External resources
Where to find the standard, tools, and SDKs for Clear Signing. Use this as an index when you need a specific resource while working.
The standard
clearsigning.org is the canonical home of Clear Signing — the ERC-7730 specification, the registry, governance, and the ecosystem. Start there for anything about the standard itself.
Ledger tools
Use these to create, preview, and validate your descriptors.
The JSON Builder generates descriptors visually, the ERC-7730 Tester previews them on a real Ledger signer or the Speculos emulator, and the erc7730 CLI validates and formats files locally (requires Python 3.12 or higher).
Community tooling maintained by other stewards — Sourcify’s preview and TypeScript library, Cyfrin’s Clearsig, and a Rust library — is listed on clearsigning.org/build .
Ledger SDKs
For integrating Clear Signing into a wallet or signing interface.
Token support
Check the supported token list before requesting a new token, and use the ledger-live repository to contribute token icons. See How to add token support.
