A drainer only needs one approval. Nova Shield checks the request, names the spender and shows what can move, so the decision is not blind.
A known router or an unknown contract deployed last week — the difference is shown before approval.
The exact token and amount the contract may transfer, not a raw hex number.
Unlimited approvals are normal for staking and abnormal for a claim page. Nova says which one you are looking at.
Batched signatures (EIP-7702 style) can chain several actions. Nova shows the whole batch, not just the first step.
Drainer losses in 2025 reached $83.85M across 106,106 victims. The average ticket fell to $790, which means attackers now rely on volume: many small approvals, not a few large ones. Volume is exactly what a screening layer stops.
It is not a guarantee and not a virus scanner. It is a signature-level check: it explains the request and flags the patterns drainers use. The final approval is still yours.
A wallet that screens signature requests for drainer patterns before the user approves them.
It flags known patterns and explains the spender and amount. The approval remains the user's decision.
Yes, in the mobile app and the browser build.
Yes. Nova Shield is part of the wallet, with no subscription.
