What is a wallet drainer?

Updated Sep 28, 2026

Malicious code, usually on a fake website, that tricks you into signing transactions or approvals that send your assets to an attacker.

A wallet drainer is a scam kit, usually hidden on a fake website, that tricks you into signing something harmful. The usual targets are an unlimited token approval, a signature that authorises transfers, or a transaction that sends your assets directly to the attacker.

Where drainers hide

  • Fake versions of bridges, launchpads, airdrop claim pages and trading tools, often promoted in replies, DMs or sponsored search results.
  • Compromised accounts of real projects posting "mint" or "claim" links.
  • Malicious browser extensions and fake trading bots.

Protect yourself

  • Bookmark official links from the chain's documentation and use only those.
  • Never sign a transaction or message you don't understand.
  • Keep most funds in a separate wallet that never connects to new sites.
  • Be especially careful around "airdrop" and "claim" links on new chains. They're the most common drainer lure.
