Polygon PoS withdrawals take about three hours, plus an Ethereum claim

A withdrawal from Polygon PoS to Ethereum usually takes about three hours to reach the checkpoint stage, then needs a separate Ethereum transaction before the funds arrive. The clock can run longer if checkpoint submission or either network is delayed, and the full process is not complete until that final claim is confirmed.

Why does a Polygon withdrawal take hours?

The Polygon PoS bridge burns the bridged tokens on Polygon, then waits for validators to include that burn in a checkpoint submitted to Ethereum. The checkpoint lets Ethereum verify the withdrawal against Polygon’s recorded activity; without it, the bridge cannot release the corresponding tokens.

That wait is the main difference from a deposit, which locks tokens on Ethereum and makes the mapped asset available on Polygon after the deposit is processed. Withdrawal timing also depends on Ethereum congestion and whether the user submits the final claim promptly. For more context on how routes handle larger transfers, see this comparison of Polygon Bridge routes for treasury transfers. The route matters because different bridges can rely on different settlement steps.

What are the steps from Polygon to Ethereum?

For the standard PoS bridge, a withdrawal has three practical stages: burn the asset on Polygon, wait for the checkpoint, and claim it on Ethereum. Starting the withdrawal does not send the Ethereum-side funds immediately; it begins the burn and checkpoint process.

• Burn: Sign the withdrawal on Polygon. This uses POL for network gas and burns the bridged token there.
• Checkpoint: Wait for validators to commit the relevant Polygon activity to Ethereum. The bridge interface should show when the withdrawal is ready for the next step.
• Claim: Submit the exit transaction on Ethereum. This uses ETH for gas, and the tokens arrive after that transaction confirms.

Budget for both networks’ fees and keep access to the wallet that initiated the withdrawal. If the checkpoint has arrived but the claim is still pending, check the bridge status and the Ethereum transaction in your wallet; a low gas setting or network congestion can delay the last step.

What can make the wait longer?

Checkpoint delays, Ethereum congestion, a failed transaction, or a claim that has not been submitted can extend the total time beyond the usual estimate. The roughly three-hour figure is a planning guide for the PoS checkpoint stage, not a guaranteed end-to-end deadline.

Check which Polygon network and bridge route you used before estimating a withdrawal. Polygon zkEVM Mainnet Beta was sunset on July 3, 2026, and its former bridge withdrawal process is no longer available; eligible self-custodied funds use a separate claims process. For an ordinary Polygon PoS withdrawal, allow time for the checkpoint and keep enough ETH available to complete the claim.
