Claim Midnight - https://t.co/WaOGszcNXb
To sign the unique claim message in the Lace Cardano wallet (which proves ownership of your origin address to complete the claim), use the built-in message signing feature introduced in Lace version 1.16. This allows you to create and sign messages directly in the wallet without connecting to a DApp, making it suitable for trustless claims like the one described.
Prerequisites
Ensure your Lace wallet is updated to at least version 1.16 or later (check in the wallet settings or download the latest from https://t.co/pGAiyo5oXU).
The wallet must contain the origin address (the one you're proving ownership over). If using a hardware wallet (e.g., Ledger connected to Lace), note that message signing may not be supported—consider using a software-only wallet or CLI alternatives if needed.
Have the unique claim message ready (provided by the claim interface, bundling your allocation size, destination address, and T&C hash).
Step-by-Step Instructions
Open Lace Wallet: Launch the Lace browser extension (or desktop/app version if available) and unlock your wallet with your password or biometrics.
Navigate to Message Signing Section: Go to the area in the wallet UI dedicated to message signing. This is typically found under "Settings" > "Advanced" or a similar developer/tools section (the exact label may vary slightly based on updates, but look for options related to "Sign Message," "Create Message," or "Advanced Features").
Create a New Message: Select the option to create or input a new message. Paste the unique claim message (the full text bundle) into the provided field. Ensure it's entered exactly as given, without modifications.
Select Signing Address/Keys: Choose the origin address from your wallet as the one to sign with. This links the signature to the keys proving your ownership.
Sign the Message: Review the message for accuracy, then confirm and sign it using the wallet's built-in functionality. Lace will handle the cryptographic signing (following Cardano's CIP-8 standard) and generate the output.
Retrieve the Signed Output: After signing, Lace will display the signed message details. Key elements to copy:Signature: Usually the COSE_Sign1_hex value (a long hexadecimal string).
Public Key: The corresponding public key hex for verification.
Complete the Claim: Return to the claim interface, paste the signature and public key into the respective fields, and submit to finalize. The site will verify the signature against your origin address.
