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
