Fake bridge websites: how approval phishing scams drain your wallet
You search for a bridge to move funds across chains. A Google ad sits above the real result. The logo is right. The domain looks close enough - maybe stargate-finance.io instead of stargate.finance. You click.
The site loads a pixel-perfect clone of Stargate or Wormhole. Every button, every color matches. You connect your wallet. You select a token, choose a destination chain, and hit "Bridge." A MetaMask popup asks you to approve a contract.
That approval is the trap.
The mechanics of an approval drain
A legitimate bridge needs you to approve its smart contract so it can move your tokens. The drainer works the same way, but the contract address it asks you to approve belongs to a wallet drainer, not the real bridge. Once you sign that approval, the drainer can transfer every token you allowed - not just the amount for that transaction, but all of them if you set an unlimited approval.
Most victims never read the contract address in the approval prompt. They see the logo, the site looks right, and they click confirm. The transaction preview in MetaMask or Rabby shows a contract address, but unless you check it against Etherscan or the official bridge documentation, it means nothing to you.
The drainer can sweep your approved balance instantly, often minutes later. Sometimes they wait hours. Some victims only discover the loss when they try to make a legitimate transaction and find their tokens gone.
How to spot the fake
The weakest link is the transaction preview. Before you confirm any approval, pause. Look at the contract address. Open a new tab and pull up the real bridge's contract from its official documentation or verified block explorer page. Compare them character by character. Most wallet drainers use addresses that start or end with the same pattern as the real contract, but the middle differs.
Block explorers expose the truth. Paste the address you're approving into Etherscan, BscScan, or the relevant chain's explorer. Check the contract name. A legitimate bridge contract will have a name like "StargateToken" or "WormholeBridge." A drainer contract often has generic names like "Drainer" or "ApprovalTransfer" or nothing at all.
Bookmark the real bridge URLs yourself. Do not trust search results or links from social media. If you're using Stargate regularly, save https://stargate.finance in your browser. Every time you bridge, navigate from your bookmark. That one habit kills most phishing attempts.
The Discord fake support angle
Scammers don't just rely on ads. They seed Discord servers, Telegram groups, and Twitter replies with fake support accounts. You post about a stuck bridge transaction in the real Stargate Discord. A DMs pings you: "I'm from Stargate support. Can you try our troubleshooting link?"
The link leads to a fake site identical to the real bridge support portal. It asks you to "verify your wallet" or "reset the connection." That verification is a approval transaction. You think you're fixing a stuck transfer. You're granting access to your wallet.
Real bridge support teams never DM you first. They never ask you to connect your wallet to a third-party site. If someone DMs you with help, ignore them. Go to the official Discord server, find the support channel, and ask there.
What to do if you already approved
If you suspect you've approved a drainer, revoke the approval immediately. Use a revoke tool like Revoke.cash or Etherscan's token approval checker. Find the contract address you approved and revoke it. Every minute matters. The drainer may not have swept your funds yet - many wait for a larger batch or a specific trigger.
Never approve the second attempt. Some scammers run the same site with the same contract for weeks. Revoke, and they can't touch your tokens again.
The simple rule
Fake bridge sites exist because the model works. A user sees a familiar logo, clicks connect, signs an approval, and loses everything. They never check the contract address. They never verify the domain. They never question why someone from "support" is DMing them.
Bookmark your bridge. Verify the contract address before every approval. Never trust unsolicited help.
That sequence costs you ten seconds. Not following it can drain a wallet in ten seconds.
