A token swap costs more than its pool fee. To estimate the full cost, check the trade price, the fee built into it, and the separate network charge.
- The pool fee is part of the exchange rate; gas is a separate network charge.
- Price impact depends on your trade size and the pool’s available tokens.
- Slippage is a limit on price movement, not an extra fee.
What makes up the cost of an Avalanche swap?
A swap usually has three cost parts: the pool fee, price impact, and gas. A liquidity pool is a shared supply of tokens that traders swap against. Its fee is taken from each trade, often as a percentage of the amount swapped.
For an example, imagine a pool fee of 0.3% on a $1,000 trade. That equals $3, usually reflected in how many tokens the pool returns. This is an illustration, not a current rate for every pool; the fee depends on the pool you use.
Price impact is the change your trade causes in the pool’s price. A small trade in a deep pool may have little impact. The same trade in a shallow pool may return fewer tokens, even before the network charge.
Gas is the fee paid to the Avalanche network to process your transaction. It varies with network activity and the work the transaction requires. Your wallet normally shows an estimate before you approve the trade.
How do you estimate the amount you will receive?
Start with the quoted output: the number of tokens the swap says you should receive. Compare it with the market price, then account for the pool fee and price impact. The quote usually reflects both, so do not subtract them again if they are already included.
If you plan to trade through Blackhole swap, the Blackhole swap fees article can help you consider the fee side. Check the quote for your specific token pair and trade size, since pool depth affects the result.
Slippage tolerance sets how much the price may move before the swap is rejected. It is not a charge. A very low setting can make a trade fail if the price shifts; a very high setting can allow a worse price than you intended.
For instance, if a quote shows 50 tokens, a 1% slippage limit means you accept a minimum of 49.5. That figure is an example. Use the quote and limit shown for your own trade, and check the token pair carefully before approving.
What should you check before approving?
Before confirming, check the network, the token names, the estimated output, and the gas estimate. Avalanche uses different networks for different purposes; a wallet must be connected to the network where the tokens and pool exist. WalletConnect is a way to connect some wallets to apps by scanning or approving a connection request.
A common first-trade mistake is judging cost only by the quoted output. Fix that by noting the output and gas estimate before approval, then comparing them with your wallet balance afterward. A failed transaction can still use gas if it reached the network.
For a first trade, use a small amount and a clear quote. Blackhole swap is one way to make an Avalanche pool trade, but the pool’s depth and your chosen tokens determine the result. Check those details before you confirm.
