Most of the blockchains, including Solana, are pseudo-anonymous by design.
When you pay in a store, send money to a friend, receive your paycheck, or make any other on-chain action, you’re effectively giving anyone the ability to view your “bank account,” including all your transactions.
Managing multiple wallets without linking them together is difficult, and there are already tools that can easily correlate all your addresses if they interact with each other.

Zcash technology allows anyone to effectively protect their personal assets from bad actors. Thanks to its shielding features, users can anonymize their funds and keep them safe from unwanted attention.
Combined with NEAR intents, a user can easily “shield” their Solana by moving it into a new, anonymous account.

Privacy shouldn’t be a privilege.
If you’re an adult, you don’t want your neighbors knowing which porn subscriptions you pay for.
If you’re a company, you don’t want competitors seeing which services you purchased.
If you’re an influencer, you don’t want all of CT tracking every memecoin you buy.
If you’re doing financially well, you don’t want your entire balance visible to anyone you transact with.

Our solution lets users use and move their money privately—exactly the way it should be.

The Zcash Router SDK lets users privately move assets between Solana and Zcash using NEAR intents for seamless swap routing and status tracking.
Its core handles all logic, while account packages add chain-specific signing, address management, and balance operations.
With full support for Zcash shielded transactions, users can route SOL through Zcash and back to a fresh address—effectively anonymizing their Solana or funding a new private wallet.
The system is fully extensible to new chains and wallets, and includes an example app showing private swaps in both directions.
