Practical overview

When it fits

Use it when Solana access, wallet prototyping and testing utilities need to be integrated into a Rust and WebAssembly development workflow.

Who it is for

  • Rust developers building browser-based Solana applications.
  • Teams prototyping browser wallet integrations.
  • Developers writing Solana program and WebAssembly integration tests.

Documented uses

  • Query Solana account information and balances through a WebAssembly RPC client.
  • Send transactions and interact with Solana programs from browser-oriented Rust code.
  • Create an in-memory wallet for testing transaction and message signing.
  • Set up Solana integration tests with test validators, accounts and predefined keypairs.
  • Keep snapshot tests stable by redacting dynamic signatures and timestamps.
Before you choose

Requirements & limits

The repository is publicly visible and licensed under the Unlicense.

  • The main client targets Solana RPC interaction from browser or other WebAssembly runtimes.
  • The memory wallet is documented for testing and prototyping rather than established production wallet security.
  • Testing support spans program-test setup, test accounts, predefined keypairs and snapshot redactions.
  • The project is Rust-based, so it suits teams prepared to work with Rust and WebAssembly.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up an in-memory wallet for Solana testing

Create a testing-oriented wallet that can sign transactions and messages without user interaction.

Before you start

  • Rust and a WebAssembly-oriented Solana project.
  • A Solana RPC client and a generated keypair, as shown in the repository example.

Steps

  1. Create a Solana RPC client with an RPC URL.

  2. Generate a keypair.

  3. Instantiate MemoryWallet with the client and keypair.

  4. Use the wallet for signing transactions or messages in the test or prototype.

Expected outcome

A memory-based wallet setup suitable for browser-based testing and prototyping.

Guide limitations

  • The repository describes this wallet as primarily for testing and does not establish production wallet-security properties.
