Trading

ZEUS Exchange is a decentralized spot and perpetual exchange that supports low swap fees and low price impact trades.

Trading is supported by unique multi-asset pools that earns liquidity providers fees from market making, swap fees and leverage trading.

Adding a Wallet​

If you do not have a wallet yet, you can use Rabby or Metamask.

Connecting your Wallet​

After you have a wallet, you can connect your wallet by pressing the "Connect Wallet" button on the Trade page.

If you see the message: "Your wallet is not connected to Base", click on "Add Base" to your wallet.

RPC URLs

Since ZEUS is a decentralized exchange, querying of data and submitting of transactions is done through an RPC URL.

There may be times when the RPC URL is not as responsive as it should be, during these times you may notice data being slow to load or not loading on your page. It is also possible to hit the rate limit with the public Base RPC URL (https://sepolia.base.org).

To continue using the exchange during these times you can use a backup URL or switch the RPC URL in the network settings of your wallet and the page should load faster after.

A list of RPC URLs and their statuses can be found on Chainlist.

Sending Tokens​

While we are in the test network we need to specify faucets to request test ETН tokens.

Here is the list of faucets:

Swaps

ZEUS supports both swaps and leverage trading. For swaps, click on the "Swap" tab on the Trade page, this will open the interface to swap tokens.

For leverage trading, please see the below sections for more information.

Opening a Position​

To open a leveraged position on ZEUS Exchange, click “Long” or “Short” on the Trade page.

A Long position earns profit if the token price goes up and incurs a loss if the price goes down.

A Short position earns profit if the token price goes down and incurs a loss if the price goes up.

After selecting your side, specify the amount you wish to trade and the leverage you want to use.

Below the swap box, you will see the Exit Price — the estimated price used to calculate your PnL if you were to immediately close the position. This value updates dynamically with market movement.

When opening a position, several fees may apply depending on the trade parameters:

• Margin fee: 0.4% of the total position size (charged once at opening).

• Swap fee:

• 0.25% for token ↔ token conversions,

• 0.01% for stable ↔ stable swaps.

This fee applies when the purchase token differs from the collateral or index token.

• Dynamic Tax: An additional dynamic fee (up to 0.60% for tokens / 0.05% for stables) may apply if the swap causes an imbalance in the liquidity pool.

• Funding (borrow) fee: 0.01% per hour on the position size. This fee accrues hourly while the position is open and is deducted upon closing or liquidation.

Because all trading operations are executed on smart contracts, funds remain in the user’s wallet until the transaction confirming position opening is processed on-chain.

Managing Positions​

After opening a trade, your active positions are displayed in the Positions list.

By clicking “Edit”, you can deposit or withdraw collateral to adjust leverage and improve your liquidation price.

Depositing or withdrawing collateral may trigger a swap (0.25% or 0.01%) and, if it negatively affects pool balance, a Dynamic Tax (up to 0.60% / 0.05%).

No additional “deposit fee” is charged — all conversions use the same swap logic as regular trades.

Closing a Position

You can close a position partially or fully by clicking the “Close” button.

For Long positions, profits are paid in the asset you traded (e.g., if you long ETH, you receive ETH).

For Short positions, profits are paid in the stablecoin used to open the position (e.g., USDC).

You can change the payout asset in the “Receive” option within the Close Position menu — if a conversion is required, the standard Swap fee (0.25% / 0.01%) and potential Dynamic Tax will apply.

Upon closing, any accumulated Funding fees (0.01% per hour) are automatically deducted.

No additional “closing fee” applies.

Stop-Loss / Take-Profit Orders

The functionality with limit orders is currently under development and will be integrated into the exchange in the future.

Liquidations​

If a trader’s position drops below the maintenance margin threshold, it is automatically liquidated to prevent losses to the pool.

Pricing​

There is no price impact for trades on Zeus Exchange, so you can execute large trades exactly at the mark price. During times of high volatility there may be a spread from the Chainlink price to the median price of reference exchanges.

The mark prices are displayed next to the market name, long positions will be opened at the higher price and closed at the lower price while short positions will be opened at the lower price and closed at the higher price.

The chart will indicate the average of the two mark prices.

Fees

The cost of opening a leveraged position on ZEUS Exchange consists of several components that depend on the type of operation being performed.

When opening a position, a margin fee of 0.4% is charged on the total position size.

If a token conversion is required — for example, when the purchase token differs from the collateral or index token — a swap fee applies: 0.25% for token-to-token trades and 0.01% for stable-to-stable swaps.

In some cases, when a trade increases the imbalance of the liquidity pool, a Dynamic Tax may apply — up to 0.60% for token operations and up to 0.05% for stablecoin operations. This additional fee helps maintain pool balance and overall stability of the protocol.

A Funding (Borrow) Fee of 0.01% per hour on the position size is charged while the position remains open. The fee accrues continuously and is deducted automatically when the position is closed or liquidated.

An Execution Fee of 0.00018 ETH is charged to compensate the network keeper for processing transactions on-chain.

If a position is liquidated, a fixed Liquidation Fee of $5 is charged and paid to the liquidator.

No separate “closing fee” or “deposit fee” is applied. If the user adds or withdraws collateral that requires token conversion, the same swap logic applies (0.25% / 0.01% plus possible Dynamic Tax).

All fees are displayed transparently in the interface before confirming a transaction.

Network Fee​

Each operation on ZEUS Exchange requires two blockchain transactions:

1. The user submits a transaction to open, close, deposit, or withdraw collateral.

2. The network keeper observes the blockchain for this request and executes it.

The cost of the keeper’s execution is covered by the Execution Fee (0.00018 ETH) mentioned above.

In addition, users pay the standard gas fee of the underlying blockchain network (Base L2) when submitting their own transactions.

Gas fees are not retained by the protocol — they go directly to the blockchain validators.
