Devnet can run blockifier with native execution via the cairo_native Cargo feature. Enable it when building or running:
- Build:
cargo build --features cairo_native - Run:
cargo run --features cairo_native -- <args>
When enabled, startup logs include cairo_native enabled: blockifier will use native execution.
Simplify the installation, spawning and usage of Devnet in your tests by relying on the official JavaScript wrapper. Read more here.
