Transaction Simulator

Validate Solana transactions before execution

Transaction Simulator validates blockchain transactions BEFORE execution.

It simulates swaps via Jupiter API, detects honeypots and rug pulls via GoPlus API,

and estimates slippage to protect AI agents from malicious tokens and failed transactions.
