Set up your wallet
Create or import
Click the Sombra icon in your toolbar.
- New to Sombra? Choose Create New Wallet, set an unlock password, and write down your 24-word recovery phrase. It's the only way back to your funds if you lose your device, and nobody at Sombra can restore it for you.
- Already have a phrase? Choose Import Seed Phrase and enter your existing 24 words.
Let the wallet take it from here
The first time it opens, Sombra runs a short Get Started guide and handles setup for you, in order:
- claims free DevNet SOL for network fees,
- grabs a few test tokens to play with (straight from the faucet),
- and registers your shielded address on Solana, the moment shielded mode goes live.
Follow the prompts to the end. You never have to leave the wallet to do any of it.
The three moves
Everything in Sombra is three moves. Shield turns public tokens into private ones, Transfer sends private tokens to anyone, and Unshield sends them back out to a normal Solana wallet. Your funds are private the whole time they're shielded, and you can take them out whenever you want.
Test tokens. This build runs on Solana DevNet. Tokens here are for testing and hold no real value. Sombra hands you free ones during setup.
Shield some tokens
A shielded transfer spends shielded funds, so put some in first. Open Shield, pick a token and amount from what you claimed, and confirm. Those public tokens become private notes that only you can read.
Send a shielded transfer
Open Transfer, switch to the Shielded tab, and pick one of the four built-in contacts (Alice, Bob, Carol, or Dave) so you always have someone to send to. Enter an amount and send.
Proof generation takes a few seconds. The wallet shows live progress the whole way.
Note: proofs are generated by a prover we run, inside a hardware trusted execution environment on NVIDIA Confidential Computing GPUs. Your witness sits in encrypted memory that nobody can read, us included. See Security.
Unshield when you want out
Getting funds back into the open is the mirror of shielding. Open Unshield, enter the destination Solana address (or tap Use my wallet for your own), pick a token and amount, and confirm. Sombra spends your private notes and pays that amount to the public wallet you chose, with the same live progress as a send.
Tell us what you think
That's the full loop! Public Solana tokens in, private shielded transfers across, withdraw funds safely back out. All signature-free, private, and quantum-secure. Tag @bonsol_labs on X, and tell us how it felt in the Sombra Telegram and Discord.
