## Radix Engine - Scrypto Assets

## Genesis assets

The Genesis Helper and Faucet were compiled with the v1 deterministic scrypto builder, and deployed
as part of genesis to the ledger.

The exact assets can can rebuilt with the following script, checked out against the babylon
version of the ledger: https://github.com/radixdlt/radixdlt-scrypto/tree/release/babylon

For now, to avoid confusing automated tooling, we have deleted the `Cargo.toml` files and the
`Cargo.lock` file for these genesis assets, and just kept the `lib.rs` source files around for
reference.

```bash
#!/bin/bash
set -e

cd "$(dirname "$0")"

# The genesis blueprints were compiled with Scrypto v1.0.0. To reproduce the same
# wasm files, the Scrypto source code must be placed at `/src` and the blueprints workspace
# source code must be placed at `/src/assets/blueprints`.

    git clone https://github.com/radixdlt/radixdlt-scrypto $SCRYTPO_SOURCE_DIR
    (cd $SCRYTPO_SOURCE_DIR; git checkout v1.0.0)
