## Description

This Ledger conference session, led by developer advocates Etienne Waldron, introduces Ledger’s mission to secure Web3 through hardware wallets and new initiatives. The focus is on three hackathon tracks: Clear Signing, Hardware Integrations, and Documentation. Clear Signing addresses the risks of blind signing by enabling human-readable, transparent transaction details using JSON files, which developers can create and submit for bounties and prizes like the Ledger Flex. The session demonstrates the JSON creation tool, explains the review process, and encourages improvements to the tool.

The Hardware Integration track invites developers to use the new Device Management Kit for integrating Ledger devices with popular Ethereum libraries or building new apps. The Documentation track seeks contributions to enhance Ledger’s developer resources. Q&A covers review times, device access, and compatibility, emphasizing that clear signing works on all Ledger devices, with the best experience on newer models.
