Gate News reports that on March 30, 2026, the Ripple research team proposed a privacy-preserving transfer solution for multi-purpose tokens (MPTs) on the XRP Ledger (XRPL). The paper, authored by Murat Cenk, Aanchal Malhotra, and Joseph Ayo Akinyele, introduces Confidential MPTs designed to support institutional and regulated use cases while allowing issuers to implement controls such as freezing and recovery.
This solution is an encrypted extension of the XLS-33 token standard, which was launched on the XRPL mainnet in October 2025. Confidential transfers ensure transaction correctness and balance sufficiency by using EC-ElGamal encrypted account balances, combined with non-interactive zero-knowledge proofs, without the need for validators to decrypt account information. Meanwhile, the identities of the sender and receiver remain visible, preserving the account model of the XRPL.
The paper’s abstract states that confidential MPTs provide an on-chain model for selective disclosure based on multiple encrypted balances and equivalence proofs, meeting regulatory and institutional demands while enabling cryptographic audit capabilities and accommodating a more streamlined issuer-mediated audit approach. This means institutional users can enjoy greater privacy protection during compliant transactions, while regulators can still execute necessary audits.
At the time of this research release, global regulators are adjusting their stance on on-chain privacy. A report submitted by the U.S. Treasury in early March acknowledged that legitimate digital asset users might rely on mixers when trading on public blockchains. Ripple is also strengthening XRPL network security by launching an AI-driven security strategy to enhance the robustness of the entire ecosystem.
The introduction of this privacy transfer solution will provide safer, more controllable, and compliant privacy features for multi-purpose token transactions on the XRPL, potentially promoting institutional adoption of XRPL for high-value digital asset operations and setting a precedent for future public blockchain privacy standards.
