1. Dual-Chain On-Chain Vaults
- BSC (Vault.sol + CEXStrategy.sol) and Solana (a single vault program with the CEX bridge built in) each hold user deposits independently
- A capped share of deposits can be deployed off-chain at any time, bounded by an on-chain exposure cap on both chains; the rest stays on-chain
- Deposit and withdrawal stay available at all times — a withdrawal queue handles the edge case where too much value is deployed off-chain at the moment a user requests out
