Sebastien Guillemot, a developer for the Cardano-based privacy network Midnight, has sparked excitement by suggesting the project could serve as a bridge between the Ethereum and Cardano ecosystems. In a social media post on December 24, 2025, Guillemot stated that Midnight is working towards enabling direct connections between Ethereum and Cardano wallets from its platform, with privacy as a core feature. He announced the completion of a key cryptographic step: integrating Ethereum's Keccak and Cardano's Blake2b hash functions to verify data across chains.
"No matter which wallet you have installed, privacy should be at your fingertips," Guillemot emphasized, clarifying that users would not need to switch their existing wallets. The vision positions Midnight as a privacy-first smart contract and cross-chain computation layer. Shield Technologies is providing technical support for the privacy protocol.
In related developments, Cardano founder Charles Hoskinson directly addressed community confusion regarding Midnight's native token, NIGHT. Following speculation that NIGHT could replace ADA, Hoskinson firmly rejected the idea, stating it misunderstands Cardano's layered design. He explained that NIGHT is designed to power the Midnight privacy network's specific operations and governance, while ADA remains the foundational asset for Cardano's base-layer security and settlement.
Hoskinson framed Midnight as an expansion layer that extends ADA's utility into privacy-sensitive use cases like healthcare and finance, attracting new developers and institutional adoption to the broader Cardano ecosystem. He urged the community to view the tokens as complementary, not competitive. Midnight recently conducted a NIGHT token airdrop to over 50 million addresses and has seen significant growth, with its price soaring over 20% and trading volume spiking 81.94% to $8.98 billion amid rising hype for privacy solutions in crypto.
