The migration to Starknet enables full EVM wallet compatibility, meaning users can connect with familiar wallets like MetaMask without needing Starknet-specific wallets. Starknet also offers more flexibility for smart contract development and benefits from ongoing ecosystem growth and improvements in Cairo language tooling.
Extended offers perpetual contracts on traditional finance assets including EUR/USD forex, gold (XAU), S&P 500 index, and oil. These markets allow crypto traders to gain exposure to traditional assets 24/7 with up to 100x leverage, without leaving the DeFi ecosystem.
Yes, Extended was formerly known as X10. The platform rebranded when it migrated from StarkEx to Starknet mainnet in August 2025. The rebrand coincided with several major upgrades including EVM wallet compatibility and expanded market offerings. If you had an X10 account, your data and balances carried over to Extended automatically.
Extended offers up to 100x leverage on its perpetual contracts, one of the highest among perp DEXes. This applies to both crypto markets and traditional finance assets like gold and forex. Higher leverage allows larger positions with less capital, but also increases liquidation risk. Traders should use proper risk management and start with lower leverage until they are comfortable with the platform.
After migrating to Starknet, Extended now supports full EVM wallet compatibility. You can connect using MetaMask, WalletConnect, or any standard EVM wallet without needing a Starknet-specific wallet like Argent or Braavos. Simply visit the Extended app, click connect wallet, and approve the connection from your preferred wallet. This makes onboarding much easier than other Starknet DEXes.
