Canton DeFiMultichain DeFi Vault Technical Reference

Overview ​

The Canton and Multichain DeFi Vault provides a robust technical blueprint for regulated institutions engaging with permissionless DeFi protocols. This architecture solves the fundamental conflict institutions face: maintaining stringent, auditable governance and data privacy while accessing the highly liquid execution environments of public blockchains.

System Architecture ​

The Canton DeFi implements a three-layer architecture that separates policy, orchestration, and execution:

Key Concepts ​

Hybrid Execution Paradigm ​

• Canton Network serves as the confidential Policy and Control Plane
• Public Blockchains (EVM, Solana, etc.) function as the Execution Layer
• Cryptographic intents bridge the two layers securely

Architecture Layers ​

1. Canton Domain (Daml Runtime) - Policy, governance, and strategy computation
2. Private Oracle Agents - Secure data feeds for strategy decisions
3. Relayer/Bridge Layer - Verifiable intent translation and submission
4. MPC/Custodial Signers - Secure asset custody and transaction signing
5. Public Smart Contract Vaults - Minimal execution environments on target chains
