Fourlong is a perpetual futures exchange built natively for Solana. Its one of the most active spot ecosystems in crypto, yet traders seeking leverage have largely had to go elsewhere. Fourlong is built to close that gap: up to 50x leverage, USDT margin, no expiry.

Fourlong $F4LONG is now live on @solana testnet.

Architecture overview:
➤ 15 perpetual markets, including SOL, BTC and ETH at up to 50x
➤ Mark prices derived from a median of external spot and perpetual venues
➤ Hourly funding to keep each contract anchored to its oracle price
➤ Isolated margin, so risk in one market never affects another
➤ Fees of 0.015% maker and 0.045% taker, with gas paid in BNB
➤ The 4LP vault, through which liquidity providers make markets across every pair and earn trading fees and funding

The testnet is now open to the public. Every connected wallet receives 10,000 test USDT, and no real funds are involved.

We welcome traders to test the platform thoroughly and share feedback ahead of mainnet.

What is a perpetual future?

A futures contract with no expiry. Post USDT as margin, take a leveraged long or short, and hold for as long as your margin supports the position.

That is the core of Fourlong $F4LONG.
