Midnight privacy-vault demo requires outside signers to release Ethereum tokens

Current overview (not historical)

AI overview

A Midnight privacy-vault demo shows that releasing Ethereum tokens requires outside signers, with underlying assets remaining on Ethereum. The SIG Network threshold signature scheme requires users to destroy shielded claims before MPC service providers can sign transfer transactions. If a transfer fails, the claim can only be recovered after MPC service provider verification.

    Midnight privacy-vault demo shows Ethereum token withdrawal requires external signers

    Report first recorded Oct 22, 22:07

    Withdrawals from SIG Network’s experimental Ethereum vault, which holds underlying ERC20 tokens on Ethereum, require a signing network because the holder's authorization alone cannot execute the transfer. Users must first burn a shielded claim, and the subsequent external transfer needs a signature from an independent threshold of signers via an MPC service. Furthermore, failed-transfer recovery requires an attested response from the MPC service to potentially restore the claim.
