Arbswap lets you swap tokens or provide liquidity on Arbitrum, if your wallet and funds are on the right network. A swap trades one token for another. Providing liquidity puts tokens into a shared pool that traders use, in return for a share of its trading fees.
Keep these points in mind:
-
Arbitrum One and Arbitrum Nova are separate networks. Check which one holds your tokens.
-
You need a little ETH on that network to pay transaction fees, called gas.
-
A pool can earn fees, but the value of your deposit can still fall.
What Is It, and Which Network Should You Use?
It is a decentralized exchange, or DEX, where trades run through code on a blockchain. You connect a wallet, which is the app that holds your tokens and approves transactions. For a normal swap, your tokens stay in your wallet until you approve the trade.
Choose the network where your funds already sit. Tokens on Arbitrum One do not appear in an Arbitrum Nova wallet balance. Arbswap liquidity pools are separate on each network too, so check the network shown beside any pair you select.
If your funds are on Ethereum, you must first move them to the chosen Arbitrum network. This move is called bridging and has its own fee. Once you have tokens and some ETH for gas, open Arbswap and check that its selected network matches your wallet.
How Do You Swap Tokens?
An Arbswap swap starts with a token pair: the token you spend and the token you receive. Say you have USDC on Arbitrum One and want ETH there. Select USDC as the input, ETH as the output, then enter the USDC amount.
-
Check both token names and their contract addresses. A contract address is the token’s unique identifier; tokens can share a name.
-
Read the quote: expected output, trading fee, price impact and minimum received. Price impact is how much your trade moves the pool’s price.
-
If asked, approve the input token. Approval lets the exchange contract spend that token; it may require a separate transaction and gas fee.
-
Review the wallet prompt, then confirm the swap. Check your wallet balance or transaction record afterward.
The exchange draws your output tokens from a liquidity pool, a shared supply of the pair. A large trade against a small pool changes its price more. If a $100 input quotes only $96 of output, I would reduce the trade or reconsider the pair before confirming.
Slippage is a price change between the quote and the completed trade. A 0.5% slippage setting means a quote of 100 output tokens can fall to about 99.5 before the transaction fails. Raising that limit may help a trade complete, but it also allows a worse price. A failed trade can still use gas.
Some routes can move tokens between One and Nova as part of a swap. Check the destination network before approving one. A token received on Nova will need ETH on Nova for your next transaction.
How Do You Add and Remove Liquidity?
You add liquidity by depositing the tokens a pool asks for, usually both sides of a pair. For example, an ETH–USDC pool might ask for $100 of ETH and $100 of USDC. Choose the pool, review its required amounts, approve the tokens if prompted, then confirm the deposit.
On Arbswap, a deposit may give you LP tokens. These represent your share of the pool, including fees it has collected. Keep track of them: removing liquidity means choosing your position, entering how much to withdraw and confirming the transaction.
Your withdrawal may contain different amounts of each token from your deposit. If ETH rises sharply, traders take ETH from the pool and add USDC. With a typical equal-value pool, $100 of each token could become roughly $283 when ETH doubles. Simply holding both would be worth $300, before pool fees. This gap is called impermanent loss.
StableSwap pools, when available for the pair you want, are designed for tokens that normally trade near the same price. They can offer smaller price changes on those trades. The risk remains if one token loses its expected value, so check the actual tokens before depositing.
What Does It Cost, and How Do You Choose?
Your cost depends on the transaction, the pool and the size of your trade. You pay gas in ETH for approvals, swaps and deposits. A swap also has a trading fee shown in its quote: at 0.2%, for example, that is 20 cents on $100. A thin pool can cost more through price impact than through its stated fee.
For liquidity, compare recent trading activity with the amount already in the pool. More trades can mean more fees to share, but a displayed reward rate is an estimate, not a promise. Also check whether rewards require a separate farm deposit or a lock that delays withdrawal.
For a first trade, I would pick the network holding my funds and start with a small amount. I would read the minimum received before confirming, then keep enough ETH in the wallet for the next transaction.
