How to start trading on Extended

1. Create an account

1. Extended works with EVM and Starknet wallets. When you connect a new wallet you sign twice: once to create your Extended account and signing key (stored locally in your browser), and once to register and enable trading. source ↗
2. One trading account is created automatically per wallet; you can create up to 10 trading accounts, each with its own margin. source ↗

2. Deposit collateral

1. Supported deposit assets are USDC, wBTC, ETH and USDT (EURC listed as coming soon). EVM users can deposit from Ethereum, Arbitrum, Base, Arc, Polygon, Avalanche and BNB Chain, with asset support varying by chain. source ↗
2. EVM deposits go through the Rhino.fi bridge; for USDC the stated maximum is $10M per transaction ($1M on BNB Chain) and transactions under $1M take about 2 minutes. Limits and times may vary with bridge liquidity. source ↗
3. Starknet wallet users can only deposit from Starknet, with no transaction limits. source ↗
4. All markets settle in USDC. Non-USDC collateral counts at a reduced factor: 90% for wBTC, ETH and XVS vault shares, 95% for USDT. source ↗

3. Open your first position

1. Order types for perpetuals are Market, Limit, Conditional (stop market/stop limit, triggered by mark, index or last price), TWAP, Scaled and Chase. Options include Reduce Only, Post Only, TP/SL, and GTC/IOC time-in-force. source ↗
2. Leverage is set per market, from 1x up to that market's maximum, which falls as position size grows. Changing leverage applies to both the open position and all open orders in that market. source ↗
3. Accounts use cross margin by default. For isolated margin, create a separate trading account under the same wallet; hedge mode (long and short in the same market at once) is not supported. source ↗

4. Know how liquidation works

1. Mark prices come from the oracle provider Stork and are used to decide liquidations. An account is liquidated when its margin ratio passes 100%, with warning margin calls at 66% and 80%. source ↗
2. Liquidation works on the whole trading account, not one position: XVS is sold first, then perpetual positions starting with the largest unrealised loss, in 20% steps. source ↗

5. Withdraw

1. Withdrawals go back to the same supported chains as deposits; Starknet wallet users can only withdraw to Starknet. You can withdraw only your "Available Balance for Withdrawals", which depends on your margin. source ↗
2. For USDC on Ethereum, Arbitrum, Base, Arc, Polygon and Avalanche, withdrawals under $1M take about 2 minutes and larger ones up to 4 hours (maximum $10M per transaction). source ↗

6. Common mistakes

1. If your Available Balance for Trading Perps goes negative, all non-reduce-only orders are cancelled and only position-reducing orders can be placed. source ↗
2. Unfilled GTC orders are cancelled automatically after 3 months. source ↗
3. Chase orders run in your browser tab; closing or refreshing the tab or disconnecting the wallet pauses them. source ↗

Before you trade

Perpetual futures use leverage: a small price move against you can liquidate your collateral. Start with a small amount and low leverage, and read the venue’s current fee and margin pages, which can change after this guide was checked.
