KuraPrivacy
Privacy and compliance for public-chain finance Public blockchains make every transaction visible to anyone, which is a major barrier for financial institutions handling customer payments. KuraPrivacy is an on-chain privacy layer that keeps transaction details confidential while giving issuers, regulators and auditors the visibility they are entitled to. 1. Selective disclosure: each party sees only the information it needs. 2. Zero-knowledge proofs: transactions can be proven to follow the rules without exposing the underlying data. 3. Built for compliance: designed to support AML/CFT, Travel Rule and sanctions-screening obligations for stablecoin and tokenized-deposit issuers. Use cases: confidential stablecoin payments, B2B settlement, tokenized deposits.

Datachain Wallet
Enterprise smart-contract wallet with on-chain control Datachain Wallet is an ERC-4337 based smart-contract wallet built for businesses that hold and move digital assets. Wallet controls are enforced by the smart contract itself, on-chain, rather than by off-chain key-sharing schemes such as MPC. This makes control transparent and verifiable by anyone. 1. Passkey-based key management: secure sign-in with no seed phrases to store. 2. Organizational controls: approval workflows, multi-signature and other policy settings that mirror how companies govern their assets internally. 3. Standards-based: built on ERC-4337 account abstraction.
