FAQ

Why can't I open position on the trading pairs?

You may not be able to open position due to the following reasons:

Scenario 1: Circuit Breaker triggered due to market volatility

• 20% drop in price of token within 5 mins

Scenario 2: Circuit Breaker triggered due to imbalanced short-to-long OI ratio

• When (1) short open interest is over a set threshold AND (2) ratio of short-to-long OI is larger than a set value

• See here for details

• Note: Circuit Breaker does NOT apply when the ratio of long-to-short OI is larger than the set value

Scenario 3: Insufficient liquidity for swap

• When you try to swap pay token to collateral when opening a short position, and the FLP pool has insufficient liquidity for the token involved

Scenario 4: Insufficient liquidity for trade + user opening a long position

• When the desired position size is larger than the available liquidity for trade

Why do I see more fees than expected when using Fulcrom?

If you're accessing Fulcrom through another platform (like Onchain Wallet or a trading aggregator), that platform may charge its own additional fees on top of Fulcrom’s standard trading fees. These extra charges are set by the external platform and may not appear in Fulcrom’s app or trade history.

My trade shows a profit, but my wallet balance seems lower. Why?

Similar to the above question, this can happen if external wallet fees are deducted directly from your wallet but not reflected in the PnL shown on the interface. Always account for both Fulcrom and external platform fees.

How can I see the Trading fees that were charged?

Option 1: Fulcrom UI To view the breakdown of all fees:

1. Visit fulcrom.finance

2. Connect your wallet

3. Navigate to Trade > History

4. Find the relevant transaction and expand the details

5. In the top right of the page, click the Settings logo and check the toggle for Display PnL after fees.

Option 2: On-Chain Event Log (Advanced)

1. Search the transaction on a block explorer like CronoScan

2. In the Logs section, look for the following fee-related event keys:

   • brokerFee = Fee charged by the interface routing the transaction (e.g., On-Chain Wallet)

   • marginFee = Fulcrom’s open/close fee (0.05% of position size per leg)

   • swapFee = Applied if your margin asset was swapped during trade

   • realizedPnL = Actual profit/loss from the position

3. All values are in 30-decimal precision, so convert them by multiplying the raw number by 10^-30.

   • Example: brokerFee = 1780000000000000000000000000000 → $1.78

4. Sum these fees to match against your expected vs. actual PnL

How can I avoid extra fees?

To ensure you're only paying Fulcrom’s standard fees, consider trading directly through the official Fulcrom app. If you prefer using a different interface, be sure to review their fee policies before placing a trade.

Who do I contact for support about missing funds or unclear fees?

If the issue relates to Fulcrom’s protocol (e.g. PnL, liquidation, leverage, collateral), contact Fulcrom support on Discord. If the issue involves missing funds, unexpected fees, or non-Fulcrom UI behavior, please contact the support team of the platform you used to initiate the trade.
