surfpool

TL;DR

surfpool is to solana what anvil is to ethereum: a blazing fast in-memory testnet that has the ability to point-fork Solana mainnet instantly.

Design

surfpool uses the low level solana-svm API through the excellent wrapper LiteSVM. This approach provides greater flexibility and significantly faster boot times.

surfpool is also available as a library on crates.io - facilitating its integration in other projects.

Getting Started

Install surfpool from crates.io:

$ cargo install surfpool-cli

Start a local validator / simnet:

$ surfpool run
