What Matters: Aevo combines documented options and perpetual products with off-chain matching and on-chain settlement. The decisive questions are your margin mode, collateral treatment, full costs and exit conditions. Standard Margin is documented as the default; portfolio offsets should not be assumed. This review separates published mechanics from untested performance claims and includes a long-option expiry scenario calculator.
Editorial correction: This replaces the earlier review at its original URL. Unsupported claims about superior liquidity, stable funding, consistent high-volatility performance, reduced liquidation risk, full self-custody and a five-star rating have been removed. Original attribution and publication date are preserved.
Commercial disclosure: DN has affiliate relationships elsewhere on the site. This revision uses neutral evidence links and internal research links, without trading referral calls to action or paid placement. Documentation access is not a LIVE operational certification or confirmation that you can legally use a product.
What is documented, and what remains unverified?
The useful distinction is between a product specification and demonstrated performance. A design can support options and perps without proving that your chosen strike has a competitive quote or that a large exit can be executed at the displayed mark.
| Area | Published finding | Decision boundary and source |
|---|---|---|
| Architecture | Aevo describes off-chain matching and on-chain settlement on a custom OP-stack rollup. This is not fully on-chain order matching. | DN did not benchmark latency, resilience, decentralisation or execution quality. Primary source |
| ETH option contract | The ETH specification describes calls and puts, USDC cash settlement and 08:00 UTC expiration, with daily, weekly, monthly and quarterly expiries. | Check the actual listed instrument, expiry and settlement reference before placing an order. Documentation is not proof of current liquidity. Primary source |
| Standard margin | The documentation says accounts use Standard Margin by default and evaluate positions individually, without recognising offsetting or correlated positions. | Do not assume a hedge automatically reduces the account margin requirement. Inspect the actual mode and order preview. Primary source |
| Portfolio margin | The separate portfolio model describes scenario margin and floor margin, with 15 price/volatility scenarios. Its parameters are changeable and examples include historical initial settings. | A smaller requirement is not proof of lower economic risk. DN has not reproduced the current account risk engine or confirmed access to this mode. Primary source |
| Collateral | The collateral page states USDC settlement and lists multiple collateral assets with different value ratios. Its table includes ETH and WBTC at 90%, and weETH at 85%. It describes collateral conversion after negative USDC balances. | The page also uses future-tense rollout wording. Verify deployed assets, ratios and conversion rules in the account; documentation alone does not prove rollout completion. Primary source |
| Options fees | The page lists maker 0.03% and taker 0.05% of notional with a premium-based cap. It describes 0.015% in-the-money settlement fees, another cap and an exemption for daily options. | Confirm account and instrument fees. The worked trading-fee example contains arithmetic inconsistencies; the DN tool therefore uses explicit user-entered total fees, not copied sample totals. Primary source |
| Perpetual fees | The page lists standard maker 0.05% and taker 0.08% of notional, multiple tiers and a notice that standard fees will be reduced. | That unresolved update notice makes the actual account fee preview essential. These published figures are not a verified current executable quote. Primary source |
| Withdrawals | The withdrawal page describes different destination timings, bridge-congestion dependence and additional security checks for flagged withdrawals. | DN did not test withdrawals. A documented estimate is not a deadline guarantee or proof of an unrestricted exit. Primary source |
Margin savings are conditional, not a safety rating
The former review treated portfolio margin as universal. That was too broad. The Standard Margin document explicitly describes position-by-position assessment. The Portfolio Margin document describes a different model. A hedge that looks balanced on an expiry payoff diagram may not receive the offset you expect in the actual account.
Even when offsets apply, using the released collateral to enlarge a position can increase exposure. A lower initial requirement does not establish a lower chance of liquidation. Price, volatility, collateral value and risk parameters can move together. This review makes no claim that Aevo’s model is safer than another venue’s.
Collateral is also not simply a stable-dollar balance. An asset’s market value and the portion recognised for margin are different quantities. A haircut can change; a volatile collateral asset can fall while the trade loses money. Treat auto-conversion rules as a separate cost and asset-control question, and verify whether the documented behaviour is deployed in your account.
Check the quote, the fee basis and the exit
The options fee page uses notional rather than premium as the initial fee base, subject to a cap. Those are different units of comparison. A percentage that looks small against underlying notional can be material relative to the premium paid. Settlement and withdrawal charges also require their own checks.
Source-quality note: the page’s worked trading-fee example combines a $1,000 underlying price with percentage calculations that do not match its displayed results. For example, 0.03% of $1,000 is $0.30, not $0.45. We retain the source link and flag the inconsistency rather than treating its example as executable pricing. Confirm the current fee preview and contract units directly.
For any instrument, inspect executable bid and ask prices, size available, quote age and what happens if only part of an order fills. Mark price is not a promise of the price at which you can close. DN did not measure current depth, spreads, latency, slippage or uptime, so the old comparative winners are not retained.
For perps, include funding and both entry and exit costs. For options, distinguish a pre-expiry sale from holding to cash settlement. For a multi-leg strategy, include each leg and the risk that the legs do not fill together. The DN route-cost calculator can organise cost assumptions; it does not fetch Aevo quotes.
The DN long-option expiry model
The tool below models one fully paid long call or put held to expiry. Enter total underlying exposure in asset units, not an unexplained contract count. If a contract represents a fraction or multiple of one asset, convert contracts into underlying units first. The quoted premium must use the same per-underlying-unit convention.
Long call payoff = max(settlement reference − strike, 0) × underlying units.
Long put payoff = max(strike − settlement reference, 0) × underlying units.
Modelled P&L = payoff − premium per unit × underlying units − total assumed fees.
The input is the settlement reference used by the contract, not necessarily the last displayed spot trade. All price, premium and fee inputs must use the same quote unit. The model does not assume that one USDC always equals one US dollar.
Fictional example: a long call with strike 3,000, premium 150 per underlying unit, exposure of 2 units and total fees of 4 has a premium cost of 300. At a settlement reference of 3,300, gross payoff is 600 and modelled P&L is +296 quote units. At or below the strike, gross payoff is zero and modelled P&L is −304 under those fee assumptions. These figures are not Aevo market prices or charges.
Explore the expiry scenario below. The tool also shows five settlement references around the strike. It holds the entered fee total constant for comparison; actual settlement fees can vary by outcome. The scenario table is neither a probability distribution nor a forecast.
This is not a margin or liquidation engine. It excludes short options, spreads, perps, cross-position offsets, collateral changes, early closure, time value, volatility changes and operational failures. A single long-option payoff boundary does not cap the loss of an entire margin account.
Who should investigate further, and when should you stop?
| Research question | Potential reason to investigate | Reason to pause |
|---|---|---|
| Options exposure | You understand expiry, premium, strike and contract settlement, and need to inspect an actual listed option. | You cannot reconcile contract units, costs, payoff and access conditions. |
| Portfolio hedging | You can verify the account’s margin mode and test the provider’s current risk calculations. | You assume that a hedge automatically reduces collateral or prevents liquidation. |
| Institutional workflow | You can evaluate execution evidence, controls, entity access, collateral and exit arrangements. | You need audited reliability or service guarantees that this desk review does not establish. |
Eligibility remains unresolved in this review. We have not verified current exchange-access terms against your residence, nationality, entity or intended product. The token documentation’s legal disclaimer is not a substitute for exchange-access terms. Check the actual service terms and restrictions before connecting or funding; do not bypass geographic or identity controls. This article makes no country-approval claim.
Before depositing, verify the supported asset and network, contract permissions, collateral treatment, account mode, withdrawal mechanism and recovery route. Depositing into a contract introduces dependencies distinct from keeping assets in an ordinary wallet. Review the withdrawal screen for current conditions, not just historical documentation.
Use DN’s institutional diligence worksheet to record unresolved requirements, Decision Briefs for scoped research on other architectures and Pathfinder to organise your criteria. Those routes are research aids, not an endorsement that an alternative is available or appropriate for you.
Frequently asked questions
Does Aevo use portfolio margin by default?
The reviewed Standard Margin documentation says accounts use Standard Margin by default. Portfolio Margin is described separately. Verify your actual account mode and requirements rather than assuming hedge offsets.
Does the DN options tool calculate liquidation?
No. It calculates the expiry payoff and profit or loss of one fully paid long call or put using your inputs. It does not reproduce Aevo margin, liquidation, settlement fees or pre-expiry option pricing.
Does on-chain settlement remove custody and exit risks?
No. Funds deposited into contracts remain exposed to contract, operational, collateral and withdrawal dependencies. On-chain settlement does not guarantee immediate withdrawals or uninterrupted execution.
Methodology, limitations and change log
DN reviewed the linked public sources on 15 October 2026, including the current documentation index and its Markdown pages. We separated published design from implementation uncertainty and independently checked the simple arithmetic used in our own tool. Provider statements about throughput, security and institutional performance were not treated as DN measurements.
No live account, trade, withdrawal, API credential, portfolio-margin permission or security test was used. Current exchange-access eligibility remains unverified. The source dataset is a dated documentation snapshot, not a market feed or a recommendation list. The calculator uses local arithmetic with reader-supplied assumptions and cannot approve a trade.
Change log, 15 October 2026: corrected the default-margin assumption; removed unsupported ratings and performance claims; added source inconsistencies, collateral/exit limitations, a versioned evidence snapshot and the DN long-option expiry tool. Review due 29 October 2026. Treat the snapshot as historical after that date until reviewed again.
