How fast are the built-in private token transfers?

As of now, we have a built-in optimized System Program for the following:
  • Transfers & unshields (SOL/SPL) => 1 Solana tx (400ms) + 1-2.5s proof generation
  • Shields (SOL) => 1 Solana tx (400ms) + 1-2.5s proof generation
And a not-yet optimized System Program for:
  • SPL shields => 2 Solana txs (800ms) + 1-2.5s proof generation
Note that proof generation time varies based on the user's device.
You may notice that currently, the methods shield, transfer and unshield of the user class are slower than what is described above. That's because user methods currently still await the full closure of the process (the point at which the outputs of a transfer can be spent again). The above benchmarks account for the point at which the correctness of the transfer is mathematically verified and guaranteed and the transfer inputs are spent.

Where is Light deployed?

Light v3 is currently deployed on Solana Testnet.
You can additionally deploy it on a local Solana instance for testing.

Wen Solana-Mainnet?

. We'll harden Testnet over the next weeks and months, add new features, and improve performance and developer experience.

What's a Private Solana Program?

PSPs are Solana programs with public and private on-chain state and state transitions. You can choose which data, addresses, and transactions you want to be private and which public. This is important for applications where you might want or need specific parts to be transparent (e.g. publicly shared game state).

I have an infrequently asked question!
