Unfortunately, no. Blockchain transactions are irreversible, and once a withdrawal is confirmed on-chain, the funds belong to whoever controls the destination address. Sykka has no ability to reverse, freeze, or retrieve them.
We know how painful this is, and we wish we could do more.
What might still help
If the address belongs to an exchange — contact that exchange's support with the transaction hash (TXID), amount and network. Some exchanges can credit funds sent to a deposit address under their control, sometimes for a fee.
If the address belongs to someone you know — ask them to send it back.
If it's an unknown or mistyped address — the funds are almost certainly unrecoverable. Be wary of anyone who contacts you claiming they can recover them for a fee; this is a common scam that targets people in exactly this situation.
How to avoid it next time
Copy and paste the address; never type it by hand
Check the first and last few characters against the destination after pasting
Send a small test amount first when withdrawing to a new address
