The market has seen a clear shift in narrative, with high-volume traders increasingly prioritizing decentralized exchanges over centralized platforms, a trend largely led by Hyperliquid, which set the pace for on-chain perpetual trading. Close behind, Extended has emerged as a newer perp DEX that has climbed the rankings quickly, recording around $282M+ in daily trading volume. For this Extended review, we used the platform hands-on and reviewed its documentation to focus only on what matters to traders, including execution quality, fees, supported networks, and the overall trading experience.

Extended Overview

Extended is a decentralized perpetual futures exchange that launched in 2024 and operates on Starknet, an Ethereum Layer 2 built using ZK-STARK technology. The platform focuses on delivering fast, reliable perp trading while keeping user funds fully self-custodied through Starknet smart contracts. Trades settle on-chain, while order matching happens off-chain, allowing Extended to maintain low latency without sacrificing transparency.

While most markets focus on major crypto assets, trading is not limited to cryptocurrencies alone. Through its TradFi section, Extended also offers a selection of FX pairs, commodities, and indices contracts, allowing you to take leveraged positions across multiple market types from a single platform. For markets where maintaining a liquid public order book is difficult, Extended uses RFQ execution, allowing professional market makers to provide liquidity when an order is placed. This helps the platform support less liquid crypto and RWA contracts without keeping liquidity continuously locked in thin order books.

Fees remain straightforward at 0.00% for makers and 0.025% for takers for both spot and futures markets. All positions use USDC as collateral, and trades are gas-free for users. The protocol has surpassed $156 million in total value locked and reports more than 43,000 active users.

Security is handled through a hybrid design that combines off-chain speed with on-chain validation, supported by oracle-based pricing and an insurance fund. The core Starknet perpetual contracts have also undergone a competitive audit through Code4rena.

This overview sets the foundation. Next, we’ll break down how Extended performs in real trading conditions, covering liquidity, order execution, risk controls, and where the platform fits among other perp DEXs.

Extended Pros and Cons

Start Trading on Extended!

Extended KYC and Sign-up

Signing up on Extended is quick and straightforward. You need an EVM-compatible Web3 wallet to get started. At the moment, Extended supports MetaMask directly, along with WalletConnect for connecting other supported wallets. Once your wallet is ready, the steps to start trading on Extended are simple and easy to follow.

Step 1: Open your browser, visit the official Extended website, and click “Start Trading” to launch the Extended platform.

Step 2: Once the platform loads, click “Start Trading” again in the top-right corner to view the available wallet options.

Step 3: Select a Web3 wallet to connect with Extended.

Step 4: After selecting a wallet, a connection request will appear in your Web3 wallet. Approve the request to proceed.

Step 5: Extended will then ask for permission to send a signature request and create your account. Click “Send Request” and approve the signature in your wallet to complete account creation.

Once your wallet is connected, you can start trading on Extended right away. If you want to access vault features, you will need to switch to Extended Pro, which requires an additional approval to use Extended Vaults.

Supported Networks

Extended supports seven networks: Arbitrum, Base, BNB Chain, Ethereum, Avalanche, Polygon, and Starknet. Most of these networks are EVM-compatible, which makes an EVM-compatible wallet the most practical option for the majority of users. If you are trading on Starknet, you will need a Starknet-supported wallet such as Braavos, as EVM wallets do not work on Starknet-based accounts.

Extended Trading

When trading on Extended, you get access to both spot and perpetual markets, though its spot section is limited to only 3 assets: USDT, ETH, and wBTC. Perpetual trading remains the platform’s main focus, with more than 321+ markets and leverage of up to 100x. These markets are not limited to crypto assets only. Alongside major crypto pairs, Extended lists FX pairs, commodities, indices, and stocks under its TradFi section, allowing you to take leveraged positions across several asset classes. Fees remain consistent across regular order-book markets, set at 0.00% for makers and 0.025% for takers.

The trading interface should feel familiar if you have used centralized exchanges before. Even though everything runs fully decentralized on Starknet with self-custody and on-chain settlement, the layout remains clean and functional. You get TradingView-powered charts with access to indicators and charting tools, while the order book and trading panel sit on the right, making execution straightforward.

Leverage limits are tied directly to margin requirements, which you can view easily from the trading interface. These requirements are predefined but can adjust based on market conditions and available liquidity on Extended.

On the order side, you are not limited to basic Market and Limit orders. Extended also supports Chase, Conditional, Scaled, and TWAP orders, giving you more control over how you enter and exit positions.

For less liquid crypto and RWA markets, Extended uses RFQ execution, where liquidity is provided on demand by market makers. These markets are marked with an RFQ tag, while the order book displays indicative prices instead of publicly resting orders from other traders. Many Regular RFQ markets remain available 24/7, whereas Prime RFQ markets follow traditional market hours and are generally available 24/5. The current market status appears below the asset name, showing whether the selected contract is open or closed.

Deposit and Withdrawal Methods

On Extended, deposits and withdrawals are handled entirely through crypto networks, with no fiat options available. The platform supports seven networks: Arbitrum, Base, BNB Chain, Ethereum, Avalanche, Polygon, and Starknet. Since most of these are EVM-compatible, an EVM wallet is the most practical choice for most users, while Starknet activity requires a supported Starknet wallet.

Deposits are made directly from your connected wallet on the selected network. You simply need to ensure your wallet is funded on the same chain you plan to use.

For withdrawals, Extended offers two options: fast and slow. Fast withdrawals are available on Arbitrum and Ethereum, with a limit of $10M in a transaction. These are designed for quicker settlement when speed matters. Slow withdrawals follow the standard on-chain process and take longer, but do not carry the same speed-related conditions.

Extended Fees

Next, we look at the fee structure set up by Extended.

Trading Fees

Trading fees on Extended are fixed across both spot and perpetual markets. Makers pay 0.00%, while takers are charged 0.025% per trade. On RFQ markets, both market and limit orders pay the 0.025% taker fee, even if a limit order remains open before being filled. The market maker who accepts and fills the order pays the 0.00% maker fee. The fee structure does not change based on asset type, market conditions, or account size, keeping costs predictable for traders.

Deposit and Withdrawal Fees

Extended processes deposits and withdrawals through supported crypto networks. Transaction limits and processing times vary depending on the asset, network, transfer amount, and liquidity available through the Rhino.fi bridge. Any applicable network or transaction fee is displayed before confirmation.

Extended Products and Services

Extended offers a small set of products focused on trading and account-level returns. Here is a quick look at what is available on the platform.

Extended Trading

Extended Trading is where you spend most of your time on the platform. From a single interface, you can trade perpetual contracts across major crypto assets as well as selected FX pairs, commodities, and indices. The layout is clean and familiar, so placing trades feels intuitive even if you are coming from a centralized exchange. Execution is fast, leverage goes up to 100x, and you have access to both basic and advanced order types to manage entries, exits, and risk more precisely.

Extended Vault

Extended Vault is where trading and yield come together on the platform. You deposit USDC into the vault and receive XVS, which represents your share. These vault shares earn yield and can also be used as trading margin, so your capital stays active while you trade. Funds can be withdrawn 24 hours after deposit. The vault holds around $119M+ in TVL, with reported APRs exceeding 25%, though returns can vary with market conditions and risk.

Extended Lending

Extended Lending lets users borrow USDC against supported collateral assets, including wBTC, ETH, and USDT. This can help traders access usable margin without first selling the assets they already hold. Borrowed USDC becomes part of the account’s available balance and can be used for trading or other supported account activities. However, borrowing adds interest costs and liquidation risk. If the collateral’s value falls or the account’s margin health weakens, the position may be liquidated to repay the outstanding loan balance.

Extended RFQ

Extended uses RFQ for markets where maintaining a deep public order book would be difficult. Instead of matching your order against resting orders from other traders, the platform requests a price from professional market makers when you trade. This provides on-demand liquidity for less active crypto and RWA contracts. Regular RFQ markets use crypto-native liquidity and may trade 24/7, while Prime RFQ markets rely on TradFi partners and follow market hours. Both market and limit orders pay the taker fee.

Extended Security

Security on Extended is based on a self-custody and on-chain settlement model. Your funds and open positions are held in Starknet smart contracts, meaning the platform itself cannot access, move, or control user assets. Order matching happens off-chain for speed, but every trade, margin update, and liquidation is validated and settled on-chain through Starknet.

Risk controls include clearly defined margin requirements, partial liquidations, and an insurance fund designed to manage losses during volatile market conditions. Pricing relies on external oracles to reduce manipulation risk.

Extended’s core perpetual contracts have been audited by ChainSecurity and reviewed through a public competitive audit by Code4rena, focusing on custody, settlement, and validation logic. Since launch, no major security incidents or settlement failures have been reported.

Extended Customer Support

Customer support on Extended follows a typical DeFi model rather than a traditional helpdesk setup. There is no live chat, email ticketing system, or phone support. Most support happens through the official Discord server, where team members, moderators, and community users actively respond to questions around trading, vaults, and technical issues. Documentation also plays a major role, with detailed guides covering most platform features and common problems. Response times can vary, but Discord is generally the fastest option for time-sensitive issues.

Extended Alternatives

Extended offers a unique mix of performance and decentralized trading, but it might not be the best fit for every trader. Some users may find feature limitations, network support gaps, or interface differences compared with other DEXs or hybrid platforms. If you want options beyond Extended, there are several alternatives worth considering:

1. Lighter:  If zero-fee trading matters to you, Lighter stands out by pairing that model with a verifiable on-chain order book, something Extended does not currently offer.

2. Aster: Large order execution is handled differently on Aster, where hidden orders allow you to trade size without showing intent in the public order book.

Bottom Line

Extended sits in an interesting spot among perp DEXs. If you value low fees, fast execution, self-custody, and access to both crypto and select TradFi-style markets, the platform covers those areas well. For some traders, the Starknet setup, vault mechanics, or limited product range may feel like a good fit. For others, those same choices might feel restrictive compared to more feature-heavy platforms. That is why it helps to look at Extended in context. If you are still weighing options, browsing our top perp DEX comparison can give you a clearer sense of how Extended stacks up against other alternatives.
