Trust
There is nothing to steal from us.
Other tools need to know your on-chain addresses, your keys or your financial identity. We do not. Kronobi asks for none of your wallets, none of your keys, not the slightest access to your crypto. The day anyone tried to attack us, there would simply be nothing usable to take.
Zero on-chain address
We never ask for your wallets or your addresses. Nothing to link to your identity.
Your keys stay with you
They never leave your device. Kronobi never sees them.
No real crypto
The decoy holds no assets. Your real crypto stays on Ledger, MetaMask, your usual wallets.
