Completing a Polygon PoS withdrawal

A Polygon PoS withdrawal has two parts: first, the Polygon transaction burns your tokens; later, an Ethereum transaction releases them. The second part becomes available after validators include the burn in an Ethereum checkpoint, a record that confirms Polygon transactions. Allow a few hours, and keep ETH ready for the final gas fee.

Why is the withdrawal waiting?

The first transaction removes your tokens from circulation on Polygon. Validators then group Polygon transactions into a checkpoint and submit it to Ethereum. Once that checkpoint is accepted, the bridge can prove your withdrawal and release the matching tokens on Ethereum.

That wait is part of the withdrawal process, not a sign that your tokens vanished. Polygon Support says checkpoint delays can happen when Ethereum is congested. You can finish the claim later; its support guidance says there is no time limit. But once you start a withdrawal, you cannot cancel it or return the burned tokens to your Polygon wallet.

For example, if you withdraw 100 USDC, the first transaction burns the Polygon version. After the checkpoint, the final Ethereum transaction releases the corresponding USDC there. The PolygonScan transaction record can help you check that the first transaction succeeded.

How do you finish the withdrawal?

Use Polygon Portal to find the pending transfer and submit the final claim. You need access to the wallet that started the withdrawal and enough ETH on Ethereum for gas, the fee paid to process a transaction.

  1. Open Polygon Portal and connect the wallet that started the withdrawal.
  2. Open the transaction list and select the Polygon-to-Ethereum withdrawal.
  3. Wait until the status shows the checkpoint is complete and a claim action appears.
  4. Switch your wallet to Ethereum, then check that it holds enough ETH for gas.
  5. Select the claim action and confirm the Ethereum transaction in your wallet.
  6. Wait for the Ethereum transaction to confirm, then check the receiving wallet’s token balance.

If the checkpoint is complete but Portal does not show the claim, check the burn transaction on PolygonScan and reopen the transaction list. Polygon’s withdrawal tool can also complete a pending transfer when you enter its burn transaction hash. If Ethereum rejects the claim, check the wallet’s pending transactions and gas settings before trying again.

Think of the checkpoint and the claim as separate tasks: the first waits for validators, while the second needs your Ethereum signature and ETH. That is different from how Polygon Bridge transfers work across both chains; here, the deciding condition is whether the checkpoint is complete. If you need the funds sooner, plan around that wait before starting, because the withdrawal cannot be reversed.

How to Judge a Changing Swap Quote Before You Sign

Image
When a swap quote changes, compare the new output and minimum received before signing; accept only if both still suit you. A quote is an estimate based on current pool conditions, while your signed transaction executes later. On Avalanche, that gap can matter even if you spend the same amount. A quote moves when pool balances or routes change A decentralized exchange often gets prices from liquidity pools: smart contracts holding pairs of tokens that traders swap between. Each trade changes the pool’s token balances, which changes the next estimated price. A larger trade usually moves the price more in a shallow pool than in a deep one. Suppose you enter 1,000 USDC to receive WAVAX. The first estimate is 10 WAVAX, but another trader swaps against the same pool while you review. Your refreshed estimate might be 9.94 WAVAX. Those figures are examples; the actual output depends on the pool, trade size, fees, and route available at that moment. A route is the path tokens take through one ...

Token Allowlists Explained for Cross-Chain Routes

Image
A token allowlist is the set of token contracts a route accepts, and the check can differ between the two chains in one transfer. Your wallet may hold a token with a familiar name, yet a route can reject it if its contract address is not accepted. This is separate from approving a transaction. An allowlist checks the token contract on each chain A token is a smart contract that tracks balances on a blockchain. An allowlist names which token contracts a protocol or route will handle. The ticker, such as USDC, is only a label; it does not prove two tokens are the same asset. For a cross-chain transfer, the route checks the token you send on the origin chain and the asset it can deliver on the destination. A route may accept one USDC contract on Base and deliver a different USDC contract on Arbitrum. These are illustrative cases: support depends on the route’s current configuration. Compare that with a second case: your wallet holds a wrapped token, which is a version issued by another c...

How to Recover a Pending Avalanche Swap

If your Avalanche swap is pending or failed, check its C-Chain status before retrying: a pending transaction may need time or a same-nonce replacement, while a finalized failure needs diagnosis and a new transaction. The distinction matters because submitting another swap does not cancel the first one. Check whether the transaction reached the C-Chain A wallet can show a transaction as pending even when it has not reached the network. Use the transaction hash in the Avalanche C-Chain explorer to see whether it is pending, final, or absent. A final transaction has been processed; if its execution failed, it cannot be reversed or sped up. Find the transaction hash. Open the swap’s entry in your wallet and copy its hash. Search that hash in the C-Chain explorer, checking that the network is Avalanche C-Chain and the sending address is yours. Compare the wallet with the explorer. If the explorer shows the transaction as pending, it is waiting for inclusion. If it shows a final status, in...
