Arbswap is an Arbitrum automated market maker (AMM) for token swaps, liquidity provision, and yield farming. Choose by outcome: a completed trade, ongoing pool fees, or extra rewards on liquidity you hold. Once you have chosen, use Arbswap to exchange tokens, add to a pool, or farm a position.
Arbswap on Arbitrum: Which Path Fits?
A swap fits a one-time change in holdings, a pool fits ongoing exposure to two tokens, and a farm adds incentives to a liquidity position. These are related actions, but they leave you holding different things afterward.
- Swap — Best when you want to finish with another token. It does not fit if your aim is to earn from later trades in the pair.
- Liquidity pool — Best when you are willing to hold both tokens and earn a share of trading fees. It does not fit if you need a fixed amount of either token back.
- Yield farm — Best when you already want the pool exposure and an available farm pays additional rewards. It does not fit if the reward is too small to justify the extra transactions or any lock.
How do they connect? A swap trades against liquidity already in a pool. Adding liquidity gives you a claim on part of that pool, often represented by LP tokens; a typical farm then takes that claim as a stake and pays incentives on top of the pool’s trading fees. Check the terms of the particular farm before treating a displayed reward rate as income you can collect immediately.
The useful dividing line is how long you want to carry pair exposure. If you only need to move from one token to another, stopping after the swap avoids the deposits and later withdrawals that a pool position requires.
What Does Each Path Cost or Require?
Every path needs the right assets on the right chain and enough ETH for gas. Arbitrum’s documentation says both Arbitrum One and Arbitrum Nova use ETH for transaction fees. A common mistake is switching a wallet from Nova to One and expecting its tokens to follow; moving assets between chains is a separate transfer, after which you still need ETH where you will transact.
For a swap, compare the quoted output with the amount you expect at the current market price. Pool depth affects price impact: on a $1,000 trade, say a 1% price impact costs roughly $10 of execution value before gas and any pool fee. Slippage tolerance sets how far the quote may move before the transaction fails; raising it does not improve the price.
For liquidity, have the two assets in the proportion the pool requires. Allow for gas on any token approval, deposit, farm stake, reward claim, and eventual exit; the number of transactions depends on what you do and what is already approved. Arbswap farming rewards can change with incentives and the amount staked, so compare the likely reward over your holding period with those costs, rather than relying on an annualized rate alone.
How Do You Leave or Change a Position?
To exit a farm, first release the liquidity position under that farm’s terms, then withdraw from the pool; swap afterward if you want to finish with one token. A pool withdrawal returns your share of its current assets, which may differ from the amounts you deposited because traders have changed the pool’s balances.
That change matters more than a high reward rate. Ethereum.org calls the shortfall against simply holding the two assets impermanent loss. For example, in a conventional 50:50 constant-product pool, if one token doubles in price relative to the other, the position is about 5.7% behind holding the original tokens before fees and rewards. Pool design and price moves determine the actual result.
I would use a swap for a short-lived trade and consider a pool only when I want sustained exposure to both assets. I would add a farm only after checking that its expected rewards cover the extra costs and risks over the time I plan to stay.
