Run it locally

Requirements

• Rust with the Solana platform tools (cargo build-sbf), and rustc 1.98 or newer for the LiteSVM tests
• Anchor 1.2.2 for the IDL
• Node 20 or newer

Build and test

export PATH="$HOME/.local/share/solana/install/active_release/bin:$PATH"

# LM-OTS against the RFC 8554 vectors
cargo test -p lmots --features sign

# program binary
cargo build-sbf --tools-version v1.58 --manifest-path programs/quantark/Cargo.toml --sbf-out-dir target/deploy

# program tests on LiteSVM
cargo +1.98.1 test -p quantark --test flow -- --nocapture

# client checks, then the full flow on a local validator with Meteora's mainnet DBC binary
cd app && npm run test:lib && npm run test:localnet

Rebuild the IDL after changing the program:

RUSTUP_TOOLCHAIN=1.98.1 ~/.avm/bin/anchor-1.2.2 idl build -p quantark -o target/idl/quantark.json
cp target/idl/quantark.json app/lib/idl/

Local preview

bash app/scripts/dev-localnet.sh

Starts a seeded validator with the canary fixtures, the basket, a launch config and sample coins, then serves the app on localhost:4810.

Deploy to devnet

bash app/scripts/devnet.sh

Needs about 3.5 devnet SOL on the deployer key. It deploys the program, seeds the basket and launch config against Qanary’s devnet canary, and writes app/.env.production.local.
