Solution

Silvana is built as a layered execution platform. Each layer has a specific responsibility, but together they form one system for controlled automation: agents prepare actions, workflows are coordinated, sensitive data remains protected, proofs make outcomes verifiable, and final settlement is executed through Canton’s DvP infrastructure.

​

Execution Layer

The Execution Layer is where agents perform actions. Execution is not tied to a single environment and can run:

• off-chain
• on another blockchain
• in the cloud
• inside a user-controlled private environment
• within a Trusted Execution Environment (TEE)

Agents handle the actual work. Developers can build agents themselves, integrate existing agents from external environments, or use agents provided by Silvana.

​

Coordination Layer

The Coordination Layer orchestrates how agents, applications, proofs, and settlement flows work together. It handles a wide range of workflow coordination functions, including:

• Sequencing agent actions in the correct order
• Batching multiple operations into a single coordinated process
• Routing tasks, messages, and transactions between agents and systems
• Orchestrating multi-step transactions and cross-system workflows
• Automating business processes based on predefined rules and conditions
• Managing workflow state and tracking progress across execution stages
• Synchronizing actions between multiple agents, applications, and environments
• Coordinating dependencies, approvals, and event-driven triggers throughout a workflow

The Coordination Layer is built on a fast chain, enabling Silvana to support ultra-fast coordination at low transaction costs.

​

Privacy-Preserving Layer

The Privacy-Preserving Layer makes execution verifiable without exposing confidential data. Silvana uses zero-knowledge proofs, selective disclosure, TEE-based confidential execution, and MPC-based integrations to protect sensitive information while still allowing users, counterparties, auditors, or applications to verify outcomes.

​

Settlement Layer

The Settlement Layer finalizes asset transfers and anchors execution results. Silvana uses Canton’s DvP settlement infrastructure to ensure that delivery and payment happen together. Assets move only when all settlement conditions are satisfied. If one side fails to meet its obligations, settlement does not complete, and the transaction rolls back. A two-phase transaction model also helps to keep settlement secure while abstracting low-level ledger, allocation, confirmation, and synchronization complexity from developers.
