Solana transaction safety check before signing (pre-sign guard, wallet drainer d
Solana transaction safety check before signing (pre-sign guard, wallet drainer detection). Send the unsigned tx as base64; we simulate it on mainnet and return ALLOW, WARN or BLOCK with exact SOL and token balance changes and why: owner reassigned, unlimited approval, account closed to a third party, Token-2022 permanent delegate, SOL outflow above intent, swap output redirected. Solana only. 1,132 mainnet cases: 100% of attacks blocked, 0.13% false blocks, p95 1.0 s.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
