About this event

This session explores ERC-8009, an Ethereum standard replacing blind signing with verifiable constraints. Attendees examine clear-signing approaches for hardware wallets and multisig solutions to enhance security. The workshop discusses combining these methods to achieve overlapping protection against exploits.

Full description from organizer

redduck.io is hosting an event dedicated to clear signing and ways to achieve it, including the recently suggested ERC-8009 standard.Blind signing is the single biggest security threat facing everyday Web3 users and protocol teams. Hardware wallets, commonly thought of as an ultimate security solution for wallet security, are prone to a very specific yet highly effective attack called "blind signing"It's exactly what happened with ByBit, when they lost over a billion dollars (1B$) in an exploit. Join us during Blockchain Week Bulgaria for a practical, dual-track session exploring ERC-8009 (Proxy Clear Signing) - the open Ethereum standard that replaces blind signing with on-chain, verifiable outcome constraints, and other modern standards and solutions dedicated to clear-signing. Co-hosted by the co-authors of ERC-8009 (erc8009.xyz), this event breaks down how enforcing balance-delta checks helps make the security protocol-agnostic and how hardware wallets (like Trezor and Ledger) and multisig solutions (Safe) can achieve this integration.Various clear-signing approaches will be examined with their trade-offs, as well as it will be discussed how to combine them together to achieve ultimate overlapping security. Whether you're a crypto user looking to keep your cold wallet safe or a security researcher looking for wallet security solutions, or even a developer currently working on similar standards, you're welcome to visit the event and enjoy the workshop with catering included.
