Extended review

Extended is a decentralised perpetual futures exchange operating on the Starknet blockchain, offering traders access to markets spanning cryptocurrencies and traditional assets with leverage up to 100x. The platform integrates directly with EVM (Ethereum Virtual Machine) compatible wallets, allowing users to trade without depositing assets on a centralised exchange or bridging between chains. Trading pairs include over 50 markets, spanning major cryptocurrencies, altcoins, and synthetic assets, providing diversity beyond typical spot-only offerings. Extended operates without KYC requirements, and users maintain self-custody of funds throughout trading, mitigating counterparty risk inherent to centralised exchanges. Fee structure shows zero maker and taker fees, a competitive stance designed to incentivise trading volume on an emerging protocol. The platform operates as a fully on-chain engine, meaning order books, matches, and settlements are recorded on Starknet rather than off-chain databases. This design prioritises transparency and reduces reliance on platform-controlled infrastructure. However, as an early-stage decentralised protocol, Extended lacks the operational maturity, liquidity depth, and user-friendly interfaces of established derivatives exchanges such as Bybit or Hyperliquid. Transaction finality depends on Starknet's layer-two confirmation times, typically several seconds to minutes. Smart contract audits and insurance coverage have not been widely publicised, creating technical and financial risk for traders unfamiliar with evaluating protocol security. Availability is global and jurisdiction-agnostic because the platform is non-custodial and blockchain-based; however, users in regulated jurisdictions such as the United States and European Union may face legal uncertainty. Supported assets currently number approximately 50, though the exact list varies with market demand and protocol development. Extended is particularly suited to traders with technical competence in EVM wallets and a tolerance for early-stage protocol risk. It directly competes with other decentralised derivatives platforms like dYdX and Hyperliquid but differentiates on leverage caps, asset variety, and Starknet's alternative layer-two architecture. Key limitations include limited liquidity compared to established centralised exchanges, no customer support or dispute resolution mechanism typical of regulated platforms, and exposure to smart contract vulnerabilities. The platform's youth and smaller user base mean fewer trading pairs may be liquid at any given time, potentially resulting in wider spreads and slippage during volatile markets. Users must understand blockchain interactions, wallet management, and the irreversibility of blockchain transactions before participating.

Extended is lightly regulated or non-custodial. No major custody breach on record. As with any platform, use strong security and only hold what you need on it.
