Fhenix Upgrades Sedona With Confidential FHE to Keep Balances Hidden From AI Agents

Cryptographic Security Upgrade

Sedona, a self-custodial trading level and neo-bank, announced a concern with Fhenix to integrate Confidential Fully Homomorphic Encryption (FHE) infrastructure into its Arbitrum-based system. The institution said the upgrade volition guarantee cardinal fiscal information is encrypted by default.

The integration, announced July 15, replaces Sedona’s existing information exemplary based connected trusted execution environments with afloat homomorphic encryption, according to the companies. Sedona said the alteration is intended to support idiosyncratic balances, portfolio positions and artificial quality cause spending limits encrypted adjacent during processing, reducing reliance connected trusted hardware oregon operator-based models.

“Sedona is precisely the benignant of exertion Confidential FHE was built for,” said Guy Itzhaki, main enforcement serviceman of Fhenix. “Trading platforms and fiscal applications request privateness that extends beyond transactions to balances, positions and progressively the parameters that autonomous agents run within. By moving from trusted hardware to cryptographic guarantees, Sedona is showing however confidential concern tin go a autochthonal capableness connected Arbitrum alternatively than an optional feature.”

Sedona, founded by Tyler Maxwell, offers spot trading, perpetuals and structured products. The level is migrating from the Seismic ecosystem to Arbitrum. Sedona said the deployment volition hap aft that migration is completed, shifting the platform’s privateness exemplary from hardware-based spot assumptions to cryptographic guarantees.

In a statement, the companies said the favoritism is important for some users and developers. They noted that galore backstage decentralized finance solutions trust connected trusted execution environments, which necessitate users to spot the underlying hardware, oregon connected committee-based approaches that necessitate spot successful a acceptable of operators. Fully homomorphic encryption enables computations to beryllium performed connected encrypted information without revealing it, the companies said.

Under the integrated model, Sedona users’ balances and positions volition stay hidden from AI agents executing wrong the system, arsenic good arsenic from different parties.

“We started with TEEs due to the fact that they were the astir applicable mode to present privacy, but our extremity has ever been to region spot assumptions wherever possible,” Maxwell said. “Fully homomorphic encryption lets america support delicate fiscal information done mathematics alternatively than hardware, providing a overmuch stronger instauration for the aboriginal of self-custody.”

Sedona said the method integration is ongoing. Details connected timing for the rollout connected Arbitrum were not provided beyond the connection that it volition travel completion of the migration.
