Safe-first transaction security
Runtime DeFi Guard analyzes Safe transactions before signing and returns a signed, deterministic report. Use the public demo for one transaction, then add extension capture, policy enforcement, and co-signing when your Safe workflow needs it.
Safe required
Runtime Guard is not a generic wallet extension. It is designed for Safe transaction queues, Safe owner thresholds, Safe transaction hashes, Safe policies, and Safe co-signing. If you do not use Safe, the first step is understanding whether your DeFi operations should move behind one.
Products
Runtime Guard is the umbrella company. Runtime DeFi Guard is the current transaction-review and co-signing product. Runtime Lockdown Guard is the Safe timelock and panic-lockdown product.
Decode the Safe transaction, check the execution path, simulate effects where available, and produce a signed report for signers. Paid plans add extension capture and optional policy-based co-signing.
Explore DeFi GuardDesigned for Safe v1.5.0, Ethereum mainnet first. Lockdown creates a delay and lockdown mechanism for high-value Safes without moving funds out of the Safe.
Explore Lockdown GuardWorkflow
The product is a second channel before signature: parse the Safe transaction, explain what matters, and make the signer compare the right fields before approving.
Submit a Safe transaction URL manually or capture it through the paid extension workflow.
Runtime verifies transaction context server-side instead of trusting caller-supplied fields.
The engine decodes, simulates where available, and checks policy and technical risk gates.
Signers get verdict, action, parsed effects, hardware-wallet checks, and report verification data.
Public demo
Paste a Safe transaction URL and receive a signed light report. No login. No account. The free demo is capped at 5 reports per Safe per day.
Plans
Start with a no-login report, then move to extension workflow, co-signing, team audit trail, or Lockdown controls when the Safe justifies the setup.
