Swap privately
Exchange supported assets directly from your private balance. Keep your trade amounts and activity out of public view.
Financial privacy should be easy, accessible and ubiquitous.
This is already expected of the world outside of crypto and with growing surveillance both offchain and onchain.
It is critical now more than ever that you have a safe haven for your money, true private property & ownership of your assets, and the freedom to make your own choices.
We are building Umbra to make this the default.
Send, hold, swap & earn
while keeping your money private.
Four ways to use your money with privacy built in. Move assets into a private balance, send and swap from one familiar interface.
Hold privately
Move supported assets from your wallet into a private balance. Keep your holdings out of public view while retaining ownership and control of your funds.
Earn privately
Earn up to 3.5% yield with USDv, a fully reserved digital dollar on Solana. USDv keeps your money liquid and productive while Umbra keeps it private.

Your Questions, Answered
Umbra lets you hold and send crypto privately on Solana. Unlike a regular wallet transfer, a payment between Umbra users does not publicly show who paid whom, how much was sent, or which token was used.
Read more: What is Umbra?
Connect your Solana wallet, register, and deposit supported tokens into a private balance. You can then send tokens privately to another Umbra user or withdraw them to a regular Solana wallet.
Read more: How it works · How Umbra uses proofs
Private transfers hide the sender, recipient, token, and amount from anyone viewing Solana. Deposits still show the wallet, token, and amount going in; withdrawals show the receiving address, token, and amount coming out.
Read more: What is public and private
Your individual private balance is not shown on the blockchain. Your device works it out from encrypted records, although some services that help process transactions can learn parts of your activity.
Read more: Who can see what · Privacy limits
No. You can use your existing Solana wallet. Umbra sets up the keys needed for private payments when you register, so there is no separate receiving address to manage.
Read more: Account setup · What registration reveals
It depends on how you want to pay them. If they have registered with Umbra, you can send them a private transfer to their existing Solana address. If they have not, you can still pay them by withdrawing to their address, but that withdrawal is public.
Read more: How Umbra works · Withdrawal visibility
Yes. A normal withdrawal shows the receiving address, token, and amount publicly, but does not show which private balance paid for it. Withdrawing to an address already linked to you can still reveal the connection.
Read more: What withdrawals reveal · How privacy can be lost
Yes, but with some limits. Private transfers hide payment details from public blockchain observers. Deposits, withdrawals, timing, and linked addresses can still reveal patterns, and services handling your requests may see your IP address or other information.
Read more: Privacy limitations
You do. Umbra is non-custodial and does not control your funds. Only your wallet holds the keys needed to spend your private balance.
Read more: Trust and security · Governance and upgrades
Umbra's documented protocol runs on Solana and supports SOL and approved Solana tokens. Not every token is eligible for deposit, and the protocol does not document direct bank-currency deposits.
Read more: Supported assets and design
Payments can have a protocol fee and a tip for the service that submits them. That service can pay the Solana network fee for a private transfer, but registration and deposits may still require SOL in your wallet.

Umbra cannot recover your private balance without the wallet used to create your account. Keep access to that wallet and its recovery method safe, because losing it may mean losing access to your funds.
