Slope Wallet Swaps can fail for multiple reasons, but the primary one is due to slippage. When you perform a swap, it means you agree to a price quote. Therefore, If the price of the swap exceeds the allowed slippage set, in order to prevent you from a huge variance in value when the swap completed, it will fail. In this case, please retry it by clicking "Slippage" and then increase the price slippage. Please be aware that it means the swap will still be completed even if the token price changes more drastically during pending or confirmation. If the swap still failed after the above steps, please contact our support team
