The most common reason for withdrawal errors is insufficient TON in your wallet to cover the transaction fees.

What is needed to unstake TON?

Make sure you have at least 1.2 TON available in your wallet before unstaking. Although the transaction fee is around 0.03 TON, the pool mechanism temporarily reserves ~1.1 TON and then returns the unused amount to your wallet.

When will I receive TON during unstaking?

Another reason could be a lack of liquidity if you selected the Instant withdrawal type. In this case, Tonstakers will send you a service NFT named “Withdrawal Payout #X” and process your request after the current validation cycle ends (approximately 18 hours). You can check the status of your withdrawal requests in your Tonstakers account.
