in real time. The primary monitoring surface for LPs and curators is the ARM page on Origin Analytics , which shows current allocations, historical APY data, TVL, and lending market yields.
