Midnight and Sig Network Connect Private Logic to Ethereum Liquidity
A Midnight contract can control an Ethereum account through threshold signing while user-level balances and records remain shielded; current availability is on stagenet.

Midnight Foundation and Sig Network announced on October 28 a path for Ethereum applications to use private logic without moving their underlying assets to another chain. A Midnight contract controls an ordinary Ethereum account through Sig Network’s threshold signers; Ethereum handles settlement while individual balances and activity records remain on Midnight.
The public Ethereum leg still exposes the account’s transaction amounts and timing, so the design does not make Ethereum settlement invisible. Midnight says Sig Network is live on Midnight stagenet for deposits, Uniswap swaps, Aave supply and withdrawals. That is a development-stage deployment, not evidence that unnamed production applications or institutions have adopted it.
