Fake Bridge Websites: How to Bridge Without Getting Drained

A fake bridge website is a look-alike copy of a real cross-chain bridge that tricks you into signing a transaction or token approval that hands your funds to an attacker. To bridge without getting drained, reach the bridge only through a verified bookmark or official documentation, check the domain and contract addresses, read every wallet prompt before signing and test with a small amount first.

Bridges move tokens from one blockchain to another, for example from Ethereum to a layer-2 network. Because users often bridge when they are in a hurry, chasing a new network, an airdrop or a trade, bridge interfaces are a favorite target for phishing. This guide explains how the scam works and the routine that prevents it.

How a Fake Bridge Attack Works

Most fake bridge scams follow the same steps:

1. 1The copy. The attacker clones the front end of a popular bridge and hosts it on a domain that differs by one letter, a hyphen or a different ending.
2. 2The lure. They promote the link through paid search ads, replies under the real project's posts, fake "support" accounts or announcements that a new network or airdrop requires bridging.
3. 3The connection. You connect your wallet. The site reads your balances, so it knows which tokens are worth targeting.
4. 4The prompt. You click "bridge." Instead of calling the real bridge contract, the site asks you to approve a token for an attacker's contract, sign an off-chain permit, or send funds directly to an attacker address.
5. 5The drain. Once approved, the attacker's contract pulls your tokens. Often the site shows a fake "bridge in progress" message to buy time.

Because the interface looks identical, the domain and the wallet prompt are your only reliable clues. Our guides on wallet drainers and permit signature phishing explain the signing tricks in detail.

A Hypothetical Example

The following is an illustrative composite, not a real case. Imagine a user who wants to move stablecoins from Ethereum to a new layer-2 network to qualify for a rumored airdrop. They search for the network's bridge, click the first result, which is a paid ad, and land on a site that looks exactly like the official bridge.

They connect their wallet and enter the amount. The wallet shows an approval request for "unlimited" access to their stablecoins by a contract they have never seen. They assume it is normal for bridging and approve. Within a minute, their entire stablecoin balance is transferred out, and the site keeps showing "waiting for confirmations." By the time they realize the bridge never happened, the funds have been swapped and moved through several addresses.

The losses came from three shortcuts: using a search ad, skipping the domain check and approving an unfamiliar contract with unlimited allowance.

Warning Signs Checklist

How to Bridge Safely

Use this routine every time:

1. 1Find the official bridge from the source. Go to the destination network's official documentation and follow its link to the bridge. Our guide on how to verify a website is the official project site explains how to confirm you are on the right domain.
2. 2Bookmark it. Use the bookmark from then on. Never search for a bridge and click an ad.
3. 3Check the contract. Where the project publishes bridge contract addresses, compare them with what your wallet shows before you approve.
4. 4Limit approvals. Approve only the amount you are bridging, not unlimited, when your wallet allows it.
5. 5Send a small test. Bridge a small amount first and confirm it arrives on the destination network.
6. 6Use a separate wallet for experiments. A burner wallet with limited funds caps your loss if something goes wrong.
7. 7Revoke when done. Remove approvals you no longer need, as described in our guide to revoking token approvals.

What to Do If You Used a Fake Bridge

Act quickly:

1. 1Disconnect the site and close the tab.
2. 2Revoke approvals for any contracts you approved, using a reputable approval checker reached through a bookmark.
3. 3Move remaining assets to a brand-new wallet with a new seed phrase if you signed anything suspicious or entered your seed phrase.
4. 4Record details: the domain, transaction hashes and attacker addresses.
5. 5Report it to the real bridge project, the exchange where funds may land, and through our scam report form so others can be warned.

Bottom line

Fake bridge websites succeed because they look exactly like the real thing and catch people in a hurry. Treat the domain and the wallet prompt as the truth, not the page design. Reach bridges only through official documentation and bookmarks, approve only what you need, test with small amounts and revoke approvals afterward.
