About Permissionless Technologies
Privacy infrastructure for institutional-grade DeFi — our vision, mission, and the problem we solve.
Permissionless Technologies
Vision
We build privacy infrastructure for institutional-grade DeFi — a vertically integrated stack from a non-freezable stablecoin, through a multi-token privacy pool, to a composable compliance framework, backed by audited cryptographic primitives.
Every component is an SDK. Not a monolith. Each piece is independently installable, auditable, and reusable by third parties.
The Problem
DeFi is transparent by default. Every address, balance, and transaction is public on-chain. This creates two opposing pressures:
Privacy is essential for real adoption:
- Businesses cannot operate when competitors can read their on-chain activity
- Individuals face wrench attacks and targeted theft when their balances are public
- Front-running and MEV exploit transparent mempool data
Compliance is non-negotiable for institutions:
- Regulated entities cannot interact with unauditable protocols
- Sanctions screening requires knowing who you're transacting with
- Regulatory pressure on privacy protocols is increasing globally
Existing solutions force a binary choice: either full transparency (traditional DeFi) or full privacy with no compliance path (Tornado Cash). Neither works for institutional adoption.
Our Answer
Privacy and compliance are not opposites. We prove you can have both.
Our approach, drawn from the Privacy Pools research and extended with production-grade engineering:
- Privacy is enforced at the protocol level via zero-knowledge proofs. No central party can see your transactions.
- Compliance is enforced at the protocol level via ASP (Association Set Provider) membership proofs. Verifiers learn "someone in the approved set did this" — never who.
- No admin keys. No blacklists. No back doors.
Mission
Build the cryptographic primitives and SDKs that make privacy-preserving, compliance-ready DeFi accessible to any developer, institution, or protocol — without requiring them to understand the underlying ZK mathematics.
What We Build
| Product | What | npm Package |
|---|---|---|
| UPD | Non-freezable $1 stablecoin | @permissionless-technologies/upd-sdk |
| UPP | Privacy pool for any ERC20 | @permissionless-technologies/upp-sdk |
| UPC | Pluggable ZK compliance framework | @permissionless-technologies/upc-sdk |
| UPH | Audited cryptographic primitives | @permissionless-technologies/uph (planned) |
Technology Stack
All packages are built on the modern Ethereum developer stack:
- viem for Ethereum interaction (not ethers.js)
- wagmi for React hooks
- TypeScript with strict mode
- ESM modules with CJS fallback
- AGPL-3.0 or later
GitHub Organization
All packages live under the permissionless-technologies GitHub organization and are published as @permissionless-technologies/* on npm.
