Ripple’s researchers have released a new paper detailing how to improve transaction privacy on the XRP Ledger (XRPL).
This paper details Confidential Transfers for Multi-Purpose Tokens (Confidential MPTs), which are designed to support institutional and regulated applications. A key feature is the ability for issuers to control the tokens, including options to freeze or reclaim them.

A new research paper from Ripple’s Aanchal Malhotra, J.A. Akinyele, and Cenk proposes a new type of token called confidential MPT tokens (XLS 33). These tokens hide the amount and details of transactions while still allowing anyone to verify the total supply. The goal is to make the technology suitable for use by banks and other regulated institutions, offering features like the ability to freeze or reverse transactions.

This paper was written by Murat Cenk, Aanchal Malhotra, and Joseph Ayo Akinyele. It proposes Confidential MPTs, a new security feature building on the XLS-33 token standard that launched on the XRPL network in October 2025.
This system replaces simple account balances with encrypted data using EC-ElGamal. It then uses a special type of proof – a non-interactive zero-knowledge proof – to ensure transactions are valid and accounts have enough funds, all without needing validators to decrypt the account information.
Meanwhile, sender and receiver identities remain visible, preserving XRPL’s account-based model.
Confidential MPTs meet the necessary rules and standards by using a special type of encryption that allows for audits on the blockchain. This system lets information be revealed selectively and proves its accuracy, but it can also work with more straightforward audit methods managed by the issuer.
This development comes as regulators are starting to reconsider how they view privacy on blockchains. Just last month, the US Treasury Department told Congress that people legitimately using cryptocurrencies sometimes need to use mixers when making transactions on public blockchains.
The US Treasury recognizes that people have legitimate reasons for wanting privacy when using public blockchains.
We’re addressing this on XRPL with Confidential MPTs, which provide regulators with the visibility they need while protecting user privacy.
This approach represents the future standard for blockchain technology.

Ripple is releasing a privacy report while also improving the security of its network. The company recently detailed a new, AI-powered security plan for XRPL.
