WETH or ETH: why my wrapped ether never showed up at the casino

This is a mistake I made once, and I have since seen two friends make it too. I sent WETH to a casino deposit address that was meant for ETH. The transaction confirmed, my wallet showed it gone, and the casino balance stayed at zero.

For anyone who has not run into it, WETH is wrapped ether. It is an ERC-20 token that represents ETH one to one, and many DeFi apps use it because it behaves like any other token. I had some sitting in my wallet after using a trading app, and in the wallet it looked almost identical to plain ETH. Same logo style, same amount, a slightly different label.

The casino's deposit address was an ordinary Ethereum address, so the transfer went through without any warning. The problem is on the casino side. Its system watched that address for incoming ETH and for the tokens it supported. WETH was not on the list, so nothing was credited.

Getting it back took nine days. I contacted support with the transaction hash, explained what had happened and asked whether they could recover it. They could, because they controlled the address, but it was a manual process. They charged a recovery fee and returned the WETH to my wallet. Some casinos will not do this at all, and their terms say unsupported tokens are lost.

Here is what I do differently now.

Before sending anything, I check that the asset in my wallet is native ETH on the right network. If it says WETH, I unwrap it first. Unwrapping costs a small gas fee and takes a minute.

I read the casino's cashier page for the exact list of supported tokens. Many list USDT, USDC and ETH, and nothing else.

I never send to a casino from an app or wallet I do not use often. Unfamiliar screens are where these mistakes happen.

For a first deposit at any new site, I send a small test amount and wait for it to appear before sending the rest.

When I was looking into which Ethereum casinos handle deposits clearly, Casino Crypto Rank's write-up on ETH gambling was a useful starting point, and it got me reading cashier pages more closely. Wrapped tokens are useful in DeFi. At a casino cashier, plain ETH is the one that gets credited.
