Midnight privacy-vault demo relies on outside signers to release Ethereum tokens
- —Withdrawal burns the shielded claim before the external transfer is signed by the MPC service
- —Refunds on failure require an attestation verified against the vault's response key
- —Ethereum integration runs on stagenet; mainnet awaits ledger v9 per roadmap
- —Deployer can replace a stuck transaction's nonce, but that also needs a signature
Why it matters: The design shows that holding assets on Ethereum does not guarantee the ability to move them without trusting external signers.
