Bridge
Settles on Base
No new chain, no new token. Cipher is a Layer 2 anchored by a settlement contract on Base mainnet — finality is Base finality.

Verification is roughly ten milliseconds. The validator role is verify-only — proof generation stays with the user. Home PCs and single-board computers can participate in consensus.
