Executor

Bare-bones Solana transaction playground, based off of Neodyme's poc-framework.

Features

• Execute a transaction or a batch of transactions locally, and retrieve intermediate states (convenient to simulate e.g. Jito bundles execution)
• Automatically load all accounts involved in the transaction(s) from the specified cluster
• Consumable as:
  • Rust crate
  • HTTP server wrapper & client to decouple version sets, to avoid unnecessary dependency hell when possible
• Fetch account(s) through HTTP interface

Gotchas

• This does not spin a local validator, and instead simply exposes a Bank to execute transactions and interact with accounts.
• Depending on your needs, you might be better off using (in increasing order of abstraction):
  • Neodyme's poc-framework
  • solana's ProgramTest utility
  • solana-test-validator
  • RPC simulation
  • devnet
  • PROD!

Workspace breakdown

• core/: transaction execution logic
• server/: wrapper server exposing the core logic through HTTP
• client/: client for above server
• client-gen/: library exposing a single macro to generate a client within your own crate, and avoid binding the solana dependencies (useful in case of dependency pinning hell, even though versions are compatible)
• example/: sample usage of the client-gen
