How it works
Three steps to private alerts
01
Connect your wallet
Your Solana wallet is your identity. No username, no password, no email required.
02
Encrypt your email
Enter your email once. It's encrypted in-browser before leaving your device — we never see it.
03
Get private alerts
Receive critical DeFi notifications directly to your inbox. No protocol knows your address.
Your inbox. Your privacy.
