Everyone can create liquidity pools by depositing liquidity on Exchange.
However, the following tokens are currently NOT supported:
Fee-on-transfer tokens
Rebase tokens
For these token, please do NOT add liquidity on Exchange. Your assets may stuck in the liquidity position.
PlaxSwap is a DeFi application such that it interacts with the wallet to complete on-chain transactions for swapping, creating LPs, staking in farms and pools, etc.
Gas Fees
As such, the first thing is to make sure you have enough MATIC to pay for the gas fee of the on-chain transactions. Typically, gas fee fluctuates depending on the number of transactions in the queue, if there are more transactions, a higher gas fee may be required to push through the transaction. On Polygon Chain, the gas fee typically ranges from cents to a dollar USD in MATIC. Learn more about .
Transaction Fees
If your swapping action still doesn't go through and it is displaying an error for you to revise the slippage -- you may want to check if the tokens you are trying to swap has any fees and restrictions on transactions.
It is not uncommon for tokens on Polygon Chain to include a transaction fee in their contracts, usually these fees could be used for burning, funding a treasury of a fair launch project -- for example, this for sending to a burn address, such that more transactions would mean more burning, accruing value to APX token holders.
With the transaction fee, whether it is inclusive (a portion of the swap amount is sent elsewhere than your address so the output is less than expected for the estimated input) or exclusive (requiring an additional transfer from your address to send extra tokens so the input is more than expected for the estimated output), it affects the input and output amount that you agree for signing the transaction. In many cases, the transaction cannot meet the input and output requirements because of the tax.
Swapping with Transaction Fees
Before you swap any tokens, make sure you have visited their website to understand if they have a transaction fee mechanism (or tax as many projects put it). If there is, make sure you set a slippage that is sufficient to accommodate the transaction fee -- e.g. if there is a transaction fee of 5%, your slippage will have to be set at at least 5% plus the normal trading slippage depending on your trading amount and the token's liquidity, say 5.5%-6%.
In some extreme cases including some scams, some tokens even have a block on most or all transfers on chain, or only allowing certain addresses to sell, in such case it is impossible to swap the token successfully. Do learn about the token you are trying to swap and be aware of any fees and restrictions!
In Exchange, when you are providing liquidity, you can choose between several different trading fees (0.01%, 0.05%, 0.25%, and 1%) for the same token pair.
For example, for PLAX-MATIC, there might be a 0.25% pair, which means a 0.25% trading fee is in place for every trade. However, some liquidity providers might choose to provide liquidity to a PLAX-MATIC trading pair with a 0.05% fee rate, offers a better quote and attract more trading volume.
There is no “correct” answer for which trading fee configuration to choose. It depends on the tokens within the trading pair. Usually, volatile tokens should have a higher trading fee to better compensate for the impermanent loss brought by the volatility. On the other hand, tokens like stable coins have smaller price movements and lower impermanent losses, therefore their trading fee should be lower.
When selecting a token pair, the “Add Liquidity” interface will automatically choose the most popular fee tier for you.
In Exchange, underlying assets in a liquidity position will not always have an equal value in USD. It will depend on the price range settings of a position and the current price of the pair.
In fact. If your position goes out of range, all tokens will be converted to one single asset. Plus, you can provide liquidity to a price range that does not cover the current price and deposit one single asset only. Continue reading to learn more ⬇️
You will not earn any trading fee rewards if the current price goes out of the price range defined in your position.
On top of that, all tokens will be converted to one single asset depending on the direction of the price condition.
For example, if a position of PLAX/USDT is configured with a price range of 3 USDT per PLAX to 5 USDT per PLAX. And all assets in the position will be converted to USDT if the PLAX price is higher or equal to 5 USDT per PLAX, and vice versa.
Please not that if the price moves back in the range, you will start receiving trading fee rewards again. No additional actions are required.
Providing liquidity to a smaller price range will help concentrate your liquidity to a spesific price range, boosting your relative shares again the total liquidity within the price range, potentially earning more trading fee rewards.
However, please bear in mind that only active liquidity positions will earn trading fee rewards from trades. This means you will only earn rewards when the current trading price is within the price range defined in the liquidity position.
Automatic position managing feature is coming soon to PlaxSwap with one-click liquidity depositing (Zap!). Stay tuned for more detail.

In Exchange, LP fee reward APR could vary between liquidity positions. It is based on the following factors:
Trading volume - more volume generates more fee rewards
Liquidity pair fee tier - higher fee tier generates more fee rewards from individual trades
The number of tokens deposited - more token in the position translates to a larger relative share against the total active liquidity, which gets more trading fee rewards from trades
The selected price range - smaller price range allows a higher concentration for the same amount of token deposited, which translates to a larger relative share against the total active liquidity, and gets more trading fee rewards from trades
The amount of liquidity currently active - if there are more users who deposit and concentrate their liquidity with the same range as you, you will earn less trading fee due to a smaller relative share against the total
Whether the liquidity position is active - only active liquidity positions will earn trading fee rewards
