When a Polygon PoS Withdrawal Is Ready to Claim

You can claim a Polygon PoS withdrawal after validators have checkpointed the Polygon block containing your burn transaction to Ethereum. The burn starts the withdrawal; it does not send the asset to Ethereum by itself. Once the checkpoint is on Ethereum and a proof is available, you can submit the separate claim transaction that releases the asset.

The sequence is burn, checkpoint, proof, claim. For a fuller walkthrough of the transfer steps, see this guide to moving assets with Polygon Bridge. The wait is for the checkpoint, not a fixed cooling-off period that starts when you press withdraw. That distinction explains why two withdrawals made at different times can become claimable at different times.

What happens before a withdrawal is claimable?

First, the bridge burns the Polygon-side token. For a mapped token, that is the representation held on Polygon; the corresponding asset is held in the Ethereum-side bridge contract. The burn transaction records the withdrawal request on Polygon.

Next, Polygon validators submit a checkpoint to Ethereum. A checkpoint commits to a range of Polygon blocks, allowing Ethereum’s bridge contracts to verify that a particular burn was included in one of them. Until the block containing your burn is covered by a checkpoint, the bridge cannot produce the exit proof needed for the claim.

After the checkpoint is recorded, the bridge or its proof service can assemble the proof of inclusion. The claim transaction submits that proof to the Ethereum-side bridge contract. If it verifies and the transaction succeeds, the contract releases the corresponding asset to the destination address.

How do I know when I can claim?

Check the withdrawal status in the bridge interface using the burn transaction, and look for a claim or exit action. A completed burn with no claim action usually means the block has not yet been checkpointed or the proof is not ready. When the checkpoint is available, the interface can prepare the proof and let you sign the Ethereum transaction.

There is no guaranteed clock time for this step. Polygon’s proof-generation service checks whether a block has been checkpointed before generating the exit payload; its documentation treats an uncheckpointed block as not ready yet. Checkpoint submission and proof preparation take time, and Ethereum transaction fees or congestion affect how quickly the final claim confirms.

• Burn submitted: confirm the Polygon transaction succeeded and keep its transaction hash.
• Waiting: the burn is recorded, but its block is not yet covered by an Ethereum checkpoint.
• Ready to claim: the checkpoint and proof are available, so you can submit the exit on Ethereum.
• Claimed: the Ethereum transaction has confirmed and the released asset should appear at its destination.

Do I need to wait seven days?

Not for the standard Polygon PoS bridge withdrawal. That route waits for a validator checkpoint and then requires a separate Ethereum claim. The seven-day wait is associated with the Plasma withdrawal route, which uses a different exit process. Check which route the interface selected before interpreting its timer.

Claimability also does not mean the asset has already arrived. The checkpoint only makes the burn provable; the Ethereum claim still has to be sent and confirmed. Keep enough ETH in the wallet that will submit the claim to pay Ethereum gas, and check that the destination address is the one you intend to receive the released token.

In practice, watch for the claim action to become available rather than relying on an estimated duration. Once the burn’s block is checkpointed and the proof is ready, you can claim; until then, the withdrawal remains in its waiting stage.
