How to fix it

  1. Raise slippage a little, for example from 10% to 15% on fast-moving launches, accepting a worse price.
  2. Buy a smaller amount; larger buys move further along the curve.
  3. Raise the priority fee so your buy lands earlier in the block.
  4. Retry with a fresh quote.

If that is not it

  • On graduated coins, the trade goes to PumpSwap and fails with PumpSwap errors instead, see PumpSwap error 6004.
