Why a Polygon PoS Withdrawal Can Stall

A Polygon PoS withdrawal can look stuck because it has two stages: a wait for a checkpoint, then a claim transaction on Ethereum. That distinction matters: the first stage needs time for the bridge process to advance, while the second needs you to sign a new transaction and pay Ethereum gas.

The withdrawal starts on Polygon, where the tokens are burned, or removed from circulation on that chain. A checkpoint is a record of Polygon activity submitted to Ethereum; after it includes the withdrawal, the bridge can release the matching asset on Ethereum. The Polygon Bridge process has more steps than a direct transfer, and that fuller guide explains the broader mechanics.

Why is my Polygon withdrawal waiting at a checkpoint?

If the status says it is waiting for a checkpoint, the withdrawal has not reached the Ethereum claim step yet. Checkpoints carry Polygon transaction data to Ethereum, so a delay here is different from a wallet transaction that is still pending. The wait can vary; there is no reliable fixed time to use as a deadline.

Start by checking the Polygon transaction in your wallet or a block explorer. If it is confirmed, keep its transaction hash and check the bridge’s Transactions view for a status change. Avoid starting a second withdrawal just because the first has not moved: the original may still be progressing, and another attempt can create a separate transfer.

What should I do when the claim is ready?

When the checkpoint is recorded, the withdrawal still needs a claim on Ethereum. Open the bridge’s transaction view, select the pending withdrawal and follow the claim prompt. Switch your wallet to Ethereum and make sure it has ETH available for gas, the fee for submitting the transaction.

The claim is a separate Ethereum transaction. If you close the bridge page after starting the withdrawal, you can return later and find the pending action using the same wallet. Polygon’s support guidance says there is no time limit to complete a pending withdrawal. Once the withdrawal has been initiated on Polygon and the tokens burned, however, it cannot be cancelled or reverted.

Why is my claim transaction still pending?

A claim can stall in the wallet even after the checkpoint is ready. A low gas setting, a sudden rise in Ethereum gas prices or an earlier queued transaction can hold it up. Check the wallet’s activity first: confirm whether the claim is pending, failed or already confirmed before sending another transaction.

If the wallet shows a pending transaction, its own controls may let you speed it up or resolve a queue. Polygon support says the Portal may show a “Try Again” option if a transaction has been stuck for more than an hour. You can also search for the withdrawal’s transaction hash in the Portal and use “Confirm Exit” if that action is available.

How can I tell whether a withdrawal is truly stuck?

Match the status to the last confirmed transaction, rather than relying only on a spinner or an old browser tab. The practical checks are:

• Confirm the withdrawal transaction on Polygon.
• See whether the bridge is still waiting for a checkpoint or now asks for a claim.
• Check Ethereum wallet activity and confirm you have ETH for the claim fee.
• Use the original transaction hash when looking up a pending withdrawal.

Only sign a claim that matches your withdrawal and destination wallet. Never share a recovery phrase to get help. In most cases, the useful next step is determined by which stage is pending: wait for the checkpoint, or complete the Ethereum claim.
