Build Clear Sign Metadata

Accessing the Builder

1. Visit the Tool Point your browser to the ERC-7730 JSON Builder at Kai-Sign enhanced builder: beta.kaisign.xyz.

2. Choose “I already have Clear Sign JSON file” (optional) If you’ve previously generated your metadata, click the “I already have Clear Sign JSON file” link to upload it directly.

Entering Contract Details

1. Select Network (chainId)

   • A dropdown lets you pick the blockchain for the metadata ChainID (e.g., Ethereum Mainnet, Arbitrum, etc.).

2. Input Contract Address or ABI

   • Paste your contract’s address (e.g., 0x…) or the full ABI JSON.

   • Click Submit

Operation Description (Legal Name & URL)

• Input:

  • Legal Name: Your project’s legal entity (e.g., “MyDAO Foundation”)

  • URL: Link to your org’s website or Github

Defining Operations to “Clear Sign”

For each operation you want users to verify:

Confirm Operation

• Click on the operation (e.g., transferOwnership) in the left-hand menu to add it.

Filling Out Metadata Fields

For each operation you selected, fill in these fields:

Operation Display Name / Intent

• Input: A human-readable label, e.g., &#xNAN;“Transfer contract ownership to [address]”

• Field: JSON-pointer to the argument.

• Label : Display name for the parameter.

• Required (true): Wallets must show this field.

• Format (addressName): Specifies it’s an address that should be name-resolved.

• Address Type (["wallet","eoa"]):

  • eoa: Externally Owned Account

  • wallet: Account controlled by the wallet software

  • (Do not include token or collection here because this parameter expects a user address, not a token contract or NFT collection.)

• Sources (["ens"]):

  • Only ENS is crypto-verifiable on-chain, so local sources (which malware could spoof) are omitted

Reviewing & Exporting

1. Review

   • Once all operations and parameters are defined, click Review.

   • The builder shows a preview of how it will look on a Ledger device.
