Problems

Why existing privacy solutions fall short for enterprises

Every transaction on a blockchain is visible to anyone. Simply "hiding" data, however, is not enough to meet regulatory requirements. The burden of key management and organizational operations also stands as a significant barrier to enterprise adoption.

Hiding data alone doesn't satisfy regulators

Rather than concealing everything indiscriminately, enterprises need the ability to disclose transaction details selectively — only to the parties that require them. Regulatory compliance, audits, and counterparty verification must all be achievable while preserving privacy.

Implementation and operational costs are too high

Integrating existing privacy solutions requires substantial engineering effort and often forces trade-offs on UX. Users end up managing a separate wallet or signing key, creating friction that undermines adoption. Building around these constraints while maintaining smooth UX is a significant hidden cost.

Privacy protection is insufficient

Many solutions fail to cover all three dimensions: anonymity, confidentiality, and unlinkability. The risk remains that a third party can still learn who sent how much to whom.

Key Features

Full Transaction Confidentiality

Covers all three dimensions — anonymity, confidentiality, and unlinkability — so that no third party can learn who sent what amount to whom.

Selective Disclosure

Transaction details can be disclosed only to the parties that need them, and only to the extent necessary, without granting payment authority. Regulatory reporting, internal audits, and counterparty verification are all achievable while preserving privacy.

Permissioned Transfers

A pre-configured allowlist can be applied so that only approved accounts are permitted to transact. This enables operations such as restricting transfers to KYC-verified users, supporting a wide range of compliance requirements.

Forced Transfer and Asset Freezing

Assets can be forcibly transferred based on pre-defined policies. This accommodates exceptional operational scenarios such as key-holder departure, regulatory action, and emergency asset recovery.

Compatible with Existing Wallets and Authentication

Works with authentication and signing methods already in use — including passkeys (WebAuthn), EOAs, and multisig — so enterprises can integrate without rebuilding their existing authentication infrastructure.

Low Gas Cost

KuraPrivacy achieves high gas efficiency compared to other privacy solutions. While a leading privacy protocol, Railgun, requires approximately 1.3 million gas per transaction, KuraPrivacy keeps that figure to around 400,000–500,000 gas.

Multi-Chain Support

Initial support covers EVM-compatible chains, with planned expansion to non-EVM chains such as Solana in future phases.

FAQ

Q1. Is KuraPrivacy compliant with regulatory requirements?

KuraPrivacy has compliance controls built into the protocol itself. Unlike some fully anonymous privacy solutions, it offers "privacy with auditability." Specifically, it provides selective disclosure of transaction details to designated parties, an allowlist that restricts transfers to approved counterparties only, and forced transfer and asset freezing capabilities designed to support regulatory and audit requirements. For more detailed information on regulatory compliance, please contact us directly.

Q2. How do I integrate KuraPrivacy?

Integration into existing services can be done simply via the Kura SDK / Service API. We will propose a specific integration flow and estimated workload based on your use case. A demo application is also in preparation. Feel free to reach out to us.

Q3. Are there any existing implementation examples?

Since the project announcement in March 2026, we have been exploring PoCs and joint projects with multiple service providers, stablecoin issuers, and financial institutions. Publicly shareable examples will be introduced individually.

Q4. How is pricing structured?

Pricing varies depending on your phase, scale, and use case. We will provide a detailed quote after an initial consultation to understand your requirements.
