Question 1

What is a perpetual future?

Accepted Answer

A perpetual future tracks the spot price of an asset without an expiry date. Traders post collateral to control a larger notional position and pay or receive a periodic funding fee that keeps the perpetual price aligned with spot.

Question 2

Why trade SIGN on VOOI Ultra?

Accepted Answer

VOOI Ultra routes SIGN orders across supported venues (Hyperliquid, Lighter, Aster, Extended, Binance, trade.xyz, and Kinetiq) from a single non-custodial interface — whether it's trading app or trading via CLI/MCP/API. You see every venue's depth and fees side by side to choose the best execution at any moment.

Question 3

How is the funding rate set?

Accepted Answer

Each venue computes its own SIGN funding rate from the gap between the perpetual price and the spot index. Positive rates mean longs pay shorts; negative rates flip the direction. The funding interval differs per venue and is shown on each venue card above.

Question 4

Can I arbitrage SIGN funding rates?

Accepted Answer

Use Funding Arbitrage to spot delta-neutral spreads across two supported venues. Farm the difference per venue and execute low-risk trading strategy via VOOI with historical backtests and one-click funding rate arbitrage strategy setup.
