The video explains the problem of blind signing in crypto wallets and introduces ERC‑8009, a standard that lets users sign based on the expected balance change rather than raw contract data. It is aimed at developers, wallet creators, and security‑focused users who want clearer transaction approvals.
What it covers
Blind signing lets users approve unreadable transactions, leading to fund loss.
ERC‑8009 (Proxy Clear Signing) requires signing the expected balance outcome.
On‑chain proxy cancels the transaction if the actual result differs from the signed terms.
Demonstration of ERC‑8009 integration with Trezor and Ledger hardware wallets.
Guidance for developers and wallet teams on adopting the open‑source standard.
