Add WETH to MetaMask
ETH in ERC-20 form. Most DEX contracts require it instead of native ETH.
Switch network first. The import button only works on the row matching the
network your wallet is currently on. If you are unsure which one you need, it is the network
you withdrew from the exchange on.

Common problems
The token imported but shows 0
The contract is right but that address holds none of it on this network. Check the transaction on the explorer link above: it will tell you which chain the funds actually landed on.
MetaMask says the token is already added
It is on the token list for this network already — scroll the Tokens tab, or turn off the “hide tokens without balance” filter in settings.
I see a token I never imported, and it looks valuable
Airdropped scam tokens are common. Do not interact with them and do not visit the site named in the token. Selling or approving them is how the wallet gets drained.
