How to Choose a Blackhole Pool for Your Swap

For a Blackhole swap, choose the pool that gives you the best expected output after fees and price impact. A pool is a reserve of two tokens that traders swap against; the price shifts as those reserves change. A lower fee alone does not make a pool cheaper if it is too shallow for your trade.

Blackhole runs on Avalanche and supports pools for token pairs. Some pools may be tied to a token launch, while others trade established pairs. For a fuller explanation of how a Blackhole swap prices Avalanche tokens, see our guide to the exchange mechanics and costs. For choosing a pool, start with the output estimate shown for your own amount.

How do I compare pools for the same pair?

Compare the amount you would receive, not just the displayed fee. A pool’s depth is the amount of usable liquidity near its current price. More depth usually means a trade moves the price less. Price impact is that movement caused by your trade; it grows when the trade is large relative to the available liquidity.

Check the quote with the same input amount in each pool or route the interface offers. A direct pool may charge one fee, while a route through another token can involve more than one pool and fee. The quoted output brings those effects together, though it can change before the transaction confirms.

What costs should I check before swapping?

Look at the estimated amount out, the minimum amount out, the pool fee and the network fee. The minimum amount out is the least the transaction will accept after price changes; it is set by slippage tolerance, the limit on how far execution may move from the quote. A wider tolerance can let a worse price through, while a narrow one can cause the swap to fail if the market moves.

• Amount out: Compare what you receive for the same input, including any route shown.
• Price impact: A sharp impact for a modest trade can signal thin liquidity.
• Pool fee: Check the fee for the selected pool; pairs can have different terms.
• Minimum received: Make sure the limit suits you before signing.

Gas is paid to Avalanche to process the transaction. It is separate from the pool fee and usually does not appear in the token exchange rate. For a small trade, gas can take a larger share of the total cost; for a larger one, price impact can matter more.

When should I avoid the pool with the lowest fee?

A lower-fee pool may be the worse choice when it has less liquidity at the current price. The larger your order, the more the pool’s reserves matter: a small fee saving can be outweighed by a worse execution price. Compare the final quote again just before you submit, especially if the token is new or trading is moving quickly.

For most readers, the better pool is the one with the strongest net quote for the intended trade, provided its minimum received is acceptable. Use the displayed fee and price impact to understand why the quote differs, then check that the transaction stays within your limit. That gives you a practical choice without treating the lowest fee as the lowest cost.
