Extended is migrating from StarkEx to Starknet to build toward a more composable, trustless, and capital-efficient financial system, with unified margin at its core. StarkEx enabled fast, isolated perpetuals. But our product scope has outgrown its architecture. As we expand into unified margin, the lack of composability on StarkEx becomes a structural limitation. Unified margin, by design, requires more than just execution performance — it needs a settlement layer capable of supporting multi-asset collateral, native borrowing and lending, and shared state across applications. Starknet can provide that. This migration will enable Extended to introduce a natively integrated lending and borrowing layer. Users will be able to post any supported asset — including yield-bearing ones — as collateral, and earn yield while trading. A user depositing wstETH and incurring a negative PnL on a USDC-settled perp is, in effect, borrowing USDC — with interest flowing directly to USDC lenders. Capital efficiency becomes a structural feature of the system. Next, we’ll introduce spot markets — enabling unified margin to span perps, lending, and spot within a single cross-asset collateral engine. The result is a trading system where users manage one account, not several, and all their assets contribute to a unified margin pool — maximizing available capital and reducing fragmentation. From a user perspective, this transition will be seamless. Starknet will serve purely as the settlement layer — abstracted from the user experience. EVM users will be able to deposit and withdraw instantly across six major chains without needing to interact with Starknet directly. Native Starknet users will also be supported. But the long-term vision goes further. While many perps DEXs are now pivoting toward general-purpose chains, Extended is taking a fundamentally different approach: building an EVM-compatible network on top of Starknet, where unified margin logic is embedded directly into the base layer and exposed as an ERC-20 token accessible to all applications on the network. Margining, borrowing, and liquidation are handled by the network itself — not by individual applications. This architecture enables shared liquidity across apps, global access to margin, and unified risk management. From the user’s perspective, all activity contributes to a single global margin account that can be used across dApps. Just one composable, trustless margin system designed for scale. We’re migrating to Starknet to unlock this roadmap.
