Kleros Scout MetaMask Snap

How to use the Snap’s features?

Once you install the Kleros Scout Snap, with every txn/contract interaction, you will see a tab which provides you with insights around the same. Upon installation, If you see this, you are already using community curated contract insights for secure dapp interaction - the most important feature of the Kleros Scout Snap.

​
Limitations

The Snap explicitly does not:
  • Endorse any contract interaction
  • Use centralized whitelisting: all data is community-curated
  • Guarantee 100% accuracy or accept liability for insights

Knowledge Base

Kleros Curate is a decentralized dApp used to create open curated registries. Financial incentives and dispute resolution maintain the quality and policy compliance of every entry.
Community members submit items with deposits, and anyone can challenge a submission during a vetting period. Unchallenged entries are approved; challenged ones go to Kleros jurors for resolution. No single party controls the registry.
Centralized parties have financial incentives to whitelist tokens or manage address tags for profit, which creates vulnerabilities to phishing and manipulation. Decentralized, community-secured data removes that single point of failure.
Yes, community submissions are encouraged. See the Scout Tutorial for step-by-step guides to making submissions to the three security metadata registries.
Two things: incentives (Kleros runs regular programs rewarding active submitters, see Earn with Scout) and community benefit (there is minimal risk in submitting known-safe contracts you have used, and doing so protects thousands of users).
