Good for

wallet teams adding privacy-preserving token flows
builders comparing Railgun and Privacy Pools integrations
privacy-first account abstraction experiments

Avoid for

production apps that need every Kohaku package to be mature; several docs and packages are marked WIP
privacy requirements that need a complete hosted product rather than SDK/tooling components

Readiness score

73/100

Readiness measures how much verified integration surface exists for builders and agents. It does not mean the protocol is easy to use — integration difficulty is tracked separately.

Capabilities

Privacy-first wallet SDK collection beta

Best for: wallets that want privacy protocol modules without hard-coding one provider, privacy UX research across shielding, unshielding, private RPC, and account separation

Kohaku docs state some parts are work in progress and not ready for production use.

Kohaku wallet reference implementation alpha

Best for: reference UX for embedding onchain privacy into Ethereum wallets, Sepolia testnet privacy demos

Kohaku Wallet is described as active development and Sepolia-only.

Composes with

railgun privacy_layer supports

Kohaku can use Railgun-style private token flows as part of wallet privacy experiments.

privacy-pools privacy_layer supports

Kohaku tracks Privacy Pools concepts for compliant privacy and association-set experiments.

helios privacy_layer supports

Helios can reduce trusted RPC dependency for privacy-sensitive wallet clients.

Known issues

Kohaku contains WIP packages and reference-wallet code medium confirmed Workaround: Treat Kohaku as a privacy tooling track and integration reference. Validate each package separately, and prefer production-marked package capabilities such as Railgun where appropriate.
