Count your coins, privately.
Look up any BTC address balance, without revealing the address to anyone – not even us.
The ultimate in BTC privacy.
All information about the addresses you look up stays on your device. The Spiral server learns nothing about your queries.
Tighten your OpSec.
When you use a block explorer, you're linking your identity with your money, inviting phishing. Spiral offers the privacy of a self-hosted node, with zero maintenance.
Built on strong cryptography.
Spiral uses fully homomorphic encryption to guarantee your privacy. Read our paper or check out our source code for details.
