Set slippage deliberately for repeat Avalanche swaps

For repeat Avalanche swaps, set slippage per token and trade size, then confirm the quoted minimum output before each swap. The tolerance defines how far the execution can move from the quote before the transaction fails; it is not a fee or a promise of a better price.

What does slippage tolerance control?

Slippage tolerance sets the minimum amount of tokens you agree to receive for the input amount. If the available output falls below that threshold before execution, the swap should revert rather than complete at a worse rate. A wider tolerance permits a larger price change and may help a trade execute, but it also leaves more room for an unfavorable fill.

That limit is separate from price impact, which comes from the trade’s size relative to available liquidity. A repeat order can have similar slippage tolerance each time and still face a different quote or price impact as pool conditions change. For the separate choice between trading a token and adding liquidity, see this guide to the Blackhole swap: trade or add liquidity.

How should I choose a setting for repeat swaps?

Use a setting that fits the token’s liquidity and the size of the order, not a single number copied across every asset. Deep pools generally absorb a given order with less price movement than thin pools; a larger order can also move the price more than a smaller one. Start with the interface’s default or a tight tolerance, and widen it only when you understand why the trade is failing.

• Compare the quoted output with the minimum output shown before signing.
• Use smaller orders when the quote changes sharply with trade size.
• Recheck the token and pool when swapping a less liquid asset.
• After execution, compare the received amount with the original quote.

Can I reuse the same slippage setting?

Reuse is convenient only when the asset, trade size and liquidity conditions are similar. Some swap interfaces retain a setting, but that does not mean the setting remains suitable for the next trade. Check the displayed tolerance and minimum output each time; don’t assume a saved value has adapted to the market.

If a swap fails, first review whether the quote moved or whether the order is large relative to the pool. Raising tolerance can allow execution through a bigger price change, but it does not solve thin liquidity or reduce price impact. If the minimum output looks materially worse than expected, reduce the order or wait for conditions to change.

What should I check before signing?

Confirm the input token, output token, amount, quoted output and minimum output in the wallet prompt. Treat a repeated swap as a new transaction: quotes can change between attempts, and the previous trade’s result does not guarantee the next one. The practical rule is to keep tolerance tight enough to limit unwanted movement while allowing for the conditions of that specific swap.
