Scrypto v1.2.0

Scrypto v1.2.0 introduces various features and enhancements, targeting the bottlenose protocol update.

Starting from this version, Scrypto and Radix Engine crates are published to crates.io.

New Bottlenose Features

Bottlenose protocol update introduces two new features that can be used by Scrypto blueprints.

There is a new native blueprint AccountLocker, which makes sending resource to accounts easier. See this doc for more details. A corresponding stub is added to Scrypto library.

A new method get_owner_role is added to every global component. Here is an example of how to get the owner role of a component:

let owner_role = global_component.get_owner_role();

Radix CLIs

The simulator is rebranded to radix-clis, featuring the following tools:

• resim - A ledger simulator to play with Radix Engine features
• scrypto - A tool for creating, building and testing Scryto code
• rtmc/rtmd - Radix transaction manifest compiler and decompiler
• scrypto-bindgen - A tool for generating stubs for the blueprints of a package

Here is the new way of installing Radix CLIs:

cargo install --force radix-clis@1.2.0

Pretty Manifest Compilation Error

Radix CLI rtmc now prints pretty error message and highlights the problematic parts.

New Scrypto Compiler Library

A new library scrypto-compiler is introduced to standardize everything around Scrypto compilation. This crate is used by Radix CLIs, scrypto-builder and scrypto-test, to provide consistent behavior. It is now available for public use.

Scrypto Testing

Various enhancements are made to Scrypto testing libraries.

• scrypto-unit is merged into scrypto-test
• TestRunner is renamed to LedgerSimulator
• TestEnvironmentBuilder is introduced for configuring the environment prior to creation
• SubstateDatabaseOverlay is added to enable testing and simulation on top of a real Node database
• Package is renamed to PackageFactory
• Scrypto tests now can specify a CompilerProfile, indicating whether standard or fast Scrypto compilation should be used

Manifest Builder

Two bug fixes for the ManifestBuilder utility

• Fixed the issue that deposit_batch consumes named buckets, #1702
• Fixed the issue that prevents creation of RUID NFTs, #1701
