@lightprotocol/cli

ZK Compression CLI

CLI to interact with Light Protocol and ZK compression.

Requirements

• Ensure you have Node >= v20.9.0 installed on your machine.

• You will need a valid Solana filesystem wallet set up at ~/.config/solana/id.json. If you don't have one yet, visit the Solana documentation for details. The CLI will use this wallet as the default fee payer and mint authority.

Installation

Using npm

npm install -g @lightprotocol/cli

Building from source

If you prefer to build the CLI from source, follow the steps below to install the necessary prerequesites.

1. Activate the Development Environment

Ensure you are at the root of the monorepo.

. ./scripts/devenv

2. Install and build the monorepo from source. This also builds the CLI.

./scripts/install.sh

./scripts/build.sh

3. Make your CLI available globally

pnpm link --global

# Verify the CLI was correctly installed
which light

Usage

1. Once globally installed, start the Light test validator

light test-validator

This starts a Solana test-validator with the Light system programs and accounts, a prover server, and the Photon indexer as background processes against a clean ledger.

# Pass --skip-indexer to start without the indexer
light test-validator --skip-indexer

# Pass --skip-prover to start without the prover
light test-validator --skip-prover

Note: The CLI currently runs the photon indexer and gnark-prover as background processes at port: 8784 and 3001 respectively.

2. Ensure you have sufficient localnet funds

# Airdrop 1 SOL
solana airdrop 1

# Print your address
solana address

# Print your balance
solana balance

Now you're all set up to run CLI commands :)

Commands

Create a compressed token mint

light create-mint

USAGE
  $ light create-mint [--mint-keypair <value>] [--mint-authority <value>]
    [--mint-decimals <value>]

FLAGS
  --mint-authority=<value>  Path to the mint authority keypair file.
                            Defaults to default local Solana wallet file
                            path.
  --mint-decimals=<value>   Number of base 10 digits to the right
                            of the decimal place [default: 9].
  --mint-keypair=<value>    Path to a mint keypair file. Defaults to a
                            random keypair.

Mint compressed tokens to a Solana wallet

light mint-to --mint "YOUR_MINT_ADDRESS" --to "YOUR_WALLET_ADDRESS" --amount 4200000000

USAGE
  $ light mint-to --mint <value> --to <value> --amount <value>
    [--mint-authority <value>]

FLAGS
  --amount=<value>          (required) Amount to mint.
  --mint=<value>            (required) Mint address.
  --mint-authority=<value>  File path of the mint authority keypair.
                            Defaults to local Solana wallet.
  --to=<value>              (required) Recipient address.

Transfer compressed tokens from one wallet to another

light transfer --mint "YOUR_MINT_ADDRESS" --to "RECIPIENT_WALLET_ADDRESS" --amount 4200000000

USAGE
  $ light transfer --mint <value> --to <value> --amount <value>
    [--fee-payer <value>]

FLAGS
  --amount=<value>     (required) Amount to send.
  --fee-payer=<value>  Fee payer account. Defaults to the client
                       keypair.
  --mint=<value>       (required) Mint to transfer
  --to=<value>         (required) Recipient address

Compress native SOL

Note: Ensure the SOL omnibus account of the Light system program is already initialized by running: light init-sol-pool

light compress-sol --amount 1000 --to "YOUR_WALLET_ADDRESS_BASE58"

USAGE
  $ light compress-sol --to <value> --amount <value>

FLAGS
  --amount=<value>  (required) Amount to compress in lamports.
  --to=<value>      (required) Specify the recipient address.

Decompress into native SOL

light decompress-sol --amount 42 --to "YOUR_WALLET_ADDRESS_BASE58"

USAGE
  $ light decompress-sol --to <value> --amount <value>

FLAGS
  --amount=<value>  (required) Amount to decompress in lamports.
  --to=<value>      (required) Specify the recipient address.
