Ethereum Mainnet • European Union & UK

Transaction Decoder for protocol security teams

Translate raw transaction calldata into plain-English explanations with risk annotations. Focus on smart contract security, counterparty risk, and operational safeguards for treasuries and protocols. Detect anomalies, suspicious approvals, and governance changes before funds are at risk. MiCA, ESMA guidance, and FCA rules define comprehensive disclosure and reserve requirements.

  • Decode function calls, parameters, and event logs across major protocols.
  • Risk heuristics highlight suspicious approvals, proxy calls, or value transfers.
  • Generate shareable summaries for investors, compliance, or community updates.
  • Proactively identifying malicious approvals and upgrade patterns is tedious.
