Practice in the 3D floor, $100k virtual balance, no wallet neededFind the market, check the risk, place the trade.
Connect a supported wallet and choose your market. No account and no deposit to us. Funds stay in your wallet until you sign.
Review leverage, collateral, fees, funding, and liquidation price before submitting. Every order is simulated against the chain first, so a trade that would revert is never signed.
Track your position and settlement transparently from one terminal. Every fill is a Base transaction you can verify on Basescan.
Leveraged perpetuals can lose your entire collateral. These are the rules the contracts actually enforce.

Caps are set per pair by Gains and enforced onchain. Stock pairs are far lower than crypto. Minimum leverage is 1.1×; an order above a pair's cap is rejected before you sign.
90% of collateral
A position is liquidated once losses reach 90% of its collateral (the threshold tapers toward 75% above 25× leverage). Liquidation costs up to 10% of remaining collateral. Your liquidation price is shown in the ticket before you submit.
Borrowing fee, per block
Holding a position accrues a borrowing fee every block, sized by the pair's open interest imbalance. It is charged from your collateral while the position is open, so a position held for weeks costs materially more than a day trade.
0.03%–0.05% + spread
Gains charges a position-size fee per side (0.035% crypto, 0.03%–0.05% stocks) plus the pair spread (0.01%–0.06%). BASEBOOK adds no fee of its own — it is registered as a Gains referrer, which rebates part of that standard fee.
Two different prices
Prices shown on this page are vendor quotes (CoinGecko for crypto, Yahoo Finance for stocks) refreshed roughly every 90 seconds — indicative only. Your fill is priced by the Gains oracle network at execution, which is why the number you sign for can differ from the number you see.
USDC on Base
Positions are collateralised and settled in USDC on Base. You are trading a perpetual that tracks the asset's price, not the share, and not an asset anyone holds on your behalf. No shareholder rights, no dividends. Keys and funds stay in your wallet.
Stocks follow the US session
Stock pairs only open while the US equity session is open; crypto trades continuously. Market orders expire if not executed within 30 blocks, and a Base outage or RPC failure can delay opening or closing a position.

Every trade you open is verified on Base and linked to a real transaction. No screenshots, no edited P&L. Your BASEBOOK passport is an on-chain record anyone can check, and it is yours.
