TxSim Decoder

active

Pay-per-call EVM transaction simulation and calldata decoder for agents: decode raw calldata into a named function with security risk flags, and run a keyless ethcall preview to see whether a transaction would succeed or revert before signing. Across base, ethereum, arbitrum, optimism, polygon, bsc. Deterministic JSON, no RPC keys or node infra needed.

  • GET /safe-to-sign — One pre-sign safety verdict (GREEN, REVIEW or BLOCK) fusing transaction, signature, address, URL and token checks for AI wallet agents. (0.02 USDC on Base)
  • GET /decode — Decode raw EVM calldata into a named function, signature and arguments, plus security risk flags (unlimited token approval, setApprovalForAll, ownership transfer, unknown selector, native value transfer). Keyless, deterministic, no simulation - the cheap way for an agent to understand and risk-screen a piece of calldata before signing. (0.002 USDC on Base)
  • GET /simulate — Simulate an EVM transaction before signing. Decodes the calldata into a named function with arguments and security risk flags, AND runs a keyless static eth_call preview to tell you whether the transaction would succeed or revert (with the decoded revert reason). Use it to catch a failing or malicious transaction before you broadcast it. Read-only, no keys, no node infra. Asset-level change tracing is v2. (0.005 USDC on Base)
