What the UniDexBot can do:

UniDexBot is a platform providing trading tools on Ethereum, BSC, Polygon, Avalanche, Fantom chains.
Limit orders, trailing stop, stop loss, trading strategies Cycle, Martingale averaging.
The aggregator automatically uses the dex with the best trade price among all dexes.

How to get started:

Open WebDapp and connect your wallet

2. Each user gets it a unique wallet (gas wallet), through which swaps will be executed, it is from this wallet will be paid for gas, so the gas wallet balance of native chain token (like ETH for Ethereum) must be sufficient.
The tokens for the swaps will be taken from your main wallet and the received tokens as a result of the swap will also be sent to your main wallet.

Gas wallet

To get started, you need to attach a gas wallet to the main wallet. To do this, click on the red paper clip and confirm the transaction. After a successful transaction the paperclip will change its color to green.
To deposit your gas wallet with a native token, you can either send the token directly to it or click on the plus sign and then confirm the sending transaction.

At any time you can return the balance of gas wallet to the main wallet

2.1 Fee 0.2% is charged for each completed swap. All other actions (place, delete, change order) are free.
It should be understood that in any case you will get as much token as you set in the order. The commission will be deducted at the expense of the over profit.
For example, if you set an order of 1 ETH swap to 4000 USDT, you will get at least 4000 — slippage USDT.
In most cases, your profit will be more than the one set in the order. You can use a trailing stop to increase your profit

3. To create a simple limit order, follow these steps:

1. Select the token you are going to give (from)
2. Select the token you want to receive (to)
3. Choose a volume to sell

Important: Bot does not work with native tokens (such as ETH, BNB, MATIC and others). Only with tokens that have smart contracts, instead of native tokens you can use their wrappers (WETH, WBNB, WMATIC)

You can also forcibly select Dex from the list of available tokens, but it is recommended to keep the Aggregator. It will check prices for all Dexes and choose the most profitable for your order (Wault Swap for screenshot)

4. To place a limit order, click the Limit button. This will open a settings window.

In the Main section, you can set the price or % of volatility at which you want to swap. The bottom of the window will show the target price and the amount of token received as a result of the swap.
In the Swap params section you can set swap details.

Then click the Check Approve button and confirm the approves requests if necessary. After that the Limit order button will appear, by clicking on which the limit order will be placed.
5. In the list of orders you can control the current state, as well as pause, edit, delete or give a command to put an order on the market.

When the condition in the Target price column is met (example: Buy for less than 0.51(3%)), the bot will swap tokens using your gas wallet to send the transaction.
