⚠ Error
⚠ Unlimited Token Approval Detected
This transaction gives a smart contract unlimited permission to move tokens from your wallet — meaning it can transfer every single token of this type you own, now or in the future, without asking again. This is a standard pattern used by DEXs like Uniswap to save you gas on future swaps, but it carries real risk: if that contract is ever hacked or is malicious, your entire token balance could be drained.
▸ Safer alternative: approve only the exact amount you need, plus ~10% buffer.
▸ After you're done using the platform, revoke the approval at revoke.cash — it's free.

      ⚠ Error
      
    
    

    
    
      ⚠ Action recommended: You have unlimited token approvals active.
      Visit revoke.cash — paste your wallet address there,
      find each unlimited approval listed below, and revoke it. This removes the contract's permission to move your tokens.
      It costs a small amount of gas (usually under $1) and is one of the best security habits in crypto.
