Wallet drained after signing up for a 'new exchange bonus', can anything be done?
Hey everyone,
I feel so stupid right now. I saw this ad on Reddit for a new crypto exchange launching, promising some insane deposit bonuses and staking APYs if you signed up within the first 24 hours. They even had a fancy countdown timer and everything. Ngl, it looked pretty legit, lots of slick graphics. I thought, wow, this is a real opportunity.
So, I signed up, connected my MetaMask to transfer some ETH for the bonus – just a little, like 0.8 ETH, to dip my toes in. The site prompted me to approve a smart contract interaction directly, which I thought was odd for a deposit, but I figured hey, new tech, maybe it's some kind of direct integration thing for instant bonuses. And then... poof. My entire MetaMask wallet was drained. Not just the 0.8 ETH, but everything else in there too – some MATIC, a bit of BNB. Total low five figures. My heart just sank.
I've tried reaching out to their 'support' but no reply. The website is still up. I feel like such an idiot. Is there anything at all I can do? Like, was it a malicious smart contract? Can it be traced? I'm in Seattle, reported it to the local police but they just looked at me blank.

Brian, this is a classic 'approvals scam' or 'permit exploit'. When you 'approved a smart contract interaction directly,' you very likely granted the scammer unlimited spending allowance for various tokens in your wallet. This is different from a simple transfer. A transfer moves specific funds from your wallet. An approval allows *another* smart contract (the malicious one) to move tokens *from your wallet indefinitely* until that approval is revoked. This is why not just the ETH but your MATIC and BNB also disappeared – the malicious contract then executed transfers using those approved allowances.
This kind of scam is difficult to recover from because the transaction was technically authorized by you, even if under false pretenses. The funds leave your wallet directly because you gave permission for them to do so. Your best bet is to immediately revoke any remaining approvals from that malicious site. Most blockchain explorers (like Etherscan) have a feature to view and revoke token approvals directly from your wallet address. This won't get your funds back, but it secures your wallet from any further similar drains. For example, on Etherscan, you can go to your address, click on 'Token Approvals' and connect your wallet to see and revoke. This is critical. Beyond that, tracing is possible (Chainalysis does this), but actual recovery for individuals is rare. Report to the FTC, for sure.
Oh là là, Brian, this is truly a common and painful scam, I'm so sorry. What you describe, the "approve a smart contract for deposit" and then the full wallet drain, it's classic. It means you likely granted the malicious contract unlimited spending allowance for all your tokens. This is often called a 'token approval scam' or 'wallet drainer' exploit. Unfortunately, once that approval is granted and the funds are moved, they're typically gone from your control almost instantly.
Recovery in these cases is extremely difficult. The scammers will move the funds through mixing services or multiple addresses rapidly. What you *can* do, and *should* do, is use blockchain explorers like Etherscan (for ETH/BNB) and Polygonscan (for MATIC) to follow the transactions. Trace where your funds went. Note down all the addresses. Then, report everything to the FTC – they might not recover your funds, but it helps them build intelligence on these scam networks. Some services like Chainalysis or TRM Labs do this tracing professionally, but they're usually expensive and work with law enforcement, not individuals directly for recovery. Never pay anyone promising full recovery for upfront fees; those are always recovery scammers.
Man, this sucks. Happened to me too, not with an exchange bonus specifically, but a really convincing fake DeFi site. Thought I was staking some USDC, signed a transaction, and like an hour later my wallet was emptied. All gone. It's such a hollow feeling, isn't it? For me, it was small potatoes compared to yours, about 4k. Made me feel sick.
I reported it to ChainAbuse, thought maybe there was a chance, but they basically said the same thing everyone says: once you sign those approvals, it's like handing someone the keys to your house. The funds get shuffled so fast through multiple wallets, often overseas. The police aren't equipped to deal with it, sadly. Lesson learned the hardest way possible. Now, I only ever approve transactions manually with minimal amounts, and I always, always double-check the contract address if I can. Hard to do when you're caught up in the moment, though.
Ag man, I'm so sorry this happened to you, Brian. It's horrible. These scammers prey on people wanting to get ahead. My cousin fell for something similar, although it was a fake trading platform not an exchange. It's always about the promise of easy money, isn't it?
Honestly, from what I've seen with these types of scams down here in South Africa, once funds are gone via a malicious smart contract, they're gone. It's like trying to catch smoke in your hands. The decentralized nature of crypto means there's no central bank or authority to reverse transactions. Be careful now because you'll likely get messages from 'recovery agents' who claim they can get your money back. They're just another scam trying to hit you a second time. Don't fall for that please. Focus on securing your remaining digital life, change passwords, etc.
