Airdrop glacier: Cardano injured users, Charles Hoskinson reacts

A bug in the Ledger portfolio software prevented Cardano users from claiming their Drop glacier tokens. According to Charles Hoskinson, founder of Cardano, the problem remains unresolved, although it was reported in July.

Message signature problem on Ledger wallets

The Ardrop du Token Night is a key part of the wider deployment of Midnight, covering eight ecosystems to ensure fair access. While most portfolios work without problem, Cardano users using LEDGER portfolios have encountered difficulties due to messages of messages.

To make a complaint, users must sign a message in accordance with the CIP-8 standard-a format used to confirm the property of a portfolio. However, LEDGER devices are currently limiting the size of the messages to 31 bytes, while the one required for DROP Glacier reaches 251 bytes.

This incompatibility means that LEDGER users cannot complete the verification stage and cannot, for the moment, access their Night tokens.

Coordinated solutions to ensure the compatibility of Ledger with Cardano

Charles Hoskinson noted that the Ledger problem was reported in July, but without official correction in sight, his team introduced a temporary solution. The solution takes up techniques already used in the NFT space. He said,

This is a specific problem in Cardano with Ledger software. We asked for an update in July, but no calendar was communicated. In the meantime, we use a common method in the NFT ecosystem: signing an undifferentiated transaction (called zero) containing the GD payload of 251 bytes in the form of metadata.

In a separate update, Bob Blessing Hartley, Technical Director of Shielded Technologies – The team behind the Midnight network – spoke of a different approach. He said that they had tested hundreds of combinations of hardware and software wallets during the development of the Airdrop.

They found that adabase complaints via material portfolios did not correspond to the principles of security on which the Dropper Glacier program is founded. To resolve this, the Hartley team has created a new claim method specifically adapted to Ledger users.

Their solution is also based on a value without value, including the details of the complaint in the form of metadata. This information is clearly displayed on the LEDGER screen so that the user can see precisely what he approves. Hartley has confirmed that the approach has been widely tested in the Cardano community and meets all the required security standards.

Fahmi Syed, president of the Midnight Foundation, recognized the Message signature problem. He said that the implementation of CIP-8 by LEDGER raises security concerns and that the protection of user assets remains a major priority. The two teams continue to work in close collaboration to monitor the situation and consider longer -term improvements.

The complaint process and the distribution of tokens are not affected

Despite this technical setback for Ledger users, the Drop glacier distribution calendar remains unchanged.

• Night tokens allowances were based on an ADA historic snapshot – The wallet amounts are already fixed.
• Complaints can be made at any time during the 2 month window without affecting the tokens amounts.
• A secure solution ensures that LEDGER users can always claim tokens despite the size of the messages.
• The revised complaint path is during the final audit and should be operational during the week of August 25.
• According to Syed, more than 120 million Night tokens were claimed a few hours after the launch, with a strong commitment to the eight channels supported.

In the meantime, the team invites users to avoid unofficial or not verified platforms. There have already been attempts by fraudulent sites to imitate the Drop glacier interface, potentially targeting Ledger users. Measures are taken to detect and eliminate these threats to protect the community from scams.
