Resources
Good for
- private token shielding and unshielding
- private transfers between 0zk addresses
- wallets adding private balances and private DeFi flows
Avoid for
- apps that only need anonymous group signaling or voting
- products that cannot handle compliance, proof-of-innocence, relayer, fee, and user-education requirements
91/100
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
Shield and unshield ERC-20 tokens production-ready
Best for: wallets that need private token balances, apps that need shielded deposits and withdrawals on existing EVM chains
- Shielding and unshielding require fee, relayer, disclosure, and compliance UX that the app must design.
Private DeFi interactions production-ready
Best for: private swaps, lending, and dApp calls without leaving the user's preferred chain, wallet-integrated private DeFi
- Builders need to verify adapter support, broadcaster fees, pool liquidity, and proof-of-innocence policy before production.
Composes with
kohaku privacy_layer supports
Kohaku can use Railgun private token flows as part of wallet privacy tooling and experiments.
uniswap supporting_protocol supports
Railgun private DeFi flows can involve swaps and liquidity interactions that eventually touch public AMM liquidity.
privacy-pools alternative alternative
Privacy Pools is a related privacy primitive direction focused on association sets and proof-of-innocence concepts.
