Silent Shard
Enterprise Policy Engine
Turn compliance and risk policy into enforceable rules across every wallet, workflow, and blockchain.
Define the transaction boundary.
Allow or deny wallets, contracts, tokens, methods, selectors, and parameter values.
Control behavior over time.
Set velocity, exposure, transaction-count, and operating-hour limits.
Act on live risk.
Use KYC, AML, Travel Rule, sanctions, and custom scores. Freeze on alert and fail closed by default.
Separate duties by design.
Keep authors, initiators, approvers, auditors, and operators within distinct permissions.
Deploy where the policy demands
Run on-prem, across a distributed environment, or in a Silence-hosted sandbox.
The control model stays consistent.
On-Prem (Distributed)
Deployed across multiple MPC network nodes for redundancy, decentralization, and censorship resistance.
On-Prem
Supports data-residency requirements and compliance rules, removing reliance on Silence infrastructure.
SaaS Sandbox
Hosted by Silence as an external service, with the fastest path to a running environment.
Transaction simulation
Before signing, the engine runs a full preapproval simulation to determine the exact effect on wallet balances and token holdings
Policy simulation
Test policy behavior against transaction sets and synthetic rules before enforcement, then surface thresholds, approval standards, and blocking conflicts.
