Umbra is the only answer to this, and it isn't close There are two core aspects that make up Railgun: 1. The wallet frontend, where you can swap / transfer privately 2. The SDK, where any EVM project can apply Railgun's privacy features Umbra is comprised in a similar way, where the frontend wallet is available to swap / transfer privately, and shield any native SPL token. In theory, Umbra can have hundreds of shielded pools such that you can swap to any asset privately, you can even make Bitcoin private via a WBTC shielded pool. Umbra can make any token private Additionally, the Umbra SDK can be implemented into any native Solana project, giving Umbra privacy to anything in the Solana ecosystem. There are multiple projects that have already integrated the SDK, and many more in the pipeline Though a key difference between the two, and why I would give Umbra a distinct edge over many competitors, is the relationship between the token $Umbra and the underlying business IP. Through ownership governance, investors have direct utility into the Umbra IP, you hold ownership in the business, can make decisions with tokens, and have a direct relationship with the team. This is not a gas-token, nor is it an emissions-token, this is a pure utility driven token that has direct exposure to the underlying business > Revenue from the wallet is distributed to the Umbra IP >> Revenue from any project using the Umbra SDK is distributed to the Umbra IP With ZK / MPC hybrid setup, Umbra is the most pure form of privacy on Solana, with multiple available revenue streams, with an ownership-token structure that directly benefits token holders Higher
