Fees

Every adventure comes with its costs, and roaming around our park is no exception. Here's what you need to know about the fees in Tea-REX's prehistoric playground.

For Rex Wranglers (Traders)

Below are the costs Rex Wranglers must brave to navigate the jungle.

Hatching Fee (Protocol Fee)

The cost of bringing your new Rex into the world (opening a position). Every new Rex needs proper care from our handlers when they first hatch! This is a one-time fee of 0.02% of your position size.

Example:

If you hatch a Rex worth 4,000 USDC, the hatching fee would be 0.8 USDC (4,000 × 0.02%).

Daily Care Fee (Borrowing Fee)

Keeping your Rex healthy and powerful comes with a daily maintenance cost. The total borrowing fee is composed of:

• A 1.8% Jungle Reserve fee*

• The fluctuating lending APR, which changes according to the pool's utilization rate.

Example:

• Your Rex starts with 500 USDC (collateral) at 8x leverage to reach a 4,000 USDC power (borrowed amount).

• Jungle Reserve fee: 1.8% ( 0.0049% daily) / Example Lending APR: 3% (0.0082% daily) → Total: 0.0131% (0.0082% + 0.0049%)

• If you keep your Rex for 28 days, the total care fee will be 13.63 USDC 4,013.63 (4,000 × (1 + 0.0131%)^28) - 4,000 (initial power) = 13.63 USDC

Note: The actual care rate will fluctuate based on lending conditions. For more details see the Dynamic Lending Rates Page.

The 1.8% Jungle Reserve Fee will be reserved in the Earn pool contract for platform upkeep, insurance, and administrative purposes, ensuring smooth operations.

Release Fee (Exit Fee)

Ready to say goodbye? There's a small fee when you let your Rex go (close a position). When it's time to say goodbye, our handlers help release your Rex safely. This costs 0.1% of your final position size.

Example:

If your Long ETH Rex grows from 1.5 ETH to 2.1 ETH, the release fee would be 0.0021 ETH (2.1 × 0.1%)

Note: On the Tea-REX platform, you will see "Closing Costs" when you close a position. The Exit Fee is included in Closing Costs, along with swap fees and slippage discrepancy based on market conditions.

Emergency Care (Liquidation Fee)

In the unfortunate event that your Rex doesn't make it, an emergency care fee (liquidation fee) of 0.2% will be charged on the remaining position value.

Example:

If a 4,000 USDC long position drops to 1,800 USDC after X days and is liquidated, the fee would be 3.6 USDC (1,800 × 0.2%).
