Api Endpoint

RugShield Solana Tx Guard

Check an unsigned Solana transaction before signing. Send its base64 serialization; malformed input is rejected before payment. We simulate it on mainnet and return ALLOW, WARN or BLOCK with SOL and token balance changes and reasons, including dangerous approvals, owner changes, excessive outflows and redirected swaps. Solana only. The published sample is synthetic and only shows an HTTP 402 quote; replace it with a current unsigned transaction before paying.
