Privacy Infrastructure
for Web3 Builders
SDKs for censorship-resistant settlement, confidential on-chain transactions, and zero-knowledge compliance — so you can ship financial infrastructure without rebuilding cryptography from scratch.
Ecosystem
Universal Privacy Stack
A Stablecoin No Counterparty Can Freeze
USDC and USDT can — and do — freeze balances on demand. For fintechs, payment rails, or treasury operations where settlement finality matters, that's a structural risk. UPD is a fully decentralized USD stablecoin: no admin keys, no blacklist, no issuer. Integrate it as a standard ERC-20 or use the SDK to mint, stake, and settle programmatically.
Confidential Transactions for Any ERC-20
On-chain activity is public by default — competitors can watch your order flow, payroll, and M&A moves in real time. UPP wraps any ERC-20 in cryptographic privacy via a shared Merkle tree. Shield assets, transact privately, and produce compliance proofs on demand. One SDK, no custom ZK circuits required.
Compliance Verification Without the Data Liability
KYC, accredited investor checks, and sanctions screening typically mean collecting and storing sensitive personal data — creating ongoing GDPR/CCPA liability. UPC verifies compliance via ZK proof: the user proves membership in your approved set, you see a valid proof, nothing else is revealed or stored. Drop the IAttestationVerifier interface into any existing smart contract.
Shared Cryptographic Primitives
Most ZK projects rebuild the same Merkle trees, hash functions, and proof verifiers from scratch — often with subtle differences and no shared review. UPH consolidates the cryptographic primitives underlying UPP and UPC into a single, consistently maintained package — built to be independently auditable and shared across integrations.
Institutional-Grade Rebalancing for UPD Stabilizers
Running a Stabilizer means managing delta-neutral hedging, funding fee optimization, collateral rebalancing, and liquidation risk — 24/7. UPR automates all of it. Proprietary software developed by quants, licensed to businesses that want to earn yield by backing the UPD stablecoin.
What We Build
Modular SDKs for the next generation of financial applications.
Permissionless Technologies builds the privacy infrastructure that financial platforms integrate rather than build themselves. Our stack covers three hard problems: a stablecoin no counterparty can freeze, a privacy pool for confidential ERC-20 transactions, and a compliance framework that proves identity without exposing it.
Each component is designed to be white-labeled: your platform, your rules, our cryptography. Integrate one SDK or all three — your users never need to know what's underneath. upd.io runs all of them together as a live reference implementation.
