What is Kleidi?

Kleidi is a firewall for your wallet. It protects you from sending funds to the wrong address or interacting with malicious smart contracts. Transactions that don't meet your security rules are blocked, keeping your funds safe.

How it works​

Kleidi sits between your wallet (like MetaMask) and the blockchain. Every transaction you make goes through Kleidi first, where it's checked against your security rules.
