Aster exchange profile

Aster offers order-book spot trading and several perpetual trading modes. Its main perpetual interface covers crypto assets and price exposure to stocks and commodities; these derivative positions do not confer ownership of the referenced shares or physical assets. Shield uses a different liquidity and privacy model, while 1001x is a separate on-chain high-leverage product. Earn products, including USDF and asBNB, add investment and custody arrangements beyond the trading screen. Product names therefore identify materially different fees, collateral and exit rules.[1]

The OTC function negotiates perpetual block trades between identified counterparties. A deal code communicates an agreed price and size, after which signatures, margin checks and expiry determine acceptance. The documented price band is within 8% of mark price and at most twenty deals can remain pending. Executed positions become ordinary futures exposure. This facility does not establish a bank-funded cash OTC desk or an institutional fiat settlement service.[23]

The mobile guide describes a beta application downloaded through the official website, with wallet connection, network selection and signing before perpetual trading. It does not establish complete desktop feature parity, automatic transfer of local settings between devices, or a separately tested mobile withdrawal service. A browser or app session should not be confused with the lifecycle of an already accepted order.[17]

The VIP programme measures both rolling fourteen-day spot/perpetual volume and average ASTER holdings, assessed daily at 23:59 UTC. Its general maker-fee statement says zero basis points for all tiers from 2 February 2026, whereas the spot-specific page retains 0.005%. The reviewed text does not reconcile that scope conflict. The spot tariff above is the explicit product schedule; a zero spot fee should not be assumed from the general VIP statement. Image-only tier thresholds were not established in this review.[4]

Shield also displays an undated limited-time zero-fee promotion. Without a dated end point or a confirmed current execution quote, it does not establish that every Shield trade is currently free.[6]

At the 0.04% base taker rate, opening and closing unchanged US$10,000 notional would incur US$4 each, or US$8 in trading fees. This illustration excludes funding, price movement, slippage and collateral costs; different notional or contract groups change the result.[3]

Main perpetual funding transfers value between position holders: positive rates generally mean longs pay shorts, with the direction reversed for negative rates. The default interval is eight hours, but contract intervals and caps can change. The amount depends on position size, mark price and the applicable rate. A hypothetical US$10,000 marked position at positive 0.01% costs the long US$1 for that interval. Funding can reduce available margin even without closing the trade.[8]

Multi-asset mode is cross margin only. Eligible collateral is discounted rather than counted at face value: the guide gives, for example, 95% for supported BTC/ETH/BNB collateral and 80% for ASTER in the specified BNB Chain configuration. A negative USDT or USD1 settlement balance can accrue hourly interest above a separate 1,000-unit allowance. The published hourly rate is 0.000457%, introduced on 9 April 2026. Conversion rules can also sell collateral to resolve debt; a positive overall equity figure is not proof that no settlement-token borrowing exists.[9]

The main funding guide moves assets between the connected wallet and the selected trading balance. Withdrawals require the token, destination network and amount to be selected and signed. Its reference to completion within minutes is an estimate, not a uniform network settlement commitment. In USDT-settled Pro trading, non-USDT collateral can coexist with USDT debt. Repayment or collateral rebalancing may be necessary before the requested withdrawal becomes available.[11]

No single deposit minimum, withdrawal minimum or all-network withdrawal tariff was established from these guides. The relevant product and selected network determine the displayed transfer terms. The inspected crypto routes also do not establish a direct Aster bank-deposit account or a matching bank cash-out facility.[11]

Aster Chain uses proof of staked authority. In its documented Phase 1, external validators are not supported and core chain contracts and RPC components are not open source. Cross-chain deposits use three-of-four validator approval; withdrawal batches use two-of-three. The exchange is classified here as hybrid because wallet access coexists with permissioned settlement and bridge infrastructure. Privacy can hide balances and positions, with a viewer-pass mechanism, but does not remove those operating dependencies. Internal transfers are disabled when account privacy is on.[2]

USDF has a separate custody chain. Its documentation places underlying USDT with Ceffu and uses MirrorX to support hedging on Binance while custody remains at Ceffu. Settlement is described as T+1. This structure adds custodian operations, exchange solvency, hedging, funding, liquidation and USDT depeg exposure. A delta-neutral target does not make the asset a bank deposit or guarantee that a redemption can be paid immediately.[31]

The trading insurance fund is a loss-handling mechanism within the product. The inspected audit and risk disclosures do not establish a named private insurance policy with a recoverable per-customer limit or a statutory compensation entitlement.[20][30]

The 25 February 2026 terms require users to be at least eighteen and exclude people or entities located, resident or incorporated in the US, Canada, UK, China, North Korea, Russia, Ukraine, Cuba, Iran, Venezuela and Syria, alongside applicable sanctions restrictions. Aster may request identification and restrict trades or transfers. Technical wallet access does not establish legal eligibility. The terms reserve an inactivity charge without publishing an amount or trigger in the inspected passage.[27]

The privacy policy names the controller only as Aster and describes collection of wallet, transaction, device and IP information, with additional information from social login. Third-party login providers can act as separate controllers. Connecting a wallet therefore does not mean that all interface use is anonymous or that identity checks cannot arise later.[28]

The email and asset-retrieval guides do not establish a complete lost-password or lost-key recovery procedure, nor a fixed withdrawal hold after a security reset. The unsupported-token tool should not be presented as credential recovery.[14][16]

The help guide promises assistance as soon as possible but publishes no fixed response SLA or telephone dealing desk. A support message is not documented as an instruction that closes an open position.[29]

For an API 503 response indicating unknown execution, reconcile the order before retrying; repeated submission can create unwanted exposure.[25]

For 1001x specifically, the official documentation provides direct contract methods for reading positions, closing or cancelling requests, changing margin and managing exits when the interface is unavailable. This technical fallback still requires a functioning chain, correct contract and authorised signature. It is not established as a universal fallback for every Aster mode.[26]

The interface terms specify Hong Kong law and individual HKIAC arbitration in English. Disconnecting the wallet does not terminate obligations from earlier activity.[27]

The inspected privacy policy identifies its controller as Aster without establishing an exact incorporated name, registration number or registered address. No entity-level exchange or derivatives permission is asserted in this profile. A product being available on a blockchain, or a custodian being named in a separate Earn structure, does not establish an Aster licence for the user’s location.[28]

The APX conversion guide documents a manual APX-to-ASTER exchange beginning on 17 September 2025, with time-dependent conversion periods and separate handling of locked veAPX and rewards. This is a token migration record. It does not establish that an old APX balance was automatically converted, that its original ratio remains available today, or that the interface contracting entity changed.[33]

DefiLlama’s 20 October 2026 protocol snapshot reports approximately US$49.357 billion in trailing thirty-day perpetual notional and US$174.35 million in spot turnover. The corresponding twenty-four-hour values were US$1.424 billion and US$2.05 million. Perpetual notional includes leveraged exposure; it is not equivalent to cash deposited. These figures are protocol measures rather than a verified count of registered people, and Aster liquidity accessed through another interface must not be counted again as an independent venue’s additional volume.[35]

AFEE offsets eligible trading fees at the stated one-unit-to-one-USDT value; it is not margin and does not pay funding or liquidation charges. BonusUSD is nonwithdrawable collateral for the specified BNB Chain multi-asset Pro mode, although eligible trading profit can be withdrawn. Neither label should be treated as immediately withdrawable cash. The reviewed description does not establish the expiry or turnover rules of every current campaign.[10]

An API secret is shown once. If it is lost, the key must be deleted and replaced; the guide allows up to thirty keys and optional IP binding.[24]

The API reference says new keys default to access to secured routes, so a key should not be assumed read-only. The reviewed material does not establish a universal withdrawal permission switch.[25]

The API exposes trading and income history, including realised PnL, commissions and funding. User-trade queries have a maximum thousand rows and seven-day time window, with the latest seven days used by default. These are retrieval limits, not evidence of complete annual tax statements or a guaranteed CSV/PDF export.[25]

Aster’s Human versus AI Season 2 describes a testnet competition involving selected human participants and AI systems. That campaign is not evidence that the live retail account includes an AI adviser with discretion over a user’s funds. Grid and vault signing authority must be assessed on their own documented terms.[34]
