Below are some common error messages you might see in the block explorer for your failed transactions and how to fix them

Error Messages

Explanation of what happened

Solutions

ERC20: transfer amount exceeds allowance

You have previously set a limit on how much Alpaca's smart contract can move your token, which is lower than the amount your are now trying to execute.

  • Reset allowance here:

  • It's also a good practice revoke any previously allowance on contracts you no longer plan to use in the future for security purpose.

Vault::work:: bad work factor

Debt ratio is higher than the allowed leveraged. This normally happens when you try to add collateral to your active position but the amount is not enough to bring the position value below allowed leveraged. More explanation

Another scenario would be if a user try to open large position relative to the pool's liquidity which cause his position to immediately goes below the allowed work factor (through price impact caused from opening a position.) If you are not a whale, don't worry about this one. :)

  • Increase the amount of collateral you are adding

  • Reduce your position size

Vault::work:: insufficient funds in the vault

Not enough liquidity in the deposit vault for the loan size that you requested

  • Reduce your position size

  • Wait for utilization level of the pool to reduce

Vault::work:: too small debt size

The debt size you are requesting is too small. Please refer to this for the minimum allowed debt size for each asset.

  • Increase amount of supplied asset

  • Increase leverage

Insufficient LP tokens received

Your transaction was reverted because there is a large, unfavorable price movement beyond your slippage settings before the transaction is confirmed

  • Increase slippage tolerance but make sure that it is not too high

  • Refresh page and try again

Insufficient farming tokens received

Your transaction was reverted because there is a large, unfavorable price movement beyond your slippage settings before the transaction is confirmed

  • Increase slippage tolerance but make sure that it is not too high

  • Refresh page and try again

Insufficient baseToken received

Your transaction was reverted because there is a large, unfavorable price movement beyond your slippage settings before the transaction is confirmed

  • Increase slippage tolerance but make sure that it is not too high

  • Refresh page and try again

WorkerConfig::isStable:: price too high

Asset price on PCS is 10%+ higher than the price from our external price oracle. Read more about how this protect you from bad prices

  • Wait a bit until the price on PCS and external feed converge (update every ~15 minutes)

BigNumber

One of the parameters your tx tried to pass was larger than what's accepted in the smart contract. When this error occurs, often, it's because you accidentally confirmed a duplicate tx for the same action, such as a deposit or withdrawal. Due to the funds already having moved, there's usually insufficient funds for a 2nd tx.

Another common reason to see this is if slippage for an LYF position is too high.

  • If it's an issue of repeat txs, check if your intended tx already went through. If so, you can ignore this error and continue with what you were doing.

  • If it's a slippage issue, If trying to open/close a position, you can avoid slippage by opening/closing your position without fees using this guide:

    Or you can increase your slippage settings on the top right of the app using the Gear icon.

  • If it's for another issue, refresh page and try again.

WorkerConfig::isStable:: price too low

Asset price on PCS is 10%+ lower than the price from our external price oracle. Read more about how this protect you from bad prices

  • Wait a bit until the price on PCS and external feed converge (update every ~15 minutes)

Not EOA

For security reasons, we only allow whitelisted non-EOA (Externally Owned Account) to interact with our LYF and AV contracts.

  • If you are attempting to open a farming position with a multi-sig wallet, please send your wallet address to requests@alpacafinance.org to get yours whitelisted.
