Save airdrop or tokens from hacked wallet

Claim airdrops and rescue tokens, stakes and NFTs from hacked wallets.

Antidrain claims airdrops, recovers staked tokens and sweeps NFTs out of compromised wallets on EVM chains and Solana. The claim and its transfer happen in one transaction.

Your wallet is hacked.Your assets are not gone yet.

  • A sweeper bot steals any gas you send within seconds.

  • Claim your airdrop normally and the drainer takes it.

  • Staked tokens and NFTs are still there to be taken.

  • A claim and a transfer sent apart give the bot its chance.

How a rescue works

  1. /01

    Generate a Sponsor

    Create a fresh EVM or Solana sponsor wallet that pays gas on behalf of the hacked wallet, so you never fund the compromised one.

  2. /02

    Fund the Gas

    Send a small amount of native gas to the sponsor wallet, never to the compromised wallet the sweeper bot is watching.

  3. /03

    Build the Batch

    Choose claim, transfer, unstake or sweep. On EVM chains Antidrain puts your operations into one EIP-7702 batch; on Solana the sponsor wallet pays for every transaction.

  4. /04

    Execute Atomically

    A claim and its transfer land in the same transaction, so your assets reach your safe wallet before the sweeper bot can react.

What people say

If you got drained, in the past, it's usually been "over."

Besides lost funds, unclaimed airdrops, NFT allowlist spots, and rare tokens are still sitting in a wallet you can never safely touch again.

But now, with EIP-7702 + tools like Antidrain there is a fighting chance

Frequently Asked Questions

Antidrain is a tool that helps you rescue airdrop tokens, staked tokens and NFTs from hacked or compromised crypto wallets. It works on EVM chains and on Solana, and runs entirely client-side in your browser, so your private keys never leave your device. Assets are claimed and transferred in a single transaction before sweeper bots can react: an EIP-7702 atomic batch on EVM chains, a sponsor-paid transaction on Solana.

First, do NOT send any gas or tokens to the hacked wallet, as sweeper bots will steal them instantly. Instead: 1) Go to antidrain.dev, 2) Generate a sponsor wallet and fund it with a small amount of gas, 3) Use the sponsor wallet to rescue your remaining tokens, NFTs, or unclaimed airdrops from the compromised wallet. Antidrain claims and transfers in one transaction, so the drainer bot cannot get in between.

Generate a sponsor wallet on antidrain.dev and fund it with a small amount of gas (ETH, BNB and so on). Choose 'Claim & Transfer', then enter your hacked wallet's private key, the airdrop contract address, the claim hex data, and a safe receiver address. Antidrain claims the airdrop and transfers the tokens to your safe wallet in a single atomic EIP-7702 transaction, so the sweeper bot on the hacked wallet has no time to take them. On Solana, choose 'Claim & Transfer' and paste the claim transaction from the dapp instead; the claimed tokens go to your safe wallet in the same transaction.

Antidrain uses a sponsor wallet to pay gas fees on behalf of your hacked wallet. On EVM chains it bundles your operations (claim, transfer, sweep) into one EIP-7702 transaction. On Solana the sponsor wallet pays every fee, and a claim goes in the same transaction as the transfer of what it pays out. Either way, sweeper bots and drainer scripts cannot front-run you. The hacked wallet never needs to hold any native tokens for gas.

A sweeper bot (also called a drainer bot) monitors a hacked wallet and automatically steals any incoming funds, including gas tokens. Antidrain beats sweeper bots by never sending gas to the compromised wallet. Instead, a separate sponsor wallet pays the gas, and the claim and the transfer happen in one transaction that the bot cannot get between.
