Secrets-as-a-Service for Onchain Systems

Programmable Access Control for Agentic Onchain Workflows

Define and enforce who can decrypt, compute on, or attest to sensitive data—without leaking customer identities, counterparties, or business logic. Built for selective disclosure and audit-ready compliance.

The Data Access Control Gap

Agentic systems move faster than governance. Without cryptographic access control, sensitive workflows rely on “best-effort trust” and brittle offchain boundaries.

Unverifiable Data Pipelines

Sensitive inputs and decision signals traverse APIs, databases, and operators you can’t audit—making tampering, leakage, and silent policy drift hard to detect.

Autonomous Execution Amplifies Risk

When agents can move assets and trigger onchain actions, centralized data sources and privileged operators become systemic single points of failure.

No Standard for Policy + Key Governance

Onchain systems still lack a general way to encode who owns which data, what can be revealed, and under what conditions—with accountable key control.

Secrets-as-a-Service.
Enforced Onchain.

A programmable confidentiality layer for the next generation of digital economy: keep data encrypted end-to-end, while smart-contract policies and governed keys decide what can be computed, what can be revealed, and who can verify. Not just privacy, but granular control.

How It Works

1

Encrypt

Client encrypts sensitive inputs locally.

2

Submit

Encrypted data sent to compute network.

3

Compute

FHE evaluation on ciphertext.

4

Prove

Generate ZK proof of validity.

5

Verify

Contract verifies proof & updates state.

Trustless Setup

Compute Privacy

The compute operator never sees the plaintext. Data remains encrypted throughout the entire processing lifecycle.

Integrity

Correctness is cryptographically guaranteed by ZK proofs. You don't need to trust the operator's reputation.

Key Management

We support distributed key generation where no single entity holds the full decryption key.

Built for Compliant Onchain Finance & Operations

Move regulated, sensitive logic onchain—without exposing customer data, counterparties, or business secrets.

Private BTC-Linked Positioning

Take onchain positions while keeping strategy and exposure confidential.

Confidential Block Trades

Execute large OTC-style or block transactions with minimal information leakage.

Collaborative AML Without Data Sharing

Improve detection across institutions by sharing signals and verifiable results—not raw customer data.

Private Payroll & Compensation

Automate payroll logic onchain without revealing salaries or employee details.

Development Experience

1. Install SDK

Lightweight Typescript SDK to handle client-side encryption and key management.

npm install @wasder/fhelib

2. Submit Job

Send encrypted payloads to the compute network via a standard JSON-RPC interface.

3. Verify Onchain

Consume the result and proof in your Solidity smart contracts.
