Know what you're signing, and clean up what you signed before.

• Wallet health

  One 0 to 100 score for how exposed a wallet is: open approvals, risky tokens, address-poisoning traps, stuck withdrawals and dust, each with a link to fix it. Works for any address; the share card shows only the score.

  Check a wallet

• Transaction preview

  Paste a transaction, a Permit or Permit2 signature request or a Solana transaction and see, in plain words, what leaves your wallet, what comes back, which permissions it grants and any drainer red flags.

  Preview a transaction

• Approvals

  See the token allowances your wallet has granted on Ethereum, Arbitrum, Base, Optimism, BNB Chain and Polygon, which spenders we can name, and revoke the ones you don't need.

  Review approvals

• Recover withdrawals

  Find Arbitrum and OP Stack withdrawals to Ethereum that were started but never claimed, and get the prove, finalize or claim transaction for your wallet to sign.

  Scan for withdrawals

• Unclaimed airdrops

  Check an address against airdrops we can verify on chain, such as the 2020 Uniswap airdrop and Merkl rewards. We only read; each result links to the official claim site.

  Check an address

1. 1

   Paste or connect

   Paste an address or a transaction, or connect your wallet. The checks read public chain data and simulate; they never ask for a signature.

2. 2

   Read the findings

   Each finding says what it is, why it matters and how serious it is, in plain words rather than hex.

3. 3

   Fix it yourself

   Revoke, claim, prove or sweep with a transaction your own wallet signs. LayerHop builds it; only you can send it.

• Recipient check

  Before you send to an address that isn't your own wallet, it is checked for look-alikes of addresses in your history (address poisoning) and for community reports.

• Token risk checks

  Before a buy, a token is checked for honeypots, high taxes and fakes pretending to be USDC, ETH or SOL. Community report counts show next to the risk badge.

• Fees before you sign

  Every quote shows the total fees before you sign, with the LayerHop fee as a percentage and as an amount of the token you send.
