Fees

💸 Fees

PredictBase is fully decentralized and transparent — and so is the fee model. Here’s a full breakdown of fees you may encounter while using the platform.

---

🔨 Market Creation Fee

• 0.001 ETH

• Paid once when creating a new market

• Covers gas costs and admin review

• Non-refundable, even if the market is rejected or canceled

💡 This helps prevent spam or low-quality markets and ensures each submission is thoughtful and deliberate.

🧾 Betting Fee (2% Total)

Each bet includes a 2% transaction fee, which is split evenly:

Fee Type	Amount	Description
Creator Fee	1%	Paid to the market creator after the market is resolved
Protocol Fee	1%	Used to fund PredictBase development, infrastructure & audits

These fees are calculated on top of your bet amount.

Example:

• You want to bet 100 USDC

• You’ll need 102 USDC (100 USDC + 2% fee)

• If your option wins, your payout is still based on the full 100 USDC

🏛 What Are Fees Used For?

• Paying market creators to incentivize good, well-structured markets

• Supporting platform development and future improvements

• Covering infrastructure (indexing, hosting, security)

• Funding audits, bug bounties, and long-term sustainability

---

📉 No Hidden Costs

• ❌ No monthly fees

• ❌ No deposit or withdrawal fees

• ❌ No surprise slippage or commissions

You only pay:

🔁 Refunds on Canceled Markets

If a market is canceled:

• You will receive a full refund

• This includes your original stake and any paid fees

Refunds are claimable directly through the UI and handled 100% via smart contract logic.
