Extended is a decentralized perpetual exchange deployed on Arbitrum that launched in mid-2024. The platform targets active crypto traders looking for high-leverage futures trading with a straightforward interface and competitive fee structure.

The main draw of Extended is its referral and points program. The platform offers a 20% point bonus to referred users, among the higher incentive rates in the DeFi derivatives space. Most competing protocols in this category offer 10% referral bonuses, making Extended's program a meaningful differentiator for traders who intend to bring others onto the platform or who are themselves willing to use a referral link for the bonus. These points are expected to carry future value through a potential token rewards mechanism.

On the trading side, Extended supports up to 100x leverage across roughly 25 perpetual pairs, covering the major crypto markets. The fee structure is 0.02% for makers and 0.05% for takers, which is consistent with mid-tier competitors. Cross-margin support means collateral is shared across all open positions, improving capital efficiency compared to isolated-margin-only venues.

Execution is handled on Arbitrum, benefiting from the L2's low gas fees and fast block times. The trading interface is clean and straightforward, a practical consideration for traders migrating from centralized exchanges who find some DeFi UIs cumbersome.

The main concern with Extended is the absence of published security audits. For a protocol holding user funds and processing leveraged positions, unaudited smart contracts are a real risk. Traders should factor this into their risk tolerance, particularly when considering large position sizes.

Liquidity is also a work in progress. As a newer protocol, the depth of the order book or liquidity pool is smaller than established protocols like dYdX, Hyperliquid, or GMX, which can result in higher slippage on large trades.

The 20% referral bonus is the main draw here. The missing audit is the main concern. Weigh accordingly.
