Liquid customers are advised to not make Ethereum deposits that have been generated from smart contracts. Deposits made from smart contracts may not be reflected in a customer's account or may be subject to delays.
If you do not know whether a transaction you are making is a smart contract transaction, please confirm with the service from which you would be sending the funds.
You may consider using a local wallet to receive the funds initially from the smart contract before sending them to your Liquid account.
