The idea of blockchain interoperability seems to be gaining traction as developers stir up conversation about the long-awaited link between Ethereum (ETH) and Cardano (ADA). According to Midnight developer Sebastien Guillemot, blockchain is: positioning It itself acts as a cross-chain and computational layer and can work with existing wallets from both networks.
Cardano and Ethereum: “Midnight Glue”
Guillemot explained that implementation will allow for the following: midnight It acts as a privacy layer or bridge between both blockchains. He said that Ethereum and Cardano wallet users do not need to switch ecosystems and can interact without worrying about privacy.
Midnight developers indicated that their team has already implemented the key cryptographic features needed for cross-chain interactions.
What if you could connect your Ethereum and Cardano wallets directly from Midnight? 👀
Midnight is working towards exactly this. Hash function support is one of the important steps and we have just completed it ✅

Midnight may have completed the “hash function” required to verify data from various blockchains. In this case, it involves integrating Ethereum's Keccak and Cardano's Blake2b functionality.
This also includes the ability to verify correct ownership of wallets across both chains without compromising users' personal information.
“Privacy should be at your fingertips, no matter which wallet you have installed,” Guilmo stressed. This means that users are free to keep their existing Ethereum or Cardano wallets as the Midnight protocol is not forced on any users.
Guillemot said Shield Technologies is providing technical support for Midnight's privacy protocols. However, the primary responsibility for private calculations rests with Midnight. The chain positions itself as a “privacy-first” smart contract layer.
The developer believes this move is an expansion of Midnight’s vision as a privacy-focused Cardano sidechain.
It also builds on the NIGHT token airdrop of over 50 million addresses. He said it may be necessary to “invent some new tents” to accommodate the upcoming massive expansion.
Charles Hoskinson's privacy vision for Midnight
Interestingly, Cardano founder Charles Hoskinson had highlighted in May 2025 how Midnight's privacy layer could actually help billions of users.
We explained our strategic partnership with Brave Wallet. Hoskinson pointed out: Brave has 84 million users You can benefit from encryption protection while online.
Meanwhile, Midnight continues to set milestones; record remarkable growth As privacy hype grows in the broader cryptocurrency space. Recently, the trading volume increased by 81.94% to $8.98 billion, and the price soared by more than 20%. Midnight's growth is also driven in part by strategic partnerships.
