The recovery of cross-chain deposits is a high risk process, and not all deposits can be successfully recovered. The type of currency mistakenly sent and the type of receiving address can influence difficulty, time and security risk involved.
Because of the risk involved in recovery operations, we have implemented a fee structure for attempted token recovery operations. Cross-chain deposits must have a minimum value of 0.5 BTC to be eligible for a recovery attempt, and will incur a fee of 0.1 BTC upon successful recovery.
Please note that we are unable to recover tokens from blockchains that we do not support.
