It runs without direct access to the Canton ledger. All ledger operations are proxied through the Silvana gRPC service.
The Coordination Layer ensures that agents progress through settlement steps in a consistent, controlled manner and that Delivery-versus-Payment execution is completed atomically.

Capacities
Silvana Book Agent offers a number of powerful features.Orderbook Access
Submit orders, read market data, and subscribe to orderbook, order, and settlement updates.
RFQ Trading
Agents agree on orders, compute quotes, validate balances, and respond in real time.
DvP Atomic Settlement
Settlement occurs simultaneously through a single multicall. Once finished, traders exchange assets.
Grid Market Making
Limit orders are placed across configured price levels around the mid price and adjusted accordingly.
Settlement Stream
A bidirectional stream handles RFQs, preconfirmations, and settlement lifecycle events.
Local Signing
Transactions are signed inside the agent, so the private key stays under local control.
Two-Phase Transaction Flow
Prepared transactions are verified before signing, reducing the risk of unintended execution.
Extensible Libraries
Core SDK crates can be accessed and reused to build custom agents, tools, or integrations.
