Issues on the Exchange

INSUFFICIENT_OUTPUT_AMOUNT

The transaction cannot succeed due to error: PancakeRouter: INSUFFICIENT_OUTPUT_AMOUNT. This is probably an issue with one of the tokens you are swapping.

You're trying to swap tokens, but your slippage tolerance is too low or liquidity is too low.

  1. Refresh your page and try again later.

  2. Try trading a smaller amount at one time.

  3. Increase your slippage tolerance:

    1. Tap the settings icon on the liquidity page.

    2. Increase your slippage tolerance a little and try again.

4. Lastly, try inputting an amount with fewer decimal places.

INSUFFICIENT_A_AMOUNT or INSUFFICIENT_B_AMOUNT

Fail with error 'BearSwapRouter: INSUFFICIENT_A_AMOUNT' or Fail with error 'BearSwapRouter: INSUFFICIENT_B_AMOUNT'

You're trying to add/remove liquidity from a liquidity pool (LP), but there isn't enough of one of the two tokens in the pair.

Refresh your page and try again, or try again later.

Still doesn't work?

  1. Tap the settings icon on the liquidity page.

  2. Increase your slippage tolerance a little and try again.

BearSwap Router: EXPIRED

The transaction cannot succeed due to error: PancakeRouter: EXPIRED. This is probably an issue with one of the tokens you are swapping.

Try again, but confirm (sign and broadcast) the transaction as soon as you generate it.

This happened because you started making a transaction, but you didn't sign and broadcast it until it was past the deadline. That means you didn't hit "Confirm" quickly enough.

BearSwap: K

The transaction cannot succeed due to error: BearSwap: K. This is probably an issue with one of the tokens you are swapping.

Refresh the page and try again, or increase slippage tolerance via the settings icon and try again.

This probably happened because you're trying to buy or sell tokens during a big price movement. The frontend is getting outdated information (e.g. outAmount) from the smart contract, causing the swap to fail.

Issues with Syrup Pools

BEP20: burn amount exceeds balance

Fail with error 'BEP20: burn amount exceeds balance'

You don't have enough SYRUP in your wallet to unstake from the BEAR-BEAR pool.

Get at least as much SYRUP as the amount of BEAR that you’re trying to unstake.

  1. Buy SYRUP on the exchange. If you want to unstake 100 BEAR, you need at least 100 SYRUP.

  2. Try unstaking again.
