Arcana

Arcana is a general-purpose sidecar architecture for applications that require fast, deterministic state execution alongside on-chain security guarantees. It operates next to a main chain, currently EVM, and divides system responsibilities along clean architectural lines.

The on-chain layer handles custody, deposits, withdrawals, and optional state checkpoints, all enforced through Solidity contracts including UserVault and BackupRegistry. The off-chain layer runs application logic as WASM stat
