Perp DEX collateral compared: which stablecoins and assets each venue accepts as margin, what it earns and what can go wrong

Every perpetual venue asks the same first question: what do you deposit? In 2024 the answer was USDC. In October 2026 it is a menu. Hyperliquid, Paradex, dYdX and most newer order books still settle in USDC; Aster, GRVT, Velocity and Nado settle in USDT or a bridged form of it; Arcus and Lighter's Robinhood Chain instance run on Paxos's USDG. Several venues let you post ETH, BTC, liquid-staking tokens or tokenised Apple shares as margin at a discount, and a few pay interest on the balance while it backs a position.

Five things decide how collateral behaves: the settlement asset (fees, funding and PnL are paid in it, and losses in anything else are converted into it); the deposit chains and any swap on arrival; whether margin earns yield, which always means it is being lent to someone; the loan-to-value ratio and liquidation threshold applied to non-stable collateral; and whether margin is cross or isolated. This guide records what each venue's documentation says on those points, writing "not published" where it says nothing, then covers what goes wrong: StandX's DUSD wind-down, the USDe print at $0.65 on Binance, the USDH sunset on Hyperliquid and MiCA's effect on USDT in Europe. Some links are affiliate links; they do not affect which venues appear or how they are described.

The comparison: 25 venues from their own documentation

Values are from the venues' docs as of 30 October 2026; "not published" means the pages we opened do not state it. LTV figures are initial values unless marked. The liquidation lesson explains the terms.

Stablecoin-only venues: what the unit of account tells you

Fourteen of the 25 venues settle only in USDC, so the issuer question is Circle and the differences are plumbing: Hyperliquid mints USDC natively and takes CCTP transfers from Arbitrum, Ethereum, Base and Polygon; dYdX accepts Noble USDC and routes everything else through Skip Go; Paradex still deposits through the Starknet bridge or a partner such as Layerswap; Ostium never holds a deposit and locks USDC from your Arbitrum wallet per trade. Reya's rUSD is "wrapped USDC" that the docs say will simply be renamed USDC.

The USDT venues need a closer look. GRVT keeps balances in USDT and swaps incoming USDC into it through rhino.fi, so a USDC depositor quietly holds Tether exposure. Aster settles Aster Pro in USDT and charges 4% a year on a negative USDT or USD1 balance above a 1,000 USD free threshold. edgeX uses USDT on EDGE Chain but native USDC on the markets it launched on Circle's Arc in September 2026. Nado's USDT0 is the Ink version of USDT; Velocity moved from Drift's USDC to USDT at its relaunch. Arcus and Lighter's Robinhood Chain instance use USDG from Paxos. A trader who assumes "stablecoin means USDC" will be surprised by the issuer, the chain and, in Europe, the regulation.

Chain coverage has widened sharply. Lighter's universal deposit address accepts assets from twelve chains including Tron and Bitcoin and credits USDC; Nado does the same into USDT0 with a quoted price impact "typically under 0.05%"; Hyperliquid's email flow takes BTC, ETH, SOL, MON, XPL and ZEC but credits them as spot, which you must sell for USDC before trading perps. Pacifica is the strict exception: USDC on Solana only, and anything sent on another network is not credited.

Yield on margin: who pays it and where it comes from

GRVT's Earn on Equity has paid a 3.5% APY base rate on idle USDT and USDC since 11 August 2026 (4.5% with a referral), daily in USDT. The help centre says funds go into "proven on-chain protocols like Aave" and short-term credit instruments and that "users bear full principal risk arising from those protocols". Whether margin inside an open position qualifies is stated differently on the marketing page (yes) and in the help article ("idle"); we treat it as unconfirmed. Velocity is the most aggressive model: "Every deposit on Velocity is lendable" and collateral is "still lent out and still earning while the position is open". The docs are candid that a market "cannot always return every deposit on demand" and that losses beyond the insurance fund are "socialized across that market's remaining depositors". Nado says all deposits "earn automatic native yields, compounded from platform fees and lending activity", lenders receiving 80% of the optimal rate. Pacifica auto-lends idle USDC above 1,000 to traders running a shortfall against spot collateral; spot assets are "never rehypothecated". Aster pays nothing on balances, but asBNB, accepted at 95%, accrues Binance Launchpool rewards in its net asset value, while USDF's weekly yield goes to the staked asUSDF, not to USDF held as margin.

Everywhere else the answer is no or not yet: Extended's money market pays vault depositors, Hyperliquid's lending interest requires portfolio margin ($10k of equity or $5M of weighted volume), RISEx lists AutoYield as "coming soon", and Arcus states that "posting tokens earns nothing". Yield on margin always means your collateral is lent to someone; the docs, not the landing page, say who carries the loss.

Multi-asset collateral: haircuts and how liquidation changes

Posting ETH or a stock token instead of a stablecoin introduces two numbers. The LTV, or contribution factor, says how much of the asset counts as margin: Lighter credits ETH at 80%, weETH and XAUT at 70%, and the 23 tokenised equities on its Robinhood Chain instance at 50% (SPY and QQQ 70%); Hyperliquid's portfolio margin gives HYPE 0.65 and BTC 0.50; Extended counts wETH, cirBTC and its vault shares at 90%; Nado credits SPYx and QQQx at 80%; Arcus uses 50% as its worked example. The liquidation threshold is the second, higher number: 90% on ETH and 85% on weETH at Lighter, 0.5 + 0.5 × LTV (0.825 for HYPE) at Hyperliquid, a 0.90 maintenance weight at Nado, 60% in Arcus's example.

The consequence is a liquidation that can arrive from two sides. A long ETH position collateralised with ETH loses on the position and on the margin at once, so the effective leverage is higher than the slider shows; the hedged case is the only one where same-asset collateral reduces risk. Several venues model the gap as a loan: on Extended a negative USDC balance offset by wETH is a USDC borrow charged roughly every 15 minutes; on Arcus any USDG shortfall is an automatic loan at SOFR plus a spread that steepens above 80% utilisation. When the threshold is crossed the collateral is sold at a discount on top of the haircut: Lighter at 95% of index plus a 2% liquidation fee, Arcus at a per-asset liquidation factor below mark, Reya through a forced "auto-exchange" into rUSD at governance-set thresholds. Arcus and Lighter close perp positions first and sell tokens only for a remaining shortfall; that order is not universal. Caps bound the exposure: 4,000 ETH per user on Lighter, $10,000 per asset by default on Pacifica, API-published supply caps on Arcus. Jupiter and GMX are the older model, where the long collateral simply is the traded asset, with no haircut and no second liquidation path. The open-interest ranking below shows how much is riding on these engines.

What can go wrong: StandX, USDe and USDH

StandX DUSD. StandX built its exchange around its own "auto-yielding" stablecoin, which third-party profiles describe as USDT/USDC deposits hedged with short perpetuals on centralised exchanges under Ceffu custody. On 15 October 2026 the team said it would not issue a token and would wind down. Per the schedule reported by KuCoin and Bitrue: yield stopped on 15 October, perps went reduce-only on 20 October, a DUSD airdrop funded from "remaining project revenues" is claimable from 1 November to 31 December, remaining positions are closed at mark price on 15 January 2027, and "the deadline for DUSD redemptions and asset withdrawals is January 31, 2027", when StandX also removes its DUSD liquidity from PancakeSwap and Raydium. StandX says DUSD "stays fully collateralized"; we found no published proof of reserves. The lesson is not that DUSD failed but that a venue-issued collateral asset has a redemption window that ends when the venue does.

USDe on Binance, 10 October 2025. During the largest liquidation day in crypto's history, Ethena's USDe printed about $0.65 on Binance and about $0.92 on Bybit while Curve, Fluid and Uniswap stayed within 100 basis points of par. Ethena's founder attributed it to Binance's oracle pricing USDe off "its own relatively illiquid order book", and CoinDesk reported that Binance, unlike Bybit, had no direct minting and redemption relationship for arbitrage. USDe remained overcollateralised by about $66 million per independent attestors and supply fell "from $9 billion to $6 billion almost instantly" through redemptions. The damage landed on traders who had posted USDe as collateral under Binance's unified account and were liquidated against a price that existed nowhere else. Any venue that accepts a stablecoin at 99% and marks it to one thin order book carries the same exposure; Aster's docs warn that "an incorrect or stale USDF/USD price can affect the assessed collateral value".

USDH on Hyperliquid. Native Markets' USDH was the collateral of several HIP-3 deployers. On 14 May 2026 Coinbase became the USDC aligned-quote-asset deployer and acquired rights to the USDH brand as USDH is "phased out over time"; Markets by Kinetiq had its USDH markets settled at mark and was redeployed with USDC. As of 30 October 2026 the Hyperliquid API still shows the km and flx dexes with USDH as collateral token, and Native Markets says holders can redeem to USDC or fiat without fees during the migration. Hyperliquid's HIP-3 docs add the structural point: if a quote asset loses its status by validator vote, that vote "also disables perp dexs that use the asset as collateral". A collateral asset's governance is part of your position.

MiCA and USDT for EU users

Tether has not applied for e-money token authorisation under MiCA, so USDT is a non-compliant EMT in the European Economic Area. ESMA's January 2025 statement asked licensed providers to restrict such tokens by the end of Q1 2025, after which Coinbase, Crypto.com and Binance's EEA entity delisted or restricted USDT pairs; a March 2025 clarification left custody and transfers alone, and the MiCA transitional period for unauthorised providers ended on 1 July 2026. On 8 October 2026 ESMA went further with an opinion asking national regulators to ensure licensed CASPs "cease providing services related to non-MiCA-compliant stablecoins to clients in the European Union", with pre-existing exposures remediated within three months (early January 2027) and any continued service "strictly limited to activities necessary for the liquidation, conversion, withdrawal, transfer or safekeeping" of the assets.

For a European perp trader this means three things. Moving USDT through a MiCA-licensed exchange is ending, so funding a USDT-settled DEX from a regulated on-ramp needs a USDC leg and a swap. Self-custody is not addressed by the opinion, which targets service providers; depositing your own USDT to Aster, GRVT or Nado is not prohibited by it, but the exit to euros runs through venues that may no longer touch USDT. USDC-settled venues are the frictionless path, since Circle's USDC and EURC are authorised EMTs. None of this is legal advice, and several venues in the table geoblock EU countries regardless of the stablecoin; the regulation lesson and the no-KYC guide cover access.

A practical checklist

1. Read the settlement asset off the docs, not the deposit screen: USDC deposited to GRVT becomes USDT; Lighter's Robinhood instance takes USDG only.
2. For non-stable collateral, write down both numbers: the LTV you are credited and the threshold at which it is sold (Lighter ETH 80% and 90%; Hyperliquid HYPE 0.65 and 0.825).
3. Do not collateralise a long with the asset you are long unless you want the extra leverage; use isolated margin or a sub-account.
4. Treat yield on margin as a loan you are making: who borrows, can withdrawals be throttled (Velocity says yes), who absorbs a shortfall (GRVT says you do).
5. For venue-issued stablecoins (DUSD, USDF, rUSD, XVS) check the redemption path and its timeline before the amount matters. StandX gave its users 108 days.
6. Check how the venue prices a stablecoin for liquidation; one thin order book was enough on 10 October 2025.
7. In the EEA, plan the route back to fiat before choosing a USDT venue. The stablecoins lesson explains depeg mechanics and the incident timeline records what has already gone wrong.
