FAQ - Devnet
Light v3 is currently deployed on Solana Devnet.
You can additionally deploy it on a local Solana instance for testing.
Set the rpcUrl to devnet. We recommend you use a private RPC provider, such as Helius or Triton.
You can optionally access a hosted Light Relayer instance for testing:
Set the
relayerUrl (e.g., in your CLI config or when initializing the relayer in your app) to: https://v3-devnet-relayer-7x44q.ondigitalocean.app.

The relayer is currently also used for indexing purposes and requesting transactions. You can host your own Devnet or Localnet relayer as well. You can find the code here.

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

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.
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).
