Beehive is our validator business on Cosmos networks. We built every tool around it ourselves.

Keys stay on your device. Staking, plus alerts when money moves or a validator goes down.
Node monitor
A live dashboard and a Telegram bot that wake us up when a node misses blocks.
Voting system
Validator voting on an EVM chain: server, block scanner, desktop console and two Android apps.
Exchange console
