Confidentiality has always been a key pillar of Polymesh. Since inception, the network has enforced identity and compliance at the protocol level, but privacy –– long recognized as essential for wide-scale institutional adoption –– remained a puzzle. That’s about to change.

We’re proud to announce Confidential Assets on Polymesh, powered by P-DART, a new privacy-preserving tokenization and settlement framework that will debut for early testing on the new Polymesh DevNet. 

Be first to access it.

Developed by researchers at Polymesh Labs and the University of Edinburgh, P-DART (Polymesh-DART) extends the DART protocol to support the issuance and settlement of confidential asset transfers on Polymesh. 

It’s achieving that balance of confidentiality and compliance that institutions have long sought to navigate both privacy requirements and regulatory obligations.

Overview of the P-DART Protocol

At a high level, P-DART brings four innovations to Polymesh’s settlement layer: 

‍

Confidential settlement mechanism

Every transfer is represented as a settlement, defined by its sender, receiver, asset type, and amount. Each leg of the transaction is encrypted and validated via zero-knowledge proofs (ZKPs), ensuring no public leakage of asset, value, or participant information while maintaining verifiability onchain. 

‍

Dual oversight model

In addition to traditional auditors, P-DART introduces mediators: authorized, pseudonymous entities that can affirm or reject transactions if compliance review is required. This ensures both retrospective auditability (via auditors) and prospective regulatory control (via mediators). 

‍

Full privacy with constant transaction size

Using advanced cryptographic commitments and accumulators, transaction size remains constant regardless of network activity, preserving scalability even under heavy institutional loads.

‍

Proof-of-balance protocol

Participants can privately prove sufficient balances for settlement without revealing holdings, which is critical for compliance attestations and trade affirmation workflows. 

‍

Why confidentiality matters for regulated markets

‍

In capital markets, confidentiality is compliance. Participants require privacy to protect counterparty identities, trade sizes, and strategies, but regulators demand auditability and enforcement. P-DART provides both.

P-DART transforms Polymesh into a blockchain capable of private, regulated settlements, supporting use cases from tokenized debt and private placements to bilateral repo trades and off-exchange clearing, all while maintaining the onchain governance, identity, and compliance guarantees Polymesh is known for. 

‍

Confidential assets on DevNet

To ensure a smooth rollout, Confidential Assets will debut first on Polymesh DevNet, a new sandbox environment for developers, custodians, and institutions to experiment with the framework before mainnet migration. 

Participation in the DevNet helps to finalize the framework and inform parameters ahead of the mainnet release.
