Aster Review 2026: The Privacy-First Perp DEX Explained

Aster is an order-book perpetual futures exchange that runs on Aster Chain, its own Layer 1, whose mainnet Aster announced on 18 March 2026. Per its docs, "privacy is the default": with Account Privacy enabled, orders are encrypted and one-time stealth addresses keep balances and open positions out of public view, and when it is off, all trader activity is published on-chain. Deposits arrive through bridge contracts on BNB Chain, Ethereum, Arbitrum, Solana and Sui. This review covers what it is, what it costs to trade, how its rewards programs work, and where the honest risk boundaries sit. For a step-by-step walkthrough of signing up and placing a first trade, see our guide to getting started with Aster.

What Aster is

Aster runs a central limit order book for perpetual futures rather than an AMM or pooled-liquidity model. It offers two separate families of perpetual contracts, split by collateral type: USDT-margined perpetuals and USD1-margined perpetuals. Alongside perpetuals, Aster also operates spot markets, so trading isn't limited to derivatives.

Account access works two ways: you can connect a Web3 wallet, or you can sign up and log in with an email address, which lowers the barrier for traders who aren't yet comfortable with self-custody wallet flows. Aster also ships a mobile app, and it supports sub-accounts, which lets a single user separate strategies, positions, or risk allocations without holding multiple full accounts.

Fees at a glance

↳ paying fees in ASTER saves a further 5%; VIP tiers exist. Verified against Aster docs · 2026-10-05

The USDT and USD1 families share the same rates: USD1 perps cover BTC, ETH and SOL at the crypto rate plus RWA pairs at the RWA rate. What changes your cost is the category — a Group B pair costs 2.5× a general crypto pair to take. For the full fee schedule — and what we could and couldn't verify about the VIP tiers — see our Aster fees page.

Points program

Aster's core rewards mechanism is a points program organized into named stages; per Aster's own documentation, the program is currently in Stage 6, called "Convergence." Unlike some rivals' programs, the Stage 6 docs are explicit about the end state: points are "Airdrop points" that accumulate toward an $ASTER airdrop share at the conclusion of the stage — an officially documented commitment, though the conversion ratio, Stage 6's share of the airdrop allocation, and end date remain unpublished. Points run on weekly epochs with a multi-part scoring formula; our Aster points explainer covers the verified mechanics and the sharp edges in their incentive design.

The ASTER token

ASTER is Aster's native token. Its clearest documented utility is paying trading fees at a 5% discount versus paying in other assets. ASTER staking on Aster Chain is live and documented (staking docs re-read 2026-10-05; the app figures below are from 2026-07-30): holders delegate ASTER to validators and earn rewards settled in weekly epochs, drawn from fixed per-epoch ASTER reward pools plus a buyback stream — Aster states 99% of daily platform fees are used to buy back ASTER for distribution to stakers. Rewards are weighted by a chosen lock period of up to 208 weeks (~4 years), and exiting a lock early carries a penalty that scales with the time remaining — the docs' formula caps it between a minimum and maximum rate whose worked examples use 2% and 60%, though both are labeled example parameter values rather than committed bounds. The docs publish no fixed APY; the staking app shows per-epoch estimates instead — on 2026-07-30 it displayed loyalty-reward APYs from 2.89% (26-week lock) to 23.13% (208-week lock) plus base APYs around 1.5–2% per validator, with roughly 456M ASTER staked network-wide. Treat those as the venue's own moving estimates, not a promised yield.

The ALP pool and Aster Earn

Separate from the copy-trading Vaults, Aster runs a liquidity pool with a token, ALP (ALP docs re-read 2026-10-05; the app observations below are from 2026-07-30). Per the docs, "ALP holders act as the market-maker counterparty for perp trades on the platform": depositors mint ALP, and the pool's earnings — trading P&L, trading fees, funding fees, liquidations, and platform fees — accrue directly into ALP's net asset value. The counterparty part cuts both ways: the docs state plainly that "ALP price can rise or fall depending on trading activity and market conditions," so when traders win against the pool, ALP holders absorb it. Mint and burn fees are dynamic — they depend on how far each asset's weight in the pool sits from its target (the docs' example: burning into an already-scarce asset costs 0.7%) — and on 2026-07-30 the app showed a 48-hour no-burn lockup after minting, which the docs do not state. On 2026-07-30 the Earn page listed ALP at roughly $13.3M TVL with no APY figure displayed, alongside two other Earn products: asBNB (a BNB liquid-staking derivative) and asUSDF (a yield-bearing version of Aster's USDF stablecoin). We don't cite yield projections for any of them — the pool's return is a claim on trading flow, not a savings rate; our earning guide covers why.

Risks

Aster is an unregulated trading venue. There is no investor-protection scheme backing funds held or traded on the platform, and standard leveraged-derivatives risk applies: perpetual futures can liquidate positions quickly against you, and leverage amplifies losses as readily as gains. Aster's docs publish seven audit reports: one each for AsterVault and AsterEarn (no auditor named on the page), two for asBNB (Salus Security and PeckShield), one for USDF (PeckShield), one for USDF and asUSDF (Halborn) and one for asCAKE (Salus Security); none is labelled as covering the perpetuals trading contracts — if an audit of the trading engine matters to your risk tolerance, factor that in before sizing positions. Read our full risk disclosure before trading.

Reported volume and data integrity

One thing to know before you read Aster's own volume or market-share figures anywhere: in early October 2025 the analytics site DefiLlama delisted Aster's perpetual-volume data, after its founder, 0xngmi, said Aster's volumes — which had reached $100 billion a day — were "almost perfectly correlated" with Binance's perpetual volumes, and that until lower-level order data was available "to verify if there's washtrading, aster perp volumes will be delisted" (reported by Unchained on 6 October 2025). The same report notes a backlash: some Aster community members questioned DefiLlama's motives, and 0xngmi replied that it had delisted Lighter and other perp DEXs before. We can't resolve that dispute, and we don't try to — we note it because it is unresolved.

To be clear about what this is and isn't: it is a dispute about reported trading volume, not a hack, a loss of user funds, or a trading halt — Aster has continued operating throughout. It's also why you won't find a "largest by volume" or similar volume-based claim about Aster anywhere on this site: those numbers are exactly the ones in question, so we don't repeat them. We keep an affiliate relationship with Aster; per our methodology that never changes what we tell you about it, including this.
