Scroll-SDK

Scroll SDK is a seamless all-in-one software development kit for carrying out bridging operations between Scroll blockchain (L2) and Ethereum blockchain (L1). With the SDK developers can simply integrate bridging features in their dApp without the hassle to implement from the ground up.

Testing Locally

** Note: These steps for working on the SDK locally are valid till the SDK is published, Changes would be done on the README.md to that effect

Core

• Clone the repo to your local machine
• Navigate into the "core" directory
• Create a ".env" file in the root of this directory. You can use the ".env.example" as a guide. Populate the variables with their relevant values.
• Install the TypeScript execution engine if you haven't already. You can use the npm install -g ts-node command
• Now generate the types using the ts-node src/utils/genTypechain.ts command
• Install the depencies using the yarn command
• Build by running the yarn build command
• Test by running the yarn test command

Scroll-Bridge-SDK

• Ensure you've built the Core module before attempting this
• Navigate into the "scroll-bridge-sdk" directory
• Create ".env" file in the root of this directory. You can use the ".env.example" as a guide. Populate the variables with their relevant values.
• Install the dependencies using yarn
• Run the tests using yarn test
