dApps Clear Signing implementation with ERC-7730

Overview

This guide will walk you through the process of implementing clear signing for ERC-7730 on EVM chains. This implementation uses a registry of smart contract metadata files.

After your changes are merged, the Ledger generic parser will integrate them, making them available on Ledger devices such as Ledger Flex and Ledger Stax. The “generic parser” serves as the middle-layer deployed on the Ledger infrastructure to read and parse your JSON files.

This preview example shows how clear signing operations will be displayed:

5. Await approval and merge your changes.

Step 1: Fork the Official Registry

• The official registry is hosted on GitHub: ERC-7730 Registry.

Step 2: Add a Metadata File

• Describe your smart contract data according to the ERC-7730 standard.
• Refer to example files available in the registry directory.
• Follow the JSON schema and specification in the specs/erc7730-v1.schema.json and specs/erc-7730.md.

Step 3: Preview Your Changes

• Consult the developer preview README for instructions on setting up the preview environment.
• Run the web application locally to preview your changes.

Step 4: Submit a Pull Request

• Review the PR requirements detailed in the README.
• Automated checks will run to provide feedback on your files.
