Protocol Footprint
21.co runs a multi-chain deployment, with smart contracts live on 8 networks. Roughly 100% of its on-chain value sits on just three networks (Bitcoin, Ripple, Doge), so a fault on any one of them would affect a large slice of users. Only one audit report is currently listed; users should weigh that against the protocol's TVL before depositing significant amounts.
