Is Extended Exchange legit and safe?

Extended is a real, operating perp dex live since 2024-12. It is non-custodial, KYC: none, and is backed by Seed: Tioga Capital, Semantic Ventures, Cherry Ventures, StarkWare, Cyber Fund, plus angels including Revolut executives and Lido co-founder Konstantin Lomashuk; Strategic round led by eToro, with Jump Crypto. We found 1 reported incident (listed below). Legit is not the same as low-risk: the coins traded on it can still go to zero.

The checklist

Custody: who holds your money

Orders are matched off-chain; trades, transfers, funding, liquidations and health checks are validated and settled on Arc with zero-knowledge proofs. The Terms state Extended does not hold your private keys and withdrawals must be signed with your account keys. Any EVM wallet works, and existing Starknet wallets still log in.

Who backs Extended

• Seed: Tioga Capital, Semantic Ventures, Cherry Ventures, StarkWare, Cyber Fund, plus angels including Revolut executives and Lido co-founder Konstantin Lomashuk — $6,500,000 (2024-04) source
• Strategic round led by eToro, with Jump Crypto — $12,500,000 (2026-07) source

Incidents

• 2025-10-11: Partial-liquidation bug caused about an hour of downtime. CEO Ruslan Fakhrutdinov said on a podcast that Extended handled peak load during the 10-11 October 2025 liquidation cascade, then hit a bug in partial liquidations that took the exchange down for about an hour. He said the team hot-fixed it, published a postmortem and compensated directly affected users. source

Real downsides

• US, UK, Canadian and Hong Kong residents are among the restricted persons, and VPN use is forbidden.
• It moved settlement from Starknet to Arc on 22 October 2026; USDT and wBTC are no longer supported.
• A partial-liquidation bug took the exchange down for about an hour after the October 2025 crash, according to its CEO.
• Most of the long-tail markets are RFQ markets filled from market-maker quotes rather than the order book.

Can you use it where you live?

Extended's Restricted Countries page bars anyone "residing in, located in, incorporated in, or with a registered office in" a restricted jurisdiction, "including without limitation: (A) Afghanistan, Canada, China (Hong Kong), Cuba, Iran, Iraq, Yemen, North Korea, Russia, Syria, Seychelles, Ukraine (Crimea, Donetsk, Kherson, Luhansk and Zaporizhzhia), Panama, the United Kingdom and the United States of America". The Terms of Use add that "circumventing these restrictions using a virtual private network ('VPN') is expressly forbidden." The EU is not named; Extended does not state it is supported. (source)

We report what the venue's own terms say. Don't use a VPN to get around restrictions; venues can freeze accounts that do.

How to use Extended without getting scammed

• Only open extended.exchange — fake lookalike sites and "support" DMs are the most common way people lose funds on any trading venue.
• Never share a seed phrase or private key. No real support agent will ask for one.
• A referral code only changes your fee and who gets a share of it. It never needs your keys.
• Treat every new memecoin as able to go to zero. A legit venue does not make the coins on it safe.
