Protect every wallet transaction before it reaches the chain.
Demetrium adds a practical security layer to your RPC flow, helping you block common wallet-drain patterns while keeping everyday usage smooth.
What you get with Demetrium
The core controls needed to keep wallet activity safe while still getting transactions done.
Protected RPC on every request
Route wallet traffic through a safety layer that reviews risky transaction patterns before broadcast.
Works across major EVM chains
Use one familiar setup flow for Ethereum, Optimism, Arbitrum, Base, and BSC.
Custom guardrails, not one-size-fits-all
Set allow/deny rules, transaction limits, and swap diversion thresholds to match your workflow.
Clear decisions and activity visibility
See what was blocked, what was allowed, and why, with concise feedback and audit logs.
We built Demetrium after seeing a preventable wallet-drain attack up close.
The incident was painful, but not unusual. It looked like the kind of transaction pattern infrastructure should catch early.
Demetrium exists to make that protection practical: reliable guardrails, understandable feedback, and a setup flow people can actually finish.
How it works
Three steps from wallet request to safer execution.
Wallet sends request
Traffic routes through your protected Demetrium RPC endpoint.
Guardrails evaluate risk
Heuristics and policy checks flag suspicious approvals, transfers, and swap behavior.
You get a clear decision
Allowed and blocked outcomes are visible with clear, actionable context.
FAQ
Will Demetrium slow down normal wallet activity?
No. Decisions are made quickly, so everyday transactions still feel responsive.
Can I still complete a transaction if it gets blocked?
Yes. Wallets can offer explicit override paths when users intentionally choose to continue.
Do I need to change my contracts or dApp code?
No contract changes are required. Demetrium sits in front of the RPC layer you already use.
Is there an option for larger teams and infrastructure?
Yes. Enterprise plans include deeper integration options, including self-hosted deployment.
