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.
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 0.12% of your position size.
Example:
If you hatch a Rex worth 4,000 USDC, the hatching fee would be 4.8 USDC (4,000 × 0.12%).
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.
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 0.12% 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 0.00252 ETH (2.1 × 0.12%)
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 0.25% 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 4.5 USDC (1,800 × 0.25%).
Position Type Matters!

Jungle Patrons, here’s what to expect when fueling the adventure.
Withdrawal Fee
Time to retrieve your assets from the jungle? When you decide to withdraw your funds, there’s a small fee to cover the process. This ensures a smooth and safe extraction from the park treasury.
Currently, we are not charging this fee!
Even trained Rexes need feeding. Below are the fees for each Prehistoric Strategy Vault.
We break it down into three parts:
Management Fees
Performance Fees

📘 Fee Details & Examples
Management Fees
Charged daily, based on an annualized rate
Example (1.8% annually): 1.8% ÷ 365 = 0.00493% per day If your vault value is $1,500 for 3 days, your fee is ≈ $0.22.
Performance Fees
Charged per Round, only when profits are made
Example (15% performance fee): If your vault grows from $1,000 → $1,100, that’s $100 profit. You pay 15% of that = $15, so you’re left with $1,085.
Exit Fees
Charged once (when you withdraw funds from the vault), and on the amount withdrawn
Example (0.2% exit fee): Withdrawing $1,500? You’ll pay $3 in exit fees. Final amount returned = $1,497
