Sometimes, users would incorrectly deposit cryptocurrency - by either using the wrong deposit address or missing certain information (i.e. memo field in currencies like XRP). This causes those deposits to become “lost in transit”, and thus will not reflect on your Liquid account.
For such cases, retrieving these lost coins will require some or a significant amount of work from our technology and operations teams depending on the case, so a fee will be charged.
Liquid can attempt to retrieve these tokens, but delivery cannot be guaranteed, and a significant fee can be charged, starting from 500 USD.
However, simpler cases such as deposits missing destination tags, will incur a charge of 10% of the deposit amount or 500 USD, whichever is lower.
Currently, Liquid’s ERC20 unified MPC-based deposit wallets makes it so that today, all ERC20’s and ETH deposits share the same deposit address, thus eliminating any ERC20-based deposit problems. You can read more about this technology here.
