Arbswap is a decentralized exchange (DEX) for swapping tokens and earning yield on Arbitrum One and Arbitrum Nova. To use it, you need funds and a little ETH for fees on the network you choose.
A DEX lets you trade from your own crypto wallet, without first depositing funds into a company account. Arbitrum One and Nova are separate networks built to process Ethereum transactions. A balance on One does not automatically appear on Nova.
How Does a Swap Work?
A swap trades one token for another through a liquidity pool: tokens that other users have deposited for trading. A smart contract, which is code that carries out the trade, calculates the amount you receive. The pool’s token balances affect the price.
The Arbswap DEX fits if it has the pair you want and its final quote works for you. arbswap.app may fit better if its quoted output, destination network, and total cost meet your needs. Compare the amount you will receive, not just the headline rate.
Suppose you swap USDC for ARB on Arbitrum One. You choose the amount, review the quoted ARB, and let the contract use your USDC. Your wallet may ask for an approval first; that gives the contract permission to spend that token. You then confirm the swap and receive ARB in the same wallet.
Large trades move the price more in small pools. This is called price impact. Ethereum.org’s explanation of exchange pools notes that deeper pools tend to hold steadier prices. Check the quoted output again if you change the trade size.
What Can You Trade or Earn?
You can trade tokens in available pools, supply tokens to those pools, and use eligible pool shares in farms. The pairs depend on the network and current liquidity. ETH, ARB, USDC, and gaming tokens are examples to look for, but a token’s presence does not guarantee a useful quote.
An Arbswap token swap can also show a route between One and Nova when that route is available. Moving value between networks is called bridging. Check both the destination network and the token you will receive: the same token name can refer to different contracts.
To earn pool fees, you deposit the two tokens a pool requires. In return, you receive a liquidity provider token, or LP token, that represents your share. You can withdraw your share later. An eligible farm may offer extra token rewards for staking that LP token, sometimes with a flexible or locked term.
Those rewards are uncertain. If ARB rises against USDC, for example, the pool adjusts your share as people trade. You could withdraw less value than you would have by simply holding both tokens. This difference is called impermanent loss, and fees may not cover it.
How Do You Make a Trade, and What Will It Cost?
Start with a wallet funded on the network where you plan to trade. Arbitrum’s bridge documentation says One and Nova both use ETH to pay network fees, often called gas. Select the matching network in your wallet, connect it, then choose your input and output tokens.
Review three costs before confirming: the pool fee, gas, and price impact. For an illustrative $100 swap, a 0.2% pool fee would be $0.20; gas and the pool’s price still affect the result. The actual fee depends on the route, and gas changes with network use. Your wallet shows its gas estimate before you sign.
Set a slippage limit, which is the most the exchange rate may worsen before the trade fails. For example, a 0.5% limit allows less movement than a 1% limit. If the quote shows high price impact, reducing the trade size may help more than raising the limit.
Before signing, check the token’s contract address, the selected network, and the minimum amount you will receive. This matters especially for similarly named tokens, including the distinct forms of USDC on Arbitrum One. For a first trade, I would try a small amount and confirm it arrives before doing more.
Ask yourself: does the amount arriving on the right network justify the full cost and the risk you are taking?
