UPP — Universal Private Pool

npm: @permissionless-technologies/upp-sdk

A privacy layer that enables private transactions for any ERC20 token through a shared Merkle tree. Users shield tokens, transact privately, and withdraw with optional compliance proof.

Key capabilities:

• Shield any ERC20 token into a shared anonymity pool
• Private transfers, merges, and splits via ZK proofs (Groth16 SNARK + Circle STARK)
• Stealth addresses — hash-based, post-quantum secure, bech32m encoded
• Per-transaction viewing keys for selective disclosure and auditing
• Ragequit — original depositors always exit, even if ASPs refuse

Dual proof system:

• SNARKs (Groth16/BN254) — everyday transfers, ~200K gas, ~200B proofs
• STARKs (Circle STARK/M31) — post-quantum vault, ~20M gas, ~5KB proofs

UPC — Universal Private Compliance

npm: @permissionless-technologies/upc-sdk

A standalone, pluggable framework for zero-knowledge compliance verification. An ASP (Association Set Provider) maintains a Merkle tree of approved identities. Users prove membership via ZK proof without revealing who they are.

Key capabilities:

• PLONK proofs over BLS12-381 (128-bit security, via EIP-2537 precompiles)
• Universal setup — no per-circuit trusted setup ceremony
• IAttestationVerifier interface — plug in Semaphore, WorldID, zkPass, or custom backends
• IASPProvider interface — Memory, LocalStorage, REST, or custom storage
• AttestationHub on-chain registry — discoverable ASP list per chain
• Sub-packages: upc-asp-whitelist (auto-whitelist), upc-asp-kyc (planned), upc-asp-sanctions (planned)

UPD — Universal Private Dollar

npm: @permissionless-technologies/upd-sdk

A non-freezable, decentralized stablecoin pegged 1:1 to USD. Backed by overcollateralized stETH. No admin keys. No blacklist. Standard ERC20 — works everywhere.

Key capabilities:

• $1 USD peg, stETH collateral, on-chain verifiable reserves
• StabilizerNFT system — collateral management with priority-ordered liquidations
• EIP-2612 permit support for gasless approvals
• sUPD — staked UPD with ~8-10% APY target
• Native UPP integration for private transactions

9 smart contracts: UPDToken → StabilizerNFT → PositionEscrow → StabilizerEscrow → PriceOracle → OvercollateralizationReporter → InsuranceEscrow → BridgeEscrow → sUPD

UPH — Universal Private Helpers

npm: @permissionless-technologies/uph (planned)

A library of audited, reusable cryptographic primitives extracted from UPP and UPC. One audit, many users.

Planned Solidity libraries:

Planned TypeScript utilities: Stealth address generation, LeanIMT Merkle tree, Poseidon hash wrappers, note encryption/decryption.

UPR — Universal Private Rebalance

Proprietary — licensed to qualified businesses

Institutional-grade software that automates the operational complexity of running a UPD Stabilizer: delta-neutral hedging, funding fee optimization, collateral rebalancing, liquidation prevention, and multi-exchange position management.

Key capabilities:

• Automated delta-neutral hedge management across CEX perpetual futures
• Funding fee capture and yield optimization (~20–35% APY target)
• Real-time collateral ratio monitoring and rebalancing
• Liquidation risk prevention and corrective action
• FIFO mint / LIFO burn queue position optimization
• Multi-exchange integration for best execution
