What Happens to Bridged Tokens if a Bridge Gets Hacked?

02 November 2026

If a bridge that you used to move tokens onto Polygon gets hacked, the tokens you hold on Polygon do not automatically disappear, but they can become worthless or stranded depending on how the bridge was designed and what the hackers stole. The short answer is: your bridged tokens on Polygon are representations of assets locked on another chain, and their value depends entirely on whether the bridge’s smart contracts remain solvent.

How bridged tokens work

When you move a token from Ethereum, BNB Chain, or another network to Polygon using a bridge, the bridge locks the original token in a contract on the source chain and mints a corresponding token on Polygon. That Polygon-side token - often called a “wrapped” or “bridged” version - is a claim check. It exists only because the locked assets on the other chain back it.

A hack of the bridge typically means an attacker drained those locked assets. Once the backing is gone, the Polygon-side tokens lose their 1:1 peg. They become tokens that represent nothing - or at least nothing that can be redeemed for the original asset.

What actually happens to your tokens

Your bridged tokens remain in your Polygon wallet. The blockchain itself does not reverse transactions or delete tokens. What changes is their redeemability:

• The bridge stops functioning. If the attack compromised the bridge’s smart contracts, the bridge operator or community will likely pause or shut down the bridge. You cannot bridge back to the source chain.
• The wrapped tokens trade at a discount. If the bridge is partially compromised or there are still some reserves, a secondary market may develop where the wrapped tokens trade at a fraction of their original value. This is not a recovery mechanism - it is panic pricing.
• If the bridge is fully drained, the tokens become worthless. No one can redeem them for the original asset. They are effectively spam tokens in your wallet.

Can you ever get your value back?

There are three possible recovery scenarios, none of which are guaranteed:

1. The bridge team or a third party bails out users. Some bridge operators have raised funds or used insurance to restore user funds after a hack. This is rare and depends on the project’s resources and willingness.
2. The hack is reversed on the source chain. If the attack is caught quickly and the source chain’s validators or miners agree to roll back transactions, the locked assets could be restored. This is extremely unlikely on major chains like Ethereum.
3. A token swap or migration occurs. The bridge team might issue a new token and attempt to rebuild reserves. Existing token holders might receive a pro-rata share of whatever is recovered. This is not a full recovery in most cases.

What you can do if a bridge you used gets hacked

Check if the bridge has a recovery plan

Visit the bridge’s official website or social media channels. Look for announcements about how they plan to handle the situation. Many projects will post a recovery proposal or a claim process for affected users.

Do not sell at panic prices

If your bridged tokens are still trading on decentralized exchanges, you may be tempted to sell them for a few cents on the dollar. This locks in your loss. If there is any chance of recovery, holding is the only option that preserves that chance. However, there is no guarantee recovery will happen.

Do not interact with recovery scammers

After a high-profile bridge hack, fake “recovery” sites appear. They ask you to connect your wallet and approve a transaction to “claim” your lost tokens. These will drain whatever else you have. Only follow instructions from the bridge’s verified official channels.

Accept that you may have lost the funds

This is the hardest step but the most realistic. Bridge hacks have resulted in total losses for users in many cases. The Polygon-side tokens remain visible in your wallet, but they are not worth anything if the backing is gone.

How to Reduce This Risk in the Future

• Use well-audited, battle-tested bridges. The Polygon PoS bridge and official Polygon zkEVM bridge have been operating for years and have not been exploited. Smaller third-party bridges are higher risk.
• Move only what you need for short-term use. Avoid keeping large amounts of value bridged to Polygon for long periods. The longer funds sit in a bridged state, the more time an attacker has to find a vulnerability.
• Monitor bridge security news. Follow security firms and Polygon’s official channels. If a bridge you use announces a vulnerability, withdraw immediately.
• Consider using canonical bridges. Polygon’s official bridges are maintained by the Polygon team. Third-party bridges like Multichain, Synapse, or Across have different risk profiles. Understand which you are using.

The Bottom Line

Your bridged tokens on Polygon are not erased in a hack - they stay in your wallet. But their value depends entirely on whether the bridge still holds the locked assets on the other chain. If the bridge is drained, the tokens become worthless. No amount of waiting or complaining will bring the value back unless the bridge team steps in. Treat bridge usage as a temporary convenience, not a permanent storage solution.
