Litesvm

Install LiteSVM and create a minimal Solana transfer test

Add LiteSVM as a development dependency and construct an in-process Solana VM test that funds an account, sends a transfer, and checks account balances.

Before you start

• A Rust project using Cargo.
• Solana program-testing dependencies matching the APIs used in the documented Rust example.

Steps

1. Add LiteSVM as a development dependency with the command below.

   Documented commandCopy command

   cargo add --dev litesvm

2. Import LiteSVM, Solana address, keypair, message, signer, system-transfer, and transaction types shown in the minimal example.

3. Create a sender keypair and destination address, instantiate LiteSVM::new(), and fund the sender with airdrop.

4. Build a transfer transaction using svm.latest_blockhash(), submit it with svm.send_transaction, and retrieve both accounts with get_account.

5. Assert the documented resulting balances: 4,936 lamports for the sender and 64 lamports for the recipient.

Guide limitations

• The documentation does not specify Rust, Solana crate, or dependency-version requirements beyond the shown imports.
• The documented example checks a simple transfer only; it does not provide a complete project file or test-run command.
• The example uses unwrap() and therefore does not document custom error handling.
